Merlo Access platforms, MPR

Differential fluid capacity & service interval

Merlo Access platforms, MPR utilize differential fluid with a capacity of 5,3 liters. The service interval for fluid changes is 1500 hours. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Merlo Access platforms MPR 20, MPR 25, and MPR 30 each carry a front differential fluid capacity of 5.3 liters under normal use conditions.
  • The rear differential on all three MPR variants within the 2008-2012 range shares the same 5.3-liter capacity as the front, meaning both axles require equal fill volumes during a service.
  • A 5.3-liter capacity per differential is a moderately substantial fill volume for a machine in the access platform class, reflecting the load-bearing demands placed on the axle assemblies of aerial work platforms.
  • The fluid change interval for every differential position across the MPR 20, MPR 25, and MPR 30 is set at 1500 hours under normal use conditions, placing all three models on an identical service schedule for differential maintenance.
  • Hour-based service intervals, such as the 1500-hour mark specified here, are standard practice for construction and access equipment, where calendar time is a poor proxy for actual mechanical wear compared to operational hours logged.
  • Because the front and rear differentials on each MPR variant share both the same capacity and the same 1500-hour change interval, a full differential service on any single unit involves draining and refilling a combined total of 10.6 liters of fluid.
  • The uniformity of the 5.3-liter capacity and 1500-hour interval across the MPR 20, MPR 25, and MPR 30 for 2008-2012 suggests a shared axle architecture across all three variants in that production period.
