Hudson Pacemaker

Differential fluid capacity & service interval

Hudson Pacemaker differential fluid capacity ranges from 1,4 kg to 1,6 kg. Service intervals include checks at 1000 miles and changes at 10000 miles. Data covers 1 configuration.

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

TypeSpecifications
  • Pacemaker (1949-1952)
  • Rear
  • Use: Normal
  • Capacity 1,6 kg
  • Capacity 1,4 kg (Hydra-Matic models)
  • Check 1000 miles
  • Change 10000 miles

Additional Notes

  • The rear differential on the Hudson Pacemaker carries a fluid capacity of 1.6 kg under normal use conditions, which reflects a standard service fill volume for the conventional transmission pairing.
  • Pacemaker models equipped with Hydra-Matic have a reduced rear differential capacity of 1.4 kg, indicating that the Hydra-Matic drivetrain configuration alters the physical space or design of the differential housing enough to affect fluid volume.
  • The normal use condition check interval is set at 1,000 miles, meaning fluid level verification was expected at relatively frequent early intervals by modern standards.
  • The change interval under normal use is specified at 10,000 miles, applying to the 1949-1952 model years across both the standard and Hydra-Matic differential configurations.
