Terex PPM Mobile truck cranes

Transfer case fluid capacity & service interval

Terex PPM mobile truck cranes utilize transfer case fluid with a capacity range of 1,4 to 11 liters. Service intervals for fluid changes are 500 to 2000 hours. The data covers 2 configurations.

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

TypeSpecifications
AC55
  • Use: Normal
  • Capacity 1,4 liter
  • Change 2000 hours
ATT900
  • Use: Normal
  • Capacity 11 liter
  • Change 500 hours

Additional Notes

  • The AC55 transferbox holds 1.4 liters of fluid, a relatively small capacity consistent with a compact transfer case assembly in a mobile crane configuration.
  • The ATT900 transferbox capacity of 11 liters is substantially larger than the AC55, reflecting a heavier-duty transfer case suited to a higher-tonnage crane platform.
  • Under normal use conditions, the AC55 transferbox fluid change interval is set at 2,000 hours, which is a notably extended service interval compared to many heavy equipment transfer case schedules.
  • The ATT900 transferbox carries a 500-hour fluid change interval under normal use conditions, a significantly more frequent service requirement than the AC55 despite both operating under the same use classification.
  • The gap between the AC55's 2,000-hour interval and the ATT900's 500-hour interval represents a fourfold difference in service frequency between the two Terex PPM mobile truck crane configurations.
