100c not moving under load

Pcdtodd100c · Oct 24, 2023

I have a 100c we got it was pretty rough. We repacked all the cylinders as well as track tensioners. Changed all fluids filters and screens. It is a power shift transmission. Runs. Great. The issue is when bushing half a bucket or more the transmission disengages. Shift to neutral back to first it will gradually start to pull but may disengage as it gets hotter the worse it gets. Main hydraulic pressure is within limits. Have a service Manuel but don't know where to start. Regulator valve, pump, torque converter. Any help would be appreciated

Pressure test, usually when a power shift jumps into neutral it is because there is not enough pressure to hold it in.

Where do I check the torque converter and pump pressure? I can't find in the service Manuel. We checked one pressure a 160 or 165. But says the torque converter operates at 90psi but does not say where to check it.

I can't remember where the pressure points are, go over to the IH site Red Power at the link below.

Is there a way I can send a video of what it is doing. I think it's a pressure issue. Weak pump or valve. But I really am just guessing.

You can post a video on here, go down below the message panel, and you will see post pictures or videos and take it from there, you can also post on utube and put the link on here.

This is it running gauges are good. Continues to push once warm tracks stop. Shift out of gear back into gear track will gradually start to spin. Drive shaft never stop. Engine speed doesn't change.

I have attached the YouTube link

Thanks. I uploaded a YouTube link. But today I checked pressures. Main pressure is within limits as is the lubrication part.

The torque converter pressure is way off over 230psi in neutral. 125psi in gear. Should be between 40 to 80psi. What controls this pressure and how to get this pressure within limits.

I cannot remember any details on a machine that age as I have worked on dozens of other brands since that machine was popular, The guys at Red Power will be able to help you out as they are quite a few posts on there about similar problems.
