1967 Power Steering assist cylinder

[Timothy B.]

Finally got around to installing P/S on my 67 car. I need to replace the slave cylinder because the chrome rod is wore at the center position. Is this part still available from GM or NOS or???

I am not interested in rebuilt cylinders.

Also, Can anyone tell me the grade and length of the two long bolts that hold the P/S pump to engine block.

Thanks in advance for the help. Tim

The power steering cylinder, GM #5691112, is no longer available from GM. Even if it were I wouldn't expect that every nuance would be the same as the original cylinder.

I do agree with you 100% regarding not wanting to use a "re-manufactured" cylinder. I wouldn't use one, either.

The good news is that the reproduction cylinders appear near-identical to the originals. I'm not sure that Saginaw actually manufactured these cylinders and/or if they continued to manufacture them in later SERVICE. If not, it may be that whatever firm did manufacture them continues to do so for the reproductions.

Perhaps Jim Shea will be able to advise us as to whether they were ever manufactured in-house by Saginaw.

The long bolts that retain the small block power steering pump BRACKET to the engine block are 3-1/4" long and of GM 280M material grade (3 lines).

Thanks Joe,

I hope Jim Shea posts with some info. The P/S pump has a date code of 009A 8 so I assume it's a 1968 pump. The relay rod is the thicker 7/8" and bracket is the long bolt type. I need to double check to make sure the other support bracket is correct before I mount pump.

The relay rod is the 69-82 style rod if it's 7/8". So, it's likely that power steering was added to the car at some point.

Re: 1967 Power Steering assist cylinder

Saginaw did manufacture the assist cylinder. I do not know how long after 1982 they continued making service parts. The 5691112 drawing has the last revision date of 27NO87. The date code location was changed. It doesn't indicate where the original date code was located.
Date coding was XXX Y
Where XXX was day of year (001 thru 365)
Y was the last digit of the year (8) was 1968 or 1978
So it is probably pretty safe to predict that Saginaw manufactured the cylinder assembly at least through 1987.

Re: 1967 Power Steering assist cylinder

Thanks Joe and Jim, I appreciate the info.

Looking at this steering relay rod and valve and reading the archives on some of Jim's info it appears this valve is of the 1976+ manufacture time period. The in/out hose guard is flush and dust cap has no marking. I can't remember if the P/S pump came with this but I think it's the 1967+ version with the larger seal..

I have decided to install and check before I spend $$. I also have the steering box off to clean and adjust. Can anyone give me the part # for the grease seals, sector and worm. This box was greased and it's full to the point the engine heat had grease all over the place because to much grease.

worm shaft seal--GM #5677650---discontinued. Same as National #340495.

pitman (sector) shaft seal---GM #7801626---available. Same as National #313842.

Re: 1967 Power Steering assist cylinder

Thanks Joe, I will try to find the seals locally.

Re: 1967 Power Steering assist cylinder

Tim,

Bolts I have seen holding the craddle are 3/8-16 x 3-1/4" grade 8 (some times 3-1/6"). The 2 bolts that hold the belt gaurd are 3/8-16 x 1/2". The bolt to attach the pump to the bracket in front is 3/8-16 x 3/4" and on 63-69's the bolt that attaches the bracket to the motor mount is 3/8-16 x 1" recessed hex w/captured split ring lock washer. I was just in the process of putting togeter a few set of these when I saw this post.

Re: 1967 Power Steering assist cylinder

I noticed that Tim had the date code to his power steering pump. I am looking for early power steering parts. I thought that the date was inside the pump. Did I just answer my own question? Any help locating good correct power parts would be greatly appreciated. Thanks, Jeff

Re: 1967 Power Steering assist cylinder

The date coding on the Saginaw P-pump has always been on the side of the reservoir in the same general location during C2/C3 production. The coding has generally been five, six, and a possible seven character code 000 X0X(X?)
1963 through 1966
Date stamp had a five digit code.
Date stamp location at 1 o'clock on side of reservoir.
The first three digits were the day of the year (001 through 365).
The fourth digit was an S for Saginaw
The fifth digit was last digit of the year (3 for 1963)

1967 through 1974
Date stamp was a six digit code.
Date stamp location 1 o'clock on side of reservoir.
The first three digits were the day of the year (001 through 365).
The fourth digit was the assembly station (L or R).
The fifth digit was the assembly shift (A, B, or C).
The sixth digit was the year (7 for 1967).

1975 through 1981 Early
Same coding as 1967/74 except location on side of reservoir was allowed to expand between 1 o'clock and 6 o'clock.

1981 Late through 1982
Possible seventh date stamp character added (the drawing is unclear on this.)
Date stamp location on side of reservoir between 1 o'clock and 6 o'clock.
The first three digits were the day of the year (001 through 365).
The fourth digit was the assembly station (L or R).
The fifth digit was the assembly shift (A, B, or C).
The sixth digit was the year (1 for 1981).
The seventh digit was the letter X or R for a round wire retaining ring?





There was an alternate date stamp location (on the back of the reservoir) that was added in 1984 for service. So no production C2/C3 reservoirs should have a date code on the back face of the reservoir. There may have been a vendor identification on the back face of the reservoir.
