Description

BMW N20/N26 Flywheel Holder – Timing Chain Service & Crankshaft Lock Tool

Brief Overview

This is a purpose-built flywheel locking tool designed specifically for N20 and N26 petrol engine service work. When paired with the complementary crankshaft alignment kit for N20/N26 engines, it provides comprehensive crankshaft and camshaft control during timing chain replacement, damper removal, and related top-end engine work. The tool securely locks the flywheel in position, preventing crankshaft rotation and allowing safe, controlled removal and installation of the central damper bolts. Essential for shops working regularly on BMW's modern four-cylinder petrol lineup.

Key Features

  • Cast metal housing with reinforced oval retention plate for secure grip on flywheel teeth
  • Dual hex-head mounting bolts with washers set into countersunk holes—engineered for repeatable positioning
  • Stepped engagement blade with precision-profiled cutouts designed to lock onto flywheel geometry
  • Fixed, non-articulating design ensures absolute crankshaft stability during high-torque damper work
  • Compact footprint allows access in tight engine bays typical of X1, X3, and sedan applications
  • Machined steel construction resists wear from repeated use across multiple vehicles

Business Advantages for Resellers

  • High demand consumable service tool: Timing chain service is a recurring revenue generator for independent shops and franchises working on 2012–2018 BMW inventory
  • Paired-tool model: Designed to be sold alongside the comprehensive timing control system for N20/N26 engines, increasing transaction value
  • OEM specification compliance: Part number 83 30 2 222 742 ensures shops trust the tool for factory-correct procedures
  • Low defect rate: Passive mechanical design (no springs, no articulation) means minimal warranty exposure
  • Bulk margin opportunity: Shops stocking BMW service tools recognize this as essential—ideal for bundled service kit resale

Application Notes

This tool is designed to prevent crankshaft movement during critical timing chain operations. It engages the flywheel's machined surfaces and must be used in conjunction with the complementary crankshaft control apparatus (referenced as A-N2026 in factory documentation) for complete engine immobilization.

Typical shop application:

  1. Lock crankshaft with this flywheel holder before breaking central damper bolts
  2. Install the camshaft lock to secure valve timing reference
  3. Remove and replace timing chain under controlled conditions
  4. Reverse the process for reinstallation with verified torque specs

Reseller Value Summary: A straightforward, single-function locking tool with strong OEM demand and no field failures. Stock this alongside your N20/N26 timing service kits for shops performing regular preventative maintenance on 2012–2018 BMW models.
