2. Inspect lubricant for metal particles. Presence of a small amount of fine particles (resem-
bling powder) indicates normal wear. Presence of larger particles or a large quantity of
fine particles indicates need for gear housing disassembly and component inspection.
3. Note the color of lubricant. White or cream color indicates presence of water in lubricant.
4. Check drain pan for water separation from lubricant. Presence of water in lubricant indi-
cates the need for disassembly and inspection of oil seals, seal surfaces, O-rings, gas-
kets and gear housing components.
