How often are the wheel bearings lubricated on the MRES?

• A. Every 180 Days
• B. Every 365 Days
• C. Every 90 Days
• D. Every 730 Days

Answer: (B)

Regular preventive maintenance for rotating equipment uses a defined lubricant life, balancing protection with service practicality. For the MRES wheel bearings, the lubricant is renewed on a yearly schedule because grease can degrade from temperature changes and contamination over time, and a 12-month interval provides a safe window to refresh the lubricant, inspect seals, and catch wear early. Lubricating more often isn’t needed under normal conditions and can introduce contamination or over-greasing; waiting longer than a year increases the chance of lubricant breakdown and bearing damage. So the appropriate interval is once per year (every 365 days).
