Have you thought about woodruff key in flywheel, its happened before,

Hi,TrialsRfun can you give me the details for brake drum reline please, mine need doing before I put it back together, Cheers, Myson

Great post re removing bearings Martin, wife wouldnt notice smell the way she cooks!!. Will still have the pizza though, Myson

Hi, thanks for the reply, I believe tht you can use a modified seal retainer to do this but this one has the bearings located inside the original casting, Dont know if this is possible on original M80 case. Myson

Hi, I have just split the cranks on my M80 engine and have found it has 3 main bearings. I was sure that it was only later models that had this feature. I also want to remove the two gearbox bearings that are located in blind holes, what is the best/easiest method? Cheers, Myson

Cheers Woody. Will order from Pyramid

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,

Will have a look in books tomorrow, failing that try Bultaco UK they are usually spot on. You could also take hub to bearing factor and see what they can sort out, Myson

If thats the case just go to your nearest Force 7 bearing factor, cheap and very helpful for any bearings, I got new mains for mine for about

Thanks for the reply, the bearings feel fine I ws just thinking of doing the job while I had the cranks split, may save a job later on, I was going to have a new big end bearing fitted to original con rod if possible, Myson

Hi, I am slowly progressing with my M80 rebuild and I am splitting cranks to replace gearbox shortly. I am considering having the crank rebuilt with new bearings but most kits include a new conrod. This adds a lot to the cost when budget is limited! Is it feasable to rebuild using the original con rod with new bearings or is there a good reason for replacing everything? Also, can any one recommend a good engine guy in Newcastle/Durham area to carry out the rebuild? Cheers, Myson

Thanks guys, once again first class help with problems, Cheers Colin

Hi Sparks, thanks for the help. Do you have details of company in US that supplied the keys please, Regards, Colin
