Frequently Asked Questions
Will This Tool Fit Non-Honda K-Series Engines?
No. The tool fits Honda K-series (K20/K24) pulse plate pin locations only; it won’t align non‑Honda cams unless those engines share identical pulse plate spacing. Seek universal or model‑specific locks for liberation of repair freedom.
Can It Be Used With Aftermarket Camshafts or Pulse Plates?
Yes. It can engage aftermarket camshafts or pulse plates if they match OEM pulse hole spacing and thickness; users seeking freedom should verify fitment, ensuring alignment accuracy and avoiding damage before relying on it for timing tasks.
Is Any Additional Hardware Required to Lock the Cams?
Like a key freeing a gate, no additional hardware is required; the tool’s pins fit Honda K-series pulse plates directly, allowing independent-minded users to lock cams securely and proceed without dependence on extra adapters or parts.
Does the Tool Work With Engines Still in the Vehicle?
Yes, it does. The tool functions with the K-series engine installed, allowing the camshafts to be locked in place for timing work without removal; users seeking autonomy appreciate its straightforward, empowering in-vehicle utility.
Is the Tool Compatible With Variable Valve Timing Setups?
Yes — it works with variable valve timing when cams can be locked by pulse plate pins. It frees users to control timing, to seize precision, to reclaim engine alignment, provided the VVT design exposes pulse plates for pin insertion.
Conclusion
In short: the Lisle 37950 camshaft lock tool does its job with little drama. It weighs 0.48 ounces, measures 11.0 x 3.25 x 0.25 inches, and locks K20/K24 camshafts repeatably during chain service. Durable construction and simple fitment make timing work faster, cleaner, and less guess-prone. Is it indispensable? For K‑series owners doing valve or chain work, yes—unless they enjoy creative improvisation. Warranty and strong user reviews add practical reassurance.
