Timing Locking Tool Set for Mercedes-Benz M651 Diesel Engines – 1.8–2.2L Camshaft & Crankshaft Positioning
Brief Overview
This specialist timing locking tool set is purpose-built for timing chain replacement and camshaft sprocket service on Mercedes-Benz vehicles equipped with 1.8, 2.1, and 2.2L M651 diesel engines. The kit provides precise crankshaft, camshaft, and balance shaft locking during critical engine service—eliminating guesswork and reducing the risk of timing misalignment that can result in catastrophic engine damage.
For shops servicing a broad range of Mercedes diesel models (A-Class through Sprinter platforms), this kit is essential. Pair this with complementary camshaft chain adjustment tools for complete timing service coverage.
Key Features

Shop Integration & Service Workflow
This kit eliminates the need for improvised locking methods or multiple tool purchases. By locking the crankshaft, camshafts, and balance shafts simultaneously, technicians reduce timing service duration and eliminate human error in mark-up and re-installation.
Reseller Note: Pair this kit with complete engine timing alignment tools for other Mercedes platforms to maximize coverage across your customer base.
Value Proposition
Timing chain service is a high-labor, high-risk procedure. Shops that invest in purpose-built locking kits recover tool costs within 3–5 timing service jobs while building reputation for precision work. This kit is a differentiator in competitive markets and a revenue driver for independent and dealer service operations.
