Mi-24 Bord 120, Gearing Up

When the gear box on Bord 120 was opened up, we found plenty of cleanup work to be done.

The smaller(!) parts were removed and cleaned and lubricated by hand to restore free and smooth operation.

While the larger parts were first cleaned and treated in place.

After cleanup and lubrication, all of the assemblies were visually inspected and checked for free and smooth operation before reassembly.

Bill and Brad are looking at the operation of the planetary gearbox in the upper transmission section.
