    Arrow Damper Bolt Tightening Fixture

    Here's a photo showing what member M.J. McCarroll uses when torquing the damper bolt to the recommended 200 ft-lbs.



    The damper bolt can be removed using an air wrench, but this fixture allows easy bolt torquing if you're working by yourself.

    Thanks M.J. for sharing!

    Definately a good little device.
    I usually use the 1/2" impact and zap the bolt good with a little blue loctite on the threads.

    I recently received an email from a member in Norway.

    Good morning.
    I am an owner of one Chevy Truck 1982 6.2L Diesel. After 29 years, I was thinking that the Balancer should be renewed. So, I renewed it to day, with the engine in the car. Also renewed the shaft seal.

    When I started the Engine, the vibration became worse, at idle speed.

    The new Balancer is from Rock Auto. I'm planning to renew the motor mounts. Should I install the old Harmonic Balancer, or will it become better after a while? In advance thank you for your replay.

    I emailed back with the following message:

    Hi John,
    There are harmonic dampers being imported from China. These are pure junk. Some have failed soon after installation. Always insist on genuine GM parts. If the damper you bought is a GM part, I would re-install the original damper, to see what develops. If the engine smoothness is better, I'd return the damper you just bought, and not run it.
    Jim

    He came back with:
    Hi Jim.
    I read "made in China" on the box label for the balancer.
    DORMAN HARMONIC BALANCER.

    I will talk with my local AMCar Dealer here in my hometown to see whether they have an original GM Balancer to give me.

    Jim,

    You should point him to GMPartsDirect.com. He can order his Genuine GM damper there and have it shipped anywhere.

    Pioneer makes a good original design type balancer.

    The Dorman one is junk, I almost had to beat up on an O-Reilly's part guy that insisted that the Dorman and Pioneer balancers were the same. Not even close, visually different. Some kind of hard silicone for damper on the Dorman, real rubber (like the factory balancer) on the Pioneer.

    Then there is the made in china part too...

    Oh, Robyn knows a good deal about these rattle box engines, but the Impact idea is a very bad one. Make a fixture or use my 1/2" extension wedged in a strategic area to lock it down and tighten that guy to the required 200 ft. lbs.
