GEARBOX ARRANGEMENTS (Secondary Gearboxes)
All Three secondary Gearboxes have the same identical parts in them for 540 or 1000 RPM and for the left,
center, or right sections. To change Gearbox from 540 to 1000 RPM, the Gear (#1) and Pinion (#2) must be
reversed. Remove the Gear from the Cross Shaft and the Pinion from the vertical Output Shaft. Install the Gear
on the vertical output shaft and the pinion on the Cross Shaft. Reassemble the Gearbox allowing .008 to .012
backlash. Repeat this procedure on all three Gearboxes. When removing the Bearings and Gears, do not mar
the Grease Seal Race. Be extremely careful when installing the Grease Seals so they will not be damaged.
