Power Steering Pump Compatability

Post by LurkinLimey »

Hi Everybody,
Will a stock power steering pump and brackets from a 440 fit a 383?
Is the pulley the same?
Guessing it will swap, but though I'd check.
Looking to replace an aftermarket setup on my '68 Satellite and a 440 set has come available.
Thanks for any help.

I'm almost 100% sure they are the same on the 383 and 440. Think the pulley may be solid. Mine was buckled so I picked one up that had been on a Jensen. It was the 3 spoke type off a 440 (mine 383). I just ran a piece of string around all the pulleys and went to Halfords and found a belt that had the correct internal diameter.

If you have to pull the pulley off, use a puller that gets it off from the centre of the output shift and not the edges or it will buckle.

Also, check that the rear bracket that bolts to the saucepan section of the pump is the correct one. If it isn't, it will leak. I used one of those metal washers with a rubber insert to be 'belt and braces' as just a fraction of a degree off flush is enough for it to leak.

One of the more experienced members will be along shortly to confirm. Let me know if you need a pic of my set up and I will sort for you.

Worth noting that there are 3 pumps, Thompson, TRW and Saginaw. To further muddy the waters, I'm not sure if they are interchangeable. I changed like for like when I replaced mine. I have read somewhere that Thompson is TRW so maybe only 2 but again I'm not sure.
