Cat D7E Dozer

Cat D7E dozer serial# 48A8929. All fluids are good. When you throttle it up the motor sounds like it’s under a load, the machine starts to creep forward with it in neutral little smoke coming from under feet, the smell is not motor oil burning I don’t know how to describe the smell. The park brake is off floor paddles fill fine. I don’t know if a brake isn’t releasing. I took back covers off where shaft is hooked to the brake rod and it looks like they are releasing.

Sounds like the shifter linkage is mis-adjusted.

Found a vid of that machine and there is something wrong with that engine anyway. It seems to struggle to turn and blowing white smoke.

Creeping forward could be a very large concern. You need to ensure the torque converter temp gauge works and the trans pressure gauge. There is a suction screen filter filter between trans and trans pump on right side of machine just above the track and below the operator platform. that is where I would start.

Do not let the machine creep. That is not normal and you could have partially engaged clutch frictions which could be smoking, thus the odd smell.

I’ll check out the screen let u know if that solves the problem.

Does anybody have a service tech manual for a cat D7E dozer serial# 48A8929
