2015 pro 600 drive train clunk

[orangecrate]

I have a 2015 pro 600 155 with belt drive. It makes a clunk at clutch engagement. Forward or reverse, any ideas?

Thanks!

Excessive belt to sheave side clearance?

If it is not the normal forward / reverse play in the secondary helix? Then Check your bearings; It was far more common on the '13's, but worth checking anyway. The top bearing on the QD side has been know to allow the shaft to spin inside the inner race resulting in excessive clearances. The other known issue is the PTO driveshaft bearing / aluminum stub end of the driveshaft. A lot of the ones of come across are not a press fit as they should be, and the stub end spins inside the inner bearing race which also results in excessive clearances in as little as 300 miles, being the stub end is aluminum.

Try changing your clutch belt. As mentioned before, side to side clearance makes these things clunk. I went through this on a 2010 RMK 700 and thought the chain was loose.
