Unbolt the radius rod at re ar end, remove the axle pivot pin retaining snap ring and remove thu pivo t pin (P-F lg. CM3). Raise irollt of tractor, allowing axle to drop down far enough to remove the pivot pin bushing from axle main member. New bushing shou ld be final sized a lter Installation to provide a rree fit for the pivot pin . MANUAL STEERING SYSTEM General Purpose and High Clearance Models 7. ADJU STMENT. The stee r ing lear unit is provided with two adjustment. ; one for the upper stee r ing spIodle en d play, the other for the steedn, worm shaft end play .

The accompanying table lists troubles which may be encoun tered In the operaUon of the power steering system. The procedure for co r rffting most of the troubles is evident; for those not readily rcmedil!d, refer to the appropriate subsequent par a- graphs . SYSnM OPERATING PRESSURE All Mod. r, 18. A pressure test of the hydraulic circuit will dl.sclose whether the pump or some other unit In the system I, malfunctio nin g. To make luch a tcst proceed as follow.: Connect a pressure test gage and a shut-oU valve in a manner slmlla r to that shown In Fig. c:n~. Note that shut-orr valve is connccted in the circuit between the gage and t he contro l valve on the worm shaft. Open the sh ut-oU valve and ru n t he en gine at Idle speed until 011 Is warmed.

Note abo that the p ressure read ing for general purpose and high clearance modell equipped with an 1100 Pit relief valve II lower tban mig ht be expect- e4 . This II due to a normal pressure drop in the torque motor. If the pressure 11 hia: ber than speci- fied, the relief valve Is probably nuck in the closed poslUon. U the pressure Is less than specWed, tum the wheell to Itnlgbt abead position; at w hich t ime, the gage readi ng moul d d rop conllderably. Now Ilow ly close the shut-oU valve and retai n In closed position only long enough to obRrve the ,age readin,.

If the lare read ing incr eases to 725-825 p st on aU models with an 800 psi re Uef valve or 102~-1l 25 psi on an modell with an 1100 psi relief valve, w ith valve closed, the pump is O .K . and the trouble II located in the contro l valve, the power cylinder (o r torque motor) or the connections. WhLle a low pre58ure reading with the shut-oU valve c1O!ed indicates the need of pump repair, It docs not nec- I essarlly mean the remainder of the system Is In good condition. After overhauling the pump, recheck the pressure reading to make sure the control valve, cylinder (or torque motor) ___ FLfItN VAL.VE and connections are in satisfactory operating condition.
