outdrive stuck

[Scott06]

Not making much progress with a hammer. Can I cut this off or grind it off?View attachment 407905

Yes you can cut it off just take care on the inner race not to cut into drive shaft

Can use a grinder but note steel in bearings is hardened
As Lou mentioned heat will help but need a lot of heat fast

Yep thought of the grinder but gotta be careful!

Using the grinder cut off the outer race and strip the bearing of its balls and cage so the only thing left on the shaft is the inner race. Clean off all the grease. Set the shaft splines in a vise protecting the splines. Have the bottom of the shaft sitting on top of the vise’s slide. Get yourself a punch and determine the best arrangement to impact the back end (that is facing up) of the inner race on either side of the U Joint with the punch as vertical as possible. Then use a torch to heat that inner race as uniformly as you can pointing the flame away from the U Joint. After it heats up if it does not fall off smack it using that hammer and punch. One side then the other and not heavy blows. And do not spend a long time heating it up as there will be heat transfer fm the race to the shaft and both will expand.

sounds good
and as much as it can be a pain, removing that outdrive at the end of each season, can help you avoid the pain, of this!
my gimble bearing was last replaced 21 years ago
just checked the bellows I replaced 9 years ago and it looks great
the ujoints, are original, 37 years old with grease fittings lol.

Be much easier with that yoke removed. I'd probably try supporting the aft end of the bearing vertically in a vice and hammering the yoke from above with a 2x4 on top. Not sure how that would treat the splines though.

If you were changing the u joints yes take the yoke off put it in a $100 harbor freight press and it will come off with out damaging anything

The press is well worth the investment

If going that route and don’t want the press can take it to local garage and for $20 they’ll probably do it

Wrap the splines in some foam or tape them up heavily to protect them…

If the gimbal is frozen to the shaft probably not a bad idea to do the ujoints anyway. I really need to buy a press. I just got a drill press, and it's like magic. I'm so damn short on storage space though...

Yeah I put mine on wheels but fervently stub my toes on it. I bought mine for rebuilding the suspension and changing rear gears on my gto. Was right there when rebuilding jet pump on the seadoo and doing seals and bearings on my outdrive. For all the work you do it’s worth it.

That’s the point with a press you wont damage the splines unless you are chit faced…a bar on either side of the bearing or use bearing separator , press down on the center of the shaft with a pice of round stock or socket
