6. Check the backlash between pinion (04) and the vertical
made by means of the shims located beneath the vertical
swing shaft bearing retainers (see Subsection 6D).
7. Check the bevel pinion gear contact, using a thin coat-
ing of Prussian blue or white lead on one gear. Rotate the
gears together under no load to determine contact on the
tact condition as shown.
8. Lubricate the assembly with multipurpose grease
through fitting (12).
NOTE
Fitting (11) is a relief fitting. When grease backs up
through the relief fitting, stop adding lubricant. Be
careful not to overlubricate fittings (12) since dam-
