Caterpillar Pneumatic compactors, PF/PS/CW

Coolant capacity & service interval

Caterpillar Pneumatic compactors, PF/PS/CW use coolant with a capacity range of 18,8 to 40 liters. Service intervals include checks at 10, 250, and 500 hours or 12 months, and changes at 24, 36, or 72 months or 3000, 6000, or 12000 hours. The data covers 11 configurations.

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

Additional Notes

  • The Caterpillar CW14 (LTJ, 2012- ) cooling system holds 32 liters, while the CW34 (C34/CT3/J3H/TLJ, 2012- ) holds 27.4 liters, reflecting the difference in engine and system size between the two compactor models.
  • The PS-500 (7XD, 1986-2002) carries the largest cooling system capacity in the lineup at 40 liters, paired with a change interval of 24 months or 3,000 hours under normal use conditions.
  • The PF-300C (PFB, 2004-2008) and PS-300C (PFS, 2004-2008) each list two capacity values: 30 liters as the base figure and 32.5 liters when a cabin is included, indicating that the optional cab adds measurable volume to the cooling circuit.
  • Under the fluid analysis preferred condition, the CW14 and CW34 (both 2012- ) share a change interval of 72 months or 12,000 hours, which is significantly longer than the 36-month or 6,000-hour interval specified for the PF-300C and PS-300C under normal use.
  • The PS-500 (7XD, 1986-2002) carries a shorter change interval of 24 months or 3,000 hours under normal use, which is half the time and half the hours of the 2004-2008 models operating under the same condition type.
  • The fluid analysis alternative condition for the CW14 specifies only a 250-hour check interval with no change interval listed, whereas the preferred condition for the same model adds a 12-month check and a 72-month or 12,000-hour change interval.
  • The CW34 (2012- ) includes a fluid analysis initial (preferred) entry with a 500-hour check interval, a condition type also present for the PS-150C (FPS/NPK, 2010- ), distinguishing an early-service monitoring point from the ongoing preferred and alternative schedules.
  • The PS-150C (FPS/NPK, 2010- ) holds 18.8 liters, the smallest cooling system capacity across all configurations listed, and shares the 72-month or 12,000-hour change interval under the fluid analysis preferred condition with the 2012- CW-series models.
  • The PF-300C and PS-300C (both 2004-2008) specify a 10-hour check interval under normal use, a notably short interval compared to the 250-hour, 500-hour, or 12-month check intervals assigned to the 2010- and 2012- models under fluid analysis conditions.
