Solis/Sonalika (ITL) Tractors Sonalika

Power steering fluid capacity & service interval

Solis/Sonalika (ITL) Tractors Sonalika power steering fluid capacity is 3,5 liters. Service intervals include checking at 50 hours and changing at 50, 750, or 1000 hours. The data covers 10 configurations.

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

Additional Notes

  • The power steering system capacity across all listed Sonalika/Solis tractor configurations — the 75N (ITL 4100 ELT), DI-60 Super RX MM (ITL 3105 IL), DI-90 (ITL 4105 FLT), WT-75 (ITL 4100 FLT), and WT-90 (ITL 4105 FLT) — is uniformly specified at 3.5 liters, indicating a consistent reservoir size across the range.
  • All listed configurations share an initial service fluid change at 50 hours of operation. An initial service interval at such an early stage is typically intended to flush out any manufacturing residues or break-in contaminants from the steering system.
  • Under normal use conditions, the 75N (ITL 4100 ELT) carries a power steering fluid change interval of 1,000 hours, which is notably longer than the 750-hour change interval specified for the DI-60 Super RX MM, DI-90, WT-75, and WT-90 models under the same conditions.
  • The 750-hour normal-use change interval applies to four configurations: the DI-60 Super RX MM (ITL 3105 IL), DI-90 (ITL 4105 FLT), WT-75 (ITL 4100 FLT), and WT-90 (ITL 4105 FLT), placing them on a more frequent replacement schedule than the 75N.
  • A fluid level check at every 50 hours is specified under normal use for all configurations. Periodic checks at such intervals serve to detect gradual fluid loss or contamination before a full change becomes due.
  • The initial service change at 50 hours coincides with the normal-use check interval across all configurations, meaning the first scheduled inspection and the break-in fluid change fall at the same operational milestone.
