TRANSFER GEARCASE. Daily, check level of oil in transfer gearcase. Add oil (OE/HDO or OEA),
as needed, to bring oil level between ADD and FULL marks on gauge rod. Every 150 hours, 1500
miles, or semiannually, drain gearcase oil. Drain only when hot(after operation). To drain, remove
hull drain plug (TM 9-2350-261-20) and gearcase drain plug. Check oil being drained for metallic
particles. If metal chips are found in oil, notify direct support maintenance. Drain at least 15
minutes. Clean and install gearcase drain plug. Fill transfer gearcase with approximately 2-1/2
quarts of oil (OE/HDO or OEA). Make sure gearcase filler cap is closed. Start engine and operate
for 1 minute. Stop engine and check oil level. Level should be between FULL and ADD marks on
gauge rod. Install hull drain plug securely.
