Torque for the Timing Belt Tensioner Bolts

Post by bofler »



So, haven't been able to get a definitive answer on this in manuals or online. Does anyone know what the torque specs are for the timing belt tensioner bolts? Not sure how precise this needs to be, especially because at least one of the bolts is in a place that won't really allow a torque wrench. Just to be super clear, a photo of one of the four bolts is attached.

from my gl1100 FSM ... tighten the tensioner bolts and re-check valve timing.

from my gl1000 FSM ... tighten tensioner bolts securely.

no torque specs given anywhere that i could see.

Exactly. Manuals don't give any info on that, even though these are pretty crucial, and there's nothing definitive that I can find floating around online. From videos I've seen, looks like most people just snug them down about as tight as you can with one hand.

Do people use loctite on these bolts?

Loctite is not necessary. The tensioners are on the "slack" side, not the "pull" side of the belts. They don't see much force, their main job is to keep the belts from flapping.

There is no published spec for these bolts. Based on their size, and the fact that they are threaded into aluminum, my general guess would be about 15-20 ft-lb. But honestly, I just do it until it feels about right. But that's based on many years of "feel" experience. :)

Honda Service Manual has a listing for different bolt sizes as a general torque value. Find the bolt size and use that torque value.

Later manuals do, but the GL1100 service manual does not. This is from the GL1500 manual:

Generic torque values from GL1500 manual
