Dynapac Pneumatic tyred rollers, CP

Differential fluid capacity & service interval

Dynapac Pneumatic tyred rollers, CP differential fluid capacity ranges from 17,5 to 20 liters. Service intervals include checks at 1 month or 250 hours, and changes at 50 hours or 6 months or 1000 hours. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Dynapac CP221 and CP271, both fitted with the Cummins 4B-4.5C engine, share an identical rear differential fluid capacity of 17.5 liters, indicating a consistent drivetrain specification across those two models.
  • The CP275 with the Cummins 4BTAA 3.9 engine carries a rear differential fluid capacity of 20 liters, which is 2.5 liters greater than the capacity specified for the CP221 and CP271.
  • Across the CP221 and CP271 under normal use conditions, the rear differential fluid check interval is set at 1 month or 250 hours, whichever comes first.
  • The change interval for rear differential fluid on the CP221 and CP271 under normal use is 6 months or 1000 hours, a dual-condition threshold that ties calendar time to operational hours.
  • The CP275 shares the same check and change intervals as the CP221 and CP271 under normal use conditions, with checks at 1 month or 250 hours and changes at 6 months or 1000 hours.
  • The CP275 carries an initial service entry specifying a rear differential fluid change at 50 hours, a break-in interval intended to remove metal particles and contaminants generated during early mechanical wear-in of the drivetrain.
  • The initial service change at 50 hours on the CP275 applies to the same 20-liter rear differential capacity as the normal use entries, meaning a full 20-liter service fill is associated with that early drain interval.
