Additional Notes
- The Bell Equipment 1766F with Mercedes-Benz OM366A engine has a transfer box capacity of 2 liters, which is half the 4-liter capacity found across the Deutz and John Deere-powered models in the same rigid tractor and hauler range.
- The 904AF, 1216AF, and 1716AF models, all powered by Deutz engines, share an identical transfer box capacity of 4 liters and a normal-use change interval of 2000 hours, with fluid level checks scheduled at every 250 hours.
- The 1226AF MkIII with John Deere 6068TF150 engine also holds 4 liters in the transfer box, but the normal-use change interval is 1000 hours rather than the 2000-hour interval specified for the Deutz-powered models.
- An initial service change at 100 hours is specified for the 1216AF, 1716AF, 904AF, and 1766F transfer boxes. A 100-hour initial drain is standard practice for new or rebuilt units, as it removes metal particles and manufacturing residues that accumulate during break-in.
- The 1766F transfer box pairs a 100-hour initial service change with a 1000-hour normal change interval, and no 250-hour check interval appears in the specifications for that model, unlike the Deutz-powered units.
- The 250-hour fluid level check interval on the 904AF, 1216AF, and 1716AF transfer boxes runs independently of the 2000-hour change cycle, meaning eight level checks occur between each full fluid change under normal use conditions.
- No initial service entry is listed for the 1226AF MkIII transfer box, whereas the 904AF, 1216AF, 1716AF, and 1766F all carry an explicit 100-hour initial change specification alongside their normal-use intervals.
