4.Refer to Figure 13. Attach a 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 (4) 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°. Use care to prevent bending cross- bar during removal.
