Anyone thinking of separating their Paxton supercharger ‘halves’ for a thorough clean out of the fluid reservoir may want to purchase (ahead of time) the two o-rings that seal the halves.
Those two large o-rings are fairly easy to nick or break, and I doubt if replacements could be found locally.
Paradise Wheels in California stocks them… Ed
To me, that indicates it was moisture…. Unfortunately, if the moisture couldn’t escape, it probably retreated back into the fiberglass, and chances are will return.
That was a prudent move!… Although an Avanti’s power window motor is small, the torque it develops (through gear ratio advantage) is considerable….
Much more torque than a person would normally apply to a manual window crank!
I used to look forward to receiving their catalog back in the ‘sixties’… Whitney even had complete used engines “CHECKED FOR OIL BURNING” for sale as part of their huge inventory!!
Glad it worked out!… Another important function of that same light is to alert driver if one or the other side of the car’s hydraulic brake system has failed.
As an aside…. Asking prices for used Paxton/McCulloch superchargers on eBay (for example) are going through the roof!
I wonder how many perspective buyers realize the ‘can of worms’ they may be purchasing?
Buyer beware when considering acquiring one of these 60+ year old used units!
Your JC Whitney reference made me laugh… but you’re exactly correct that items like these could be found in that great old catalog!
I was hoping there still might be a source somewhere… or even a used set…they really can’t go bad !
Your Avanti has what GM Called “Computer Command Control System”
That check engine light is part of that (emissions) system.
It should go off a few seconds after you start the engine…..If it stays on, it does not mean there is an engine problem… The light staying on indicates a problem in your Avantis emission system… which could be a multitude of items.
There’s a plug under your dashboard that a code reading device can be plugged into which may zero in on the issue.
