The 121 entries group into 22 distinct number series, led by YN30V, LQ30V. In practice that means repeated items such as ring, spring, valve and 20 hardware positions.

The high-quantity positions are: ZS23C08025 (capscrew, ×40 per assembly); 2436U1443S332 (spring, ×26 per assembly); ZD12G03000 (o ring -, ×21 per assembly). The full list follows below.

Working from the exploded view is the fastest way to order. Find the component on the drawing, note its callout number, and take the matching reference from the table — that mapping removes the guesswork that comes with describing a part over the phone or in an email.

For workshops planning a full hydraulic health check, the practical sequence is seals first, then wear items such as valve plates and bushings, and only then complete assemblies. The table below supports that sequence because every level of the breakdown is separately orderable.
