C: INSPECTION
1) Clean all disassembled parts, and check for
wear, damage, or any other faults, then repair or
replace as necessary.2) When disassembling, check inside of gearbox
for water. If any water is found, carefully check boot
for damage, input shaft dust seal, adjusting screw
and boot clips for poor sealing. If faulty, replace
with new parts.
No. Parts Inspection Corrective action
1 Input shaft(1) Bend of input shaft
(2) Damage on serrationIf bend or damage is excessive, replace
entire gearbox.
2 Dust seal(1) Crack or damage
(2) WearIf outer wall slips, lip is worn out or damage
is found, replace it with new one.
3 Rack and pinion Poor mating of rack with pinion(1) Adjust backlash properly.
By measuring turning torque of gearbox
and sliding resistance of rack, check if rack
and pinion engage uniformly and smoothly
with each other.
(Refer to ªService limitº.)
(2) Keeping rack pulled out all the way so
that all teeth emerge, check teeth for dam-
age.
Even if abnormality is found in either (1) or
(2), replace entire gearbox.

(2) Bend of cylinder portion
(3) Crack or damage on cast iron portionReplace gearbox with new one.
(4) Wear or damage on rack bushIf free play of rack shaft in radial direction is
out of the specified range, replace gearbox
with new one. (Refer to ªService limitº.)
(5) Wear on input shaft bearingIf free plays of input shaft in radial and axial
directions are out of the specified ranges,
replace gearbox with new one.
(Refer to ªService limitº.)
