jerryt Posted January 23, 2022 Report Share Posted January 23, 2022 I am taking off my clutch master cylinder. The master cylinder unbolted but there is a problem. The pushrod is held by a pin that has a lip on it and won’t come off. Also there is no c clip on master cylinder. Should I cut this pin and put a bolt on it when I put everything back together?

Ooph! Posted January 23, 2022 Report Share Posted January 23, 2022 Pin is part of the pedal? I would try a small file to knock down the edge and be patient Quote Link to comment
jerryt Posted January 23, 2022 Author Report Share Posted January 23, 2022 pin goes tru the pedal.. There is a u shaped part at the end of clutch master cylinder. Then the u shape goes around pedal and pin or bolt keeps clutch push rod connected to pedal. Jerry Quote Link to comment
datzenmike Posted January 23, 2022 Report Share Posted January 23, 2022 The threaded push rod should have a clevis on the end. (the U shaped part) That's the clevis pin that goes through the pedal. The hole you see is for the cotter pin to keep the clevis pin from falling out. The clevis pin should just push out to the right Quote Link to comment
jerryt Posted January 23, 2022 Author Report Share Posted January 23, 2022 It’s a Frankenstein car. I thought like you the pin goes thru the clevis. I pulled the cotter pin and tried to the pin out. But I think the pin has a mushroom topaz’s won’t come out. So do you think I should cut the pin? Quote Link to comment
jerryt Posted January 23, 2022 Author Report Share Posted January 23, 2022 Or here’s a thought cut off the mushroom end. thank jerry Quote Link to comment
thisismatt Posted January 23, 2022 Report Share Posted January 23, 2022 File it enough to get it to slide out. Quote Link to comment
datzenmike Posted January 23, 2022 Report Share Posted January 23, 2022 If deformed maybe it's just wear. Will it wiggle out? How would it be installed??? better yet how did it get that way??? Hardly seems likely that someone peened it over while in the car. Quote Link to comment
jerryt Posted January 27, 2022 Author Report Share Posted January 27, 2022 Well I just checked it on both ends as it went thru clevis. It was mushroom on both ends. I agree with you why would someone do this? So I cut it off with a sawzall. I took the offending part and couldn’t figure it out. So I took hardline and screwed it into master. I know I have to bleed it but just wanted to see. The new master has inlet on side in the front. The old one had inlet on the top front. I just had to bend hardware a little. So how do I bolt clevis to pedal? Do I let out rod until it just bolts up to the pedal? thanks jerry Quote Link to comment
datzenmike Posted January 27, 2022 Report Share Posted January 27, 2022 Pin should go through the the clevis with the pedal in between and stick out the far side. The hole is for the cotter pin so the pin can't fall out. I don't think this it the stock part. Quote Link to comment
Stoffregen Motorsports Posted January 27, 2022 Report Share Posted January 27, 2022 You can get generic un-threaded pins at any hardware store. Some have a single split pin hole and others have multiple holes. You can cut the long ones with multiple holes to length. Don't use a bolt. That's hack. Quote Link to comment
Stoffregen Motorsports Posted January 27, 2022 Report Share Posted January 27, 2022 Look here for all the different types of clevis pins - https://www.mcmaster.com/pin-fasteners/ 1 Quote Link to comment
jerryt Posted January 28, 2022 Author Report Share Posted January 28, 2022 Ok I will look for a pin and not use a bolt 😳. The motor and transmission are Datsun. I am going to mock up the clutch master and see how far the hole for pedal and clevis and adjust rod accordingly. I still have to put slave cylinder on so it should be fun. Thanks jerry 1 Quote Link to comment
