Illustration 1 g02083474
Typical former steering control unit (A) 12 point bolts (B) Machine end cap (C) Gerotor outer ring (D) Gerotor star (E) Spacer (F) Metering body (G) Square section ring
Remove 12 point bolts (A)
Remove machine end caps (B)
Remove gerotor outer ring (C) and square section ring (G)
Remove spacer (E)
Remove square section ring (G) from metering body (F)
Illustration 2 g02083613
Typical converted steering control unit (AA) six point bolts (BB) Ground steel end cap (C) Gerotor outer ring (D) Gerotor star (EE) Spacer (F) Metering body (GG) New round section o-ring
Install round cross section o-ring (GG) in groove of metering body (F.)
Install round cross section o-ring (GG) in groove of spacer (EE)
Install spacer (EE) with o-ring (GG) facing away from metering body (F)
Install gerotor outer ring (C) with o-ring (GG) facing away from metering body (F) Note: If, the gerotor star (D) has a full length spline you can turn the spline with the outer ring. If the star has a partial spline, turn the outer ring only.
Install round cross section o-ring (GG) in the groove of gerotor outer ring (C)
Install ground steel end cap (BB) with new, self sealing cap screws (AA)
Use a six point (E10) Torx drive to dry torque all seven bolts (AA) to 14.12 2.83 N m (10.41 2.09 lb ft). Then final torque to 28.25 2.83 N m (20.83 2.09 lb ft) in the sequence that is numbered 1 through 7 in the magnified view of illustration 2Shaft Seal Replacement For Low Input Torque Steering Units
Illustration 3 g02084883
Standard input torque steering control unit. (K) Shaft seal (P) Seal gland bushing without groovesNote: The shaft seal for this unit has not been replaced.
Illustration 4 g02085213
Low input torque steering control unit (M) Former three piece shaft seal (N) New one piece shaft seal (T) Grooves in seal gland bushingTo determine low or standard torque, examine the seal gland bushing for grooves. Grooves identify low torque units.Note: The new shaft seal for the former (low torque) metering pump groups, is included with the seal kit listed in the chart.
