A Better Clutch Adjustment Page

Post by Steve Jelf » Sat Jul 06, 2019 5:56 pm

When the subject of clutch adjustment comes up, often somebody will post Murray Fahnestock's article and drawing. It's usually a bad copy, and often unreadable. So I've put a better copy on my website. If anybody asks you about the subject you can refer them to this.

That's a good picture of the document. Also has a few more details.

Thanks Steve for posting a clearer photo of the instructions. Before I do any of that fine tuning I remove the transmission
inspection cover and confirm that the clutch is set at 13/16” or the spring is compressed to 2” and ideally the three finger adjusting screws are well and truely backed off indicating the plates are serviceable.

Thanks so much for doing this. It's coming at a perfect time as I will soon be setting my pedals and linkages. Wish me luck!

Tim

As a FYI, while doing the clutch adjustment, do not be surprised if the clevis needs to "grow" in length, and do not be surprised if you are at the tip-end of adjustment when you're done. This is a very common issue that is left undone by a great majority of service persons.

I just got through putting a 40 year museum car back on the road. It had recieved a fresh engine and a transmission refurbishment prior to display. The transmission was thoroughly out of whack and I needed to make and install a new threaded "L" portion of the clevis assembly that was 1/2 - 5/8" longer than stock. This is one of the most misunderstood and overlooked parts of the entire assembly. Also, after extension and adjustment, you do NOT want the assembly to have only 3-4 threads engaged...you want minimum 1 1/2 diameter of threads down in the "U" portion of the clevis before the jam nut is tightened. This will determine how much longer you need to make the replacement, if you need a replacement.

This is one of those simple supplier parts that would sell if only people who need them understood that they did...
