31  Camaro Research Group Discussion / Originality / Re: 68 power steering pump on: December 07, 2010, 09:42:29 PM
OK, I got the 6-cylinder pump out of the shed and my V8 pump out of the garage. The 6-cylinder pump has a stamp that looks like 0 4 9. The bottom of the characters is very light if there at all. The V8 pump took some very fine steel wool and I found a complete 8 with a possible character before it. The stamping is upside down when looking at it from the side. The pump in my car is too hard to read.

The location on both is on the engine side at about 10 o'clock. Set the pump in front of you with the pully facing you. Then look at the housing on the left side between the upper bolt hole in the cast iron housing and the top inlet.

I've heard that you need to turn the wheels to bleed the air out. I did that so long ago I can't remember much but I think I did it a couple times and didn't have a problem. To rebuild it, there are instructions in the Overhaul Manual or just take the 2 rear studs and 1 fitting out and the housing should come off. The cast piece has an O-ring and there are other gaskets where the studs are. I bought rebuild kits years ago from a parts vendor, I think they used to be around $12. Make sure the housing isn't distorted (it needs to be round) or it will leak.

I hope this helps.

Ed, it's been a long time and I can't remember which side but it was about half way down from the top. I recently sold a rebuilt pump and all I have left is the one in my car and one other that has thicker paint and some surface rust. I'll try to clean that one up tomorrow and see what I find. I will also try to find it on the one in my car but that might be tough.

I have a 6-cylinder pump off a 69 Nova I can look at tomorrow.

I have had a few of these pumps and most had a date code stamped in the housing. Sometimes it's faint. I can't remember what the format was. I'll look for some old notes.

Rebuilding them is easy, just remove a couple bolts and replace some rubber gaskets.

I'm not a legends judge but the 68's I found in yards years ago had the 293 BR coil. And the 69's in the yards had 293 B-R.

I used Mobil 1 Synthetic Universal Grease when I rebuilt mine. It's rated to 450F.

No, I've never looked for a 793 so I don't know how difficult it is to find one.

The one for my car is a 3857042.

The upper left bracket on the top photo is 6 cylinder lower alternator bracket. The upper right bracket on the top photo is short water pump small block V8 lower alternator bracket (i.e 67-68).

The lower steel brackets in the top photo look like brackets used when you install headers.

Jeff, what is your carburetor part number? I have a couple 68 parts carbs here if it's a 68.

I was lucky to find the correct fan spacer for my 68 L35 at a swap meet years ago. Not an easy piece to find.

Yes, you're correct, those engines don't use fixed fans and therefore don't use a fan spacer.

According to the Assembly Manual, 3927792 is correct for V8s. What is the length of your spacer? The '792 is 1 inch long.

I think what John meant was they used an engine coded for a Powerglide car, not a manual trans car.

I have an original hose and diverter valve if you're interested. Send me an email.

The 5 blade fans I have taken off 68 full size cars had 4 flat rivets.

45  Camaro Research Group Discussion / Restoration / Re: what is the correct type of oil filler tube cap ? "S rivet" or "engine oil fill" on: June 30, 2010, 07:09:45 PM
I took one off a 68 Chevelle 2-BBL engine built in Tonawanda years ago. It was stamped ENGINE OIL FILL AC-FC60.

Hope this helps.
