I own a 2006 Ski-Doo Summit X 800 and was servicing my clutches. When I went to re-assemble the primary I noticed that there was looks like a “washer” at the bottom of one theÂ 3 guides for the pucks. There are three guides and only one has this washer like piece secured at the bottom of one of the guides. Is this for balancing or a shim of some sort? Local dealers have no idea what it is.
What youâ€™re seeing is a pressed in place â€œbalance shimâ€ that is installed, as needed, into the sliding half of the TRA primary down in the bottom of the slots for the â€œpucksâ€, as you call them. Not all clutches have these balance shims, nor will all of the guides, as they are installed as needed to precision balance each sliding sheave individually. Do not remove them. Leave them in place!
A small number of 2004 models had these shims come loose, but since then the process for installing the shims was improved so this should be a non-issue.
