As everyone is preparing their snowmobiles for the upcoming winter season, I’ve received, and have seen, more and more comments from those of you looking to upgrade your current drive/driven clutches to Arctic Cat’s new ADAPT clutches.
If you are unfamiliar with Arctic Cat’s ADAPT clutches, their design and benefits, please read this story HERE.
Arctic Cat created the following parts and tuning guide for both the DRIVE and DRIVEN ADAPT clutches. If retrofitting, this guide is targeted to 2016 and newer models.
Pay special attention to the fourth column notes on the charts, and it’s recommended a new drive belt is purchased and used when installing NEW ADAPT clutches.
ADAPT DRIVE CLUTCH – RECOMMENDATIONS BY MODEL, YEAR & ALTITUDE
ENGINEERING DRIVE CLUTCH NOTES
- Can be used with existing Driven Clutch
- One of the first DRIVE notes below (fourth column), is the need for the hardware kit (cam arm pins, fastener and thrust washers). This was a change to our uncalibrated clutches as we install the calibration in Thief River Falls, so service clutches (uncalibrated) are the same as what the factory receives for commonality.
- E-start rings and damper (Non-ES) rings are carry-over. We recommend using new hardware for installation on a new clutch as the hardware has patchlock. The ring gear fastener number is 2623-317 (qty 6 needed).
- There have been some questions online for a shorter clutch bolt. Some 2-stroke MY23 snowmobiles will have the shorter clutch bolt (2623-308) and that is used with the “old” bolt spacer from MY16-21. (Service parts availability timing is TBD)

ADAPT DRIVEN CLUTCH – RECOMMENDATIONS BY MODEL, YEAR & ALTITUDE
ENGINEERING DRIVEN CLUTCH NOTES
- Can be used with existing Drive Clutch
- An ADAPT driven cam can not be used in a MY16-21 TEAM driven sheave due to channels in the TEAM sheave and cam castings. A MY16-21 Cam can be used in the ADAPT driven though.
- Arctic Cat has created a uncalibrated service parts driven clutch (0726-446) which is listed in the Driven Clutch table above. It has an added threaded hole for the belt deflection screw, should a consumer need a driven for their sled prior to the idler drive system.
