Transmission Shift Fork Pins
Hi Everyone, What is a good method for backing up the head of the shifting fork pins for upsetting the hollow head. So far I have tried various chisels, screwdrivers and chunks of steel only to find that I need six hands and more patience. Also after they are upset it appears that they would still be loose. Is that right. I've heard a few people say to use roll pins, but I want to do it the way Henry did it.
Thanks for your help, Dave |

Hi Dave,
I have been there a few times with success, but find the roll pins a better option, do not remember the size.

Re: Transmission Shift Fork Pins
I did it the first time with rivets, but they never would tighten up...always a little movement in the shift forks.
I made a bucking tool that held the heads and fit tightly in the case, but it seemed the available rivets did not have a deep enough recess in the end to allow them to tighten properly. I used the roll pins the second time when I changed to a front mount brake handle. Much better.. .

Re: Transmission Shift Fork Pins
I just finished this job last week. I took a pair of Crescent brand slip joint pliars and adjusted them so they clamped against the head of the rivet and the opposite side of the fork, with the handles almost closed. I then clamped the handles together with a pair of vice grips and used a hammer and large center punch to spread the end of the rivet. Worked like a charm.
Old combat adage: if it looks stupid, but it works, it's not stupid!

Re: Transmission Shift Fork Pins
Hardened split pins (sometimes called roll pins) work the best. Easy to install and a tight fitting fork when done.

Thanks everyone, I'm switching to 3/16" X 1-7/8" roll pins. |

Re: Transmission Shift Fork Pins
I decided on roll pins. Not 100% comfortable with that, I ran safety wire through the roll pins and around the fork shaft. They weren't going anywhere.

Re: Transmission Shift Fork Pins
Russ,
I did the same thing. I took a dermal tool and made a groove on the opposite side of the split in the pin for the safety wire to lie in. |
