Lisle Camshaft Lock Tool for Honda K-Series K20 K24 — Single-Piece USA-Made, Pulse Plate Fit

This compact tool is engineered to insert into the camshaft pulse plates and hold the cams in a fixed position while you service timing chains, replace tensioners, or perform valve timing checks on K20 and K24 engines. Made in the United States and supplied as a single-piece unit, the Lisle 37950 simplifies otherwise fiddly alignment work and reduces the risk of cam movement during reassembly.

How does the Lisle 37950 help when replacing a timing chain?

It prevents the cams from rotating once the head and timing components are loosened, so you can remove and install the chain while the camshafts remain accurately indexed. The tool's pins engage the pulse plate openings to hold position reliably.

• Engages pulse plate holes on K20/K24 camshafts for positive lock
• Maintains cam alignment during chain removal and installation
• Saves time by avoiding repeated timing checks
• Reduces chance of incorrect reassembly or valve interference

Will this fit my Honda K-Series engine camshafts?

The Lisle 37950 is made specifically for Honda K-Series (K20 and K24) cam pulse plates and aligns with the factory pulse-plate pin locations. It is not intended for non-K-Series designs or camshafts that use different pulse plate geometries.

• Compatible with K20 and K24 engine pulse plates
• Designed for OEM-style pulse plate openings
• Not universal — verify your engine is a K-Series before purchase

How do I use the camshaft lock tool safely and effectively?

With the engine at the proper service position, rotate the cams to align the pulse plate openings, then insert the tool's pins into those openings to lock the camshafts. Always follow the manufacturer's service manual procedures and secure the vehicle before working.

• Bring engine to specified cam position per service manual
• Insert tool pins fully into pulse plate openings to lock cams
• Double-check timing marks before disassembly
• Remove tool only after timing components are secured and checked

What are the tool's size and origin details?

The Lisle 37950 ships as a single unit in compact packaging and is produced in the United States. Its slim profile and precise pin dimensions match K-Series pulse plates while keeping storage and transport simple.

Who is this for? The Lisle 37950 camshaft lock tool is aimed at mechanics, DIY enthusiasts, and performance builders who work on Honda K-Series engines and need a simple, reliable method to lock camshafts during timing-chain service or valve-timing adjustments. If you perform routine timing maintenance or engine rebuilds on K20 or K24 motors, this tool reduces rework, saves time, and helps maintain correct cam alignment throughout the repair process.
