Usage:
NOTE: Earlier and later valve groups may be identified by checking switch (7). On earlier valve groups, switch (7) has two leads. On later valve groups, switch (7) has four leads.
(1) Torque for 11 bolts ... 32 ± 4 N·m (24 ± 3 lb ft)
(7) Torque for switch (earlier) ... 40.7 N·m maximum (30 lb ft maximum)
Adjustment Procedure For Valve Linkage (Earlier)
NOTE: Adjustments must be made with the valve removed from the tractor.
1. Move piston (4) toward brake engaged position (piston moving out of valve body) until free movement stops. With piston (4) in this position, adjust link (8) until lever (6) closes switch (7) and allows current to flow.
2. Now move piston (4) toward clutch engaged position (piston moving into valve body) until free movement stops. With piston (4) in this position, and plunger (3) in its free position, adjust link (5) until roller (2) is at dimension (A) of 0.08 ± 0.08 mm (.003 ± .003 in) from link (5).
3. Make sure lever (6) is not in contact with switch (7) after piston (4) and plunger (3) are adjusted as described in Step 2.
Adjustment Procedure For Valve Linkage (Later)
NOTE: Adjustments must be made with the valve removed from the tractor.
1. Move piston (4) toward brake engaged position (piston moving out of valve body) until free movement stops. With piston (4) in this position, adjust link (8) until lever (6) closes switch (7) and allows current to flow.
2. Now move piston (4) toward clutch engaged position (piston moving into valve body) until free movement stops. With piston (4) in this position, and plunger (3) in its free position (no external force applied), adjust link (5) until roller (2) is at dimension (A) of 0.08 ± 0.08 mm (.003 ± .003 in) from the front face of link (5).
3. With piston (4) remaining toward the clutch engaged position, and plunger (3) in its free position, readjust link (8) until roller (2) is 1.50 ± 0.13 mm (.059 ± .005 in) from the front face of link (5).
4. Move piston (4) to the full clutch engaged position (piston moved into the valve body until bottomed). This compresses springs and will require that a lever be attached to the external shaft on the valve to gain the necessary leverage.
5. With piston (4) in the full clutch engaged position, there must be a minimum clearance of 0.08 mm (.003 in) between roller (2) and the rear face of link (5).
