Dynapac Pneumatic tyred rollers, CP

Automatic transmission fluid capacity & service interval

Dynapac Pneumatic tyred rollers, CP models require automatic transmission fluid with a capacity of 18,5 liters. Service intervals include checking every 10 hours and changing every 6 months or 1000 hours. The data covers 2 configurations.

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

TypeSpecifications

  • Use: Normal
  • Capacity 18,5 liter
  • Check 10 hours
  • Change 6 months/ 1000 hours
CP271, Cummins 4B-4.5C (*2362(BR)0700*->)
  • Use: Normal
  • Capacity 18,5 liter
  • Check 10 hours
  • Change 6 months/ 1000 hours

Additional Notes

  • The torque converter on the Dynapac CP221 with Cummins 4B-4.5C engine holds 18.5 liters of automatic transmission fluid, a volume consistent with a full service fill that includes the converter circuit rather than the transmission sump alone.
  • The CP271 with Cummins 4B-4.5C engine carries an identical 18.5-liter torque converter capacity, placing both configurations on the same fluid volume requirement.
  • A fluid level check interval of 10 hours applies to both the CP221 and CP271 torque converter systems under normal use conditions, reflecting the frequency typical for heavy equipment operating in demanding duty cycles.
  • The fluid change interval for both configurations is set at 6 months or 1,000 hours under normal use conditions, whichever comes first, a dual-trigger structure that accounts for both calendar aging and operational wear of the fluid.
