Manitou Wheeled loaders, AL

Additional Notes

• Across the AL80, AL100, AL100turbo, and AL120, the front limited slip differential holds either 3.8 liters in the 30 km/h version or 4.2 liters in the 20 km/h version. The lower-speed variant carries a larger front differential fluid volume, a difference of 0.4 liters between the two speed configurations.
• The rear limited slip differential capacities follow the opposite pattern relative to the front. The 30 km/h version holds 5.5 liters while the 20 km/h version holds 5.1 liters, meaning the higher-speed variant carries more fluid at the rear axle.
• Rear differential capacities are notably larger than front differential capacities across all models and speed variants. The rear unit holds between 5.1 and 5.5 liters compared to 3.8 to 4.2 liters at the front, reflecting the greater torque loads typically managed by the rear axle in wheeled loader applications.
• An initial service fluid change is specified at 500 hours for both front and rear limited slip differentials across all listed models. In heavy equipment, an early change interval like this is standard practice to flush metal particles generated during the break-in period of new gear surfaces.
• Under normal use conditions, the fluid change interval extends to 1,500 hours for both front and rear differentials on all models. A level check is also specified at 50 hours under normal use, which serves as an early verification of fluid integrity and fill level without requiring a full drain.
• The initial service entries carry only a change interval at 500 hours, with no separate 50-hour check listed. The 50-hour check interval appears exclusively under the normal use condition rows.
• The AL100turbo shares identical front and rear differential fluid capacities and service intervals with the naturally aspirated AL100. Both speed variants produce the same 3.8/4.2-liter front and 5.5/5.1-liter rear figures, and both follow the same 500-hour initial and 1,500-hour normal change schedules.
