Description

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

  • Crankshaft pulley locking tool – Secure crankshaft position during timing work
  • Balance shaft locking fork and rod – Dual-component balance shaft immobilization for precise alignment
  • Camshaft locking plate – Multi-point contact design locks both camshafts simultaneously
  • Bridge tool for timing chain installation – Guides chain routing during reassembly
  • Timing gear alignment guide – Ensures sprocket bore and timing mark alignment
  • Offset E14 1/2″ wrench – Specialized socket for tight-access fasteners, particularly on Sprinter models
  • Precision-machined steel components – Brushed finish, stamped identification marks for accurate positioning
  • Molded blue plastic carrying case – Organized storage with shaped cavities for each tool; includes latching mechanism and instruction label

Business Advantages for Resellers & Shop Owners

  • High-volume application base: Covers 20+ Mercedes-Benz model lines and sub-variants spanning 2008–2020, ensuring strong customer demand
  • Diagnostic & preventive value: Timing misalignment is a leading cause of expensive engine rebuilds; accurate locking tools justify premium labor rates
  • Recurring service revenue: Timing chain service intervals repeat across fleet vehicles; establish this as a core shop service
  • Competitive positioning: Shops without proper timing tools outsource this work; owning this kit positions you as a full-service diesel specialist
  • Bulk order incentive: Suitable for multi-shop operations, fleet maintenance facilities, and authorized dealer networks

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.
