Maintaining the UH-60 Blackhawk main rotor system requires more than just skill—it demands precision tooling to ensure safety, compliance, and fleet readiness. At Specialized Tool and Supply, our Main Rotor Tool Kits (HMR series) are engineered to deliver exactly that. These kits combine specialized, Army-compliant tools designed to cut downtime, reduce risk, and prevent costly component damage. The kit is available for quick procurement through GSA Advantage.
Why Specialized Main Rotor Tool Kits Matter
Standard procedures often rely on improvised tools or outdated methods, creating risks to safety, mission readiness, and component longevity. Our purpose-built tools directly address these issues, providing:
- Significant labor savings by reducing maintenance hours.
- Cost avoidance by preventing hub, spindle, and bearing damage.
- Safety improvements for maintainers working on flight-critical hardware.
Key Tools in the Main Rotor Kits
HMR-SPEX-1 – Main Rotor Spindle Extractor
Traditional methods call for pry bars, hammers, and sealant removal, taking 1–2 hours per spindle and creating FOD hazards.
- Benefit: Reduces removal to 2–3 minutes.
- Safety: Built-in strap prevents an 80+ lb spindle from dropping.
- Cost Savings: Prevents hub liner and spindle lug damage, eliminating expensive hub replacements.
HMR-DSPS-1 – Damper Spherical Bearing Press
IETM procedures require an Arbor Press, forcing maintainers to remove the entire damper assembly.
- Benefit: Removes/replaces bearings without damper removal.
- Labor Reduction: No Arbor Press needed, saving hours of work.
HMR-SBWAS-1 – Spindle & Blade Washer Aligner Set
Blade and spindle cuff washers are often knocked off during removal or folding, requiring time-consuming re-bonding.
- Benefit: Precisely bonds washers with dual pressure plates.
- Safety: Prevents misalignment and washer pop-off.
- Efficiency: Bonds all cuffs simultaneously during 24-hour curing.
HMR-SBPS-1 – Spindle Bearing Press Set
Locally made presses often lack proper sleeves or stands, risking elastomeric bearing damage.
- Benefit: Re-engineered stainless steel press with stand.
- Cost Savings: Protects conical elastomeric bearings in the field.
HMR-SWSB-1 – Swashplate Scissor Bearing Press
Provides the precision and fit needed to safely remove and install swashplate scissor bearings.
- Benefit: Prevents component damage from incorrect pressing methods.
HMR-PCTA-1 – Pitch Change Rod Torque Adapter
Engineered to torque pitch control rod bolts to exact specifications.
- Benefit: Ensures compliance with Army torque requirements.
HMR-BSBF-1 – Bifilar Weight Bolt Fixture Set
No standard Army tool exists for bifilar bolt torqueing, leading to costly mistakes.
- Benefit: Braces bifilar bolts for proper torque.
- Cost Savings: Prevents bifilar arm damage.
- Efficiency: Improves torqueing accuracy and speed.
HMR-BADJ-1 – Blade Adjustment Tool
Improvised alignment tools often slip, damaging the fiberglass fairing.
- Benefit: Ergonomic grip eliminates slip-through.
- Safety: Prevents drop damage during alignment.
HMR-STA-1 – Spline Low Profile Torque Adapter
Performs torque checks on spindle bolts beneath the anti-flap stop.
- Benefit: Allows 9–11 torque checks without disassembly.
HFC-FCBP-1 – Flight Control Bearing Press
Rigging issues are often traced to faulty bearings, but no standard tool exists.
- Benefit: Identifies faulty bearings during rigging.
- Cost Savings: Prevents failed inspections and rework.
- Labor Reduction: Saves hours during aircraft rigging.
Other Kit Tools Include:
- HMR-LPS-1 – Lower Pressure Plate Bolt Socket (9/16″): Compact design for tight access.
- HMR-RNE-1 – Main Rotor Retaining Nut Drive Extension: Assists in Zone 1 hardware torque checks.
- HMR-CFW-1 – Crowfoot Wrench Set, 3/8 Drive: Versatile torqueing in confined spaces.
- HMR-SWD-1 – Collective Balance Spring Socket: Safe removal/installation of balance spring hardware.
- HMR-PCLK-1 – Pitch Control Link Tool: Aligns elastomeric bearings on PC rods.
- HMR-TIKSH-1 – Threaded Insert Kit (Spindle & HSS): Provides reliable threaded insert replacement capability.
