bolts will rupture. Therefore the loosened bolts should be
fastened.
Tightening method
Track shoe
1) Tighten at torque 490 ± 49 N m (50 ± 5 kgf m, 360 ± 36
lbft), then check to make sure that nuts contact with track
link surfaces securely.
2) After checking, retighten 120° ± 10°.
Rubber block ( if mounted)
1) Tighten at torque: 549 ± 59 N m (56 ± 6 kgf m, 405 ± 43
lbft).
2) After tightening, check to ensure that nut and track link
contact surface contact against each other securely. .
Tighten Sequence
Tighten bolts in the sequence given in right fig.
