Zenoah torques

Hi guys

I made a torque chart for Zenoah motors last night ( I was sick of my little piece of oily paper) and thought I'm going to share it.

Crick-crick…. Tight…

A light coat of oil all over the bolt before installation always helps get you a good torque

Dang! I thought when it slipped a flat on the hex key was when it was to proper torque.

Well if you use soft stainless steel screws

Mike,
I was always told that when oil is used (wet torque) that the torque should be lower. I always clean my threads before torque (Dry torque). When I was in manufacturing our drawings would have a callout if oil should be applied, never apply oil on a standard torque (dry torque).

don't need no torque specs when I have a calibrated wrist!

Strip them and back them off 1/4 turn that way you know they were tight.

I hate it when righty tighty goes righty loosey..

From ARP…

Recommended torque is equal to 75% of the fastener’s yield strength.
ALWAYS LUBRICATE FASTENERS PRIOR TO APPLYING TORQUE TO ENSURE ACCURATE READINGS.
Using ARP Moly Assembly Lubricant or 30-wt. oil

Frank,
My 45 years working at a military contractor plant, if people started to apply lube/oil to all bolt thread at will, boy would that stop production and initiate a mass recall on installed hardware. Of course government drawing specs are more detailed for better control of design intent. Ha stripping out threads sells more replacement parts.

Every application is different, common sense should be applied, when selecting whether to use lube or not… as well as the conditions the fasteners must live in..
different conditions require different types of lubricants.
Dry torque does have its place, but to just blanket state that everything should be dry torqued is wrong.

IE: I would never dry torque a new set of rod bolts when building a BBC with steel rods..

But if I was bolting suspension hangers on an 18 wheeler chassis, chances are I wouldn’t use any lube..
Also whether the bolt is in shear or compression/tension comes into consideration as well..

Again, common sense applies..
To each his own…

Years ago I was next to butch the boatman and watched him tighten down cylinder allen head bolts
The t handle allen wrench bent 90 degrees further than the bolt turned,
I cringed, he saw the look on my face and said, hey kid that's how tight these heads gotta be!
I will never forget that one!

Common sense? What’s that?

On this subject you guys have definitely shown that you can walk the walk as well as talk the torque !
