la bala Posted August 19, 2019 Report Share Posted August 19, 2019 Need some advice on Fairey Overdrive. When I had my gearbox reconditioned some time ago I left the overdrive off. Something to do on a wet day. It had always had a bit of a whine so today i whipped the front cover off. Well the the top of the ball bearing cage just lifted off and the remainder is just mangled pieces. My question is can the bearing be pulled straight off the shaft, I have removed the large circlip but think it will have to be pulled, The next problem will be making a puller, there is not much room.

ditchman Posted August 19, 2019 Report Share Posted August 19, 2019 if you are frite of taking it apart........spot weld 2 threaded rods onto the inner race then drill out a bar (3 holes)...drop the bar onto the threaded rod ....couple of nuts....srew/bolt in the middle hole and draw off.......... do it with the same 2nd bearing beneath it......

la bala Posted August 21, 2019 Author Report Share Posted August 21, 2019 Right big ball bearing, big circlip. You would think remove big circlip followed by bearing, you may have to give it a little tug. Ok cut three pieces of 10mm threaded bar, tack weld to inner race at 120 degrees, we now have bottom half of three legged puller, add plate to top, tighten nuts bit at a time simple. Not so, soon as it gets some torque its pulling lumps of hard facing of the bearing race. After rewelding a few times I was getting a bit miffed. Right I will weld the puller bars to the inner and outer race and pull the lot out together. Yer ok, after another hour of tightening nuts and rewelding I had had enough. In a couple of hours I had pulled it about 3mm. I am sure I am missing something Quote Link to comment Share on other sites More sharing options...

la bala Posted August 22, 2019 Author Report Share Posted August 22, 2019 (edited) I think there lies the problem, having to retack so many times to disimular metal, I was expanding the outer race. Edited August 22, 2019 by la bala Quote Link to comment Share on other sites More sharing options...

figgy Posted August 22, 2019 Report Share Posted August 22, 2019 Could always warm the lot in the oven and put ice water on the bearing, then pull the race out. Quote Link to comment Share on other sites More sharing options...

la bala Posted August 22, 2019 Author Report Share Posted August 22, 2019 Well today before causing any heat by welding, i found a little slide hammer which i could just fiddle down the outer bearing race, Bingo the outer race is started to move, I am busy watching it coming closer to the top of the housing and oh dear, I am pulling the whole ruddy innards out. Well at least the outer race has cleared the casing but not the way i wanted it too. I decided to make another puller to hopefully get it off. No its not having any of it, just bending the puller. My last hope now is a fine cutting wheel in the grinder, try and get a few cuts in the race and fracture it out. I just dont know why its not moving, I am still doubting myself.

figgy Posted August 22, 2019 Report Share Posted August 22, 2019 When you replace the bearing put them in the freezer overnight. They should slip in easier. Quote Link to comment Share on other sites More sharing options...
