Our component / drawing revision: [ ]
Assembly and mating interfaces: [ ]

Please review:
1. Pin drawing and mating-bushing definition
2. Purpose of the axial bore and cross hole
3. Retention and working-load validation scope
4. Material, surface, quantities and sample approval requirements

Sample acceptance to agree:
1. Working journal: Define mating clearance, contact length and the final measurement condition.
2. Bore and cross hole: Locate the intersection and specify the required internal edge condition.
3. Retention interface: Identify the shoulder or separate retaining feature and the assembly stack.
4. Surface protection: Identify sliding surfaces and packaging contact points.
