2. VALVE ASSEMBLY
1) Remove traces of sealer, oil, rust, etc., from mating
surfaces of valve housing and steering body.
2) Position a shim in graded portion of steering body pin-
ion housing, and apply an even coat of sealer (Fuji Bond
C: 004403004 or three bond 1105 (00440310) or equiva-
lent) to end of pinion housing.
3) Use the same number of shims as that used when
steering body was removed.
4) If steering body, valve housing or pinion and valve is
replaced with a new one, add two or three shims, install
valve on pinion housing and tighten with two bolts to 25±5
N⋅m (2.5±0.5 kg-m, 18.1±3.6 ft-lb). Then, measure clear-
ance between steering body and valve housing using a
thickness gauge. Remove shims so that the clearance is
zero.
