The constant lack of spare parts and the lack of special tools have never scared our motorists.


Motorists of the early 30s boldly undertook rather complicated work, relying mainly on their own ingenuity and uncomplicated homemade appliances.

Cracked pistons were often welded, machined on a lathe and returned to the engine. Sometimes it was possible to pick up a new piston, suitable in diameter and height, but much harder (sometimes 200 grams!) Native. The mass was adjusted to “face value” by drilling holes in the part (below the axis of the piston pin). After such a refinement, the piston was safely placed in the engine. And went!

To extrude the old finger, a simple device was usually used (see Fig. 1). A U-shaped clamp was bent from a steel strip 2.5–3 mm thick. On one side, a hole with a diameter slightly larger than a finger was drilled in it, and on the other, a plate with a threaded hole was inserted into special slots. A bolt was pushed into it, pushing out an unyielding finger.
