Prop shaft moves in and out

Re: Prop shaft moves in and out is this normal? Well man if it is the problem...and you are just dead set on fixing something that really may not need fixing, for god sakes dont pay that much for it, just buy another foot and be done with it. those can be had cheap off ebay and other places like Craigslist In a nutshell, it means that your prop shaft is turning, but your propeller is not. There is a rubber insert that goes between the propeller and the prop shaft. The rubber insert is there to help absorb any shock that is caused when you hit something like a rock, sand or mud

I have a 77 Evinrude 70 horse, the prop shaft moves in and out almost 1/4. I am wondering if this is normal or cause for concern. Everything else seems ok with the motor. Any advice is appreciated. W. Will Bark Lieutenant. Joined Aug 1, 2010 Messages 1,470. Apr 28, 2011 # Assuming you mean that the prop moves in and out on the shaft, This is normal on all outboard motors. You also stated that you tighten the prop as tight as you can. That is a no no, you are.. It moves 1/8 in and out. It seems the fold down ears that hold the nut on were not pressed down as much as they were last year when I re-torqued it. The shaft itself will move about 1/16 in and out with prop off. Where's the thrust washer If it can move at all then it can also move back in reverse fouling the rudder or even coming right out the tube in nothing to stop it. It should be secured by at least recessed pinching screws or pinned through the side of shaft never through the middle. 20 Oct 2012 #

prop is tight, the slack or play is the whole shaft moving in and out, and seems too affect the reverse engagement at times. Marine Mechanic: Whitecap36 , Marine Technician replied 10 years ago Ok good, This play then as been there even before you changed the prop out Here is the problem, with the prop installed as per instructions with their specified inner thrust washer the prop has in and out play on the shaft with the nut torqued down (maybe 5/16 inch of play) The rep at Merc said that is how the props fit on a Merc but wasn't positive with a Yamaha All of the QC-3328's I have are rock solid. No play at all. Well, tell a lie, one of that did some tree trimming and is no longer in service has a slight click when I waggle the top of the prop shaft from side to side....that's got to tell me something as it was one of the noisy motors... I suspect the play is an indication of a suspect bearing

Propeller Shaft | Function , types , Components and Requirement. The drive shaft (also called propeller shaft or prop shaft) is a component of the drive train in a vehicle, with the purpose of delivering torque from the transmission to the differential, which then transmits this torque to the wheels in order to move the vehicle Place a piece of wood — Jansen has a nice pine 4x4 — between a prop blade and the anti-ventilation plate to keep the prop from turning when you loosen the nut. Spin off the nut and lock washer and then slide the prop off the shaft. On our Merc, the composite Flo-Torque prop hub slides out of the prop first You can count on Prop Shaft Supply for all of your OEM driveline needs. Prop Shaft Supply was incorporated in October of 2000, but we have over 30 years of experience in the driveline business, serving large OEM's (Original Equipment Manufacturers) as well as industrial accounts and small driveline repair shops. With our location in I changed the prop and that did not help. I noticed that there is a lot of in and out play in the prop shaft. So much that the inward play during thrust was causing the prop to rub against the motor housing. I put in a couple of pegs to shim out the prop, which stopped the rubbing, but did not help the vibration Then I grabbed the prop and checked for the backlash and it doesn't have it anymore (no movement in our out) so I decided to remove the prop to see if there was something restricting it but it was all clear. Even with the prop off the shaft alone didn't move any amount. I have removed the gearcase as it's time for an impeller change so I will.

Prop shaft moves in and out is this normal? Boating

Check the UJ in both planes to ensure that it moves consistently. If it feels tight, gently tap the arms of the yoke with a copper mallet to 'open' it up. If there's any play between the yoke and the UJ's cross-shaft, then a needle-roller bearing is out of place. Grease the joint before reinstalling the prop However I've seen prop shafts that would move quite a bit. If you pulled outward on the shaft. If memory serves me the entire shaft moved but the prop wasn't actually moving on the shaft. In most cases there is a thrust washer that is part of the hardware used to install a prop. No washer can damage the gear case and/or the prop will move on. Your prop should not be moving in and out on the propshaft. It should be tight. Depending on your outdrive, there could be a thrust washer that should be on the shaft between the prop and the outdrive housing. You will usually find this thrust washer on Mercruiser Alpha and Bravo II drives, and Volvo SX single prop drives A driveshaft is a cylindrical shaft that transmits torque from the engine to the wheels. They are most commonly found on rear-wheel drive vehicles and connect the rear of the transmission to the driveshaft. As the output shaft of the transmission rotates it spins the driveshaft, which then turns the differential ring gear to rotate the wheels Looks like the prop side comes in at a angle. I would treat this like a pto shaft which all have a locking collar to lock u joint to shaft. Some use a through pin some use a through bolt. Because the prop is angled the prop shaft or hole on u joint can wobble out eventually. A pillow block support on prop side would help the situation

