Read as a dataset, the 27 part numbers spread across 3 number series (YN03M, ZM73C, YN50S being the biggest) Expect repeated items such as bolt, ring, retaining and 10 hardware positions when you work through it.

The high-quantity positions are: ZM73C08020 (sems-bolt, ×6 per assembly); YN03M01914P1 (ring,retaining, ×3 per assembly); YN03M01916P1 (ring,retaining, ×2 per assembly). The full list follows below.

Controls wear with use: levers develop play, linkages tighten up, and pilot circuits drift. Because each component in this group carries its own part number, worn positions can be replaced individually and the machine keeps its original feel.

Pilot and control-line items in this group carry hydraulic pressure, so their seals are service items rather than lifetime parts. Including fresh seals with any linkage order avoids a second stoppage later.
