I’m rebuilding a Ferguson (F40) engine, and ran into a couple snares as I was getting ready to install the new pistons into the new sleeves.
Anyone know if the pistons that come in a comprehensive overhaul kit for a Continental Z134 are made in such a way that they are not directional like the originals?
Also, the recommended clearance of 0.0025” with ½ feeler gauge seems pretty loose.
I get some resistance more in the 0.003 – 0.004” range.
As a machinist, I’m accustomed to close fits, but from experience understand that printed recommendations can be better understood from someone with practical experience.
Any help would be greatly appreciated.
