Blade Shank Inspection and Machining Standards

Detailed dimensional tables and cross-sectional diagrams govern the inspection of single shoulder (Y-shank, D-shank, E-shank, M-shank, P-shank, R-shank, T-shank, W-shank, Z-shank, and MV-shank) and double shoulder (X-shank and V-shank) designs. The manual defines exact caliper and micrometer measuring points, allowable undercutting limits, minimum shoulder heights, lip thicknesses, and runout tolerances. Clear procedures detail cold compression rolling of single-shoulder retention radii using approved rolling equipment, electronic profilometer surface finish measurements (10 to 15 Ra microinch standards), optical comparator overlay verification, chemical etching, and penetrant inspection guidelines.

Pitch Change Knob and Balance Hole Refurbishment

Specific sections detail the repair, perpendicularity inspection, and shot peening of F-type and non-F pitch change knobs on Y-shank blades, complete with Almen A strip intensity verification, nozzle angle setup, and masking instructions. Internal blade shank overhaul instructions cover bearing removal, lead extraction via high-pressure water jet or modified drill tooling, balance hole reaming, bore critical-area inspection, chemical conversion coating, protective Polane painting, and precision blade bushing installation and reaming.

Counterweight Maintenance and Insert Repairs

The manual provides thorough procedures for counterweight disassembly, bolt replacement, magnetic particle inspection, dowel pin hole inspection, and press-fit installation of standard and oversized dowel pins (A-65, B-6260, 100332, 104073, 104074). Detailed machining steps guide the repair of damaged counterweight knob tapped holes (7/16-20 and 1/2-20) using staked inserts (B-6143 series) and thin wall inserts (B-6986-258M) mounted on expanding arbor fixtures.
