I am installing new pedal cams and the low speed notch pin fits snug but not tight,everything is new, shaft, notch and cam, how do you set the pin in the notch?, i was planning on using Loctite to hold it from slipping and then bucking it and peen the end, should this be done cold or heated.
I have the engine and transmission as well as the service manual and this is not discussed in any of them.Any suggestions are appreciated.
Cold peen both ends, Bob
I use a piece of a rail road rail, but anything would work to buck a rivet. 1/4" round steel rod about 1.300" in length. Peen over one side, flip the hogs head over and do the same. Takes a couple of flips striking each side to set. Installed cold.
Some will use a roll pin, not my choice but.........
Mike is right on about not using a roll pin in that application... they can and do break!
Been there, done that, never again.
Mike, thanks a piece of RR track is just right to buck with, a couple of hits on one side sets it good and then finish with the other side, quick and effective.
When replacing mine, I thought about using a grade 8 bolt and staking the end after threading a nut on it with Loc-tite; that is until I was informed by other forum posters that I was putting lives in danger by doing so. So I used the solid steel pin and can now sleep at night.
If you are going to use railroad rail for a bucking piece please be sure to check the train schedule before getting too involved in your work!
Excellent use for a piece of rail, Mike !
Rick My train of thought has left the station
I am going to open a can of worms, the pin is soft and it's only peened over on the ends. I know at least one person that has used a bolt for years and never had a problem. May be someone could re explain why they think using a bolt is putting life in danger. I have used a rolled pin in one of my clutch forks for years, did add a safety wire, and it is tight on the shaft.
Mark - Here's the thread I posted last year regarding replacing the pin with a bolt.
I believe by peening both ends, that action would actually shorten the pin forcing it to swell inside the hole cavity in the shaft and notch.
I don't know about putting life in danger, that might be a bit of an exaggeration. Suffice to say installing a rivet is within the means of anyone who owns two hammers, and is the best answer.
I clamp one hammer in the bench vise, and then am able to rest the transmission on the hammer in such a way that I can hit the rivet (made from a bolt) and swell the rivet in the hole. The peened over ends are not the main thing holding the rivet. The rivet swells in the hole so there is no slop.
