The intermediate and high sliding gear and the low and reverse sliding gear are now fitted to exceptionally close limits on the trans- mission main shaft. In addition the parts are selectively assembled. This procedure insures extremely accurate fitting and it eliminates any possibility of the gears coming out of mesh. The new dimensions of these parts are as follows:

((610))

Transmission main shaft A-7061 (See “D,” Fig 610) changed outside diameter from 1.2465/12475 to 1.2485/1.249 Width of splines (See “W,” Fig. 610) changed from .3095/.3115 to .308/.309.

Transmission low and reverse sliding gear A-7100 and transmission high and intermediate sliding gear A-7101, the large diameter of the splined hole in these parts has been changed from 1.2490/1.2505 to 1.2495/1.2505.

Due to the close limits to which these parts are held it will be necessary when installing new shaft and gears to assemble the parts by selective fit.
