Belt & Secondary Clutch Troubleshooting

The Can-Am X3's secondary spring hole, belt slip, and a secondary that spins at idle or is hard to shift.

Which hole do I install my secondary spring into on the helix for my Can-Am X3?

EVP Purple: always placed in spring hole #5.
Stock spring on a 2018-2021 X3 Turbo R and 2020-current X3 Turbo RR: spring hole #4.
Stock spring on a 2018-2022 X3 Turbo: spring hole #2 on the helix.
Stock spring on a 2023-current X3 Turbo: spring hole #2 on the helix.
Stock spring on a 2017 X3 Turbo R: hole #2 on the helix.

4-seater vehicles or vehicles using a bigger tire (35" or larger) may need a shallower helix, such as a 35-45 or 40-45. This slows the shift-out and gives more belt grip; when using a shallower helix, add a little more weight to the primary weights to help with belt grip, since the shallow helix will otherwise raise RPMs a bit.
Make sure sheaves are clean and dry - worn crank seals or transmission seals can leak oil onto the clutches and belt.
Primary weights may be set up too light for the vehicle or for the stiff spring being used in the primary.
There may not be enough tension in the secondary, which can cause it to slip.
There may be too much tension in the secondary, which can cause slip in the primary.

Bushing issue on the secondary movable sheave.
Primary stuck closed enough to grab the belt - if so, tear the clutch apart and clean debris from the movable bushing and the spring retainer/stop sleeve.
Roller bearing on the primary is dry and getting hot, causing it to grab the post and spin the belt.
If everything checks out fine, a float mod can be a fix.
Wrong belt (too short).
Broken or weak primary spring, causing engagement at a low RPM/idle.

Thrust washers on the secondary need adjustment for belt alignment/deflection.
