Clutch: Mini Clutch
Question: After replacing the springs and dog-bones, and seating the nut/bolt by turning counter-clockwise, the nut/bolt has very little tension after turning 4-5 complete turns clockwise. Is that normal?
Answer:
Todd,
When setting the springs you first turn all the way clockwise. With your thumb and forfinger turn counterclockwise until you feel the nut touch spring. Do this to all. Then put 1/2 turn more counterclockwise. They should be evenly set now. check engagement and adjust accordingly. You should never turn all the way counterclockwise. This can damage the spring.

Clutch: Wet Clutch
Question: I have problem with no axial clearance when using your spacer of 0.105 width. I see in one of your answers that you should not use a spacer when using "a bearing style drum". sorry for being stupid maybe but how do I know if I have a bearing style drum or not? I have a needle roller bearing on the drum does that make it a bearing style drum? If so I get it that I should not use a spacer but then my axial clearance is > your 0.020 spec, what to do?
Answer:
Hans,

You have a bearing driver. Bushing drivers do not have needle roller bearings. If your driver spins freely after you tighten the starter nut, the clutch will operate fine.

Question: For a project, I am calculating the clamping load at the wet 3 disk clutch, and I would need the coefficient of friction for the L&T 100-17 disks. Where can I find that?
Answer:

Question: I have the spacer that came with the clutch installed with tapered end facing towards the engine, it does not have any cracks, do I need a different spacer?
Answer:
I am not sure if you need a different spacer or not. I do not know what spacer you have or if the clutch is new or used. You might try putting the clutch on a different motor and see if you have the same issue. If you have the same issue and it is a new clutch, you can put it back into the box and send it to us including $10.00 to return it back to you and we will fix any manufacturing defect.



Clutch: Wet Clutch
Question: I have a 3 disc wet clutch and I am trying to install it on a kt100, my question is when I tighten the starter nut any tighter than hand tight the rear wheels will not spin freely while on the stand, if I loosen the starter but the wheels will then spin freely, am I doing something wrong? If I tighten the starter nut down and attempt to spin the rear wheels on the stand it almost seems as if it is trying to start the engine
Answer:
Logan,
The clutch spacer controls your end play. Check to make sure you have the correct spacer. Ours is .105 thick. If used clutch check to make sure center hub is not cracked. If using a bearing style drum make sure you are not using a spacer.
Thanks,
Jeff
