Ok, I have a cb360 that may need a clutch. I have not yet looked far enough into this yet, and am just feeling around what I can do about this.

I'de like to replace the clutch myself, as the cb360 seems very simple. I've tinkered with carbs before and basic mechanical procedures on cars and bikes, but this by far would be the biggest undertaking. So is it possible for me to do this with simple tools, or am I insane for even thinking I can do it.

If someone could explain the procedure breifly it'd be greatly appreciated. Please pardon my ignorance and aprehension, but whenever someone talks about replacing a clutch on anything they make it seem like a nightmare. So please enlighten me.

also any idea what parts i will need and where to get them would be nice too... thanks.

Dump the oil, take off the sidecover, take out old plates, put in new, fill with oil, adjust per manual, one hour if you stroke it

I put a clutch in my 88 FZ yesterday at work. Even did the old mx trick of leaning it over far enough to the left that I didn't have to dump the oil.

What makes you think it needs a clutch?

 

[bissinger]

no pressure in the lever. When lever pulled all the way in, and put into gear it takes off, makes for an exciting time.

the Previous owner said that "the cable just needs to be adjusted". but other than that the bike is pretty solid and i got it for $600, with the carbs rebuilt so, I didn't really mind. I may have found a parts bike, would it be possible to swap out the clutch from that?

if it takes off then you do not need a clutch pack you need to adjust it. You have too much free play somewhere. But I'm too busy at the moment to go through typing the procedure. Someone else?

Brian,
Replacing the clutch is a piece of cake. Drain the oil and pull the right engine cover off. If it still has the Phillips screws, get an impact driver before you waste your time and the screw heads. Take the time to give each screw head a smack with a flat faced punch. That will help break loose any corrosion on the threads and reset buggered up Phillips heads. Now use the proper fitting impact bit and the case screws will come right out. Pull off the kick starter and pull off the cover. The clutch is held together with the 4 10mm head bolts. Remove them and the springs and pull out the plates. I sand the steel plates with 100 grit sand paper on an orbital sander. Clean them off good with brake cleaner and reassemble. Some people like to soak the new fiber plates in engine oil prior to assembly. I don't feel strongly about it one way or the other. You may need a new clutch cover gasket, but unless it is really torn up a light coating of Permatex Form-a-gasket will usually take care of it. Don't use silicone sealant. The part # for EBC clutch plates is 381922 - $62.99 and the springs are 382015 - $9.99 from Dennis Kirk,www.denniskirk.com.

wow thanks a lot guys, all of your posts are helping me better understand this situation as i know nothing about transmissions. Ill try adjusting the clutch cable first, and if that doesnt work it's onto the clutch itself.

Imslow when you get a chance would you be able to write that up, Im not in a rush though so take your time... thanks

Find the manual online, for proper clutch adjustment. I'm too lazy (and buzzed) to give you a link.

 

[ROSKO]

follow the adjustment procedure in the manual here:
ftp://ftp.manuals.homeftp.net/Manua...250-CB360-CL360-CJ250T-CJ360T Shop Manual.pdf

and just so you have an idea, the clutch looks like this:

rosko thanks but i went to download that pdf and gave up after about 10 minutes it's probably there but whew.

That is what you get for using a Commodore 64, with optional mag-tape drive.

scott,
it's an ftp site, super-slow. just hit it at night and let it take it's time.

 

[bissinger]

so i tried adjusting hte bolt on top of the case, and it didnt do anything clutch still wont engage any ideas or should i be taking this hting to someone that knows what they're doing

If it were mine I would pull the sidecover off and inspect the clutch stack. If everything's okeedokee worst case you're out a gasket.

I have seen clutches stick together from sitting. It is possible that is what you have and someone has stretched the cable trying to force it. Although usually they break.

But anyhoo, if you've exhausted the external adjustment options, time to pull the cover. If you can change oil you can do the clutch yourself.

Wish you were closer I'd sell you a 360 I have. The only things I know for sure about is that the motor's not stuck and it doesn't float.

 

[bissinger]

yeah, the cable moves fine, but above when someone said it wasn't the clutch if there was no pressure in the lever. Im pretty confused I just need to get someone to look at the bike and tell me what the deal is. I have no problem changing the clutch, if i buy it will it just come in a stack and i just pop it in?

 

[midge]

i had stuck clutch plates on a bultaco that had sat for some time, i had to pry them apart with a screw driver, took them out cleaned them oiled them and put them back and all was well.
i would check the plates to see if there stuck together, then find and adjust the slack adjuster, not the cable but the [ clutch lifter adjusting screw]

its right under the brass grease nipple,

first you may want to take off the rear cover disassemble the lifter, clean it and grease it, see items 6 through 13 don't lose the ball # 21

 

[bissinger]

if the plates were stuck together, then would the lever still have pressure?

you guys have helped a ton thank you i appreciate it

 

[midge]

yes,
when you pull the lever you are trying to separate the plates, if they are stuck together there will be lots of lever pressure, like pushing against the wall you push it does not move- equals pressure,
you may find some of the plates are free and some are stuck, they all need to be free,
if you have 8 friction disks and 8 plates and you only have one free then when you pull the lever half the pack is moving against the springs, but as some are glued together, when you put it in gear even with the lever pulled in power is being transmitted through the stuck sets, and the bike will try to take off, go ahead and pop the cover off the hardest part is going to be getting the screws out of the side cover, after that you will find it pretty easy,
get a book/ manual and an impact screw driver, its not as bad as you may be thinking

 

[kenessex]

Bissinger,
If you don't get any lever and have adjusted tthe cable as best as you can, then the problem is in the adjuster in the left cover that Midge posted. I would suspect that the adjuster is turned so far that the triangular bearing piece Patr #10is out of its ramps, or even more likely, the ball part #21 is not there. The PO probably lost it and didn't notice it was missing after reassembly and sold the bike. This is not a clutch plate sticking situation. When that happens you pull the clutch lever and compress the springs nd the clutch stays engaged. In that case, clutch pull feels normal.

So pull the left cover, Check that part 21 is there. then reassemble and adjust the clutch according to the manual.

[midge]

ken is he saying the lever is slack or the lever has pressure im not clear on that from his postings?
if the lever is slack, do what ken said start on the right side with the lifter slack ajustment.
if the lever has pressure than check the adjustment on the right and look at you plates too

 

[bissinger]

sorry about the lack of clarity. there is NO pressure in the clutch lever. Ill take it apart probably on tuesday night, and post some pics. If I recall correctly I dont think that little ball is in there. what does it do?

again, you guys are really helping, and saving me money and it's appreciated.
