Re: 1924 Sport 136

The rear axle and the differential gear had to be completely overhauled. All components on the rear axle, such as the brake lever, were dismantled, sandblasted and painted. All bearing bushes were newly manufactured and replaced.
A particular surprise revealed the difference. After removing the housing cover, it looks like someone put “Skippy” in the gearbox. However, it is also possible that the transmission oil has not been changed since 1924.
After thoroughly cleaning and rinsing the gear parts, the component tests revealed, to my great surprise, that there was no wear on the ball bearings and no unacceptable play between the Pinion and Drivin Gear. The ball bearings to the propeller shaft make no noise, which is why I decided not to loosen the spacer tube between the bearings and to remove the ball bearings. To seal the drive shafts, I made and installed new felt sealing rings. The Tork arm bearing/bushing was in good condition and does not need to be replaced.
