PREMATURE WEAR/FAILURE OF FRONT DIFFERENTIAL COMPONENTS - continued

TM 10-3930-673-34

WARNING

Differential and ring gear weigh 100+ lbs (45.4 kg). Attach

suitable lifting device prior to removal to prevent

possible injury to personnel.

No-spin differential contains compression springs

under pressure. Failure to use a retaining bolt or other

means of restraint can cause injury to personnel

when removing no-spin differential.

Use care when removing snap and retaining rings.

Snap and retaining rings are under spring tension

and can act as projectiles when released, and could

cause severe eye injury.

Compressed air used for cleaning purposes will not

exceed 30 psi (207 kPa). Use only with effective chip

guarding and personal protective equipment (goggles/

shield, gloves, and so forth).

Adhesives, solvents, and sealing compounds can

burn easily, can give off harmful vapors, and are

harmful to skin and clothing. To avoid injury or

death, keep away from open fire and use in a well-

ventilated area. If adhesive, solvent, or sealing

compound gets on skin or clothing, wash

immediately with soap and water.

CAUTION

Wipe area clean around all hydraulic connections to be

opened during removal. Cap oil lines and plug holes after

removing lines. Contamination of the hydraulic system

could result in premature failure.

Ring gear must be heated before installation. Failure to

heat ring gear before installation could cause damage

to differential case half because of tight fit.

Spacing between four initially installed

screws must be even to prevent uneven pressure on case

halves when torquing. Failure to do so could cause

component failure.

VISUAL INSPECTION

(1) Remove differential carrier assembly

from differential housing (Para 8-5).

(2) Visually inspect housing and assembly

for signs of dirt and debris.

(a) If housing and assembly are clean,

go to Step 2 of this fault.

(b) If housing and/or assembly are

dirty, disassemble carrier assembly

and clean both housing and
