The ATCW936589014000 Crankshaft Holding Tool is a precision service tool designed to secure and hold the crankshaft in position on Detroit Diesel DD5 engines during critical service procedures.
On DD5 platforms, many operations require the crankshaft to remain completely stationary to maintain proper timing and prevent component movement. This tool engages with the flywheel or crankshaft holding points, providing a solid mechanical lock that prevents rotation while work is performed.
It is commonly used during:
- Flywheel and flexplate removal or installation
- Crankshaft bolt loosening and tightening
- Timing and synchronization procedures
- Engine disassembly and reassembly
Unlike improvised methods, the ATCW936589014000 provides secure, positive engagement, reducing the risk of slipping or damage to flywheel teeth and surrounding components.

- Designed for Detroit Diesel DD5 engines
- Securely holds crankshaft in fixed position
- Prevents rotation during high-torque operations
- Protects flywheel and gear teeth from damage
- Improves safety and control during service
- Application-specific fit for proper engagement
- Heavy-duty construction for professional use
Typical Applications
- Crankshaft holding during bolt removal/installation
- Flywheel and flexplate service
- Engine timing and alignment procedures
- Engine teardown and assembly
- Heavy-duty diesel maintenance
Why It Matters
Crankshaft movement during service can lead to:
- Incorrect timing alignment
- Difficulty loosening or tightening fasteners
- Potential damage to internal components
The ATCW936589014000 ensures the crankshaft remains securely locked, allowing technicians to perform work accurately and safely.
