View Full Version : Synchronizer question

I know the 3rd. gear synchronizer is bad in the 63 Lark overdrive transmission in my 52 Commander, but lately I can't get it into [u]any</u> gear. I adjusted the clutch and that helped, but later it did it again. I took it out of OD and then I could get it into gear, but later it happened again and once again I came back later and it went in gear just fine.

What is going on here?

If I had to hazard a guess, I'd think you have an issue with the clutch linkage. The clutch linkage for the late, suspended-pedal cars is... well... what's the word I'm looking for? Crap. Yes, that's it. Usual culprit is severe wear/bending of the pushrod, although a close second would be rotation of the "ear" on the little cross-linkage thing. Fix is to take a known-good one to use as a pattern, rotate the ear back where it's supposed to be, and weld it in place. For the pushrod, you could make one out of some clevises and grade-5 or grade-8 all thread, although that will make adjustment more difficult (have to drop one end to lengthen/shorten linkage)

The car has the 63 tranny but uses the floor pedal of the 52. Would that set-up be causing the problem, and why would it work sometimes and not another?

hmmm.... that's different then. I'm not familiar with really anything pre-53 so I can't say whether that could be your problem or not. But if you do have the rotating linkage between the pedal and a socket mounted to the trans or bellhousing, I would check and see if that ear is rotating on the splines. It does kind of sound like your clutch adjustment is tightening up as you drive.

From my understanding The shaft that goes from the clutch pedal to the clutch can slip. I have not had this problem with my 51 but was told if I do to weld it.

Yepp, that's true. My grandad welded the shaft in my uncle's '51 several years ago, and we've never had any trouble since. :)

If one of the facings comes off of the clutch disc, this can give you an intermitent no shift problem.

Good thing you caught that, Leonard! Fill it up and make sure it all still works. :)
