Additional Notes
- For JCB Fastrac 4000 Series 4160-1, 4190-1, and 4220-1 with Agco 66 AWF Tier 4f in 2014-2020, front differential capacity is 10 liter in both normal and initial service entries. Matching capacity across both use conditions indicates a refill quantity rather than a separate overhaul figure.
- Rear differential capacity for 4160-1, 4190-1, and 4220-1 with Agco 66 AWF Tier 4f in 2014-2020 is 11 liter for normal service and 11 liter for initial service. Front and rear values differ by 1 liter on the same configuration.
- For Fastrac 4160-2, 4190-2, and 4220-2 with Agco 66 AWF Stage V in 2020-2022, front differential capacity is 11 liter in normal service, with check intervals at 6 months or 500 hours and change intervals at 12 months or 1000 hours.
- On Stage V 4160-2, 4190-2, and 4220-2 rows, rear differential capacity is 17,5 liter for both normal and initial service. The same rows pair normal service with checks at 6 months or 500 hours and fluid changes at 12 months or 1000 hours, while initial service lists a first change at 100 hours.
- Initial service entries are shorter interval entries than normal service entries across all listed configurations. Front and rear differentials both show a change at 100 hours for initial service, while normal service shows checks at 6 months or 500 hours and changes at 12 months or 1000 hours.
- Tier 4f entries in 2014-2020 use 10 liter at the front differential and 11 liter at the rear differential across 4160-1, 4190-1, and 4220-1. Stage V entries in 2020-2022 use 11 liter at the front differential and 17,5 liter at the rear differential across 4160-2, 4190-2, and 4220-2.
- The specification format uses paired calendar and operating time intervals in normal service rows. In practical terms, a listed value such as 6 months or 500 hours means the maintenance schedule is tied to either elapsed time or machine operating hours for the same differential entry.
