PROCEDURE
CAPABLE IF:
CAUTION
The drum drive gear reducer and the propel gearboxes generate
a large amount of contaminants during the first 250 hours of
operation. Oil sample taken from the gearboxes will generally
show a high iron PPM count. This initial break-in wear is con-
sidered normal.
If the initial 250 hour oil change is not done, these contaminant
particles will cause accelerated wear and can reduce the service
life of the gearbox.
Make every effort to complete the initial 250 hour, and 1000
hour, gearbox oil changes to the rollers listed above.
If the gearbox oil is changed before the initial 250 hour interval,
the oil should be sampled and changed again at 250 hours.
