Initially, the clutch had what were probably 2, .030 clutch disc spacers, not the thinnest & not the most rigid.
But these 2 spacers alone gave way too much free play at the case lever. I ended up putting 2 .050 spacers and an additional 2 .030 spacers, for a total of .22 in spacers. In fact all the spare spacers I had. Giving what measured out to approximately 3/32” in free play on the case lever.
I can put the tranny in neutral. But just pulling in the clutch lever without raising the rpm will cause the motor to stall. Rev-ing the motor allows me to pull the clutch in, but depressing the shift lever from neutral to 1st gear causes an immediate stall. There is no feathering. The motor stalls with the clutch lever fully pulled in and shifting down to first.
Now, assuming this clutch was still in functioning condition, the clutch showed reasonable material left on the discs, I have not used this many spacers before. Does it need more? It would seem this is not a low mileage clutch because there were only .060 in spacers before disassembly of the motor. Additionally there’s a .010 piston in the motor so it was run long enough to wear out a piston.
I remember Matt mentioning he found a Dirt Squirt with what he thought was still a brand new clutch containing .26 in spacers behind the clutch disc.
So I still don’t get it. This put enough spacers until you get 3/32” of free play isn’t seeming to work for me.
HELP!!! I’m tired of a couple of clutches being my nemesis! Out of 7 bikes, I’ve only had 2 clutches behave non-productively. These others were pulled and put back in with the same spacers with which were on board and nice as you please, the clutches worked. 2-3 spacers was what they all had in them and the Speedo’s all said they had under 1500 miles on them.
Yet, the clutch in the Wombat Combat was shot. I blue printed per the Resonator article, installed the correct number of plates & discs for a Combat Wombat motor, added a few spacers until reaching 3/32” free play and THIS Combat wombat clutch works just fine!!! The clutch was loose in a box, not on the motor with any spacers & there were no spacers in the motor box. Motor was completely disassembled. And aside from not rebuilding and blue printing this Combat Wombat clutch, but setting the free play the identical way, it won’t work. Period.
Don’t shoot me, I just don’t get it. And yes, I am carefully measuring the free play. I move the lever to its bottom position and I measure up 3/32” and put a pencil mark on the case and add spacers until the lever moves from the bottom position to the pencil mark and stops. The roller bearing is in place inside the case. Free play testing done with gasket between cover and case. Where am I going wrong?
