My ‘68 Polara 383 2Bbl has the original 4-5/8 pump with the flat end pully shaft . And not the larger 5-1/8.As mentioned that is the larger 5-1/8", also called 1.2 for displacement. Per FSM & parts book that is the ONLY pump that came on 68 C-body big block. Putting that butchered POS reservoir back on would be a crime against C-bodies, get the right one!
My memory regarding exact details of what I did 22 years ago is not crystal clear. I do recall I removed the shaft assembly including the spring-loaded slippers & that negated any need for a special tool to remove the seal because that exposes it. The part you're talking about is the spanner nut, it threads out counter clockwise. In the manual they show removing it with a steel drift but I would use brass or a piece of copper pipe in a pinch so as not to beat it up. I have a few tools I use for removing stuff like that that most wouldn't have. I usually look at the stuff in the manual & use best judgement if they call out some unobtainable special tool. The trick they show using the wire to compress the slippers worked great.
I stand corrected on that then. Very confusing, parts book doesn't really say what specific engines get the small pump but I formerly had a 383-2V Newport that had the big pump but did have AC. The 68 Chrysler/ Imp service manual doesn't even mention the smaller pump.
Here's the tool they use to pull the seal. It looks to me like it screws down into the seal and grabs/destroys it and pulls what's left up.
For the Imp it only shows the big one in the parts book. It must have been a weight thing. More weight in the engine compartment (A/C) required more pump to steer?
Per the 68 service manual there is only one pump for all Chryslers & Imperial. This contradicts part book. Not the 1st time I've seen that happen.
Not mine, and I don't have one, otherwise you could borrow it.
If you do, put a couple punch marks in it to screw it back into the same position.
You need 3 marks, one on housing, one on spanner nut, & one on seal insert. Use the FSM or you'll be working blind!
Looks like I can eat off that! Nicely done. Red compression clamps and neatly routed ground.
Is your rag joint/steering coupler in good shape? That's what we called it. I would only steer while it's in motion - not staionary. I had to replace mine with a unit from British Leyand designs, unfun.
