Cat d6c power shift

Hello gordo, your shift symptoms are most likely caused by worn shift linkage. The spherical rod ends on the linkage are a good place to start. There are also bushings on the shift arm shafts that might be worn.
A service manual would save time and money; they are often available on ebay or in the For Sale/Wanted section here.

I don't think it's always necessarily the linkage to blame? On my D6C the spacing between forward and reverse is fine when it's cold. As the transmission gets up to a good working temp I find neutral gets hard to find, as in when I shift out of first forward it pretty much goes straight into reverse. If I want neutral I have to wiggle it around a bit. But like I say, when it's cold it's perfectly normal. I've just been ignoring it for years 😊

Gordo,

Its only worn linkages and adjustment, best to replace worn parts and get it working properly, as you have no modulation on your direction clutches and will damage the transmission going directly from forward to reverse. I have known as a very short term solution to adjust so that you do get neutral and possibly lockout 3rd gear as a result, I would only do this as an emergency until you get all the parts, link ends and control shafts, bushes and dust seals, these parts are not expensive, heaps cheaper than a transmission failure. Modulation is only by the speed clutches.

Thanks for the comments... Should I go to my local car dealer for the parts?

Gordo,

I go to my local milkbar if I want a double malted milkshake, the parts you need I recommend you go to your local Caterpillar dealer.

Con mi amable respectos, Senor Wombat

Hi Gordo, yes your Cat dealer likely has the parts. I always try my Cat dealer first on the basis that if I buy from Cat, they'll see the movement in the stock and (hopefully) keep them in inventory
