Worn Undercarriage D4C 40A

Did the rep give you a figure for pin and bushing wear?

Hello juiceman, With only 15% rail height left the cost of new pins and bushings is too much to invest. I advise buying new track groups or at least rails. The labor cost to swap your existing pads to new rails might make track groups the better option.

Thanks for the responses everyone. Cat rep might of given me measurements, all I remember was heighth, the chains are pretty snaky to me. I run that side fairly tight and it doesn't seem to matter; one of these days I won't be so lucky and sling it out from underneath and fight it back on.
I will give Miller Track a call; didn't know if Ben DuBose track service in Yuba City was in business or not; any guesses on what aftermarket chains with a pad swap would cost? I don't want to do a full blown u/c just yet. Just trying to be practical. Thanks again!

You might want to put a Wanted add in the For Sale section. Might be a member with a used set of tracks for you that will last a few years. They pop up quite often there.

Had a set done some years ago, reasonable and pretty quick, dropped them off in the morning, done that afternoon.

Hey OldMagnet,

Can Juiceman take one link out each side without messing up timing on sprocket?

Its nothing to do with 'timing' on the sprocket, if the tracks are stretched enough to take a link out, continuing to use them will wreck the sprockets due to pitch mismatch, they will still come off as well. If there is only 15% left in the rails, the chains are probably worn out, that's why I asked for all the measurements. When I did CTS reports, I used to put all the figures down plus a couple of sentences of advice.

The 40A uses a 29 tooth (hunting tooth) sprocket so removing a link has no affect on timing other than a slight change in repeatability. Removing a link stretches the pitch and accelerates the wear but is typically done to run to destruction to get the last bit out of the undercarriage. Does nothing to compensate for snakey track due to pin and bushing wear.
