Machines | How to open up the track on a cat 235?
videos | at work | information | view | construction
I have this old Cat 235 excavator. I'm trying to figure out how to open up the track without buying the $6k Cat tool. I made my own hydraulic tool for removing the pins of the hydraulic rams. I suppose I could make my own tool for doing the pins but I was hoping there would be a better way..?

remove two pads next to each other and torch out the pin about 1'' deep without hitting the link. do both sides like that and the pin will come with a air hammer. install a new pin but loosen the holes slightly or sand down the pin diameter.weld around the pin to keep it there.thats what works for me!

I don't think you need to break the chain to rebuild the tensioner. Most of them just have four bolts holding the cylinder in place, pull it out, rebuild, reinstall. No big deal.

Nice movie. However you can make it yourself. Just google woodprix and learn how to do it easily.

Remove the entire track?

built a c clamp with a bottlejack on one side

A track adjuster seal is NOT a reason to take a machine out of service. Simply use a hand jack to get the front idler tight, (and subsequent track) then place a sufficient piece of steel jammed in place to hold it tight until you have other issues with the track. This will get you by until you have further issues and truly need to open up your track. Not being disrespectful, just wish to see you off and digging!

turn the track so the master pin is sitting in the sprocket teeth. look at the pin and make sure there are no welds holding it in. get a oxy/acetylene torch and heat the link around the pin and drive the pin out with a smaller diameter hardened steel pin and big sledgehammer. For track work you should have a torch set and a "Slide Sledge". I work alone and it works for me. Torch set might cost around 800 and another 300 or so for the slide sledge. cheaper than six grand.

i have the same problem, looking for the master pin and the same ring on the pin as you
did you manage to fix your problem, the bearings have gone on the front idler on ours
that looks like a paper wasp nest, if it is we have them here in Australia -
The old 235 looks good Bas, hope you are well. I remember talking to you on my phone about this 3 months ago or so. Search " track repair kimchiman1000" on youtube and look how its done on that Hitachi 200 shown in that video. Get a Cat 235 repair link from an aftermarket undercarriage supply company and just cut out the link whereever, just make the cut in the link at the 10 o clock position on the idler, so the links lay out easy for repair, and then you can slide out the idler and adjuster assembly.