Help! Boat Prop Has Play In It - Troubleshooting Tip

In this state, all of the propeller force is pushing the boat forward. When the trim button is pressed down, the gearcase moves closer to the transom until it bottoms out at about negative 6 degrees from zero trim. Now the prop shaft is aimed up 6 degrees, and some of the force is lifting the stern of the boat PROPELLER SHAFT: FUNCTION, TYPES, COMPONENTS AND REQUIREMENTS. The drive shaft (also called propeller shaft or prop shaft) is a component of the drive train in a vehicle, with the purpose of delivering torque from the transmission to the differential, which then transmits this torque to the wheels in order to move the vehicle Oscillating propeller shaft causing stuffing box clamps to loosen and work free, flooding or sinking the boat. Wear or worn out engine mounts cause drive shaft misalignment to stern drive, causing universal joints and gimbal bearings to oscillate and wear out The only additional thing that needs to be removed is the prop itself. The idea is to make a sleeve out of 1″ pipe that fits over the prop shaft to push the bearing out. I used a 4 section of pipe that is small enough to slide through the strut. In order to get it on the prop shaft, I had to split the pipe If this happens, I've heard the best way to get the propeller to move is to spray the shaft and behind the propeller on the shaft with WD40. Let that sit for a few hours or overnight. Apply a little more WD40, and then using a tool like the ACME clamp prop puller, try to get the propeller to pop free

One of the simplest and most important parts of a vehicle is the driveshaft. Responsible for transferring the output of the transmission to the axles, it is essentially a shaft that drives the vehicle. Though it has a basic function, it plays an incredibly crucial role in vehicle operation and is the link between a revving engine and a moving car The only reason I know all this is because a buddy of mine bought an old Range Rover kinda blindly and found out the front drive shaft was taken out. usually people only take out a drive shaft if the differential is trashed. Once the front drive shaft is removed, then you trash your transfer case Fortunately there's a pretty handy way to remember things. Prop down equals bow down. Prop up equals bow up. Pull. Remember that when you're driving a car you're on a two-dimensional plane. You don't have to worry about any up or down motion. Because your prop is underwater and the trim moves up and down in the water you have that added. Yesterday after pulling the boat out I spun the prop listening for noise. No noise but I discovered that the prop could be slide back and forth on the shaft about 3/16. It also has a little play side to side on the shaft. I am sure the end play is not suppose to be there and that is probably causing the ratchet like noise Governor Control Lever The governor control lever is attached to the blue prop control lever in the cockpit through cables or linkages. When you move the prop lever forward or back, the control lever moves as well. Threaded shaft The threaded shaft is connected to the governor control lever. It looks pretty much like a bolt, and it works the same way

Boat Prop Tight but Still Moves Up and Down? Yahoo Answer

Each unit has an engine, propeller, and steering control. In most units, cables attached to the steering wheel actually pivot the entire motor unit to provide steering. To make it easier to move the boat in and out of the water, the entire motor unit can be pivoted up and out of the water The rear seal on my front differential is leaking but I can't get the drive shaft out of the diff so I can replace it. I took the diff a loose and removed the shaft from the engine side but I can't get it to come out the back of the diff. Is there a trick to getting it out? The shaft will move in and out of the diff about 1/4 on an inch but. The prop shafts bend when impacted with the bottom is great enough. The second number tells how far the prop would move forward in one revolution if there were no slippage in the water. This is the pitch. Once the prop has hit bottom several times, it bends and chips. If the prop is out of balance, it will vibrate, damaging the bearings.

