HBM-Nobas Graders

Differential fluid capacity & service interval

HBM-Nobas Graders use differential fluid with capacities ranging from 8,5 to 15 liters. Service intervals include checks at 500 hours and changes at 500 hours or 12 months/2000 hours. The data covers 4 configurations.

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

Additional Notes

  • The HBM-Nobas Graders BG 130TA-4 rear limited slip differential carries a fluid capacity of 13.5 liters, which applies equally under both normal use and initial service conditions.
  • Under normal use, the BG 130TA-4 rear limited slip differential follows a check interval of 500 hours, with a change interval set at 12 months or 2000 hours, whichever comes first.
  • The initial service entry for the BG 130TA-4 rear limited slip differential specifies a fluid change at 500 hours, which coincides with the normal-use check interval but precedes the standard 2000-hour change interval by a considerable margin.
  • The BG 160 TA with Perkins 1006-60T engine, covering model years 1997-2003, carries separate front and rear differential fluid capacities, with the front differential holding 8.5 liters and the rear differential holding 15 liters.
  • The rear differential on the BG 160 TA with Perkins 1006-60T holds 15 liters, a figure notably larger than the 13.5-liter rear differential capacity listed for the BG 130TA-4, reflecting differences in drivetrain design between the two configurations.
  • The front differential on the BG 160 TA with Perkins 1006-60T holds 8.5 liters, which is substantially less than the 15-liter rear differential capacity on the same machine, indicating a meaningful difference in the size and design of the front versus rear axle assemblies.
