front axle pivot bushings

somethings not right here. the front end was extremely loose on the pivot shaft so i ordered 2 new bushings for it # 350758R1. the shaft measures 7/8 dia. and the split bushing just goes on it, opening the split slightly. the OD with it on the shaft is 1.012" but the bushings in the axles at the moment look to be 1.125 or so OD.

is there more than one bushing set? or has my axle tube been modified to accept a larger one.

any help would be appreciated. thanks

Art,

The ones I have replaced have required a bushing 1" OD x .875" ID x 1" long. I haven't seen one come with a split bushing, but I usually make my own replacements.

seems mine has been bored out to accept a larger bushing. how did you get the old ones out? a drift punch from the other side won't get enough purchase to be effective.

Art,

Make or find a washer the size of the inside of the tube. Grind two opposite sides enough for it to go in through the bushing. Shove it in and allow it to flop over. Then you have something to work against with a rod... maybe even the pivot pin.

yup. sounds like that will work perfectly... except for an unforseen circumstance. the previous mechanic saw fit to simply (it appears) drive the old bushing to the center while installing the new one. so i don't have a lip to work with.
going to take it down to Dad's this afternoon. it's his birthday tomorrow (ground hog day, he's 72). perhaps we can set it up in his lathe and drill out the old bushing.

plus, one side has a larger bushing installed.

thanks for the help, i'll post the results later

Art, If you have access you can run a large tap into the bushing (say 1" coarse thread) Then use abolt threaded into the bushin with a sleeve slightly larger than the bushing as a spacer. It will pull it out slick as can be.

Success! no tap as large as 1" so that was out, but an idea to remember. tried to drill it out on the lathe but centering, as i suspected, was a problem. we did get in an 1/8", enough to see that the bushing was the correct size, the end had been peened over enough to look like it was a larger diameter. Had me fooled.

realizing that the existing bushing was of the split type like the new one, :idea: we then took a chisel (muffler cutter type) and curled in the bushing at the split. took both out in 30 seconds!

the center still seemed to either have an old bushing or was part of the tube, but it did not want to drive out. since it was not interferring with the bushings or getting grease in on the shaft, we abandoned attempts to remove it.

ready for primer and reassembly.

thanks for the assistance

Art,

All is well. The tube is bored out only deep enough for the bushing. The lip is natural, and keeps the bushing from going in too far. Do you have the washer(s) that eliminate end play? The "mushroomed" bushing make me wonder if there was one eliminated at the last repair.

there was one on each end, but i was thinking the same thing. i'll bet when i reassemble it i will need an additional washer.
