1960 Clutch push rod bushing orientation

[Donald H.]

I have attached a picture of the clutch push rod bushing that goes into the the clutch cross shaft. I can't tell from the AIM (not enough detail) to see which way the bushing goes. The 1960 AIM page is Section 6 sheet 7.00 and is the Clutch Linkage page.

I found another thread where there were some differing opinions. That thread basically end up with the OP and Corvette Central rep agreeing that the bushing is pressed into the cross shaft from the outside, thus the shoulder of the bushing ends up on the outside.

Just checking to try to verify this since there were differing opinions

Don, I just replaced an original on a '59 not long ago and the lip was originally engine side, so that's how I installed the new one. I think the CC and Paragon guys got it wrong. Your picture in the above link above shows the lip on engine side. That's a CC picture I think.


I also checked my '59 a little while ago and I replaced it years ago. Lip is engine side. I'm pretty sure I put it on as it was when it came off.

I really makes sense to me that way, as the large flange of the bolt will be against the lip side.

Also found this thread. Pic in post#5.

I did not have much luck with the replacements(2) from Corvette Central they were destroyed in less than 1000 miles. The inside bushing which I was told was oillite looks to be steel. I replaced mine with a oillite type bushing without the rubber. Personally I think the original design begs to be desired. I checked alignment and could not see any reason for them to fail, but mine looked like the second picture that Rich posted.

Thanks Rich.

Wonder way they wear out so fast with the steel bushing on the inside? I don't really see the point of the rubber unless it is to dampen any vibration back through the pedal?

Just found one at ZIP that is Poly, their listing is 'Designed for the Corvette enthusiast who wants the advantages of polyurethane (will not rot, deform, or wear-out) but wants to retain the factory look of rubber which includes a "matte" finish. Cross shaft bushing is molded to steel shell as original.'

I'm ordering one tonight.

Thanks,

I'd guess that the grease acts to deteriorate the rubber. Yes likely for vibration issues.

I need one for my '59 and I like the poly idea too. I'll order one myself as well. I didn't know they had them...... must be a new part that they stock.

Re: 1960 Clutch push rod bushing orientation

Rich in the thread you posted, Jim Lockwood used a brass bushing replacing the rubber altogether, that is what I did this winter. I found a bushing that was the same diameter as the bushing outside 9/16 and the inside was is the same as the bolt 3/8 I believe. I had to cut the bushing to the length of the shoulder on the bolt and then pressed it into the arm. I could not find a bushing that had a shoulder in the correct size, but it was a very tight fit so I do not think it will shift or spin. The ones that I had fail were not because of age or oil I think that the inner bushing being steel is the problem, original was oilite, this may cause binding and if the new bushings(poly) do not have an oilite center I think they too may fail.
Just my thought
