Bomag Soil stabilizers/asphalt recyclers, MPH

Coolant capacity & service interval

Bomag Soil stabilizers/asphalt recyclers, MPH utilize coolant with a capacity range of 50 to 80 liters. Service intervals include checks at 10 hours and changes at 500 hours or 12 months, and 2000 hours or 24 months. The data covers 3 configurations.

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

TypeSpecifications
MPH-122-2, Deutz TCD2015 V06 (S/N 101 590 06 1014/16) (2006- )
  • Use: Normal

MPH-125, Deutz TCD2015 V08 (S/N 101 590 20 ...->) (2006- )
  • Use: Normal
  • Capacity 80 liter
  • Check 10 hours
  • Change 2000 hours/ 24 months
MPH-121, Deutz BF6M 1015 (S/N 101 590 02 ...->)
  • Use: Normal
  • Capacity 50 liter
  • Check 10 hours
  • Change 500 hours/ 12 months

Additional Notes

  • The MPH-121 with Deutz BF6M 1015 engine carries a 50-liter cooling system capacity, which represents the total system fill volume including the engine block, radiator, and associated lines.
  • The MPH-122-2 with Deutz TCD2015 V06 engine also holds 50 liters of coolant, matching the MPH-121 in capacity despite the difference in engine series.
  • The MPH-125 with Deutz TCD2015 V08 engine holds 80 liters, a notably larger volume that reflects the eight-cylinder configuration compared to the six-cylinder units in the other two models.
  • All three configurations share a 10-hour coolant level check interval under normal use conditions, indicating a frequent visual inspection requirement typical of heavy-duty construction equipment operating in demanding environments.
  • The MPH-121 carries a coolant change interval of 500 hours or 12 months under normal use, whichever comes first, a significantly shorter service life than the TCD2015-equipped models.
  • The MPH-122-2 and MPH-125 both specify a coolant change interval of 2000 hours or 24 months under normal use conditions, representing a four-times longer drain interval compared to the MPH-121.
  • The difference in change intervals between the BF6M 1015 and TCD2015 engine families reflects a generational shift in Deutz engine technology, with the TCD2015 series supporting extended coolant service life.
  • The Bomag MPH-125 cooling system, at 80 liters, is the largest among the three configurations, and a fill of that volume requires careful attention to air bleeding procedures to avoid air pockets that can cause localized overheating.
