Gallmac Wheeled excavators, WMW

Coolant capacity & service interval

Gallmac wheeled excavators, WMW, require coolant with a capacity range of 19 to 23 liters. Service intervals include checking every 10 hours and changing every 2000 hours or 24 months. The data covers 5 configurations.

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

Additional Notes

  • The Gallmac WMW 100L, WMW 100LT, and WMW 115 all share an identical cooling system capacity of 19 liters, each fitted with the Perkins 1104D-44T engine across the 2008-2010 model years.
  • The WMW 150 carries a notably larger cooling system capacity of 23 liters, regardless of whether the Deutz BF4M2012C or John Deere 4045 HF285 engine is installed.
  • A 24-month change interval applies to all five configurations, establishing calendar time as the consistent service boundary across the entire WMW range for 2008-2010.
  • The Perkins 1104D-44T variants in the WMW 100L, WMW 100LT, and WMW 115 carry no hour-based check interval in the specifications, unlike the WMW 150 configurations.
  • Both WMW 150 engine variants specify a 10-hour coolant level check interval, which reflects a very early and frequent inspection requirement typical of break-in or high-load operating conditions in heavy equipment.
  • The WMW 150 also carries a 2000-hour change interval alongside the 24-month calendar limit, meaning whichever threshold is reached first would govern the service event under normal use conditions.
  • The identical 23-liter capacity and identical service intervals across the Deutz BF4M2012C and John Deere 4045 HF285 variants of the WMW 150 indicate that the cooling system architecture was standardized between the two engine options for that model.
