Additional Notes
- The Yanmar SA221 and SA424 front differentials each hold 3 liters of fluid, a figure that represents a service fill capacity for normal operating conditions.
- Both configurations share an identical check interval of 50 hours, meaning fluid level inspection is due well before any change is required.
- The change interval for both front differentials is set at 500 hours under normal use conditions, placing the drain-and-refill service at ten times the frequency of the check interval.
