Additional Notes

  • The front differential fluid capacity across all listed Sonalika tractor models — spanning the DI-50 RX through the WT-90 — is specified as a range of 5 to 6 liters. A range rather than a fixed value reflects normal manufacturing tolerances and the practical variation between a drain-and-refill service fill and a fully dry assembly fill.
  • Under normal use conditions, a fluid level check is scheduled at every 50 hours of operation across all listed models. Frequent interval checks of this kind are standard practice for front differentials on tractors, where off-road terrain and load variation can accelerate fluid loss or contamination.
  • The normal-use fluid change interval is set at 750 hours for every model in the specifications. At that interval, accumulated metal particles, moisture, and oxidation byproducts in the fluid are considered sufficient to warrant a full drain and refill.
  • An initial service change interval of 250 hours applies to all listed models. Early fluid changes at reduced intervals are common in new or rebuilt drivetrain components, as the break-in period generates higher levels of fine metallic wear particles that benefit from early removal.
  • The initial service interval of 250 hours represents one-third of the standard 750-hour change interval. After the initial service change is completed, subsequent changes revert to the normal 750-hour schedule.
  • The ITL 3102 IL engine designation appears in the DI-50 RX and DI-52 RX configurations, both sharing identical front differential capacity and service interval specifications of 5-6 liters, 50-hour checks, 750-hour normal changes, and 250-hour initial changes.
  • The ITL 4100 FL engine is paired with the DI-60 RX and DI-60 models, while the ITL 4100 FLT designation covers the DI-65 RX, DI-75 RX, DI-75, and WT-75. Despite the engine designation difference between FL and FLT variants, the front differential capacity and service intervals remain consistent across all of them.
  • The ITL 4105 FLT engine appears in both the DI-90 and WT-90 models. Both share the same 5-6 liter front differential capacity and the same 50-hour check, 750-hour change, and 250-hour initial service schedule as the lower-displacement configurations.
