Title: Torque for clutch spring bolts?
Post by: Sovereign on April 08, 2018, 03:51:57 AM
Just recently bought a 92 gs500 for a low price, needed a new clutch so I grabbed one first time ever doing a clutch and I bought a 1/4 inch torque wrench grabbed the specs online and went to work. set the wrench to about 4 pounds, or 48 in lbs on the wrench and put the spring and bolt back in and it just snapped on me. luckily what was left of the bolt came out. Not really sure what I did wrong

I've always tightened them down choked up on the head of the ratchet, and once they stopped given them like a 1/8th of a turn more. and yeah they are pretty easy to get out once snapped.

So it makes sense why my torque easily snapped it if its that easy to get it tight. damn. Im considering running to home depot and picking up the same bolt to slap it in

Torque spec is 4 to 6 Nm (so 3 to 4.4 ft lbs or 35 to 53 in lbs), so you were within the manual's limits.

Don't take it as condescending, just eliminating variables (only asking as you said you bought a 1/4" one), but was it your first time using a torque wrench? If so, the click can be quite easy to miss at such tiny torques, which could be the issue.

Get a torque wrench that reads inch pounds BTW for bolts like this.

12 inch pounds = 1 FT.LB

Probably just missed it then - you got the broken one out though so no big deal!

48 in lbs really is a very small torque, you shouldn't be putting much force on the torque wrench to get there.

When I first started I found doing this helpful to get a feel for low torques using the torque wrench:

Use a socket to attach it to a highly torqued fastener such as the rear axle nut (has a spec of 36-58 ft lbs), and test out different torque settings on the wrench and try to feel for the click. As long as you stay well away from the nut's spec, you shouldn't have any risk of undoing or over-tightening the axle nut. Start from a low torque and work up, being gentle at first - if you find yourself applying what seems like too much pressure for a low torque (stick to < 15 ft lbs), then just let go and try again.
