E. BEARINGS
Bearings which are considered suitable for further service
should be cleaned in a suitable solvent and immersed in
clean lubricating oil until required.
Installation of a bearing can be classified into two (2)
ways:
press fit on rotating parts such as shafts and gears,
push fit into static locations such as reduction gear
houses.
Where possible, always install the bearing onto the
rotating components first. Use the correct tools or a press
to install a bearing or bushing. In the absence of the
correct tools or press, heat the bearing and / or casing in
hot oil to assist the installation of the bearing.
When bearings or bushings are removed, always carefully
check that the bearing is free from discoloration and signs
of overheating. Also check for mechanical damage such
as excessive clearance, nicks and scuffing. If in doubt,
replace the bearings or bushings.
Bearings should never be removed unless absolutely
necessary. Always use the recommended puller to reduce
the risk of bearing or related component failure.
These bearings and bushings are subjected, in normal
operation, to high working loads and adverse conditions.
Be sure during normal routine servicing, maintenance or
repair that bearings are given the right attention and are
installed with care.
F. BOOM SUPPORTS
For safety while performing regular service or
maintenance work, the loader is equipped with boom
supports.
The boom supports, when extended, prevent the boom
arms from dropping if hydraulic pressure is relieved or
the foot control pedals are accidentally cycled.
To operate the boom supports, first remove any bucket or
attachment from the quick - tach; raise the boom arms to
full height and shut off the engine. Raise the boom
handles up and push out toward the boom arms to extend
the boom supports.
WARNING
To avoid personal injury, service the loader with the
arms down and the bucket or attachment on the
ground. If it is necessary to service the loader with
the boom arms raised be sure to engage the boom
supports. Never work under or around a loader with
raised boom arms without boom supports engaged.
