To remove the axle main (ce nter) member (II-Fig. MFI), support trac _ tor under engine, remove the grille l ower panel, disconnect tie rods from the spindle steering arms and remove both axle extensions and wheel as- semblies from the center member. Unbolt and remove the axle pivot thr ust plate (16) and save shims ( 15 ) for relnstaUation. Remove the cap screws retaining pivot bracket (13) to the front support casting and remove the pivot bracket. Pull center member (11) forward and out of rear pivot bushing (12) which Is located in the front support casting. The non-adj ustable axle assemb ly used on Utility models Is renewed In the same manne r except spindles must be wit hdr awn from the one- piece axle member. • Inside diameter ot new pivot bushings is 1.877-1.879 for rear bushing (12) and 2.002-2.004 for fr ont bushing (14). Pivot pin diameter for a new center member is 1.874-1.876 for the rear pin and 1.999-2.001 for the front pin. Renew center member and /o r bushings if running clearance is ex- cessive. Replacement bushings are pre-sized and will not require ream- ing It carefully Installed with a suit- able arbor. Make certain, h owever, that lubrication holes In bushings are in register with similar holes in pivot bracket and front support. NOTE: On some early models, the rear pivot bushing Is not staked In pl ace In front support. When renew- Ing the rear bushing, refer to Fig. MF2 and proceed as follows: Remove the old bwhlng and grease fitUng. Use a l ong 7/32-inch drW bit and, working up thr oug h the grease flt- MASSEY-FERGUSON ting hole, drill a small depression In top wall of bushing bore. Install the new bushing with grease hole in bushing and support aligned, then stake bushing in place by jngertlng a slim punch through grease fitting hole and indenting bushing Into pre- viously drilled depression. When Installing the axle center member, reverse the removal procedure and vary the number of shims (15) to obtain a center member end play of 0.002-0.008 when checked between rear face of pivot bracket ( 13) Dnd Iront face of center member (11 ). Shims are available in thicknesses of 0.00 2, 0.005 and 0.010. SPINDLE BUSHINGS 2. Each a xle extension contains two renewable bushings ( 9) which require final sizing alter installation. Recom- mended clearance between spind les and bushings is 0.0035-0.005. Nominal sp indle diameter is 1 %-inches for adjustable axle models; and 11k-Inches for Utility models. TOE. IN, TIE-RODS AND/ OR DRAG LINKS 3. Tie-rod ends are of the automo- tive type and are not adjustable to compensate for wear. Recommended toe-In 01 0- if. inch Is adjusted by varying the len gth of the right hand tie-rod. This is accomplished by loosening the tube set screw and clamp bolt and turning the tube (2- Flg. MFl) either way as required. Be sure the tube set screw is In the f orward position before tight- ening. Fig. MF2 - 1. .1. pi, ot pin rear bUlhl_ , Inlt o ll ot ion .

Only automatic transmission fluid, Type A Is r eco mmended for use In the power s teer ing IYst em. R eservoi r fluid l eve l and the paper filt er el ement in reservoir should be checked every 750 hours of operaUon or more oft en In severe dust con diti ons. Reservoir fluid l evel Ihou.ld be main t ained 1/ 4- ~_ inch above the filter element. To bl e ed the IYstem, fill relervolr, start engine and tum th e steering wheel t ull r ig ht and full le ft several times to bl eed air fr om the sys tem ; 8 then, refill r ese rv oir to the proper level. TROUBLE SHOOTING 14. The accompanying table li sts troubles which may be encountered In the operatio n ot the power steering system. The procedUre for correcting most of the troubles Is evide nt ; lor those not readily r emedied, refer to the appropriate subsequen t paragraphs. SYSTEM OPERATING PRESSURE AND RELIEF VALVE 15. A pressure t est ot the hydraulic circuit wlll disclose w h e the r the pump, relief valve or some othe r unit in the system I, malfunctionin g. To ma ke such a test, proceed as follows: Connect a p ressur e test gage and s hut- oU val ve in series with the pump preuure line at shown in Fi g. MFI0. Note that the preuure gage Is con- nected in the circ uit b et w een th e MASSEY-FERGUSON """. FkJ . ""FlO - Preu.,.. '0ge alld ,h llt-aH veri".

Advance the en gine speed to 2,000 rpm , close the sh ut -off valve and re- tAin In the closed position on ly long enough to observe th e gage reading. Pump may be se riously damaged if valve Is left in the closed pos iti on lor more than 10 seconds. If gage reading Is 1,100 psi with the s hut-off valve closed, the pump and re lie! valve are O. K. and any trouble Is located In the contr ol valve, power cylinder and / or connectio ns. If the pump output pressure Is more than 1,100 psi, the rell el valve is either improperly adjusted or s tuck in the closed pos ition . U th e output pressure is less than 1,100 psi, e ither the rellel val ve Is improperl y adjusted or the pump req u ires ove rhau l1ng. In any even t, the first ste p In eliminating trouble Is to adjust the relief valve . This may be accomplished by removin g the r eservoir cover and rilter e le- men t on non - diesel models; or cap plug on t op of pump ( dlesel.s), and turning the r elle! valve adjusting screw ( 20-Fig. lIU'U) eit her way as required .
