Ahlmann Front loaders, AF

Additional Notes

• The Ahlmann AF front loader transfer box capacity varies significantly depending on the top speed configuration. The 30 km/h version holds considerably more fluid than the 20 km/h version, reflecting a more complex gearset required to support higher road speeds.
• On the AF 100 and AF 80 with Deutz engines (1997-2001), the 30 km/h transfer box holds 3 liters, while the 20 km/h version holds only 0.5 liters. The six-fold difference in capacity between the two speed variants of the same model points to fundamentally different transfer box assemblies rather than a simple ratio change.
• The AF 1050, AF 1200, and all associated Cummins engine variants (2010-2015) share a 4-liter capacity for the 30 km/h transfer box and 1.25 liters for the 20 km/h version. Both figures are higher than the corresponding Deutz-era capacities, indicating a larger transfer box unit across the later model range.
• An initial service fluid change is specified at 500 hours across all listed models and configurations. This early change interval is standard practice for new mechanical assemblies, as metal particles generated during break-in accumulate in the fluid before normal wear rates stabilize.
• Under normal use conditions, the transfer box fluid change interval extends to 1500 hours for all listed models. The gap between the 500-hour initial service and the 1500-hour normal interval represents a three-fold increase in service life once the assembly has passed the break-in phase.
• A fluid level check at 50 hours is specified under normal use conditions for all models except the AF 100 and AF 80 initial service rows, where no check interval appears. The 50-hour check allows early detection of leaks or consumption before the first scheduled change.
• The AF 1050 is listed with two distinct Cummins engine variants, the naturally aspirated B3.3 and the turbocharged B3.3T, yet both share identical transfer box capacities and service intervals. The engine specification difference does not affect transfer box servicing requirements for that model.
• The AF 1200 is paired with both the Cummins B3.3T and the B3.3TAA, the latter denoting a turbocharged and aftercooled configuration. Despite the added induction hardware, transfer box capacities and service intervals remain the same as the standard turbocharged variant.
