AlanG Posted March 10, 2017 Report Share Posted March 10, 2017 I'm struggling to remove the three shell type needle roller bearings from the input and counter shaft. What's the best way of doing it? Alan. Quote Link to post Share on other sites
Rob Salisbury Posted March 13, 2017 Report Share Posted March 13, 2017 Carefully applied brute force and a sacrificial very sharp wood chisel worked for me Alan, not pretty, but it get's the job done!! Cheers Rob Quote Link to post Share on other sites

AlanT Posted March 14, 2017 Report Share Posted March 14, 2017 If you are lucky there will be a gap about 1/16in wide behind the bearing cage at the bottom of the hole. Somebody like me with a lathe can make a "top-hat" section with a threaded hole in it. Then slice this in half and jiggle in behind the bearing. When you put a bolt back in the thread the two halves will "jump-out" and grab the bearing. Now you have a home-made puller. They are not very tight, just awkward. If there is no gap, because someone pushed it in too far, then you jack the top-hat in between the rollers and cage and pray. This will not be the last little tool you will need to make to get a gbox to bits and back together without a lot of brute force and damage. Likewise the OD. Quote Link to post Share on other sites
AlanG Posted March 14, 2017 Author Report Share Posted March 14, 2017 Thanks for the replies folks. I eventually used a dremel and very carefully ground the outer shell until it was paper thin and then split it with a chisel. The grinding has to be done very carefully so as not to damage the shafts. I would not recommend this method and next time would make, borrow or steal a puller. Alan.
