— How to install it on the Wolverine X4 —
If you’re doing a lot of high-altitude, technical trails or wanting bigger tires for your 2018–2019 Wolverine X4 (or new Wolverine X2), Yamaha has an inexpensive accessory—the oversize tire clutch kit (part number BG4-E63H0-V0-00, $49.99, X2s may have a different part number)—for you. The kit includes eight rings called “primary sheave weights” that replace the OEM weights and engage the clutch much quicker. The setup is really ingenious in that it doesn’t require a press or specialized tools to change the sheave weights once you remove the primary-clutch sheave.
However, getting the CVT cover off to access the primary clutch does require specialized tools, and Yamaha recommends Wolverine X4 owners have the work done by an authorized Yamaha dealer or qualified mechanic. Being adventurous types, we took on the project ourselves, and it turned out to be just that—a real adventure.
Dating back to the first days of the Yamaha 660 Rhino and then the 700, we have only blown one Yamaha CVT belt. On a Baja Rhino Tour with Greg Bringle, we blew a 660 belt after a particularly abusive beach photo session. To change the Rhino belt, Bringle removed the driver’s seat and dismantled the seat base to access the CVT cover, and it took about an hour to complete the job.
The Wolverine X4 is more complicated than that. If you blow an X4 belt on the trail, a well-stocked toolbox isn’t going to cut it; you’ll need a tool chest with professional power tools and swivel extensions. We had to remove both seats and the engine cover to get to the console. Then we had to remove the driver’s seat rails, left-side trim with the rear 12-volt power port and left-rear door latch to remove the left-rear floorboard, the floorboard brace and driver’s seat/seatbelt subframe to access the CVT cover. Here’s the step-by-step process that will save you big bucks.
