Today I had the push rod pop off the clutch pedal, I'm guessing that while I was fishing the wire harness out the other day I must have knocked the keeper clip off.
I went to put the push for back on and noticed it is extremely worn so I have ordered a new master cylinder to get the push rod.

The pin that the rod rides on is worn pretty close to half way thru it. I'm sure that my old jalopy is not the first to have done this.

Is there a replacement pin available, or could a guy fill weld the worn spot and smooth the pin out well enough to allow the push rod to work properly with out binding up?

As always thanks in advance. Landen

I've never seen one worn that bad.

Part number for the pin is 4019420. NLA I'd bet Oliver Foster has one.

Clip is #4294036. Dealer made me buy a bag of 10. I have 2 trucks. You do the math.

I would imagine any solid pin and retainer the right diameter would work.

I've seen a few pics in threads of worn pins, and rod ends....welding it up and then re-shaping it would work I'm sure.

Thanks for the numbers, I had a feeling the pin would be NLA. I haven't seen them worn like mine is either. If I had realized it was that bad it would have been a bigger priority before now.


I'll have to grab some pics of this when I replace it. Guess I'll be waiting for the master to get here and then try to find a pin the same diameter, just in case the weld and grind won't work.

So I finally got to this clutch pedal issue, got the pedal out. This is what I have to deal with.





I came up with an idea using pins and bushings, that I found at Home Depot and a farm and ranch store.









The two larger sleaves have a set screw to hold it all together. After putting it in and sliding the old master back on for a couple test pushes on the pedal, The pin is solid and does not flex any when depressed. I think it will work.

That is a pretty sweet fix!

Okay, I have had a LOT of manual 1st gen pedals in my hands, and that is the most worn looking pin I have ever seen.
Nice looking fix

Thanks guys, I only hope it works as good as it looks. I just realized I forgot to post the master cylinder side, it looks just as bad.

I made one with a 3/8" rod end for mine. now both my clutch and brake pedals are adjustable.

I am contemplating doing the same thing, as I've tried three different masters that are supposedly for our trucks today and none of them had the correct pushrod. They were all way to long.

Had oreilly cross the dodge number on mine they say it's for a 92-94 Dakota. It will be here Tuesday. If that one is incorrect still, I'll have to fashion a new rod end.

that's one of the reasons I went to a GM hydroboost. I See sooo many people having master cylinder problems with these trucks.

Not only solid, but adjustable.

Mine came out real solid.

you are in good shape for the next 120 years

Hydroboost is on the list of want to do's. Because I know it's only a matter of time before I have brake master/booster problems.
