CK20 Throttle Problems - VIDEO - Please Help

[DK35vince]

Thanks for the info guys! I am going out of town tomorrow for a few days, but I will take photos when I get back. I looked at the fuel filter tonight (its in a clear plastic housing on the back side of the tractor), and when looking through the plastic, it looks like the filter is crushed or something? It just doesn't look correct. Hopefully if I post the photos you guys will be able to tell if it's worth trying to replace the filter first. Hoping this will be an easy fix!

I can tell you the first thing I would try is replacing the filter without even seeing a photo.

I had this same problem and started with the filter replacement (and my old one looked crushed as well), but my problem with this was that the bend in the fuel plumbing around the shutoff, the fuel was just trickling out, I cleaned the best I could from the bottom with a thin wire and got it to flow better, though probably not a as fast as it needs, but for now it supplies enough fuel that it no longer slows down.

+1. Get and keep a spare on hand, especially for winter months. It's easy to change and can save a lot of headaches.

Exact same problem last week with my CK20, your video could have been mine! First thing I check was the fuel filter, I could barely see translucence iced particle in the fuel filter. I added anti freeze in the fuel tank, waited 30 minutes, but still the same problem. So I took it in the garage for three hours at 60F, plugged the block heater, and voilà no more problem! My fuel supplied was from this summer, perhaps not the good winter formula? Where was the gelling of the diesel occurred in the line? Don't know, but after an important cure of heat, it came back to life. For the rest of winter I will add systematically an anti diesel freeze.

Best of luck, it is cold out there!

As I understand it, wax crystals form in cold fuel and these can block the filters even when you can't see them. If you can warm the tractor, I'd try that first. If you start changing many things it's hard to know what fixed the problem or even if it's really fixed. The symptoms are classic for fuel starvation but the potential causes are many.

Couple of years ago, with mechanic we were installing a generator set (500Kw Caterpillar) in a train container, having the same problem (fuel depravation) one of the guy installed a temperature gauge with memory. The engine failed again during the night; we were blame again... But the low temperature was recorded -35C, and the fuel was supplied by the train Cie and supposedly certified for winter use... We dismounted the fuel line, and it look like maple syrup. We flush everything, order ourselves real "winter" fuel, no more problem. The filters where ok, the fuel pump also, it was the thickness of the fuel going through the fuel line (1/2 inches).

We took the container inside the train garage overnight, with adequate fuel additive no more problem...
