Install the shaft and gear assembly so the internal splines of the shaft are facing away from the gear housing and toward the rear of the engine.
Install a new o-ring on the hydraulic drive adapter. Lubri- cate the o-ring with clean 15W-40 oil. Lubricate the hydraulic drive adapter bore with clean 15W-40 oil. Align the hydraulic drive adapter over the shaft and gear assembly. Start the three mounting capscrews (M10-1.50 x 35) by hand to align the hydraulic drive adapter with the gear housing. Use a rubber mallet to install the adapter. NOTE: Use care not to damage the o-ring during installa- tion. Tighten the mounting capscrews. Torque Value: 47 [35 ft-lb]
