Atlas Weyhausen (Weycor) Compaction Roller, AW

Coolant capacity & service interval

Atlas Weyhausen (Weycor) Compaction Roller, AW models utilize coolant with a capacity range of 15 to 25 liters. Service intervals include checking every 10 hours and changing every 24 months or 3000 hours. The data covers 5 configurations.

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

Additional Notes

  • The Atlas Weyhausen (Weycor) Compaction Roller AW cooling system capacities split into two distinct values across the Tier 3 lineup: 25 liters for the AW1070, AW1130, and AW1140, and 15 liters for the AW1110 and AW1120. A 10-liter difference between configurations is a meaningful distinction when preparing coolant for a service fill.
  • The AW1110 and AW1120 share an identical 15-liter cooling system capacity under normal use conditions, indicating a closely related engine or cooling circuit architecture between those two models.
  • The AW1070, AW1130, and AW1140 each carry a 25-liter cooling system capacity, which represents the larger of the two capacity groups within the Tier 3 range and points to a more substantial engine cooling demand in those configurations.
  • All five Tier 3 configurations specify a coolant level check interval of every 10 hours under normal use conditions. A 10-hour check interval is among the more frequent inspection schedules seen in heavy compaction equipment, reflecting the thermal demands placed on the cooling system during operation.
  • The coolant change interval across all five Tier 3 models is set at 24 months or 3,000 hours, whichever comes first under normal use conditions. The dual-trigger format means time elapsed can mandate a change even when the hour threshold has not been reached, which is relevant for machines with lower annual utilization.
  • All five models covered the same 2008-2016 production span under Tier 3 emissions classification, meaning the cooling system specifications listed apply uniformly across that entire period for each respective configuration without year-based variation within the range.
