how to split track ???

Hi Mate , It depends what type of joiner you have . The newer type use the bolts through the track plates and through the 2 halfs of the link . .Other than that some have retaining pins holding the master pin in ,or the d2s had tapered plugs to remove first . All as far as i am aware are then driven out with a big hammer .

it seems some of these rails do not have a pin that looks any different than any others. I have looked inside and outside all of them look the same...so i just pick one and hit it HARD.?? my recolection from years back was it took a lot of hammering and maybe some heat. is this still true today?? Hate to heat or ruin a sealed pin. this is on a d69u.

Sounds like you have a Heinz variety of tracks....are any of them worth saving...if not just torch through the links and be done with it.
If you have to dismantle, the threaded expansion plugs need to be removed. You need to find the master pins as they have the shorter bushings that allow uncoupling the link....some just have a dimple on the end to identify them, some have a hole, some have nothing to identify them with and require fishing with a hacksaw blade to find the pin with the shorter bushing. You can heat the sealed track but not a good idea with sealed and lubricated.

A pin pusher with holder is handy if your using the big hammer method.

This info is from a later larger tractor but it shows how to deal with the sealed track pins.

he post before the last one is obviously a joke!!!!

thanks OM. Ya the old crap ones i will cut with the smoke wrench . the better ones are sealed and I found the master pins so probably have it under control ...for now anyway.👍

Hi Phildirt,
no OM was not joking. He posted a pic of his "improved" version of Caterpillar's tooling to hold a pin punch for one man operation in the field.
The scan below is from the D7 17A SRB.

If it's the hacksaw blade (feeler gauge) that got you going.....the tip came from someone on the BB and I have used it a couple of times (limited to non-sealed track though) and it works.

Jokes on you.
