Very nice vid. What did you do with the nagged clutch hub? Sand it down or replace it completely?

@Wizbang2u

Hi Wizbang my stator wires are fairly close to the chain but there is no contact but there is a slight contact mark on the small oil feed pipe.

Ah yes them stud :-D gutted to say the least lol turned out ok though.

Question I have 72 750 Triumph...which clutch was stuck....I freed and cleaned the steel plates...it worked fine...then I rode the bike for about 30 min, which was the longest and hottest the bike sat over night and then next morning the clutch was stuck again.So i have a new clutch coming from notherneagle.ca

My question is....1) was the old clutch just done and need to be replaced?

2) with the new clutch coming....should I soak over nt in oil....just install dry?

Thanks....super helpful vid

Hi thank you! for the old plates try boiling them for 1/2 an hour get them grease free.

The clutch plates should be assembled dry

the main reason for them sticking together. Stuck from age ? Fill case with auto. trans fluid, and let sit for a couple days. Rock the bike , while holding the clutch lever in, and see if you can break them loose. This will greatly aid in disassembly. Where did I learn this stuff ? Working for Sid Biberman , of Vincent fame, for 17 years, and riding these bikes everyday for about 30 years.

I also have gotten the Norton hyd. chain tensioner to work properly by careful cleaning out the entire clutch case, sealing the little scupper plate on to the tensioner body, and install a fine piece of metal screen in the catch area in the top of the tensioner body. This will keep any garbage out of the check valve and allow it to work properly. Assemble a wet clutch wet in the same oil you would use during operation. Old bonded plates will collect oil by products such as "asphaltine", and is

Take caution to ensure that the altenator. Mounting stud nuts are tight, on Tri,, Nort & BSA. If they come loose, the stator will touch the rotor and you'll get a nice surprise. Always check them even when doing non related clutch or pri. chain work. On the all metal Norton clutch, clean them good along with entire prim. drive area, and when you put it back together, use 2-stroke oil, non synthetic, and the performance will surprise you. Also sand them with 80-100 grit, and a dual action sdr.

ayup, i assume the free play in your clutch sprocket is nothing to worry about. I have just put my 500's clutch together and I have the same free play.. got me worried.

Thanks for the vids, very helpful
