Trouble, symptoms Remedy
Seizure of the overflow valve in the distrib-
uting filter.
Flush the distributing filter valve.
No pressure in the hydraulic system of the transmission
The drive of the hydraulic system pump is
OFF.
Turn the pump ON.
Lack of oil in the transmission housing. Add oil to the “ П” (Full) mark.
Excessive noise when shifting gears
The clutch fails to disengage fully (the
clutch “drags”).
Adjust the clutch.

Increased pedal travel. Perform the adjustment as describes in
Section “Construction and Operation of
Tractor Components”, item “Adjusting the
Brakes”.
Air inleakage into the hydraulic actuator
system due to drop in brake fluid level in the
master cylinder reservoirs below the mark
“Min”.
