In Part 2 we will have a look on the heart of the engine : the Crankshaft
This is a forged crankshaft from the USA
The first thing is always quality inspection!
This crankshaft was ok from the measurements and it didn`t runout when I check it between 2 centers on the lathe.
For this engine I decided to make an additional heat treatment:
Teniferieren in german or ferritic nitrocarburizing in english
Check the links:
After this was balancing: Uaah 30 gramms out of balancing!! at the first check.
But now it's perfect, alone and together with the flywheel and the Kennedy pressure plate.
For sure JPS 3,3kg Cromo Flywheel
Have a great Weekend!
