Read as a dataset, the 12 part numbers spread across 7 number series (LQ54D, YN70V, ZP26D being the biggest) In practice that means repeated items such as pin, spring, idler and 1 hardware positions.

Three numbers worth noting first: LQ54D01023P1 (pin, ×2 per assembly); YN70V00004F2 (cylinder assy,grease, ×1 per assembly); LQ54D01013P1 (bracket, ×1 per assembly). The full list follows below.

Rebuilding a joint takes the machine out of service once, so it pays to consolidate: pins, bushings, retaining rings and the joint seals quoted together, arriving as one kit rather than in several parcels.

Undercarriage and structural wear is progressive: play at a joint, a knocking sound on direction change, oval wear on a pin. Because each position carries its own part number, worn positions can be replaced individually instead of ordering the complete group.
