67 inline 6 harmonic balancer ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

sleepertruck72 · 08-28-2009, 08:49 PM

On a inline 6 250ci, I was going to swap distributor to an HEI. The harmonic balancer doesnt have a bolt so I can turn the engine to #1 cylinder on TDC. It seems to be held by the key, and even the 3 holes for the puller arent threaded. I cant post pics thanks to a lost battery charger. Has anybody else encountered this problem ? Thanks for any help.

Take out #1 plug and hold your finger over the hole while someone bumps it over.When your finger gets blown off the hole you're on #1TDC.

I concur, that is the way that I usually do it. Over the past 25 years my daughter has gotten pretty good at bumping them over with the key.

Clean your timing marks first though and make sure that they are easy to see.

I usually pull the distributor cap off and watch the rotor even if I am bringing the engine up on compression with my finger in the #1 spark plug hole.

Don't be surprised if it takes several before you get it where you want it.

If you have a remote starter button you can bump it over yourself.

I just grab the belt and pull the motor over while watching the distributor rotor...

That sounds easier than the flywheel method. Maybe I will just get a battery first, then I can turn it that way. Thanks passthebuck

Thanks for the responses. I've had this truck in my backyard for almost 3 yrs. and I got alot of work to do !

This. The compression is so low I usually just press the belt against the water pump pulley and rotate.
