Help needed: Clutch piston

Hi,

need your help. Wanted to replace the piston of the clutch cylinder today. I used air pressure to get the piston out. Then I think something was flying away.

Question: Is there a spring in the cylinder behind the piston?

Thanks, Joe

Yes there's a spring in there.

Thanks! Now I have a problem....

here is the pic from husky parts catalogs.which is the item you need.

From the drawing it doesn't look like it's listed as a separate part (although I can confirm that there's a spring in there). Perhaps someone here will have an old cylinder that they haven't got around to throwing away yet. Or mebbe you can buy one of those boxes of springs and find one that fits in the recess in the back of the piston, isn't so long that it goes coilbound when compressed into the recess and is strong enough to push the piston against it's retaining circlip when everything's buttoned up and filled with oil. Hope it works out.

Edit: hang on, I have my old slave piston in my shed somewhere, let me take a couple of measurements, there are plenty of places on the net that sell springs. I'm sure it'll be a bunch cheaper than $100 (or whatever) for a whole new cylinder.

The spring is back of part 23 but not listet. Maybe it is oming with the pistion or the complete cylinder.

Will call my dealer tomorrow morning.

EDIT: Will try KTM spare part #54832069000. Maybe it's near the same size.

clutch piston spring length

Hi folks,

does anyone know how long is the orig. Husky spring from the clutch piston?

Got the KTM part today. It is approx. 13mm long.

Thanks, Joe

Clutch Slave Assembly Spring ('04 TE450)

Unfortunately I've got mine apart right now. The inner edge to the housing that faces toward the engine is jagged on my bike with small pieces of metal where the clutch rod runs. So I can tell you the size of my spring on my 04 TE450....not sure if it's the same size as your bike. My spring looks about 18mm or almost 11/16th.
I bought the slave assembly today from Motoxotica but now have to figure out how to bleed the system. Anyone have suggestions?

I bought this for our clutches. http://www.rockymountainatv.com/pro...dlebars-Control&webCatId=12&prodFamilyId=8804

Thanks for the response. I watched the video and printed the instructions so I might be somewhat successful today. I might run over to Harbor Freight and see if they have something similar to the syringe bleed kit. I wish I would have seen that kit a couple of weeks ago. Now I'm in a rush before the rain hits. Perfect riding weather.

Thanks again for the help.

Thanks to everybody

Installed the KTM spring, 7602 piston, new clutch cable and bleeded the system. Used 2,5 fork oil. Thanks for the tip. Clutch is working fine.

Before the test ride I found my original spring (18mm) on top of my car winter tires. Didn't install it today, because clutch is working great. I think, the spring is not really necessary.

PS: 35 minutes without coolant in the race! Enigine is running fine. That's quality!
