I am rebuilding a 4.0 OHV out of a '94 Ranger to swap into a Bronco II. Trying to install the balancer/damper on the crank and it does not want to fully seat. I initially installed the timing cover, lightly seated the bolts, and installed the dampener to center the seal, then tightened the dampener with a 1/2" drive ratchet pretty snug expecting final torque to be over 100 ft/lbs.
Once it was tight but the balancer was not yet pulled tight to the cam gear on the crank. I checked the book for torque spec, which calls for 30-37 ft/lbs + 90*... Which is to say a TTY bolt, so I need a new bolt. The old bolt is torqued to well above 37 ft/lbs and the balancer is pretty far front the cam gear on the crank. I'm doubtful that 37 ft/lbs+90* will get the balancer snug to the cam drive gear on the crank. Balancer is aftermarket Grayworks 102028. I have not tried to install the original balancer, which has dried and cracked rubber.
Is this crank damper bolt a TTY bolt I need to replace? What do I do if the balancer, aftermarket or original, doesn't seat against the cam drive gear at 37 ft/lbs+90*? This is the early style cam drive gear taht needs to be fully sealed against the crank for the tank to seat and ensure it doesn't come loose..
