February 15, 201016 yr does any know the code/numbers for a set of taper roller bearings as i dont want to pay bultaco uk prices when i can get them cheaper in a local bearing shop
February 16, 201016 yr You probably wont find them in a bearing stockist. But you could try. size required are 45x25x12 Closest you will find easily are 47x25x15 (32005x) Which can be modified to fit, but is the work of hard turning or grinding the o/d down worth it? The link quoted by Keith above is about the cheapest out there I believe. Wayne..... Edited February 16, 201016 yr by wayne_weedon
January 6, 201115 yr I purchased a set of taper bearings from Pyramid and they fit perfectly, they are cheaper than the originals from BultacoUK as well. Give them a ring with the size you want and they send them out straight away. I didn't have to machine anything down, they are a straight replacement. You will need access to a press or get your local tool shop to do the work for you. My M159 took size 45x25x12 and they were available off the shelf.
January 10, 201115 yr Is the M80 the same size as stated (45x25x12) or is there a diferrence between models? I have heard that head nuts may also need modification, any idea? Cheers,
January 12, 201115 yr I as told that I would need to machine down parts to make the taper bearings fit, but this is not the case, the pyramid bearings are a direct replacement. Not sure if all models use the same size, I'll leave that to others. Good luck
January 12, 201115 yr They all use the same size (well, from model 49 definitely, I've never had a model 10 or 27) The Pyramid bearings are a straight fit as they are the correct size. You only have to machine the alloy head top nut if you use the Sammy Miller kit as the bearings are thicker than 12mm.
January 13, 201115 yr Hi, Got mine from ebay from this guy Member ID p-k-n ( Feedback score of 46123) .was 20 quid. didnt need a press to push the bearing on. stick it on yer wifes cooker, if its gas and warm it up. i used a piece of tube cut to the correct length and slipped it over the yoke stem, then wound the steel head nut on untill it pushed the bearing into place.dont forget the original bottom cap needs to go on first. i did *@** Miles better than the original bearings. Hope it helps. Tom, PS it was 20 quid for the complete set top and bottom Edited January 13, 201115 yr by tomtom385
