Moker Flywheel Turning Tool for Volvo & Mack 2008–2018 — Solid Steel, Black Powder Coat

Moker flywheel turning tool rotates the crankshaft on 2008–2018 Volvo D11, D13, D16 and Mack MP7, MP8, MP10 engines so you can set timing, change injectors, or perform overhead adjustments accurately and safely.

This heavy-duty crank barring tool is an aftermarket alternative to OEM part numbers 88800014 and 88840317, designed specifically for the common heavy-duty Volvo and Mack diesel engines used in fleets from 2008 through 2018. Built from solid steel with a black powder coat finish, the tool gives technicians a reliable, corrosion-resistant method to index the flywheel and rotate the crankshaft one tooth at a time during service. The design focuses on simple fitment, long-term durability, and safe leverage when positioning the engine for timing or component replacement.

How does this tool help when setting engine timing?

The Moker flywheel turning tool provides controlled rotation of the crankshaft so you can align timing marks and verify cam/crank positions without using the starter. It reduces the risk of over-rotation and makes incremental adjustments possible during precision timing procedures. Using the tool removes load from the starter and prevents accidental valve-to-piston contact that can happen with uncontrolled rotation.

• Enables step-by-step crankshaft indexing for accurate timing alignment
• Prevents starter use during timing checks, reducing electrical wear
• Stable engagement with flywheel teeth to avoid slippage

What are the construction and durability features?

The tool is fabricated from high-grade solid steel and finished with a black powder coat for improved corrosion resistance and surface hardness. Its robust build handles workshop torque and repeated use without deforming, maintaining accurate engagement with the flywheel over time. The coating also simplifies cleaning and reduces the chance of rust in heavy-use environments like fleets and repair shops.

How is the tool used safely in a workshop?

Use the Moker crank barring tool with the engine secured and ignition disabled to avoid accidental start. Engage the tool with the flywheel teeth and rotate slowly using a breaker bar or suitable wrench—never apply sudden or impact forces. Follow manufacturer service procedures for locking the engine and supporting rotating assemblies while working.

• Always disconnect the battery and disable the starter before use
• Engage tool fully with flywheel teeth for stable rotation
• Rotate slowly and use controlled leverage; avoid impact tools
