Moker Flywheel Turning Tool for Volvo D11/D13/D16 & Mack MP7/MP8/MP10 (2008–2018) — Solid Steel, Powder-Coated

Moker's flywheel turning (crank barring) tool is a heavy-duty, aftermarket solid-steel wrench engineered to rotate the flywheel and crankshaft for Volvo D11, D13, D16 and Mack MP7, MP8, MP10 engines (2008–2018).

When servicing large diesel truck engines you need a dependable way to index the crankshaft precisely. This Moker tool gives technicians a secure, corrosion-resistant interface to turn the flywheel for timing checks, injector servicing, overhead adjustments, and any task that requires precise crankshaft positioning. It’s designed as a direct aftermarket alternative to OEM numbers 88800014 and 88840317 and fits the specified Volvo and Mack models produced between 2008 and 2018.

How does this tool help when setting engine timing?

The tool provides a positive engagement point on the flywheel so you can rotate the crankshaft in controlled increments without relying on starter torque. That stability lets you align timing marks and verify cam/crank relationships with confidence. Use it for manual rotation during timing belt or chain checks and for final alignment during reassembly.

• Engages the flywheel securely to prevent slipping.
• Allows slow, accurate crankshaft rotation for timing verification.
• Reduces risk of sudden movement compared to using starters or pry bars.

Will it fit my Volvo D13 or Mack MP8 from 2010?

Yes — the design targets the crank/flywheel interface used across Volvo D11, D13, D16 and Mack MP7, MP8, MP10 engines built from 2008 through 2018. It is made to match the engagement points and bolt patterns those engines share, making it a practical aftermarket substitute for the listed OEM part numbers.

• Compatible with Volvo D11, D13, D16 (2008–2018).
• Compatible with Mack MP7, MP8, MP10 (2008–2018).
• Listed as alternative to OEM 88800014 and 88840317.

What materials and finish does the barring tool use?

Built from solid steel for durability, the tool features a protective black powder coat that resists corrosion and everyday workshop wear. The robust construction helps maintain precise engagement over repeated service cycles and reduces deformation compared with lower-grade alternatives.

• Heavy-gauge steel body for strength and longevity.
• Black powder-coated surface for corrosion resistance.
• Manufactured to withstand workshop torque and repeated use.

What comes in the package and how do I use it safely?

Each purchase includes one complete flywheel barring tool ready for installation. To use, follow safe practices: block vehicle wheels, disconnect battery if required, and follow manufacturer procedures for accessing the flywheel. Insert and engage the tool per your engine service manual, then rotate deliberately using an appropriate leverage bar.

• Package contains one Moker flywheel barring/crank turning tool.
• Designed for manual rotation with a suitable breaker or lever bar.
• Always secure the vehicle and follow OEM safety steps before use.

Who this tool is for: Professional diesel technicians and experienced commercial-fleet mechanics who service Volvo and Mack heavy-duty engines, plus advanced DIYers maintaining trucks from 2008–2018. If you need reliable, repeatable crankshaft indexing for timing, injector service, or overhead work, this solid-steel Moker barring tool is built to replace the OEM part without sacrificing durability or fitment.
