The only reason you would need to remove the harmonic balancer is if you were trying to remove the timing cover. The water pump is bolted to this cover. Just remove the four water pump bolts and take off the pump. Very simple process.
Good luck. _________________ PontiacRegistry.com... building the single largest source of Pontiac information, services, and entertainment in the world! |

Yes I figured out,, My motor has 1/8"of oil/sludge from years of neglect. I removed to much, however I plan on replacing gaskets ,seals etc. Now I am wondering if the threads on the ballancer bolt is reverse? How can I find if the motor turns to the right? thanks _________________ |

Most engines turn clockwise as viewed from the front. Picture your timing mark on the balancer looking at the passenger side of the engine coming up from the bottom as you move your distributor around when setting timing.
The '57 Shop Manual does not mention anything about counterclockwise threads and I'm sure it would point that out if it was the case. In my mind I see putting a socket on it, handle to the right (while facing the engine, and pulling up (counterclockwise) on the bolt. It is supposed to be at 160 ft. lbs. and with age may be a bear to move. Leave your spark plugs in so you have engine resistance. If you have room for an impact gun, that really helps rattle things loose.
If you're going this far, I hope you are going to replace the timing gears and chain too.
Good luck. _________________ PontiacRegistry.com... building the single largest source of Pontiac information, services, and entertainment in the world! |

I'm not too familiar with the early V8s, but the later Pontiac V8s were notorious for jumping a tooth (or more) at about 125k miles. At least that was my experience.
Yell if you need any help or have any questions. We will try to help. _________________ PontiacRegistry.com... building the single largest source of Pontiac information, services, and entertainment in the world! |

Attached you see the color of blue green hirsh sent me for engine paint
A bit bluer than the engine. I realize it is a filthy mess but working on that. I have a theory, I researched that the abrahms tanks used these hydromatic transmission, it appears to me that Pontiac purchased the army green paint after WW2. ?? _________________ |

The Hirsh paint is no where near what it should be. As a matter of fact, I have never seen a Pontiac with such dark blue color.
Yes the Hydra-Matic (not hydro) was used in tanks in WWII along with the Cadillac flathead V8 engines. But PMD did not use army green paint afterwards.
The Pontiac of the '30- and '40 (maybe into the early '50s, not sure) did use a rear dark green paint (not a very pretty color!). Then with the new V8s they went to a greenish-blue color before finally going to the famous Pontiac light blue (which even had many variations over the years).
Below is a '57 engine from a Barrett-Jackson car, the Eastwood color (and link) that looks pretty close, and a shot from a '57 Pontiac brochure that looks pretty much like the color you want and that Eastwood has.

I ran into this on my '63 1st design (4-bolt w/p) when i replaced the timing chain with a large pin Cloyse chain. it ran for about 5k and then jumped again. i went back to the OEM Morse chain and had no more trouble. If i had to do it again, a double row bicycle type chain set is what would be installed. |
