13.Slide input seal (4) onto input shaft (5) and press into housing flush with front using a tube of correct diameter. Be careful not to damage seal lip.
14.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.
15.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.
CROSSBAR REMOVAL
1.It is necessary to gain access to bottom side of cutter for crossbar removal. See Blocking Method, page 16.
NOTE: You will need to use either the puller screw (Item 6, Figure 15) or a small hydraulic jack to remove the crossbar.
2.To make crossbar removal easier, remove blades. See Figure 14.
Figure 14. Blade Removal
3.Refer to Figure 15. Remove retaining wire from bottom of crossbar and remove nut and washer.
4.Attach a clevis (1) to each end of crossbar, using blade pins, washers, and nut.
5.Position tube assembly (5) with threaded nut toward crossbar for puller screw removal or down for hydraulic jack 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 degrees. Use care to prevent bend- ing crossbar during removal.
