15. Check the bull gear-to-air compressor drive gear lash measurement as follows:
[a] Mount a magnetic dial indicator base and dial indicator to the gear case cover so that
the stem of the dial indicator may be positioned on a tooth of the air compressor
drive gear.
[b] Preload the drive gear in one direction.
[c] Zero the dial indicator.
[d] Rotate the air compressor drive gear, read and record the total gear lash. Gear lash
measurements are 0.051-0.229 mm (0.002 -0.009 in.) for new parts, with a maximum
of 0.305 mm (0.012 in.) for used gears.
[e] If proper lash cannot be obtained, replace the gear with a new part. Refer to section
1.33.2.
[f] Remove the dial indicator and magnetic base.
[g] Install the power steering drive coupling to the air compressor drive gear (if equipped
with power steering) and insert a new O-ring on the power steering pump (if so
equipped).
[h] Install the power steering pump to the gear case cover, meshing the drive coupling
properly.
[i] Install and torque the power steering pump mounting bolts to 30-38 N·m (22-28 lb·ft).
Tighten the five bolts alternately and evenly, in a star-shaped pattern, to progressively
draw the power steering pump into the gear case cover.
NOTE:
Do not force the bolts. If resistance is encountered, remove the power steering pump
and re-engage the drive hub with the coupling.
[j] If the engine is not equipped with power steering, install the air compressor drive
gear access cover using a new gasket.
[k] Install and torque the retaining bolts to 30-38 N·m (22-28 lb·ft), using a star-shaped
pattern.
