Reference: For instruction on reusability, refer to Guideline For Reusable Parts, SEBF8022, "Sealed And Lubricated Track".

Maximum track press assembly force ... 710 kN (160000 lb)

(1) Apply 4C-5592 Anti-Seize Compound to the threads and the washer face of each bolt that holds the half links together.

Torque for these bolts ... 340 ± 70 N·m (250 ± 50 lb ft)

Tighten the bolts by an additional 180 degree turn.

(2) Apply SAE 30W oil to the bolt threads and the washer faces that hold the track shoes to the track links.

Torque for these bolts ... 340 ± 70 N·m (250 ± 50 lb ft)

Tighten the bolts by an additional 120 degree turn.

Note: Install the nuts so that the radii on the corner of the nut are against the track link.

(3) Original height (grouser) for extreme utilization ... 71.5 mm (2.81 inch)

Original height (grouser) for moderate utilization ... 70.0 mm (2.76 inch)

Note: The dimensions of the grouser are not applicable to self-cleaning track shoes.

(4) Height of an unused track link ... 139.9 mm (5.5 inch)

(5) Distance from the center of one pin to the center of the next pin (pitch) ... 215.9 mm (8.500 inch)

(6) Extension of pin at each end for power shift machines and for direct drive machines ... 4.9 ± 0.8 mm (0.193 ± 0.032 inch)

(7) Bushings

Diameter of an unused bushing ... 79.16 ± 0.25 mm (3.117 ± 0.010 inch)

(8) Thickness of an unused thrust ring ... 10.70 ± 0.08 mm (0.421 ± 0.003 inch)

(9) Distance from the face of the track link to the end of the bushing ... 1.80 ± 0.13 mm (0.071 ± 0.005 inch)

(10) Maximum permissible end clearance (end play) ... 0.20 mm (0.008 inch)
