Powerman5K Posted August 2, 2022 Author Share Posted August 2, 2022 Me 3 on checking the linkage and dont just look at it pull it apart. Remove the rod from the arm at the pedal and look over that end of the rod & arm to make sure they are round. There should also be a thin plastic bushing that fits over the rod before going thru the arm and the pin back in. At the other end of that rod do the same pull it and look it over the same way. There is also a bushing here too. Unbolt the frame pivot for the Zbar or cross shaft and remove the povit and cross shaft. IIRC there are pins you need to pull on the shaft before it can come off the motor side pivot. There should be plastic bushings on both the the frame & motor side pivots. They are held in place with half round spring clips before the bushings can be removed from the pivots. There should also be felt seals that fit on the pivots before the bushings are installed. Make sure all bushings are in good shape. On the Zbar / cross shaft when going back together pack grease in the ends and around the pivots and after you get the frame pivot bolted down push the felt seals into the Zbar / cross shaft. If the Zbar / cross shaft bushings are not kept in good shape they can cock the Zbar / cross shaft and put strain on the motor side screw in pivot and could snap it! You can not get this screw in pivot for the 300 six motor any more. The last one posted from Ebay was $170 IIRC Dont ask how I know all this BTW my pedal was doing the same thing for about 2 weeks before the motor side pivot broke off the motor. I was lucky it happened 1/4 mile from my house and I had a new pivot because I had fixed this one 2 times before. Also when I put the truck on the road 2 years before it had now thin bushings, they were trashed when I pulled it apart for this last fix. I hit the hardware store for thicker bushings in hope they will last longer than 2 years. This is how I got the truck Dave ---- Just got mine off this morning and this is where I'm at. Not as bad as yours but I want to fix it. Obviously the factory bushings are none existent. I looked to replace the rod all together and just like everything else that goes bad on these trucks, they don't make it. Ebay has some for $90... pass. So what are my options? I'm thinking of going to my local hardware store to find some brash bushings to get everything back running proper. Any thoughts? Link to comment Share on other sites More sharing options...

On Dad's truck I welded the worn bits up and ground them back to round. Or used a drill to make the hole the right size. But speaking of size for the holes, since I also bought oilite bushings that are bigger than the plastic bushings I drilled the holes out to take the oilite bushings and used them instead of plastic. I don't remember where I got mine, but Amazon has several. Link to comment Share on other sites More sharing options...

FuzzFace2 Posted August 3, 2022 Share Posted August 3, 2022 I was able to find a brass bushing at my local hardware store. Thanks! Looks like you got it in time I would have loved to go a bushing like that but the local store did not have anything close that would work The only thing I was worried of when making the holes a little larger for the bushings is not having enough "meat" around the hole for support and making it weak. I figured if I found it was to thin and weak I would run a bead or 3 down the edge with the welder to build it up thicker but looked OK so did not weld beads. A really good fix would be Hyme Joints as you would never have metal to metal parts rubbing together that should not be. Heck I did not think of it till just now and if I have issues again that will be the way I go. I have a second rod so maybe I should start looking into this?

Dave ---- I think Heim joints would be a good solution for the mechanical linkage. Link to comment Share on other sites More sharing options...
