On a new track chain, the track shoe bolts must be checked after the first 10 hours of operation or
until it becomes evident that the shoes have become permanently set (Fig. 15.2). Check if the bolts
are tightened to 1100 [Nm]. If not, strike the heads of the bolts several heavy blows with
a hammer when retightening them.
NOTE: If tight loosen or removed shoe bolt torque the one to 650 ± 70 [Nm] + 120 [°] of turn.
CAUTION! As a safety measure, use goggles to protect your eyes while striking
bolts.
IMPORTANT: Do not use common bolts in the track shoes.

Fig. 15.3. Removing Split Link

slack in chain. To insure that there is no pressure against the idler, pry the front
idler and fork back away from the front idler stops.
