Sunluway Honda/Acura Crank Pulley Tool Kit — 19mm Counter-Weighted Socket & 50mm Pulley Holder for 1/2" Drive

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

This compact removal kit gives DIYers and professional mechanics a focused solution for stubborn crankshaft bolts and rotating pulleys. The set includes a deep, counter-weighted 19mm socket designed for impact tools and a hex-shaped 50mm pulley holding spanner that accepts a 1/2" square drive. Together they stop pulley rotation and deliver concentrated torque so bolt removal and installation are faster, safer, and less likely to damage the damper or surrounding components.

How does the 50mm pulley holder prevent the crank pulley from turning?

The 50mm holder fits the crank pulley profile with a hexagonal interface that resists rotation when torque is applied. It is used with a 1/2" drive ratchet or breaker bar to lock the pulley in place, so the bolt can be loosened or tightened without the engine turning over.

• Hex-shaped 50mm design matches common Honda pulley flats for secure contact
• Works with 1/2" square drive hand tools and breaker bars
• Prevents engine rotation that could damage timing components

Why is the 19mm socket counter-weighted and how does that help?

The 19mm socket is deeper and carries extra mass distributed for counter-weighting, which reduces energy losses from impacts. Using an impact wrench, the heavier socket transfers more force to the bolt, increasing the chance to break seized crank bolts free while minimizing repeated tool slip.

• Deep, heavy construction concentrates impact energy into the bolt
• 6-point contact profile for improved grip and reduced rounding
• Optimized for 1/2" drive impact tools to handle high torque loads

Which Honda and Acura engines is this kit compatible with?

The kit targets models that use a 19mm hex crank bolt and a 50mm pulley interface—commonly found across many modern and legacy Honda/Acura engines. Always compare the pulley diameter and bolt head size on your vehicle before purchase to confirm fitment.

• Designed for Honda and Acura engines with 19mm crank bolt heads
• 50mm holder fits pulleys with matching flats or hex-style profiles
• Compact kit suits both home garages and professional shops

How do I use the kit safely during removal and installation?

Start by seating the 50mm holder on the pulley and secure it with a 1/2" drive tool to stop rotation. Use the counter-weighted 19mm socket on an impact or breaker bar to remove the crank bolt; reverse steps for installation, torquing to factory specs. Wear eye protection and follow vehicle service manual procedures.

• Seat the holder fully, then brace with a ratchet or bar before impacting the bolt
• Use proper torque specs for reinstallation to avoid under- or over-tightening
• Inspect pulley and damper for wear before reuse

Who this is for: This Sunluway kit is for automotive technicians, serious DIY mechanics, and Honda/Acura owners who need a dedicated, reliable toolset for crank pulley and bolt service. It suits anyone repairing or replacing timing belts, pulleys, or performing front-end engine work where controlling pulley rotation and breaking sealed crank bolts are required. Backed by a 30-day return promise and one-year limited warranty, the set is built to withstand repeated use in home and shop environments.
