Using your digital calipers, restore the engine to the original height per your sketch. Yes, the shaft coupling to transmission coupling needs to fit within several thousandths, but what were talking here is the coupling fit, not the shaft alignment. A power take-off connects the motor to the torque tube. Note that these are made to accommodate both the 1310 and 1350 torque tube series. Again, there may be noises emitting from the engine that do not sound quite right. So take a look all over our web site and I am certain you will definitely spot the things you are trying to find in the quickest time possible.
Because of the rubber mounts, the engine will not be in the same position when running as it is when stopped, when the alignment is made. Two series are available, a 1310 and a 1350. Still, in some cases it's enough to keep an old boat going for a few more years. The current mounts are 100mm center holes, the new ones are 110mm center holes. Using a flat-blade screwdriver, separate the coupling halves an inch or so to allow the engine to move free of the shaft. Sterndrive Engineering is the largest supplier of replacement outdrives in the world. Again, this is primarily a power boat problem because the impact forces generated on the bottom of the hull require substantial stringer reinforcement.
In 2012, David Pascoe has retired from marine surveying business at age 65. Note that its badly cocked to the left. However, the most common symptom is just excess noise. On the other hand, a badly wobbling shaft means something's wrong. Im wondering if this is a feasible thing to do or am I better off keeping the existing engine placement on the brackets. The subject of alignment is really not very complicated, but it does involve several other factors which most people are not aware of.
The strut in photo at right carries the same size shaft and prop, both on a 40' boat. Thank you for your interest in the company and its transom repair products. While an aftermarket replacement mount will fit your engine, it may not necessarily damp the engine vibrations over the operating range. This is more common than you might think. I use an air chisel.
This type of mount is one of the least effective types. Since neither the shaft nor the engine is held rigidly in place, there's not much point in attempting to perfectly align the shaft with the engine, is there? This is because shafts with multiple bearings can bend it into a favorable position while overall it is still badly out of alignment. Before removing each mount, note the position of the enlarged mounting hole or slot on one end of the old mount. This is not as difficult as you might think if you have the right tools and equipment available. Note also that the long stud can create a substantial lever if the engine is mounted up toward the top. If motor mounts break off completely from an engine, and are not just loose or cracked, an engine can shift from one side to another, bouncing about.
With the latter, a marine transmission should be used on the motor. Pour it into the hole you drilled while using a stick to stuff the hole until it wont take any more of the slurry. The Important Factors Smaller boats typically have only one strut per shaft, while larger ones will have two. After exceeding my patience in waiting for a mechanic to do this, I'm about to attempt it myself. Whatever you do make sure that the mixture does not cure at a higher rate then recommended. If the shaft moves up and down, its worn and is ready for replacement. It's worth extra rip and tear work to do it this way.
Take a wood bit about 1. The wood that was above the stringers floors, spacers, etc. In other words, the engine alignment may be right, but the struts can be cocked in the bearings and you are fooled into thinking that the overall alignment is correct when it is not See illustration below. For the above process to work the wood must be reasonably dry and oil-free. Now, you may look at a 1.
Soak the bolts in some rust remover. If one is bad then the others are likely not in great shape either. Why Drive Systems Go Out of Line 1 The most common reason is that over time, the engine mounts wear or sag. But the later is double the thickness in both width and cross-sectional area, with a substantially wider base. So, even though these mounts are small, they play a large role in the overall functionality of the heart of your vehicle. A bit of moisture is okay, for there are carrier solvents to help displace them. Use a good grade of stainless or the original screws and drill the hole smaller then major diameter, but not smaller then the minor diameter of the screw.
Wouldn't that be an artificial setting? So should the engine sit freely on all 4 mounts, with no pressure on the adjuster nut. Thanks in advance for your opinion! Remember to observe the witness marks to return the coupling halves to their original orientation. A v-drive flange take-off is used to couple the upper shaft of the v-drive to the torque tube. We think that with regard to your money, it's quite hard to beat the value provided on eBay. For all around use, the three-blade conventional-type propeller is generally used.
