I have a 1941 Chevy 1/2 ton, model AK in which I have been having trouble finding good quality 3:55 rear gears. On the first set, the mounting surface of the ring was unevenly machined and full of chatter marks. On the second set I’m having a hard time setting the backlash. I took readings from seven different spots around the ring and came up with six different readings .010”, .014”, .013”, .015”, .011”. 011”, and .008”. My target is .010”. Ring gear runout is .0015”. The carrier bearings are preloaded.
What are your thoughts? Has anyone had this issue before and what did you do? Does anyone know where to find good quality gears that can be set up? Does anyone know of a set of NOS 3:55 gears for sale?
Any help would be appreciated.
