8” Brinly plow crank repair

Recommended Posts

Hopefully this is in the right area. I wanted to put this information out there because when I looked this info up I got no answers. 
 

So I purchased this 8” Brinly for a whopping $75. In general it was in good shape but the crank and trunion looked like they came off the titanic. They were seized together and I figured any attempt to move them would just disintegrate everything.

 

After a little research I was no closer to figuring out if new Brinly parts would fit an early model. Figured I’d take a chance and order a new trunion and crank from Brinly. I told myself I wasn’t going to try and fix it til after I broke ground on the new garden. Well my ADHD got the better of me and I started messing with it. Surprisingly all the components broke free and didn’t fall apart.

 

So the new handles are a slightly different shape and the threads are a bit long by about 3/4” compared to the old one. Threads are still 5/8-11 as the old ones were. The original trunnion was roughly 1.010. The new one was 1.051 so there’s two routes you can go. Make the mounting hole larger or turn the new trunnion down on either a lathe or a bench grinder. I went bench grinder since I don’t have access to a lathe or any friends with one. Worked out perfect. It’s not pretty but it’s 100% functional. 
 

So all in all, Brinly’s new parts can work with their older implements. I hope this helps someone else in the future.
