Holder S-series

Manual transmission fluid capacity & service interval

Holder S-series manual transmission fluid capacity ranges from 10,9 to 17,75 liters. Service intervals include checks at 250 hours and changes at 50 or 1500 hours. The data covers 4 configurations.

Additional Notes

  • The Holder S-series S990 front transmission carries an initial fill capacity of 12.7 liters, which reflects the full volume required when the unit is dry, such as after an overhaul or component replacement.
  • The front transmission service fill capacity of 10.9 liters is lower than the initial fill, indicating that residual fluid remains in the system during a routine drain-and-refill service, so the full 12.7 liters is not recovered at each change interval.
  • Under normal use conditions, the front transmission fluid level is subject to a check interval of 250 hours, with a full fluid change required at 1,500 hours.
  • Under initial service conditions, the front transmission fluid change interval is set at 50 hours, considerably shorter than the 1,500-hour normal change interval, reflecting the need to remove metal particles and contaminants generated during the break-in period.
  • The rear transmission of the S990 holds 17.75 liters, a single capacity figure that applies to both initial and service fill situations, unlike the front transmission, which distinguishes between the two volumes.
  • The rear transmission shares the same normal-use check and change intervals as the front unit, with a fluid level check at 250 hours and a full change at 1,500 hours.
  • The rear transmission also follows the same 50-hour initial service change interval, aligning the break-in maintenance schedule across both transmission positions on the S990.
