Early K0 and K1 GL1000 Clutch differences

#1

Post by Streamliner »

I have an early GL1000 K1 ED with a clutch problem. It wont disengage when hot. I tried by replacing the clutch pack with EBC disks, but the problem prevailed.

For example from looking at the parts catalogue, they seem to have used two different styles of clutch discs, and I'm thinking that this might have to do with the problem, So if you look in the manual, for the K0 and K1
Disk A, 22201-371-000 up to serial no. 1020727
and then
Disk A, 22201-371-010 from serial no. 1020728 up until 2002383
then back to
Disk A, 22201-371-010 from serial no. 2002384

As my bike has serial no below 2002383, it seems I should have the parts ending with -010.

It would be great to know if this might have a bearing on my problem, or if just could go ahead and use the parts ending with -000, or if it is ok to mix and match, as they seemingly went back to the parts ending in -000 after 2002384?

Interesting. I have rebuilt several 1000 clutches and never knew there was a difference. As for not disengaging when hot my first thought would be improper adjustment of the throwout arm. that 3/4 turn is critical.

I have done some more research, it seems that the difference between the -000 and -010 is the outer diameter.

I ordered a clutch pack from CMS a while ago and got a buffer disc that had a too large diameter. Very confusing and I contacted them, they furnished me with a new one of the right size. I didnt know what to do with so I just stored it.
Now when I got the Disc A with the suffix -010, theyt also didnt fit. I compared it with the stray buffer disc and they were the same larger size. The inner splines are the same, but the outer diameter is larger. This makois it probable that there is a version of the early K0 and K1 clutch basket that has a larger diameter. Very interesting. I placed the -010 discs besides the -000 discs and took a photo, that is enclosed in this post.

So is there two different part numbers for the outer drum (basket) for the 1975 model? There is no record for that to be since the outer diameter did not change in later model year GL1000's. The Honda shop manual makes no mention of a difference. I check older posts and found this from John I(Old Fogey);
"You have 1100 plates 22201-463-000 or 84-85 1200 plates 22201MG9000. Both the same size and interchangeable.
And no, they won't fit" in a 1000.

So I am thinking your plates are for a later GL1100 or 1200.

Re my threads linked by Fred, after my experience with those EBC clutch discs (PayPal eventually forced the seller to accept the return) I would never willingly buy any of their products again.

From looking at the parts list there is one clutch basket for up to chassi no. 1020727, part no. 22100-371-000
Then another from clutch basket from chassi no. 1020728 to 2002383, part no. 22100-371 010
Then again, from chassi no. 2002384, they revert to part no 22100-371-000.

The clutch basket no 22100-371-010, seems to conforms via the serial nos to the clutch discs 22201-371-010, as well as the clutch basket 22100-371-000, conforms to the discs 22201-371-000.

Very confusing, has anyone ever seen a different clutch basket for the GL1000?

That second document is super helpful Cliff. Both the basket, pressure plate, plate B and lifter has interchange issues. Good to know and seems like a good one to post in shop talk.
