What type of clutch is in my 83 xj1100

I know it is a wet clutch but are there different types of wet clutches?

Sorry, just trying to learn. I have to fix a 2nd gear problem and my buddy asked me what type of clutch is in it (hydrolic, spring, i don't know)

 

Spring

 

My buddy recommended getting a kit to convert the spring clutch to a conventional clutch. He did it to his fj1100.

Any thoughts...

 

It's a spring tensioned multiplate wet clutch, mechanically actuated.

Second gear problems on the bigger XJs are not uncommon; a 100% properly operating and adjusted clutch can minimize the issue but if the tranny is worn from "banging second" then it's case splitting time.

The primary chain tensioner can also disintegrate and drop chunks into the shifter drum causing difficutlies shifting, but if it's jumping out of second then it's tranny fixin' time.

 

Define "conventional."

Even a "conventional" automotive clutch has a spring, one big 'diaphragm' spring (like my Norton) rather than the 5 or 6 our bikes have. But it's still a spring.

A car clutch has one big plate too, and it's dry. But also too big in diameter to be practical on a bike; and quite frankly, the diaphragm spring in the Nort is a bloody PIA compared to the 5 springs in my XJ's clutches.

Whatchoo talkin' bout, Willis?

 

I have never seen the inside of my engine but I beleive this is a conventional clutch. The clutch in the fj1100 is different according to my buddy so all is good.

Wow, imagine how much I am about to learn.

Thanks...

 

My 1100 has to come apart too. Just have not gotten around to that one yet. It has the pop out of gear when you gas it. Let us know how yours works out. Check out the 2nd gear fix on the XS1100 site.

Good Luck

Okay, my buddy showed me what he was talking about on his fj1100. Instead of 5 or 6 springs it has a concave (or convexed I am never sure which is which) disk to apply pressure to the clutch. He replaced this with a kit to switch it to the 6 spring type. Just easier to find parts and less expensive to replace the springs.

I am learning so much.

MN-Maxims, I will keep this thread going as I do my work. Yesterday I pulled the engine out of the bike but ran into a problem mounting it on my buddies engine stand. Today I will get a longer mount and finish that off. Then I can use the engine stand to flip the engine over and take a lookee inside.

Turns out my brakes are grabbing as well. Will probably do a caliper and cylinder rebuild later.


Well I gotta go.

Later...

 

That "convexed" plate is a diaphragm spring, more like a car clutch. It's what my Norton has too, and it is indeed a pain compared to the multi- coil spring clutches in the XJs.

 

Okay so the week end is over and I have my gear pulled out. It is pretty worn but since it wasn't actually poping out of second (just hoping around) I am assuming it is safe to drumel to fix. I checked out the other dogs and they looked new.

Does anyone know the minimum width for a dog before you should replace the whole gear?

I got the instructions for how to do this at the following url on the XS11 site:

Good luck to all who are trying it. The guy in the article leaves his engine in the bike and flips the bike. I actually took my engine out and borrowed my buddies engine stand and mounted it on there. Just made it easy to move around the engine to get a better angle on some things.
