I just measured my belt play and it was 1.5 inches. Can anyone help with what shims to remove?

 

1.5" coverts to 38.1mm deflection. Wow thats loose, are you sure you rotated the rear clutch enough to drive the belt to the top. It had to be squeeling like mad. The normal deflection range is between 22-27mm. Anyway, removing the following shims will reduce the deflection by this amount.

0.6mm shim = 7.8mm of deflection
0.8mm shim = 10.4mm of deflection
1.0mm shim = 13.0mm of deflection
1.4mm shim = 18.2mm of deflection

If you have a 1.0mm shim remove that and your defection will be around 25mm (38.1mm - 13.0mm = 25.1). If you don't then try to come up with a combination that will put you in the 22-27mm range. Tighter is better than loose so get as close to the 22mm as possible.

 

Thanks for the info. The quad only squeeled on take off in high and mostly on an incline.

 

Your belt /pulley halves should still be fine, if you did run too long with a loose belt. See nyroc's 650 site. It has ALL the info you need for belt maintenance. GOOD LUCK! I like that name"italianmuski"!
UHHH... BTW---- where did you get the green/red plastic? Is the green, the Kaw racing(slime) green? Do you have pix?

 

I have 2 sets of green and 1 set of red. I plan on racing and want the red plastic for the races and the green for trail riding and hunting.
