The Stovebolt Site Forums The Shop Area Driveline 46 Burb Clutch linkage

G'morning,
I am having a time of trying to get the clutch linkage assembled and adjusted on my '46 Burb. Could someone shed some light for me. Or photos of how it is supposed to be. I think I may have an incorrect linkage rod. The one from the clutch pedal to the throw-out bearing arm. With what I have there is not enough adjustment to get the throw=out bearing to do its job?

Thanks for any help. I am in North Central Mass if anyone one is close enough so I could look at what is supposed to be.

Thanks, Ricard

Ricard, I do not have any personal knowledge on this subject, but you might wish to check out the 1942-1947 Chevy Shop Manual , supposedly covers cars and trucks. Check out page 6-53. Here's a link.

Richard,

Dusty53's reference provided is the link to the whole manual. If you click his link, then click on the 6-53 next to the word "Clutch" that gets you closer to the correct page.

The actual page in that manual with a kinda fuzzy picture of the truck clutch release linkage is on Page 6-57. See Figure# 121 and the short adjustment instruction above the picture (screenshot provided below).

A better picture of the clutch release linkage is found in Figure 115 in the 1941 Shop Manual from the same resource site as Dusty53's reference (2nd screenshot provided below).

Both manuals have almost the same picture and parts configuration, so it should provide you (hopefully) what you need to solve the problem. NOTE: The only real difference is the change from '41 to '42-'47 with the earlier "adjustment nut" that was pushing the clutch release arm away from the clutch pedal, changed to a "jamb" nut in the '42-'47 configuration (adjuster nut with a stop nut to retain the adjustment setting) which then leaves more threads on the connecting link to adjust it's length for clutch pedal free travel setting.

Let us know what you figure out and ask more questions if still not enough info.

Aha!
Thank you all so kindly. I now see the issue or should I say, my problem. I have linkage for passenger cars not for trucks. Now I shall need to find the shorter adjusting rod with the hook on the end. Or make one. Do ya know the length? Probably play with it some.

Thanks again,
Richard

That looks like a hook you can buy at Home Depot or any hardware store.

Bolter from Atlanta, You have an interesting name, are you related?

And yes, I hope to find one this morning.

Richard,

Here is what may be some helpful info from one of the available online Parts reference resources for your '46 clutch linkage parts.

Screenshot below is extracted for easier viewing. The red arrow indicates the correct adjusting bolt (including dimensions) as GM# 598342. The green arrow indicates the normal tension return spring. The blue arrow indicates the "extra" tension stength return spring that was available if the regular spring wasn't up to the task. I made mention of the different return springs in case the one you currently have is also the non-truck item like your adjuster.

If you were to fabricate a replacement adjuster, you should probably be able to duplicate the "hook" end from the part you have and just get it to the specified length of the adjuster to meet your needs.

Good luck and hope you will return and show us what you were able to come up with.

Dan

Otto makes a good point on the hook. Might have to re-form or open up the hook end, but that's a good place to start and should make it easier to do a fab.

If you need the "spring" the part number 368244 (info provided by Dan) is available from Dan's Obsolete Gm Parts in Chinook Mt, call 406-357-2615. Record shows he has 11 in stock. I've done business with him several times. Good people.

Best wishes.

Ronnie
