outer primary torque
« on: October 23, 2019, 05:13:56 AM »
My service manual says to torque the outer primay bolts to 18-22 lb/ft. Same setting as the inner primary???? I think this is a misprint. What does anyone elses manual say? Thanks, Frank

84-108" (inch)  pounds
Ignorance is bliss, and accuracy expensive. How much of either can you afford?

Stay on the low side of the TQ. specs on these older aluminum parts. Don't ask me how I  know.

90in-lbs is really friggin tight! NO MORE than that. The HD manuals say to torque some 1/4" bolts to 120in-lbs, they will pull good threads right out at that setting!

I guy I used to work for wrenching on HD's told me once, that his customers expected me to use a torque wrench on everything.

I had just finished some work on a motor sans-torque wrench and I grabbed a torque wrench and told him to check them.

He never said another word about the use of torque wrenches...

Time-Cert kits are a requirement for owning a shovel and really should be for older Evo's.

Head bolts, case bolts, oil pump bolts all get a torque wrench, I can tighten them evenly without, but I'm not THAT good. Just like rod and main cap bolts on a car motor.

When it comes to cam cover and primary screws I do not use a tq. wrench as even at the low specs the threads will still strip out as the spec is to high from the factory especially on older cast aluminum.
