screwing it into the cylinder housang.
Remove the C-clamp from the steering gearbox'
After tightening the cylinder end' stake the point of
the cylinder housing shown below For'98 -'00
models go to step 51.
NOTE: Stake the cylinder in the position opposite
from where the stake was removed during disas-
semoly.
Be careful not to damage
the bushing when inserting
the cylinder end.
49. Select the 32 mm shim(s) ('96 -'97 model only)'
NOTE: Only reinstall the original 32 mm shim(s)
when the steering gearbox is reassembled without
replacing the pinion shatt, valve housing, and gear
box housing with new ones.
lf the pinion shaft, valve housing, and gearbox
housing are replaced, select the new shim{s) as fol-
lows.
Shim selection:
a. Set the four 32 mm shims on the bearing surface of
the gearbox housing. Total thickness of the four
shims should equal no more than 0 70 mm'
Shim set: four 32 mm shims (Thickness: 010 mm'
0.15 mm, 0.20 mm, 0.25 mm respectivelyl
CAUTION: Th€ four 32 mm shims do not have
thickness identification marks Measure the thick-
ness of each shim using a micrometsr, and mark
the shim lor identification.

VALVE BODY UNTTFLANGE BOLT20 N.m {2.0 ksl.m, 14lbI.ftl
Measure the clearance between the gearbox andvalve body unit using a feeler gauge as shown.
NOTE: Measure the clearance at the point midwaybetween the two mounting bolts.
Determine the required thickness of the 32 mmshims by subtracting the clearance obtained in thestep "c" from the total thickness of the four shims.(Total thickness of the 4 shims) - (Clearance) =
Required thickness of the shims
NOTE: Select the shims so that the total thicknessis close to. but less than, the required thickness,

Example:
Measurement is 0.28 mm (0.011 in):0.70 - O.28 = 0.42 mm (0.028 - 0.011 = O.Ot7 inl
The selected shims should be 0.28 mm lO.OtO in) and0.15 mm {0.006 in} in thickness.
lf the r€quired shim thickness is 0.10 mm or less, noshims are necessarv.
