Bomag Soil stabilizers/asphalt recyclers, MPH

Differential fluid capacity & service interval

Bomag Soil stabilizers/asphalt recyclers, MPH differential fluid capacity ranges from 13,4 to 17,9 liters. Service intervals include checks at 250 hours and changes at 250, 500, or 1000 hours, or 12 months. The data covers 4 configurations.

Additional Notes

  • The Bomag MPH-121 with Deutz BF6M 1015 engine carries a rear differential fluid capacity of 13.4 liters, identical to the MPH-122-2 with Deutz TCD2015 V06 engine, despite the two machines using different engine families.
  • The MPH-125 with Deutz TCD2015 V08 engine holds a notably larger rear differential capacity of 17.9 liters, which reflects the greater fluid volume required by a physically larger differential assembly compared to the 13.4-liter figure seen in the smaller configurations.
  • The MPH-125 rear differential carries an initial service change interval of 250 hours at the same 17.9-liter capacity. An initial service interval is a break-in drain performed earlier than the standard cycle to remove metal particles and contaminants generated during the component's early wear-in period.
  • Following the initial service, the MPH-125 rear differential transitions to a standard change interval of 1000 hours or 12 months, whichever comes first, representing a fourfold increase over the break-in interval.
  • The MPH-121 rear differential specifies a change interval of 500 hours or 12 months under normal use conditions, while the MPH-122-2 and MPH-125 both specify 1000 hours or 12 months, indicating a longer drain cycle for the TCD2015-powered machines.
  • All three configurations share a fluid level check interval of 250 hours under normal use conditions, regardless of differences in capacity or change intervals.
  • The 12-month time limit paired with the hour-based change intervals across all configurations means a calendar threshold applies independently of machine operating hours, which is standard practice for fluid service schedules where seasonal or storage conditions can degrade fluid quality without accumulated runtime.
