One of the many new pieces of technology on the 2012 Arctic Cat snowmobiles is the Torque Control Link (TCL), a link/plate that ties together the engine with the jackshaft. With a fixed distance between the drive and driven clutch, belt performance (and longevity) and clutch performance are greatly improved.
Above is the photo that’s been used in many different media to illustrate the TCL. When some owners of 4-stroke-powered 2012 Arctic Cats did some poking around, they were alarmed to discover that this exact link wasn’t included on their machine.
Which left them wondering if there is a TCL on the 4-stroke ProCross and ProClimb sleds?
The answer: Yes.
Differences in the dimensions and architecture of the 1100 4-stroke twin compared to the 800 H.O. (below), as well as the 600 Sno Pro race engine, necessitated a different link. While the link’s shape and attachments points are different, it serves the exact same function of maintaining a fixed center-to-center distance between the PTO and the jackshaft.
