gear teeth.

(3) If keyways are worn or enlarged, replace gear.

f. Bushings and Bushing-Type Bearings. When bushings and bushing-type bearings seize to a

shaft and spin in the bore, the associated part must also be replaced.

g. Oil Seals.

ASSEMBLY

a. Cleanliness is essential in all assembly operations. Dirt and dust, even in small quantities, are

abrasive. Parts must be cleaned as specified and kept clean. Wrap or cover parts and components when

assembly procedures are not completed immediately.

b. Lubricate all metal parts with lubricant used during operation. Refer to WP 0023 00 for proper

c. Installation of cotter pins and lockwires shall be accomplished as specified in assembly procedures.

d. Critical torque values are specified in the assembly procedure. When not specified, tighten bolts,

screws, and nuts in accordance with standard dry torque values (WP 0385 00).

e. All fuel, air, and hydraulic components must be kept thoroughly clean at all times. Plug all open

ports until the component is installed in the vehicle.

f. All pressing operations should be accomplished using a suitable press and adapters, unless otherwise

specified.

DISASSEMBLY

a. The work area for disassembly of any item must be kept as clean as possible. This will prevent

contamination of internal parts. This is especially true when working with fuel and air systems or CTIS

components.

b. All gaskets, O-rings, and seals removed during repair will be discarded and replaced with new parts.

These items are usually damaged during removal. Lockwire, lockwashers, locknuts, cotter pins, and like

items should be discarded during disassembly.

c. When removing gaskets, preformed packings, or seals, do not use any metal tool that will scratch the

sealing surface next to these items.

d. Before disassembling any item, study the illustration carefully, noting the relationship of internal

parts. Knowing the details of construction will speed up disassembly and help avoid mistakes.
