Replacing the hydrostatic steering hoses
F11N037
The hoses must be replaced after four years from the production date (the date is indicated on their surface)
or after 3500 hours of work of the tractor or immediately after discovering signs of their damage (hose
sweating, local buckling, leaks of the working media around the end pieces and on the hose surface,
abrasion of the hose surface to the metallic reinforcement, damage of the outer yarn braiding in the case of
low-pressure hoses).
In case of a pump failure or after stopping of the engine the steering capability is maintained,
but the required steering force gets higher. You can drive the tractor at a reduced speed to the
nearest workshop. The steering wheel must not be held in the limit turning angle positions for a long
time (the maximum time is 20 s); otherwise the oil in the hydrostatic steering circuit is heated up
excessively.
