Reassembly of the air cleaner elements
Carry out a reverse procedure in order to mount air filter
cartridges back on.
While mounting the cartridges back on mind:
- The cleanness of contact surfaces
- That the cartridges must not lose their shape while being
mounted and they must not vibrate after their mounting
has been finished
- That after having closed the filter with the cover you must
ensure a perfect tightness of the entire filter
When reassembling the air cleaner cover, keep its proper position in accordance with the
figure!
Replacing the hoses of hydrostatic steering
Hoses need to be replaced four years from the date of their manufacture (date is given on their surface) or
after working 3,500 hours with tractor, or right after learning the symptoms of their damage (hose, local
swelling, penetration of working medium around endpoints and hose surface, wrapping damage by
mechanical smear to a metallic body, damage to external buckle braid with low-pressure hoses).
If a pump gets damaged or if the engine is at standstill, steerability is observed, but the force
on the steering wheel increases. It is possible to get to the nearest place where repairs can be done
with lowered speed. The steering wheel must not be held in the positions of extreme wheel locks for
longn (maximum time is 20 sec.), otherwise there is excessive oil heating in hydrostatic steering
circuit.
Bleeding the hydraulic circuit of the hydrostatic steering
1 - Start the engine and let it run at the idle speed for
approx. 1 minute.
2 - Turn the steering wheel several times to both the sides
at the idle speed of the engine.
3 - At the maximum engine speed turn the wheels with the
steering wheel 3 times alternately slowly and quickly to
both the sides up to the limiting stops of the wheels.
4 - Stop the engine and lower the tractor onto the front
wheels.
