Additional Notes

  • The Hidromek Backhoe loaders cooling system capacity of 18.5 liters applies to both the HMK 102B with the John Deere 4045HF485 Tier 3 engine and the HMK 102S with the Perkins 1104D-44TA Tier 3 engine.
  • A 10-hour check interval is specified for the cooling system across both configurations, reflecting a high-frequency monitoring requirement relative to the change interval.
  • The coolant change interval is set at 2000 hours or 24 months, whichever comes first, under normal use conditions for both the John Deere and Perkins engine variants.
  • The 2000-hour or 24-month change interval means that calendar time can trigger a coolant change before the hour threshold is reached, particularly in lower-utilization applications.
