View Full Version : Is there a difference between 1969 camaro 6 cyl. & 8 cyl. PS Pumps?
z/27 camaro Dec 8th, 01, 04:24 PM also does one of the hyd hose connections on the back of the pump,[actually a tube ]come straight out of the middle, about 3/4 of an inch then curve down on an angle about 2 inches?
does the resavoir filler neck on the 69 ps pump angle forward slightly??
does this sound like this pump is off a 69 camaro??
thanks guys

TJS69 Dec 8th, 01, 10:14 PM I believe the 6 cyl pump has a longer shaft than the v-8. Also I believe the answer to your other questions are yes also. (could be wrong - memory is the 2nd thing to go.)

z/27 camaro Dec 8th, 01, 10:18 PM thanks tjs69....do you know how long the shaft is in comparison to the 8 cyl.??
TJS69 Dec 8th, 01, 10:24 PM Not sure. I know someone else was having a pulley alignment problem with this. Try doing a search - I remember he even had pic's (links)

Eric68 Dec 8th, 01, 11:06 PM That very well could have been me http://www.camaros.net/forum/wink.gif I have a 68 with the SWP setup though so I'm not sure if my 68 experience applies to your 69.
I think the 6 cylinder pump is 1/4" longer and the return tube is longer too - points straight down. I made my 6 cyl pump work on my V-8 by making a 1/4" spacer for the p/s crank pulley and cutting the pump's return tube down to clear the frame. No problems at all with the setup.

z/27 camaro Dec 8th, 01, 11:20 PM hey eric68...i was just going to put up a thread to see if you were out there. LOL
but if i put my old ps pully on it it should work ......right?
i gotta find out what this ps pump came off of!
i was hoping some one with a 69 would no what the return tube should look like. hhmmmmmm

If you want to keep this message string near the top of the list, just post a reply to it and it will pop to the top of the list.
Posting additional new message strings saying to look at THIS message is not the best way to go about it.
I see you waited only SIX MINUTES between posts that said the same thing!
Also try using the "search" link on the upper right corner of this page. Don't forget to search the suspension and General tech sections archives for info.
A 69 V8 PS pump should have a return line coming out of the rear corner of the back of the pump and curving down under it. The pressure hose will have a 90 degree fitting on it and the return line will be right next to it. I doubt there is any difference in pump body or shaft between 6 cyl and V8.
The pulleys and return line are probably the only difference.
The CRG site has a complete list of pulley numbers for all first gen Camaros. http://www.camaros.org
Thanks and good luck.
David

z/27 camaro Dec 9th, 01, 11:31 AM thanks david........i'v been humbled about my threads! LOL
i'll take your advice in the future.
thanks for the info on the return tube, thats what i needed to know.
i think mine is off a 68 camaro........do you think it will fit? or will the tube hit the block?
do the 68's mount diff?
davidpozzi Dec 9th, 01, 08:50 PM Just tryin' to help on the posting thing, no big deal. http://www.camaros.net/forum/smile.gif
Check my suspension page below. There is a steering page with some photos and PS part numbers too.
The 69 uses the long water pump and the PS mounting bracket hangs from a boss on the pump with a long bolt throught it.
The 67 and 68 style is pictured on my steering page.
I don't know if the tube will clear or not. If you are using the long water pump, mock it up and see. It would be fairly easy to move the tube on the pump "can".

TJS69 Dec 9th, 01, 08:56 PM I have consulted various parts suppliers books and they list a different pump for 6 cyl and v-8 applications.

Eric68 Dec 10th, 01, 05:55 AM You know I spent a lot of time trying to figure out whether my 6 cyl pump would work or not. I even stopped by National Parts Depot in Detroit and they were kind enough to let me measure one of their V8 pumps off the shelf for comparison. Everything looked like it would work until I tried to get the pump in - my point is that the only way to tell for sure is to give it a try. there are very few things that I would say "just try it and see" - this is one of them!
Keep in mind that there are a couple different bracket setups too that will affect pulley alignment and clearance for the return tube and high pressure hose fitting.
Good luck and may your knuckles be spared from the wrath of the mighty p/s pump!

i looked at the pics on your page........now i have another ques........are you saying the punp in the back of the photo is 69!!??
i'm under the impression that the the 69 camaro had the same round looking pump as the 67 and 68!?
the reason im so amazed is that i have that same pump on my car now [the one in the back of the pic]and most people tell me it is wrong and also all the 69 camaro's i've seen lately have the round style on them [the pump in the front of the pic]
tell me i'm not chasing my tail here. LOL
KevinW Dec 10th, 01, 07:52 AM Another item to look for is the type of connection for the pressure side. From looking at the repro catalog's pictures. the V8 connection should be male on the pump side. I have one, but I have a couple that have the female end on the pump side. What are these? 67,68 or some other car?

davidpozzi Dec 10th, 01, 03:53 PM The pump in the back with the square reservoir - I have found out it is a later pump that I'm going to put on my 69. I may have it labeled wrong, but the brackets and pump return line are all like a 69 has.
A 6 cyl pump might have a lower pressure setting inside and might have a different pump can, or stamped housing, but I believe the basic pump casting is the same as a V8.
As far as I have been able to find out, GM only made this car pump and a larger truck pump only used on very heavy trucks, not pickups or motorhomes.
A correct pump should have the lower return line, a male outelt fitting, a small reservoir. I don't know if it should be angled forward or not.
The pump shaft has to have a nut on it. If it has a hex like an allen head and no nut, the shaft is larger and early pulleys won't fit.
