STEER CONTROL LINKAGE ADJUSTMENT

1. With vehicle steer control in no steer position (centered); adjust steer control linkage so that steer position

indicator on steer control valve is centered. Steer position indicator is centered when it points directly to right side

of transmission.

2. Check left hand right steer position of vehicle steer control against positions of steer indicator. When vehicle steer

control is fully left, steer control indicator must be 30--1/2 degrees (from centered position) toward rear of

transmission. When vehicle steer control is fully right, steer position indicator must be 30--1/2 degrees (from

centered position) toward front of transmission.

3. If steer position indicator or vehicle steer control cannot be positioned properly, inspect linkage for binding, wear

and damage (TM 9--2350--256--20).

STEER OIL PRESSURE ADJUSTMENT

1. Steer oil pressure can be increase by installing spacers (1) between spring (2) and cover (3).

2. Each spacer will increase steer supply pressure approximately 5--1/2 psi. No more than three spacers should be

installed. If pressure cannot be increased to proper level by installing three spacers, check spring for load. If

spring is not within specified load limits, replace with new spring. Refer to WP 0031 00 for disassembly and

assembly procedures.
