Bearing recovery

[ineedanother 1,729]

My apologies if this has been covered as I'm sure it has but I can't find it with a search. I'm replacing a case half on a hydro gear box and need to pull and re-use this inner axle bearing if possible. Advice?

Make a 90deg elbow bend in a flat screwdriver.  Wiggle that bend behind the bearing inner race, then use a long drift pin from the outside axle tube and tap on the screwdriver bend...gently ,,,moving around the circumference of the inner race.  It will move little by little.  Been there ---dun that.

I use this slide hammer from Harbor Freight with the hook tool.

 

 

Or a blind hole puller.

I have used a small wonderbar doing the same as Dave suggested, works well.

Great info. I think I could make any of those work but I like the thought of having better eyes on with the slide hammer. HF has it in stock locally if I need to pick one up. Thanks guys

If you don't wanna ruin a good screwdriver by bending over the end, just use the head of a carriage bolt instead.  The lip of the carriage bolt head will (usually) 'hook' onto the inner bearing race ...then use the long drift pin to GENTLY tap the bearing race around the perimeter edges...  it'll move little by little.

Decided to run out to HF at lunch and pick up a slide hammer set. I already have a driver set that I've found useful as well so I think I'm set  Thanks all for the input

I decided to piggyback off of this thread, rather than create another.

I'm going to be installing a new inner axle bearing. 

How difficult should it be to install? The old one came out without a terrible struggle.

I don't have access to a press, so I'm hoping I can simply use a driver and carefully tap it into place.

Place an axle shaft through the outer axle bearing and the new inner bearing to ensure proper alignment then lubricate the outer shell of the bearing, place a small piece of hardwood over the bearing and tap it into place. If the new bearing isn't going in easily you can put it in the freezer for a few hours to slightly shrink it.

I like that tip! Thanks!

Worked great!!!

Time to put things back together.

I have all the proper gaskets, but I've seen a lot of videos where they are using Permatex Ultra Black to seal up the transaxle case, rather than the thin paper gasket.

*Note: the reason for the initial teardown was the case leaking from a Permatex Blue seal job.

I've never been a fan of using sealants (when I have the correct gaskets). But if that's a better method, then I have no problem going that route.

Any gasket/sealant related advice from the experienced folks here?  I'll be reassembling the transaxle case as well as the hydro pump and motor.

Everything is clean, just waiting on my last gasket for the hydro motor (arriving today). The system will be using Dex/Merc if that has any bearing on your advice.

Keep sealer away from this hydro and every other hydro you may run across
