Camoo 19mm Harmonic Balancer Socket & 50mm Crank Pulley Holder Kit — Heavy-Duty 1/2" Drive for Honda & Acura Engines

Camoo's two-piece heavy-duty kit pairs a 19mm impact harmonic balancer socket with a 50mm crank pulley wrench holder to safely hold and remove crankshaft pulley bolts on many Honda and Acura engines.

This specialized removal tool set is built for the torque and fitment demands of Honda/Acura crankshaft bolts and harmonic dampers. The kit includes a reinforced 19mm impact socket engineered with extra mass to transfer more energy, and a hardened chrome-moly 50mm pulley holder that secures the damper while you loosen or tighten the crank bolt. Both pieces are designed to work with 1/2" drive impact tools and hand sockets, making them practical for professional mechanics and DIY enthusiasts tackling engine service, timing belt jobs, or pulley replacements.

Which engines and fasteners is this kit compatible with?

The set targets Honda and Acura applications that use a 19mm hex crank bolt and a 50mm-style pulley flange. It fits many common B-series, K-series and other Honda engine crank pulleys where a 50mm holder can engage the pulley recess.

• Designed for Honda/Acura crankshaft pulley bolts with 19mm hex heads.
• 50mm pulley holder engages flanged harmonic dampers commonly found on these engines.
• Works with standard 1/2" drive ratchets and impact wrenches.

How does the design reduce bolt removal failures?

The 19mm impact socket is heat-treated alloy steel with significantly increased mass to concentrate impact energy into loosening stubborn crank bolts. The 50mm holder locks the damper so the socket can deliver torque without the pulley rotating.

• Heavy-duty socket mass channels more force to the bolt head for efficient removal.
• Chrome-moly pulley holder resists wear and keeps a firm grip on the damper.
• Offset and engagement geometry tailored for clearance around timing covers and brackets.

What materials and durability features are included?

Both tools use premium materials chosen for repeated impact and workshop use. The pulley holder is forged from hardened chrome-molybdenum steel for anti-wear performance, while the socket is made from heat-treated impact-quality alloy steel to withstand high torque impacts.

• Hardened chrome-moly construction on the holder for longevity.
• Heat-treated impact alloy steel socket resists cracking under impact.
• Finish and tolerances made to shop-grade standards for repeated service.

How should I use the kit safely and effectively?

Use the pulley holder to immobilize the harmonic damper before applying an impact or breaker bar to the 19mm crank bolt. Always secure the vehicle, follow manufacturer torque specs on reassembly, and use appropriate safety gear when working under the vehicle.

• Engage the 50mm holder on the damper, then apply the 19mm socket to the crank bolt.
• Use a 1/2" drive impact wrench or breaker bar; avoid excessive side-loading.
• Replace worn fasteners and follow OEM torque for reinstallation.

Who this is for: automotive technicians, weekend mechanics, and Honda/Acura owners who perform timing belt changes, front-end engine service, or harmonic balancer/pulley replacement will value this kit. It’s aimed at users who need a durable, application-specific solution to prevent rounding crank bolts and to make crank pulley removal and installation quicker and safer. Camoo backs the set with a 30-day return policy and a 12-month warranty for added confidence.
