(1) Inspect the track links and grousers for

cracks, breaks, and distortion. Repair or replace

broken or damaged links and grousers.

(2) Refer to table 1-5 for track pin and

bushing wear tolerances.

(3) Inspect the track links for wear. When the

links are worn from 4.57 to 4.38 inches in height,

they will be repaired by welding an overlay on the

wear surface. Links worn 4.38 inches or less in

height will be replaced. Link height new is 4.75

inches.

Pin boss clearance new is 0.69 inch. Acceptable

pin boss clearance is 0.35 inch.

repaired by installing applicator bars. Grousers

worn to a height of less than 1 inch, or grousers

uneconomical to repair, will be replaced. New

grouser height is 2.56 inches. Applicator bars will

be installed one time only.
