    Anyone have a method of removing the rear cover bearings ? some time back while rebuilding a 201 halibrand I tried heat/chilling/reheating/ penetrant etc. with no results, ended up getting a new cover but would like to use the script cover at some point. Thanks, Ron

    I put them in the oven and heat them up and they just fall out.

    Did try that some time back however I've read anything above 350 f may cause warping true or not ???

    I want to say I heated them to 350 degrees, with the even heat in an oven shouldn't cause any problems.

    They tended to fall out when changing gears on a hot rear end-someone may have lock tighted them in--a little heat and a slide hammer made for removing seals may work

    I use a small toaster oven for this, at 300 degrees. If you block the cover up, face down, the bearings should fall out. If not, have a welder's glove handy, remove the part from the oven, an slap it down on a 4x4, and they should fall out. IMG_6544.JPG

    Thanks, need to see how I'm able to grab on to the bearing to put some prying leverage on it, don't have it readily available to ponder it again...currently stepping through a 11 bolt Frankland rebuild with a similar situation & it happens to be the deep cover & perhaps even more challenging

    If all else fails, cut the inner race out, remove the balls and cage, weld a bead around the inside of the outer race. Works every time.

    Thanks Marty, I always enjoy your posts & I did early on exactly as you suggested even giving it a couple hammer raps, I'll need to give it another whirl for a longer bake. Might be in order to pick up a toaster oven at the 2nd hand store & stay clear of my wife's new oven.

    Yeah, thought about breaking it out & tacking on as well

    I use an old gas oven that came in the basement of the house I bought. You need to put the part in and let the oven get to 300 or so then remove your part. If you take it out to early it won't be to temp yet.

    I followed Winter's directions. Place the cover bearing side down, on spacers taller than the bearings, then gently heat
    the cover with a propane torch (for plumbing). The bearings will simply fall out.
    If you heat the entire cover and bearings in an oven, both will expand and defeat the purpose.

    Expansion rate is different between the two dissimilar metals.

    Usually the oven heat works just fine. But, I recently had two that just wouldn't budge. I limit the heat to 350*.

    I had a Snap-on blind hole bearing puller but not the proper collet. I borrowed one and then ordered my own which worked just fine.
    I can post pics and part numbers tomorrow.
