Read as a dataset, the 44 part numbers spread across 13 number series (LC12B, 2420T, B16T being the biggest) In practice that means repeated items such as shim, arm, pin and 6 hardware positions.

Three numbers worth noting first: 2445R220D6 (seal,dust, ×6 per assembly); ZG91S02000 (nipple,grease, ×5 per assembly); ZN18C20016 (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.
