12-3. DRIVE WHEEL SPINDLE REPLACEMENT/ADJUSTMENT (CONT)

(3)

Adjust vertical end play.

(a)

Remove upper and lower drive wheel spindle caps. Measure total current shim pack thickness

(upper and lower shim packs combined).

(b)

Subtract actual end play (value obtained in Step (1)) from total shim pack thickness obtained

in Step (2)(a). Divide this result by two.

(c)

Make new lower shim thickness the same value as calculated in Step (2)(b). If this thickness

cannot be met exactly, choose nearest thicker shim pack.

(d)

Make new upper shim thickness the same as value obtained in Step (2)(b), plus 0.005 in.

(0.13 mm). If this result cannot be met exactly, choose nearest thicker shim pack.

NOTE

Follow-on Maintenance: Install planetary wheel ends (Para 8-6 or Para 9-6).
