System reli ef press ure and fl ow should be as fo llows: Early Pump Pressure, psi ........... 650 Flow, gpm @ 1000 r pm . 3.5 La te Pu mp 6.0 2.74 To check system r elief pressure, in· stall a "1'" fitting in pressure li ne (19- Fi g. 5) at pu mp co nnection and connect a 0-1000 psi gage to fitting. With t he engine runn i ng at 1000 RPM and the fr ont wheels tu rned against lock, gage read ing should be 600-700 psi. 7

CA UTION: When checking system relief pressure, hol d the steeri ng wheel again st lock for only long enough to observe gage reading; pump may be damaged if stee rin g wheel is held in this position for an excessive length of time. To adjust th e pressure on early models, remove pressure relief valve cap (7 - Fig. 7) and add or remove shims (6) as required. If a dding shims under the press ure relief valve cap will not in- crease system pressure, remove and overhaul power steeri ng pump as ou t.- lined in paragraph 12. On late models, pump must be disas- se mbled to adjust opening pressure . Refer to parsgraph 12 and Fig. 10. Shims (25) control system pressure and are avai lab le in thicknesses of 0.010, 0.015 and 0.060. A change of 0.005 in total shim pack thickness will alter sys tem pr ess ur e about 35 psi. La te pump does n ot contain a flow control valve. 8 12 . R&R AND OVERHAUL PUMP. Thoroughly cl ea n pump, lines and s urrounding area. Disconnect lines from pump and allow fluid to drain . Cap all openings to preve nt dirt from entering pump or lines, then un bolt and remove pump assembly from en· gine front plate . When rein s tallin g pump, use new sealing "0 " ring and tighten retaining bol ts to a torque of 23-29 Ft.· Lbs. Reconnect lines, fill and bleed system as in paragraph 10. On early models, ref er to exploded view of pump in Fig. 7 and disaasemble pump as follows: Sc ri be an assembly mark across pump co vers and body. Stra i ghten tab on was her (34 ) and remove nut (35). Pull drive gear (33) from pump shaft and remove key (36). Remov e the four through-bolts and se par ate rear cover assembly (15 ), plate (18), body (2 4) and front cover (29). Remove bearin g blocks (21 and 26) and gears (22 and 23) from pump lUI a uni t.
