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 screw (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 with- out mechanical assistance.
1.Set gearbox on cutter and fasten with bolts and nuts. Torque bolts to 300
2.Attach crossbar (see Crossbar Installation, page 32).
CROSSBAR REMOVAL
1.It is necessary to gain access to bottom side of cutter for crossbar removal. See BLOCKING METHOD, page 20.
NOTE: You will need to use either the puller screw (Item 6, Figure 19) or a small hydraulic jack to remove the crossbar.
2.Remove blade pin hardware, blade pins and blades from crossbar.
3.Remove retaining wire from bottom of crossbar and remove nut and washer.
4.Refer to Figure 19. Attach clevis (1) to each end of crossbar, using blade pins, spacers, keyhole plates, and blade pin clips.
5.Position tube assembly (5) with threaded nut toward crossbar for puller screw removal or down for hydraulic jack removal.
Figure 19. Crossbar Removal
6.For removal with puller screw, attach tube (5) to each clevis with bolts (2) and nuts (3). Place pad
(4)in nut and thread puller screw (6) into nut from bottom. Tighten until pad is solid against gearbox shaft. For best results, strike head of puller screw with a hammer while tightening with a wrench.
7.For removal with a jack, attach tube to each clevis with puller links (7), bolts (2), and nuts (3). Place jack on tube with end of jack pressing against gearbox shaft. Slowly apply force with jack.
NOTE: Hydraulic jack will not operate if tipped more than 90°. Use care to prevent bending cross- bar during removal.
