Bord 120 - Off to the Races

When work first began on the transmission in Bord 120 the roller bearings in the planetary gearbox were frozen in their raceways.

After chemically cleaning and lubricating the bearings, they were gently tapped until they came free.

The gears were then rotated with a mechanical aid until all the bearing and raceway surfaces were treated. Once the assembly was freed, treatment and cleaning continued until the gears could be rotated smoothly.

Here the entire upper section is receiving a bath. A pump circulates fluid through the unit to thoroughly flush the assembly.
