Additional Notes

  • The Bristol 407 rear differential holds 1.7 liters of fluid, which is a typical service fill volume for a rear axle of this era and reflects the amount needed to maintain proper lubrication under normal operating conditions rather than a full overhaul quantity.
  • The change interval for the Bristol 407 rear differential fluid is set at 20,000 miles under normal use conditions, placing routine drain-and-refill service at relatively wide spacing compared to more frequent drivetrain maintenance schedules common in performance-oriented vehicles of the period.
  • A separate check interval of 2,000 miles is specified alongside the 20,000-mile change interval, meaning the fluid level is intended to be inspected at a much shorter mileage increment than the full replacement cycle, reflecting standard practice for monitoring rear axle fluid integrity between changes.
