The pre-sized bushing (18) which is pressed into the center member can be removed after the center member has been removed from tractor. The 240, 404 and 2404 International tractors have a "V" shaped, tubular, adjustable front axle which pivots on pin (17-Fig. IH553B). The pivot pin is retained in lower bolster (20) by a cap screw. The pre-sized bushing (18) is pressed into the center member and can be removed after the center member has been removed from tractor. The 404 and 2404 International tractors also have available a heavy duty fixed tread "V" type front axle. This axle is similar to that shown in Fig. IH553B except that tread width is non - adjustable and the steering knuckles and steering arms are splined instead of having Woodruff keys. TIE·RODS AND TOE·IN All Models 4. The procedure for renewing the tie-rods and/or tie-rod ends is evident after an examination of the unit and reference to Figs. IH553, IH553A and IH553B. Tie-rod ends are of the non- adjustable type and excessive wear is corrected by renewing the units. When reassembling, vary the length of each tie-rod, an equal amount, to provide the recommended toe-in of 1fs-%-inch for all series except the 240, 404 and 2404 International which should be /a--%-inch. STEERING KNUCKLES All Models 5. The steering spindle and knuckle units are removed from the axle or axle extensions in the conventional manner. Spindle bushings should be installed with a closely fitting man- drel and sized after installation, if necessary, to provide a recommended clearance of 0.002-0.004 tor the spindle. 5

The small metering hole in the end ot the flow valve piston passes between 2Y.: to 3 gallons per minute to the power steering system; but, since the pump s upplies consid- erably morc than three gpm, pressure builds up in tr on t of the piston and moves the piston, a ga inst spring pressure, until the ports whi ch s upply all to t he Hydra-Touch system are uncov- ered.

The auxlllary safety valve for the power s teering system maintains a system ope r ating pressure of 1200-1500 psi. The components of the flow control valve are shown exploded from the valve housing In Fi i. IH556E. A pressure test of the power steer- Ing circuit will disclose whether the pump, safety valve or some other unit in the system Is malfunctioning . To make s uch a test, proceed as Collows: Connect a pressure test gage and s hut- aU valve In series with the line connecting the flow control valve to the steering valves as shown in Fig. IH- 556F. Notice that the press ure gage is connected in the circuit between the shut-of! valve and the flow control valve. Open the shut-oU vaive and run engine at low Idle speed until oil is warmed. Advance the elliine speed to the specified high idle rpm, close the shut-off valve, observe the pressure gage reading, then open the shut- oU va lve. i.f the gage reading is between 1200 and 1500 psi with the shut- off valve closed, the hydraulic pump and auxiliary safety valve are O.K. and any tr ouble is located elsewhe re in the system. IC the gage reading is more than 1500 psi, the auxiliary saCety valve may be stuck In the closed position. It the gage reading Is less than 1200 psi, r enew the auxiliary safety valve spring and recheck the pre ssur e read- Ing. If the gage reading is still less than 1200 psi, a faulty hydraulic pump is Indicated. For information on the r eiUlator , safety and flow control valve U5em- bly, refer to paragraph 131. $&rles 404·2404 14. Working fluid fo r the hydrauli c power steerini" system Is supplied by the same pump which powers the hydraulic system.

Thus the power stec r lng system receives priority and Its re- qulrements satisfied before any oU flows to the hydraulic s ystem . Hy- drauli c pumpll of 9 gpm capacity are used on tractors with power steering while those tracto rs with no power s teering are equipped wIth 4 YI gpm pumps. A pressure test of the power stee r- ing circuit can be made a! follows ; Connect a pressure gage In seri es with the line connectJni flow control valve to power unit ( Farmall ) or rotary valve (International ) and be sure gage Is between flow control valve and shut-off valve. Open the shut-off valve and run engine at lo w idle speed until all is warmed to operating temperature. Advance engine speed to high idle rpm, close shut - oU valve and observe gage reading which should be 13M-15M psi. Note: To preclude any poulbUity of overheatlni 011 or damaging hydraulic pump, keep ahut-off valve closed on ly long enough to obtain gage readine. F19.
