Random Bolt

rp2000r · Dec 4, 2017

My friend and I were out riding and heard a rattle.
He found this bolt rolling around by his clutches.
It doesn’t look like anything we could see anywhere and says 8.8 on it and letters JH.

His sled has had a new track, driveshaft and new quick drive belt.

Can anyone help identify the bolt?
Quick Drive sprocket bolt?

Thanks!

Looks like the bolt that goes through the motor strap and bolts directly to the bottom of the engine cases. There are four of those bolts on a ProRide Pro.

That would be my first suspicion as well from both the OP's description and then the photo. The thread pitch would be a further indicator as the engine strap bolts are a 10mm x 1.5mm pitch and the QD bolts are 10mm x 1.25mm Pitch. From the photo it looks to be a 10mm bolt, unless the person holding it has very small hands. The majority of other fasteners that could come loose are either 8mm (or smaller) or are a torx button head or allen socket headed bolt.

The sled in question had a driveshaft failure early on so thought it could be a QD bolt. I have spare QD bolts and it has the same markings so we need to determine thread pitch to confirm where they came from. We will also check motor strap bolts to verify they're intact. The sled has a bad vibration so could be missing strap bolt.

Appreciate the info, Ryan

Rookie question, Whats the best way to look and see the bolts? I am not at home but seems like seeing them maybe tough without removing parts.

The markings on the head of the bolt doesnt mean much when trying to figure out where it cam from. The 8.8 is the bolts strength rating.... 8.8/9.8/10.9/12.9 JH is just the brand of the bolt, the manufacture.

I good light and an extendable pivot head mirror should let you see what you need to under the engine.

One of the primary cover bolts, maybe

No those are standard with a 3/8" head.

OP, Can you post a pic sideways showing thread pitch and length please?

Quick Drive bolt?

Ended up being a motor strap bolt.
Thanks for the info guys!
