: removing bearings ?
morpheus 06-20-2002, 07:37 AM Hey, i'm trying to remove some bearings, two off of a D44 carrier and another off a Toyota tcase input shaft. and i can't get any kind of puller/seperator behind the bearing to even get started pulling it off. i've searched and didn't really find any answers though several people have asked the same sort of question ...
can anybody help me out ?

mine was on a different application, but maybe it would work for you too?
i welded a 1/2" nut to a giant washer (that overlapped the inner race diameter a tiny bit) then spot welded the washer to the old bearing. screw in a length of threaded rod, and enough purchase is now available to lever/yank the bearing out.
alternatively, you could tack weld any old piece of steel to the bearing and maybe use a slide hammer (ie the kind with the "screw" type end that is used for pulling body dents out)
good luck!:beer: :)
morpheus 06-20-2002, 08:01 AM interesting technique ... but these are good bearings that i'm wanting to reuse. the tcase bearing alone costs over $50 ...

For bearings that I can't get behind the races, I've had no problems pulling the bearing with the splitter behind the "cage" that holds the individual bearings.

Oxjockey 06-20-2002, 08:29 AM Have you tried against the cages? I don't think you're going to have a choice. The carriers are supposed to be notched for a puller, but I've seen plenty that weren't :mad: We wound up using a combination of puller, splitter, pusher/puller, and even the press for the more stubborn ones...

CarTools.com (http://www.cartools.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=001&Product_Code=pubpOTC1123) is a little cheaper than the above, but this is the one I have. And the appropriate pusher/puller.

ahhhh. the old re-use the bearing trick.
hmmmm. i have an old gasket scraper (quite honkin' big) that has a fairly large/thick blade end. i ground off the sides of the scraper part (in effect just narrowing the blade) and bent the end with a torch almost 90*.
the scraper end is quite sturdy, and if there's room, you can wedge it inside and behind the bearing, tap the handle with a baby sledge and again, lever out the bearing.
you could do the same thing with a giant flat blade screw driver, but the end wouldn't be as wide as the modified scraper one.
i have had to be inventive over the years, owning weird motorcycles that even the factory mechs didn't have the "special" tool for every single model/year design change.:(
but all my uhh....devices worked just dandy.:D

if i pull it off by the cage will i ruin it ?? I've got a puller like that but had not used it on the cage for fear of tearing it up ...

Oxjockey 06-20-2002, 09:48 AM It depends on how tight it's on there. You may wreck it, but if you have to get it off, you have to get it off. Try UZI's suggestion first...but be careful not to nick the bearing or the carrier.

It's the blue and red thing in the right of the picture in the middle of the page. Removes bearings without screwing them up. Might not be the best choice for one time use though. I think it's around $300-$400 if I remember right.
Those types of tools also grab a hold of the retainer (cage). My buddy managed to snag a production tool when Dana cleared out their Ft. Wayne location of any axle production.
Using the "grab the retainer" method, I've never damaged a bearing, pinion or carrier (d30, 35, 44).
