Polaris Upper Idler Wheel Mounts - Torque / Thread Locker?

[mngolf4]

Reaching out to see if someone knows the proper torque for the M10X1.5X35 bolts that secure the upper idler wheels on a 2013 800 Switchback Pro R (these are the 2 smaller idler wheels on the top at the rear of the suspension). Also, are and should these bolts be re-installed with thread locking compound.

Thanks in advance.

Can't help you with the torque other than TIGHT but I would use BLUE Loctite on the bolts.

I'm going to check the bolts to see if I see any signs of thread locking compound. Anyone know the proper torque?

Not knowing what grade you have you can look here.

Grade of bolt is determined by the markings on the head. if you use loctite use the lubricated spec, otherwise use the dry spec.

Thanks Elf. The bolts are grade 8.8 and I've seen anywhere from 37 to 43 dry. I think I'll tighten them up good and then see what 30 ft-lbs. "feels like".

Well, didn't appear to be any locking compound on the bolts. I found 2 other spec sheets that had the max torque on an 8.8 grade (specifically, vs. "8.8 or 9.8") at 37 ft-lbs so I went with that. Seemed about right.
