The ATC 85109245 Crankshaft Turning Barring Tool (also known as a cranking adapter) is designed to allow controlled rotation of the crankshaft from the front of the engine. It provides a safe and reliable method for manually turning the engine during service, maintenance, timing adjustments, inspection, or alignment procedures. This tool is commonly used on Volvo D11 and D13 engines as well as Mack MP7 and MP8 platforms.
Because it engages the crank pulley or front housing, the 85109245 adapter helps prevent slippage while allowing precise engine rotation. This level of control is critical for tasks such as setting engine timing, installing camshafts, checking piston positions, and verifying engine balance during service procedures.
Key Features & Benefits
- Engineered for Volvo & Mack engines: Compatible with Volvo D11, D13 and Mack MP7 / MP8 platforms.
- Allows front-engine crankshaft rotation through the crank pulley or adapter mounting point.
- Enables safe and precise manual engine turning without using the starter motor.
- Durable construction designed for repeated use in professional repair environments.
- Ideal for mechanics, engine rebuild shops, fleet service facilities, and heavy equipment maintenance.
Typical Applications
- Manual engine rotation during cylinder head service, timing gear installation, or camshaft alignment.
- Inspection of piston positions or compression stroke during engine teardown.
- Verification of Top Dead Center (TDC) or camshaft phasing during engine service.
- Controlled crankshaft rotation to prevent damage from improvised turning methods.
Usage & Compatibility Notes
- Ensure the adapter is properly seated in the crank cover, pulley hub, or mounting point according to OEM procedures.
- Rotate the engine slowly and incrementally; avoid applying excessive torque.
- Always confirm vehicle and engine compatibility before use.
- Store the tool carefully to protect alignment surfaces from wear or damage.
