Additional Notes

  • Across all Ford 20 series models from 1988-1996, front differential fluid checks are scheduled at 50-hour intervals under normal use conditions, while full fluid changes are required at 300 hours.
  • The 1120 and 1220 share an identical front differential fluid capacity of 1.8 liters, placing them among the smallest-capacity units in the 20 series lineup for 1988-1996.
  • The 1320 and 1520 both carry a front differential fluid capacity of 3 liters, representing a mid-range fill volume within the 1988-1996 model group.
  • The 1720 and 1920 share a front differential fluid capacity of 5 liters, reflecting a larger differential housing compared to the lower-numbered models in the same production period.
  • The Ford 20 2120 (1988-1996) holds the largest front differential fluid capacity in the series at 5.8 liters, indicating a heavier-duty front axle assembly relative to all other models in the group.
  • The progression from 1.8 liters in the 1120 and 1220 up to 5.8 liters in the 2120 corresponds to increasing model size across the 1988-1996 range, with each capacity tier shared between two consecutive model designations except for the 2120.
