I ran across this in the 41-47 shop manual, it may help someone working on there steering box. It also will help if mixing parts around to make one good one like I did. Joe
" NOTE—Due to a design change after the beginning of 1942 production, the early 1942 trucks, conventional and Cab-Over-Engine, contained the same design steering gear as used throughout the 1941 production year on all trucks. The 1941. 66 (1/4") ball type, steering gear in a 1942 truck may be identified as follows:
ON CONVENTIONAL MODEL TRUCKS-by the size of the bolts used to attach the side cover to the housing —5/16" diameter. The 1942, 60 (9/32") ball type, truck steering gear has 3/8" bolts at this point. ON CAB-OVER-ENGINE MODEL TRUCKS-by the casting number cast in the housing on the pitman arm side—No. 266856. The number cast in the housing at this same place on 1942, 106 (9/32") ball type, truck steering gears is No. 267135.
Complete steering gear assemblies are interchangeable between respective model 1941 and 1942 trucks. All overhaul and adjustment instructions in the 1941 Shop Manual covering the 1941 66 (1/4") ball type truck steering gear apply to this first or early design 1942 truck "
