Read as a dataset, the 16 part numbers spread across 11 number series (YN64D, 2413N, 2418P being the biggest) The list is weighted toward repeated items such as roller, ring, upp and 5 hardware positions.

Where to start in this table: YN64D01068F1 (roller assy, ×4 per assembly); YN52F01100D3 (capscrew, ×4 per assembly); ZN13C20016 (nut, ×4 per assembly). The full list follows below.

Structural groups rarely fail as castings; what wears is everything pinned, bolted and clamped to them. That is what makes this group the practical one to work from — pins, bushings, retaining hardware and the mounting points that take the working load every cycle of the machine.

Structural repairs are usually planned against measured wear rather than a fixed interval. Pins and bushings are the items to measure first; the retaining hardware in this group is cheap to replace at the same time and is worth adding to the same shipment.
