As I dig deeper into the left hand side that I have apart, the more I realize that there’s been some damage and repairs in the past. The front Wheel pivot arm Had been broken and welded at some point, and the ears that attach to the spring in can link bar appear to be homemade as the profiles don’t match that well. One of the link bars had also been cut off and a new hole drilled in it. Between that and the twisted walking beam I decided to take apart the other side to hopefully have some good original parts to compare to.

I removed to other track and luckly everything on that side Appears to not have been Damaged and messed with. Walking beam is straight, front pivot arm is good, and the link bars are the original length. I think the spring in can has been redone at something but everything else looks straight. Only worn part appears to be the walking beam pivot shaft like the other side so it looks like I’ll be attempting to remove that shaft ?.

I’ve also cut apart the left side spring in can. I have a piece of 5” spouting that will work perfect. Not sure if I’ll try to salvage the end caps or make new ones. I thought I read somewhere on this site that the spring should be slightly preloaded in the can. Mine didn’t appear that way. My spring is also a couple inches shorter than the can itself. Does anyone have the original dimensions? Ill cut the other side apart to compare and at the very least make them both the same with the number I have.

In this pic you can also see the weld toward the shaft end of my front wheel pivot arm. The bearing housing of that is also worn through and had a patch welded on it, which I removed. Worse case I’ll machine a new bearing housing, but I might be able to patch it up.

Not too much to report. I cut the welds on the one half of the walking beam that is twisted and started to straighten it out but not done yet. The other walking beam assembly is all cleaned up and ready for paint. I also cut the other spring can apart and the spring by a quick comparison looks to be the same length as the other side. I’ll confirm this and make both new cans the same.

A quick question regarding the spring in cans. Both had a piece of tubing floating on the rods inside the spring. We’re these originally welded to the end cap with the hole in it to act as a guide for the rod? Or were they attached to the plate on the end of the spring that the rod attaches to? Mine are both so worn that it’s hard to tell. I’ll probably make new ends for the can anyways, but I’ll attach the tube where it should be in the process.

Thanks in advance!

Yes.
Drilling the belting is a pain.

Use a "Brad point" type bit and it will cut it right through.....(Just don't hit metal with the bit)
One of these bits will gitterdone quickly......Makes a very clean cut

Ya I have used those bits before but never on rubber this thick. Perhaps I’ll try drilling a couple holes with one of these and compare with the hollow drill.

The pipe (stop) is welded to the end plate of the can, where the rod hole is . Keep the pics coming.:hammer:

10 4! Thanks. I have made new stops up and I’ll be sure to weld them to the end caps. I have new cans cut and the stops, just need to make new ends and then I can assemble the new assemblies. I’ll get some pics coming too as I know you guys like pics ?

Links cleaned up. I pressed out the bushings and am trying to decide what I’m going to make the new bushings out of. Some of the inner bushings were so seized in there that the arbor press wouldn’t do so I had to use the big hydraulic press at work. No wonder the bolts were so worn.

Some progress. I have a bunch of parts prepped and will hopefully have some fresh assembled spring in cans and new link mounts on the one front control arm.

Question, does anyone else have a grease nipple on their cans? My old cans have one on the front end, but that’s kind of in no mans land and You’d have to put at lease two tubes of grease in before any gets to the spring. My plan is to liberally coat the springs and can before assembly, but not sure if that’s the correct location for a nipple.

It would be ideal to get a nipple with a line routed into the stop pipe somehow, so any excess grease either comes out or goes into the can, but I will likely end up putting the nipple around half way up the can so the grease ends up on the spring.

Never saw one with that, but you may be on to something. A small drain hole, in the bottom is what I usually have and pump some grease in, when in for a service.