Can a prop shaft move forward

Shaft misalignment is responsible for as much as 50 percent of all costs related to rotating machinery breakdowns. Accurately aligning shafts can prevent a large number of machinery breakdowns and reduce much of the unplanned downtime that results in a loss of production of a 'floating shaft assembly which eliminates strain between the engine, the V- Drive, and the propeller shaft. By using a self-aligning bearing in the front of the V-Drive along with a splined shaft and flexible joint, the shaft can move in and out and also angularly to take up slight engine misalignment (3 degrees maximum) US20080188146A1 US11/882,630 US88263007A US2008188146A1 US 20080188146 A1 US20080188146 A1 US 20080188146A1 US 88263007 A US88263007 A US 88263007A US 2008188146 A1 US2008188146 A1 US 2008188146A1 Authority US United States Prior art keywords assembly drive assembly drive prop shaft Prior art date 2006-08-04 Legal status (The legal status is an assumption and is not a legal conclusion

Propeller Shaft Function , types , Components and

A drive shaft (also called a propeller shaft) is essentially a long rod that is designed to transmit torque from the output shaft of the transmission to the rear differential in a rear wheel drive, four wheel drive, or all wheel drive vehicle. Since drive shafts rotate quickly, they're able to move the rear wheels of your vehicle. The. Most props move in & out some. Most people never check , they just spin em. The prop shaft will have to have a little play to shift. Your prop is tight it's the shaft that's moving a little. NORMAL!!!!! We only sell the Best. Ranger, Xpress, Yamaha, Suzuki, Tohatsu Only two of us aboard who discussed and then speculated maybe we just had something wrapped round the prop and perhaps running briefly in reverse would shift it. But in reality the shaft coupling was loose and reverse just put a pull on the shaft instead of push, and wound the shaft out of the coupling so losing our drive altogether A propeller shaft, or propshaft, connects the rear axle to the gearbox on front-engined rear-wheel-drive cars. At each end of the propshaft there is a universal joint (UJ), which allows the rear axle to move up and down in relation to the gearbox without bending or snapping the shaft. Some propshafts also have a universal coupling fitted at the centre

The shaft should be centered in the tube - some shims may be needed to support it at the inboard end; The shaft should be straight - check the run-out on V-blocks, or have a prop shop do it; With flex mounts, try t ensure each mounts is loaded evenly - that is to say each mount carries an equal amount of engine weight I took the driveshaft out and took a look inside. I couldn't tell much about the tailshaft bushing with the seal still in the way but I found that the whole output shaft had a bunch of play in it. Moving the output shaft up and down I could see the whole rear bearing moving up and down also This vibration means that the universal joint bearings have now worn enough to allow the driveshaft to move outside its normal rotational path, causing imbalance and vibration. This will be a higher frequency vibration than that of an out-of-balance wheel for example, since the driveshaft turns 3-4 times faster than the wheels In Figure 8-1, the engine delivers torque through its crankshaft to the drive shaft and finally to the propeller shaft. The transfer of torque, or twisting force, from the drive shaft to the propeller shaft is made through gears. The torque devel­oped at the engine is thus delivered through shafts and gears to the propeller

It has a four-bladed/21 pitch prop, 25-inch shaft. Problems- 1. the boat comes out of the hole real slow, it takes 300 to 500 feet to get up. Max rpm's-4000, after about 300 yds the boat starts porpoising without any trim movement Constant-velocity joints (also known as homokinetic or CV joints) allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play.They are mainly used in front wheel drive vehicles. Modern rear wheel drive cars with independent rear suspension typically use CV joints at the ends of the rear axle halfshafts and. The current boat has the shaft just slightly offset so removing the prop allows the shaft to slide out. Getting the coupling off the shaft can be an issue, especially if it hasn't been removed in some time and is rusted One trick is to use the coupling halves as a pusher, i.e. separate the halves, put a socket on the shaft between the coupling.

