Pressing bearing off of pinion gear

[Jgranger01]

Before setting the preload on the yoke bearings do you have to push the bearings off of the pinion gear if you are not replacing the bearings?

If this is an Alpha1 the bearings slide off the gear and you just tighten the nut to torque.
If this is a Alpha ! GEN II you just need to loosen the bearing slightly. install and use rolling torque method

What is the preload now and why do feel the need to adjust it?

I don’t know the service history and I had gear oil in my bellows so I am just replacing the oil seal on the yolk. So I just didn’t know if the prior preload needed released by removing the bearing and reassembling or if I could just replace the seal and then torque in back down with a new washer? This is my first time doing this so I wanna make sure I am not missing any small steps

You don't have to remove them but you do need to 'loosen' them. Only needs them to move a few thou apart....

You don't need to disassemble the bearing pack completely, as stated you do need to "release" the current torqued state of the bearing set and upon reassembly use a dial lb/in torque wrench to set the preload to 3-7 lb/in.

If you hold the bearing pack in one hand and tap the back side of the gear with a hammer that should be enough to relieve the bearing set and have a loose starting point for reassembly. The process is outlined completely in the oem service manual. #6 for alpha one #14 for gen 2

Chris,

I watched your video on setting the preload and its very informative. I noticed that the dial wrench you were using was barely going up. I am looking all over online and i found one that goes from 0-150 in lbs. But the reviews are saying i cant use it to set 5 preload. i cant find any that move in smaller increments. What kind of wrench are you using.

This one from Precision Instruments is the one I used. It has gone up a bit in price since I bought one in 2016, everything has. Is a superior tool.

Could I get away with using the 0-150 in lb one? because it’s significantly cheaper. I realize it’s an inferior tool but it seems like it should get the job done.

If you can differentiate between 5in-lb and 10in-lb, and it's calibration is good right down to the bottom, and you're confident in it, yeah sure...

You can do what you like but that wrench most likely will not read accurately enough for the 3-7 lb/in rolling torque required

Thanks for the input guys. Always appreciated. I’m gonna try that 150 in/lb one and if doesn’t work it’s from Amazon I can just send it back and I will take it to the local boat shop and pay them to torque it.

Problem is you won't know if you have a problem until you explode your drive. Wonder how accurate a small scale beam unit would be

Don't waste your time. Creeping up on 5 in pounds will not be doable with a gauge made to work up to 150.
