The balancer should not go on so tight as to break the bolt or one should not be so ham fisted as to break the bolt. You use the flywheels own weight as inertia to keep it from spinning.Ĭan you put a harmonic balancer on too tight? It’s kinda like a poor man’s impact gun but it works. Or, hit your rachet with a hammer fast and hard. Put lubricant all over the balls Use a bar of some sort and position it on the teeth of the flywheel and the frame. Or you could just use a impact wrench (rattle gun) and tighten it up really tight if you want the easy way out. Which means usually wedging the flywheel some way. The only way to tighten the harmonic balancer bolt properly is to lock the motor up somehow and tighten it with a torque wrench to the correct tension. Tight yes, but not tight enough to wreck any tools trying to get it on and off. How do I stop my harmonic balancer from turning?Ī common practice is to remove the inspection plate on the bottom front of the transmission to expose the flexplate/flywheel, and use a heavy screwdriver or prybar in the teeth and against the block to stop the crank from moving. (3) Tighten the bolts temporarily with tightening torque of 44 N (2) Apply engine oil to the crank pulley bolt seat and thread. (1) Clean the crankshaft thread using compressed air. Hemi426, smaller Chrysler and larger Chrysler motors should have a harmonic damper bolt set to 135 food-pounds. Larger Chevy vehicles should have a torque of 85 foot-pounds. Torque Ratings Smaller Chevy models should have the harmonic damper bolt set to 60 foot-pounds. What is the torque on a harmonic balancer bolt?
