Some advice for speedy and correct repair
work
– Mark machine parts prior to disassembly to
ensure their correct left-to-right positions and bal-
ance when reassembled.
– Fit expansion pins with the slot facing the side
under load. When fitted with a
quarter
turn from
this position, they will get loose, fall out or shear
off.
– Replace split pins, locking wires, locking plates,
tab washers and lock washers when carrying out
repairs.
– Install greasable ball and sliding bearings with the
grease specified for them.
– Align sprockets and V-belt pulleys toward each
other.
– Care for strict cleanliness when working on
hydraulic systems.
– Never mix different oil types.
– Run the machine or operate machine assemblies
at low speed after any repair.
