12.While holding gear (1) in place, slide input shaft (3) through gear (1) and bearing (7). Align splines on shaft (3) and gear (1). Slide spacer (12) over input shaft (3) and press bearing (7) onto input shaft (3), using a round tube of the correct diameter and a hand press.
13.Slide shim (13) over input shaft (3) and secure with snap ring (10).
14.Check input shaft end float by moving the input shaft (3) by hand. If end float is higher than 0.012", insert shim between input shaft (3) and rear bearing (7). Repeat until end float is less than 0.012". Check rotational torque by hand. The torque should be less than 2.2
15.Check that the gear backlash is between 0.006" and 0.016". You should not have to adjust the backlash.
16.Press in input oil seal (19), using tube of correct diameter. Be careful not to damage seal lip.
17.Press oil cap (20) on to cover the rear of housing, using a tube of the correct diameter.
18.Place top cover (22) on top of housing and secure with six cap screws (23).
19.Check gearbox housing for leaks by plugging all holes except one. Apply 4 psi compressed air and immerse the gearbox in water to verify that there are no leaks.
20.Remove gearbox from water and dry off with compressed air. Add SAE 80W or 90W EP oil until it runs out of side level hole. Tighten all plugs.
Reinstall Gearbox
NOTE: Gearbox is heavy: do not attempt to move without mechanical assistance.
1.Set gearbox on cutter and fasten with bolts and nuts. Torque bolts to 300
2.Attach crossbar (Crossbar Installation, page 35).
