POWER STEERING SYSTEM
RandR AND OVERHAUL
To remove the power steering cylinder, first drain the hydraulic system and remove the battery, generator regulator and the hydraulic manifold connecting pump to reservoir.
Unbolt and remove the rack adjusting pad and shims from bottom of gear housing and save the shims for reinstallation. Refer to Fig. IH608. Disconnect oil lines from cylinder and rack assembly from gear housing.
Using a plastic or lead hammer, bump the cylinder off the cylinder end plate and piston. Remove the nut retaining piston to piston rod, remove piston and withdraw the piston rod from the cylinder end plate.
The procedure for further disassembly is evident. Thoroughly clean all parts in a suitable solvent and renew any damaged or worn parts.
Be sure to examine rubbing surfaces of the gear rack and adjusting pad for excessive wear. Be sure to renew all rings, seals and gaskets.
LUBRICATION AND BLEEDING
Durable, coated paper stands up to messy shop jobs
The regular Hydra-Touch system fluid reservoir is the source of fluid supply to the power steering system.
Only IH "Touch Control" or "Hydra-Touch and Touch Control" fluid should be used in the hydraulic system and the reservoir fluid level should be maintained at the "Full" mark on dip stick.
Whenever the power steering oil lines have been disconnected, reconnect the oil lines, fill the reservoir and cycle the power steering system several times to bleed air from the system; then, refill the reservoir to "Full" mark on dip stick.
