In Step 9, the rear set of gears were positioned for timing. The front drive gear must now be positioned for correct timing. The following procedure is used in order to correctly position drive shaft (18) into body assembly (4).
Coat drive shaft (18) with clean hydraulic oil. Position drive shaft (18) on the top of the spline coupling.
Before engaging the shaft spline into the coupling, rotate the drive shaft (18) until the valley between two gear teeth is lined up with the center of the nearest dowel hole in body assembly (4).
Drive shaft (18) must engage the coupling. The valley cannot be off-center with the dowel hole. If the valley is off-center with the dowel hole, rotate drive shaft (18) to the next valley.
Repeat Step 25.c until the combination of the valley and the spline will allow the valley to remain centered with the nearest dowel hole in body assembly (4).
Coat idler gear (17) lightly with clean hydraulic oil. Install idler gear (17) into body assembly (4).
