Hi, lt looks like master cylinder partial stroke, and/or control plate failure. to eliminate, try to adjust stroke free play by screwing in the adjusting screw on lever. also notice if lever travels all the way outwards when released. Possible reasons to failure may be: dirt, piston O ring weare, spring failure (rare), or cylinder bore weare ( ovalization). measure the control plate springs as well. should be 40mm. long, check inner core of control plate - tends to breake. good luck! |

Hi, I bought the original clutch kit from / (it`s about GBP 88 + shipping) did`nt need springs, but was told it`s about GBP 3-4 each. also check [url]http://www.ferracci.com/store/cart.php?m=product_detail&p=224 it looks very promissing . [/url] |

Thnaks paso750 that's the thread. I have a photo that I'll try and add to the thread when I work out how but I'll add a link here as the is the most recent clutch topic and it might be handy to refresh everyone. I dug this out of an old performance bike magazine I was reading that was around from the early 90's here in Australia. The bike I think is a Pantah of some description that appears to have been built for racing by Peter Smith of Epicycle. Peter was involved in the factory superbike race team here in the early 90's when they started with the 851/888 and he and the team were very successful in developing the bikes on a limited budget. What's of interest to me however is (a) it looks like the bike was converted to cable clutch operation and more importantly (b) it looks like he manufactured a new pressure plate design that also looks like it is aluminium in construction. That would be somethign handy to get into production again me thinks. Thoughts????? http://members.optusnet.com.au/~gavnkym/gallery.html My other thought on the slave piston/bearing design was could a new piston be made that has say a tapered needle roller bearing seated in the bottom to take the rotational and thrust loads with a longer bodied pin coming up to the correct height. Could this then be sealed with one of those oil dust seals commonly used in the back of front hubs on cars and in the front wheel of our bikes (my 17" version at least). It seems their design is to retain oil/grease on one side and prevent dust/dirt ingress from the other. Lust not sure how effective they would be with the fine abrasive dust or heat from the clutch????? |
