14MM Top Dead Centre Finder Tool – Stainless Steel with Measurement Scale

Brief Overview

This 14mm top-dead-centre (TDC) finder is an essential diagnostic and timing tool for any professional shop working with small-to-medium displacement engines. As you rotate the engine by hand or crankshaft, the piston rises into the tool's center indicator, allowing you to identify TDC instantly and accurately. The graduated hex shank provides additional precision for recording exact piston positions during engine diagnostics or timing adjustments. Pair this with a compatible spark plug adapter for seamless installation across multiple engine types.

Key Features

• Fast TDC Detection: Visual confirmation as the piston rises—eliminates guesswork during engine rotation
• Universal 14mm Fitment: Compatible with all standard 14mm spark plug holes
• Stainless Steel 304 Construction: Corrosion-resistant, durable, and safe for repeated use in high-humidity workshop environments
• Graduated Measurement Scale: Etched linear markings on the hex shank allow precise documentation of piston position and stroke length
• Ergonomic Diamond-Knurled Grip: Secure, non-slip handling during engine rotation
• Multi-Start Threaded Collar: Ensures quick, hand-tight installation without cross-threading
• Black Rubber O-Ring Seals: Protects against minor oil seepage and vibration during use
• Hex Shank Design: Allows use with a ratchet or wrench for hands-free positioning in confined engine bays

Why Resellers Choose This Tool

High-Margin Consumable Diagnostic Aid: TDC finders are regularly purchased by independent shops, fleet maintenance operations, and technical training centers. Low cost-per-unit, repeatable orders, and zero product liability make this a low-risk, profitable stock item.

Essential for Timing and Valve Service: Every engine overhaul, timing belt replacement, or valve adjustment requires TDC confirmation. This positions your shop as the trusted supplier for foundational diagnostic equipment.

Durability = Repeat Orders: Stainless steel construction ensures these tools last years, but shops maintain backup units. Build customer loyalty through consistent availability.
