Does anyone have a Max IV T20 handy that could verify the total thickness of the two washers used to space the driven clutch. I?m having trouble reading my notes but think it?s about .310? total for the two washers. I know a lot of people have asked why those spacers are on the input shaft. I was told many years ago that the clutch moving face strikes the chain tensioner. Thanks
Mark, sorry none of my t20s have the washers, wonder of it was to make up the difference of the o ring chain.Originally Posted by msafi65

Joe Camel never does that.
Advice is free, it's the application that costs.
My Max IV (mostly stock) with original trans and engine location does not have any spacers with the Comet style driven clutch and there are no interference issues anywhere close to anything.
My Max IV (highly modified) with forward trans like the buffalo and Invance driven has a spacer because the moving face will come very close to the shifting linkage. It's 1/8" now but may need to be increased once I get it up to full RPM.
Washers may be required with an engine swap to get the clutches back into alignment. Primary clutch offset depends on how tight the belt is. Rule of thumb is to have the belt inboard edge just touch the inboard sheave with the belt straight off the driven pulley. this is with no slack and the belt pulled back on the drive pulley. with an inch of total slack the belt my look slightly inboard and deep into the drive pulley. Ideally the belt should look straight at initial engagement.
