model 87 clutch

Post  banjo boy on Wed Jul 23, 2014 8:24 pm

Finally come to do engine. today I have removed the clutch plates they seem in good condition although had to free them so will clean up,now for the clutch basket again in good condition (will upload photo tomorrow).How much backward and forwards movement should there be there seems little play with up down movement where bearings are and the centre move nice a free,also the chain as a split link where as my manual says continual, the chain as a 1/2 whip taken measurment from bottom of chain then pushing up and taken measurment again from bottom of chain this seems a lot or is this normal that's all Smile

Make sure that the clutch withdraws evenly, many open like a garden gate as the springs get uneven with time. I renewed mine by getting a new set from Villiers Services, but they required a lot of modification - they had to be shortened and have some ground off the O/D to get the pressures right and even. Check the basket for notching and if notched carefully file down to a witness. You will then be rewarded with a super clutch. Bin the old chain and get a new endless one. Linked chains can fail at the link and smash up the whole lot.

Thanks Ted for your advice I will replace the chain and check out the springs.
Thanks again for your help.

I have ordered primary chain and crank seals are they easy to fit and best way to remove the old ones,the engine is on bench at the moment,is there any thing else worth doing at this stage.I have drained gear box oil my manual says SAE30 is this ok as I read some where to put SAE50 replaced all the fibre washers then hopefully put engine in frame very soon. Very Happy
