The Cobby Car

The car needed outside bearings to accommodate the shortened axles for 24" gauge running.

Dean machined up a new axle for the front, the other is the original rear axle.

Because of the pitting on the big end journal, the crank was ground out, and the big end bearing remetalled and machined to match.

Note the pitting and rust stains.

The gearbox had also sat filled with water, so all bearings were replaced. A cheat's way to pull out cups is to run a bead of weld around the inside. As the metal cools, it reduces the diametre of the cup and out it falls.


The gudgen or wrist pin. Water had entered the motor this far up. Dan Brown provided a new bearing and wrist pin for us. We also imported new rings and brake blocks.

The motor was in a very poor state, with much welding around it. It had also sat filled with water, as evidenced by the wrist pin above, for some time. When the motor was first started, Dean said that it sounded aweful. Even turning it over by hand was bad enough.

All new bearings were installed, so the old girl should run quite nicely now.
