The Stovebolt Site Forums The Shop Area Driveline Clutch Size

I need to rebuild the clutch in my 1950 3100. The engine is a '56 235. The transmission is a standard 1950 3-speed with the serial number H0206273.

Can anyone tell me the size of the clutch?
Or how to determine the size?
A reliable source for replacement parts?

Thanks,
Deron

Deron,

You might have an older clutch assembly (to match the 1950 assembly) or a later clutch assembly (to match the 1956 assembly).

Is you truck 6v or 12v?
Is your starter 6v or 12v?

I think you should pull the transmission and then remove the clutch assembly (keep the the throwout/release bearing). Buy an entire clutch assembly to match what you find.

Measure the OD of the disc, that will tell you what size.

The truck including starter is 12 volt.

I was trying to avoid pulling it apart before I have the parts in hand. This would reduce time in the shop.

Also, I would appreciate suggestions for sources of replacement parts.

Thanks,

I would go ahead and pull it apart, most suppliers can ship fast, nothing more frustrating than finding parts don't fit, since this is not modern stuff. Besides, you might find something else needs attention while it is apart.

I'm asking this question because I have a 49-3100 with a 55-235 and a closed drive shaft that also needs a clutch replacement.
Do to closed drive shaft,I'm not sure I can remove clutch/transmission without moving rear end or removing engine.
Not sure what you have for drive shaft but where you able to just remove your clutch/transmission?
Thanks for any info.

Loosen the bell assembly and slide it back,then loosen the u-joint and slide it back,at the same time push the d/shaft tube up and tie off with a rope.you may want to have the rope in place before undoing. U-joint. That will make room for the Trans to slide towards the rear of truck when you take it out.

Doug,

I have the same set-up as you. I have not removed the transmission, but the service manual basically gives the same instructions as Quindel54. I have replaced the gaskets for the u-joint enclosure and it was not that bad.

I plan on attacking the clutch disassembly this weekend. I will post an update later.

I have a 2x4 the width of the insides of the frame rails behind the transmission.
I push up the torque tube and place the 2x4 under it, between the frame rails.

This is safe and easy.

I got the clutch out and determined it is 9-1/8". Where would the best place to buy a replacement?

** Your best bet for a complete clutch kit will probably be Rock Auto. They have the complete standard kit for $83.00.**

Update. I got the clutch assembly out and purchased a new kit from Classic Chevy. The biggest problem was getting out the pilot bushing. After two (2) hours of messing with a pilot bushing puller, I went to Mr. Google which lead me to Youtube. Found aq video using bread to drive out the bushing. And wouldn't you know it...it worked. bushing was out in less than 5 minutes. Here is the link

Got everything cleaned up and installed the new pilot bearing and clutch. Next will be the transmission and get it back on the road.

Grease works just as well, won't infuriate kitchen help.

I've never been able to get grease to work on a pilot bearing. It just squirts everywhere. It may work on a bushing. But canned biscuit dough works well. And you can bake the remainder of the biscuits.
