Measuring method of Track Link Pitch(Service Bulletin KORK112) Calculation of track link wear

S01902C

•

Track link wear = (Pitch of four track links / 4) I-nitial track link pitch.

•

% of wear = [Track link wear / (Repair limit -Initial track link pitch)] x 100.

•

Remaining life (%) = 100 - Rate of wear (%)