Thanks for the guidance team, I found the trouble. A broken roll-pin at each end spline connection had allowed the prop shaft to move back enough to fettle the spline on the front diff connection. Eventually, and purely coincidentally, it broke loose not long after I poked around in the front axle The propeller, while a very important part of the system that moves your boat, isn't the only factor contributing to achieving maximum boat speed. The main factors influencing top speed are hull design, weight, trim, and bottom cleanliness; engine horsepower and condition; and propeller style, size, and condition Think about what's happening-an engine-driven propeller is constantly pushing forward against the drive line, transmission and engine mounts. When the engine is shut down and the propeller now freewheels, the drag it creates pulls back in the opposite direction as it tries to pull the propeller and shaft right out of the back of the boat Split Hub Propeller Shaft Couplings; Groco Raw Water Strainers; a longer hose is always better as it allows the packing gland assembly to follow the shaft as it moves during normal operation. The horror stories are out there. Dripless shaft seals of any design can be really nice in some applications and are generally care free, or.

On the outside of the slip yoke, a bearing surface supports the front end of the propeller shaft in a plain bearing, in the transmission extension housing. This enables the slip yoke to move longitudinally and vary the shaft length with suspension movement. 5.5 Universal Joint Half shafts, otherwise known as axle shafts, are fitted in rear-wheel-drive cars only. They give relatively little trouble during normal motoring, although they are highly stressed components. The inner end of the shaft is supported and driven by the differential, and the outer end is supported in bearings between shaft and axle housing. These bearings have either built-in or separate oil seals At low propeller shaft speeds, the marine propeller has a great deal of slip. The propeller turns, but it does not develop much thrust, and therefore it does not require much torque to revolve it. The reason for this is the angle-of-attack that the blades make with the water

The movement causes the angle of the propeller shaft, and the distance between the gearbox and the rear axle, to change constantly. To allow for the constant movement, splines on the front end of the propeller shaft slide in and out of the gearbox as the distance changes; the shaft also has universal joints at each end, and sometimes in the middle your hub could be spun out in the prop also. inside the prop there is a rubber or plastic hub that is designed to give out before damagine other gears and shafts - for example if someone hits a rock or runs aground, the the hub fails and allows the prop shaft to keep spinning or serious damage could be done

Fixing the prop requires pressing out the old hub and replacing it with a new hub. If you have the proper tools, you can do this process yourself The splines may be worn. The yoke transmission extension housing bushing may also be worn. This will let the yoke move up and down with changes in drive line torque. An excessively worn U-joint or differential problem can also cause a similar noise. A whining sound from the drive shaft is sometimes caused by a dry, worn center support bearing My newest prop is a 3 blade feathering prop (it is a Featherstream). I wanted better sailing performance, and this prop has made a huge difference in drag when sailing in light air. I considered 2 blade or 3 blade options, but Featherstream only makes 3 and 4 blade props so I bought the 3 blade one

Removal & Replacement of the Shaft Seals Without Disassembling the Lower Unit : This section deals with either the driveshaft seal below the water pump OR the prop shaft seals which consist of 2 back to back seals of the same size. This back to back method uses one to keep the water out while the other keeps the oil in The drive shaft in your car is what transmits torque from the engine to the wheels. If you have a rear wheel drive vehicle it's going to connect the rear transmission to the drive shaft. The output shaft from the transmission rotates and causes the drive shaft to spin and that in turn makes the wheels rotate thanks to something called the differential ring gear turning The 1GM10 is physically much smaller than the P60 that was pulled out. Both are raw water cooled and both have the same shaft output RPM from the transmission. I did convert the 1GM10 to fresh water cooling.

Great answers from Paulster. I would add: Prop shaft: probably short for propeller shaft (which is the drive shaft that runs the drive or torque all the way from the transmission to the rear axle assembly in rear-wheel-drives).. Drive shaft is the proper name for a shaft that runs from a final drive to a driving wheel, or a shaft between the transmission and an axle The splines on the output shaft should be straight as an arrow. If they are tweeked, it is a good indication that your S/S prop has smacked something. Hard enough to twist the shaft, but not hard enough to break it. A hit that hard can do some pretty heafty damage upstream, also. Time for some major work to be done The total travel (all the way out to all the way in) varies depending on the particular indicator model. For shaft alignment, we typi­cally use dial indicators with 0.250″ - 0.300 total travel. The plunger moves a needle clockwise when pushed in and counter clockwise when let out. The face can be rotated so that the needle points to zero I'm so excited. I finally received the new propeller from Campbell Sailor. I used to have a 2 blade prop and from what I read online, this 3 blade should give me better power when getting in and out of the dock. I have read that some people have found less prop walk as well but I am doubtful of that. Can't wait to give this a try
