ebinmaine 67,265 #1 Posted February 20, 2020 I need to change one of the large ball bearing carrier bearings in a gear drive 8 speed. Any dos or don'ts? Tips or tricks? Special tools? Thanks in advance. Share this post Link to post Share on other sites
pfrederi 17,662 #2 Posted February 20, 2020 Assume you want to replace it with a new one. Drive the needle bearing out Then I use a long brass drift pin and drive the 1533 in. 1 Share this post Link to post Share on other sites

Reason being is I have an 8-speed that had a broken case from being dropped off a truck. if that has good bearings I'll try to take one of them out of that.

My method may be too hard on the bearing is you want to reuse it. I only remove them if they are bad. Might ask Steveasaurus 1 Share this post Link to post Share on other sites

stevasaurus 22,706 #8 Posted February 20, 2020 There is almost nothing worse, then trying to get a #1533 out of the case without hurting it. In this case, it is going to be a piece of cake. Open up the broken case transmission, take the broken half and a 4" grinder...and cut the case away from the bearing. Boom-sha-ka-la-ka!! The thing about these bearings is the retainer keeping the bearing together is very thin, spring like metal. Obviously, a bearing puller is the best way to go. The brass punch is the next best, but I would also try to heat the casting around the bearing. If you use the punch method, make sure you are just tapping and attack the bearing with one tap while working around the bearing in thirds. I have had success with an air chisel and sometimes they just pop out. 1 1 Share this post Link to post Share on other sites

Just make sure you keep things greased and they work pretty well. I got them for doing a three piece since I couldn't find Steve's ground down carriage bolt I made for bearing puller. I think I might have paid less than 40 off flea bay... search blind hole bearing puller... https://www.amazon.com/Bearing-Puller-Internal-Extractor-Remove/dp/B017XDLDDY/ref=sr_1_5?crid=3KK9U86S0YPRL&keywords=blind+hole+bearing+puller&qid=1582220646&sprefix=blind+hole+bearing%2Caps%2C185&sr=8-5 2 Share this post Link to post Share on other sites
oldlineman 1,481 #10 Posted February 20, 2020 I would say a little heat on the case would be very beneficial. 1 Share this post Link to post Share on other sites

squonk 41,020 #12 Posted February 21, 2020 (edited) Harbor Fright ( yes I spell it that way ) has a blind hole bearing puller set with many sizes. They also have an axle bearing puller set that may yank it out. Edited February 21, 2020 by squonk 1 Share this post Link to post Share on other sites
