Replacing The Hydrostatic Steering Hoses - Zetor 86 41 forterra turbo Operator's Manual

REPLACING THE HYDROSTATIC STEERING HOSES

The hoses shall be replaced four years after the date of their manufacture (that date
being specified at their surfaces) or after 3 600 hours of tractor operation. Or –in
case of detecting any symptoms of their damage (hose dew, local bulge, leak of
service liquid around the ends, surface permeability, damage of their covering due to
the mechanical abrasion with the metallic chassis, damage to the yarn braid in case
of low pressure hoses.
in the event of the pump failure or when the engine is at rest the steering
ability is kept, but the effort to be applied to the steering wheel is much
higher. The tractor may move – at lower speed – up to the nearest place of
repair.
The steering wheel may not be kept at the extreme positions for a longer pe-
riod of time (maximum interval being 20 sec.). Otherwise excessive heating
of oil takes place in the hydrostatic steering system.
