EATON HP-30 MOTOR SERVICE MANUAL E-MOGG-RR001-E June 2015 31Reassembly(Single and Two Speed Standard and Wheel Motor)9.2 Final assembly (For single speed standard andwheel motor)9.2.1 Install main drive with longest spline length (ifasymmetric) into output shaft spline.9.2.2 Place Geroler assembly (seal groove up) over BearingHousing. Install greased O-ring section seal (139,4[5.49] ID) in seal groove of Geroler assembly. Alignshuttle flow hole of Geroler with shuttle flow hole ofBearing Housing.9.2.3 Mark drive teeth that align (See Figure E) with dykempen. Install valve drive into internal star spline (SeeFigure F or G for motor timing).9.2.4 Install valve plate onto Geroler sub-assembly (valveplate valve slots up). Align shuttle flow hole of valveplate with shuttle flow hole of Geroler sub-assembly.9.2.5 Install valve onto valve drive and selector plateassembly. Ensure long leakage groove is aligned withmarked tooth on valve drive (see Figure H).9.2.6 Carefully invert valve housing and place onto valveplate. Make sure that shuttle flow holes are aligned.9.2.7 Install nine cap screws lubricated with DTE-26. Pre-torque each in a crisscross pattern (see Figure 14) to80+/-10 lb-ft. Finally, in a crisscross pattern, tightenscrews to 105+/-5 lb-ft.9.2.8 Install two cap plugs in main ports (Optional).9.2.9 Install key and hex nut into shaft if required.9.3 Bearing housing assembly (For two speedstandard and wheel motor)9.3.1 With Bearing Housing O-ring grooves up (see Figure11), install O-ring section seal (139,4 [5.49] ID)Bearing Housing. Install back-up ring (62,1 [2.45] OD)over O-ring (55,2 [2.18] ID) with flat side up. Back-upring and O-rings may be greased to assist in retainingparts.9.3.2 Install wavo spring in groove in Bearing Housing.9.3.3 Install back-up ring (99,7 [3.93] OD) in groves ofbalance plate sub assembly and then install O-ring(95,0 [3.74] ID) over back-up ring from tapered side.9.3.4 Install balance plate sub assembly in Bearing Housingwith tapered side down.9.3.5 Install plug at 43 degree from horizontal centerlinewhile viewing from shaft end (balance plate port),see Figure 12. Plug may have light coat of oil orpreservative. Torque plug to 46 +/-2 lbf-ft.9.4 Spool housing assembly (For two speedbearingless motor)9.4.1 Install control spool into spool housing by firstlubricating control spool with DTE26. Install controlspool into spool bore, verifying that the control spoolmoves freely in bore.9.4.2 Install nested springs and counter bored plug into endof spool housing spool bore. Plug may have light coatof oil or preservative. Torque plug to 46 +/-2 lbf-ft.9.4.3 Install plug in opposite end of spool bore. Plug mayhave light coat of oil or preservative. Torque plug to46 +/-2 lbf-ft.9.4.4 Install plug into spool housing port and torque to 192+/- 19 lbf-in.43°Figure 121963852749 3 1 5 78 6 2 4 10Figure 14Figure 13
