Maintenance
SUMP PREHEATERS
Preheat the transmission fluid to the minimum temperature for the oil viscosity used before engine start up.
NORMAL OIL CHANGE INTERVAL
Drain and refill system every 1000 hours for average environmental and duty cycle conditions. Severe or
sustained high operating temperature or very dusty atmospheric conditions will result in accelerated
deterioration or contamination. Judgement must be used to determine the required change intervals for
extreme conditions.
EXTENDED OIL CHANGE INTERVAL
Extended oil service life may result when using synthetic fluids. Appropriate change intervals should be
determined for each transmission by measuring oil oxidation and wear metals, over time, to determine a
baseline. Wear metal analysis can provide useful information but a transmission should not be removed from
service based solely on this analysis.
FILTERS
Service oil filters element every 1000 hours under normal environmental and duty cycle conditions.
