Case # 339
4:1
New main shaft and range shift collar
Had new high speed gear that was not back-cut, but cast that way.
Could not install the stepped thrust washers provided in the kit as even when using the thinnest step, the clearence was too tight.
Orion kit came with a new shift rail that had o-ring grooves on both ends, and was machined for the use of the set screw locking system, but the case was not machined for it.
Installed behind an H41
Assembly of this is detailed out here.
