SECTION 5 - BASIC HYDRAULIC INFORMATION & HYDRAULIC SCHEMATICS

7. Prepare the gears.

THE GEAR SURFACES ARE SUPER-FINISHED. RESIDUE ON HANDS AND FIN-

GERS MAY BE CORROSIVE TO THIS SURFACE. DO NOT TOUCH.

Carefully clean the two gears. If the gears are new, wash

them with shop solvent to remove any anticorrosive

grease on the surfaces.

Inspect the journals and the flat faces on the top and

bottom of the gears. Ensure these surfaces are free from

burrs or scratches. If scratches or burrs are found, clean

them with a flat stone and/or very fine emery paper.

Rewash the gears after this operation.

8. Prepare the bearing blocks.

Clean the two bearing blocks.

Inspect the flat surfaces of the bearing blocks for burrs

or scratches on the edges. If necessary, remove burrs

with very fine emery paper. Then rewash the bearings.

Inspect the DU bushings for wear. There should be no

bronze showing.

Using clean hydraulic oil, lubricate the internal and

external surfaces of the bearing blocks.
