I also made a thin shim of the appropriate diameter to place under the diaphragm retaining circlip to take up any excess play in the plate stack.Yes, the diaphragm spring wants to be pretty much flat, not dished in much, they do different thickness pressure plates to help with this but I too have an extra plain plate in.
If you go back to post #460 there are 3 links that have information and drawings of the lever. You need this one.... part number 04-0029 In my case both the pre Commando and Commando levers had two holes.Hello cyborg,
I have a similar problem with my Norton box. Do you have a sketch of the new lever that you can email to me?
Your help will be highly appreciated.
After my last post about clearance in there, I measured what is remaining after the addition of the seal and there is roughly .050" That means once the plates bed in and wear a total of .050" the pressure plate will come in contact with the seal (O-ring) carrier and the springs will no longer be able to exert any force on the clutch pack. I find this odd, because the seal , as you stated, only takes up .100". My clutch is already shimmed out farther than the stock Commando clutch because of the way that the splines are machined on the Newby clutch. It required more than the usual about of shims to fill the gap between the cupped locating washer and the hub. I could run it the way it is and keep an eye on it, but the adjuster (shown in the photo) isn't all the way through the plate yet and it should be... given that its an alloy plate. I could shorten the pushrod, but the stickup is only .148" and to get the adjuster so it uses all of the thread on the pressure plate, the rod would have to be shortened by .132" which gets the o-ring right at the bullet nose portion of the rod. So..... off with the clutch again and will add another shim or two.I just measured mine and the BCS seal will add .100" to the end of the mainshaft, so if you have 1/8" of rod stickout you are OK.
Ron,Being a very visual sort of person this sort of makes sense and I appreciate the heads up but the clutch is out of the bike now and I will have to put it together and stare at it for a while to really understand. Right now however we have sold the house with a one month closing date and I am boxing up all our earthly posessions and 40 years worth of interesting stuff I can't part with. The Comet is on hold for at least 6 weeks, but I can check that out when we get to our interim digs while waiting for a house to be built. I'll try to get time to buy a pre commando lever, just in case I need it, so thanks for the work done on that subject.
Maybe because it needs another tube , When used on a Comet, Although I have rode it without, But cracks showed in the F106.At the risk of insulting the “D” tribe... having them rise up, grab their pitchforks and head my way... that frame looks weird to me.
