1. On vehicles equipped with Detroit transmissions, the release bearing does not need to be lubricated. On vehicles equipped with Eaton Fuller UltraShift PLUS transmissions, lubricate the release bearing every 50,000 miles (80 000 km) or 3 months.
2. If equipped with an oil-coalescing desiccant cartridge, replace the cartridge once a year, regardless of mileage. Otherwise use the M3 maintenance interval.
3. Complete this procedure every 25,000 miles (40 225 km), 3 months, or 500 operating hours, whichever comes first.
4. The automatic drain valve should be inspected every 6 months or 1500 operating hours, whichever comes first.
5. M1 maintenance interval should be used as a general guideline; the actual frequency of filter element replacement will vary depending on cleanliness of the fuel station system.
