Why Choose This Product?
Performing a valve adjustment or injector replacement on a Volvo D13 without the proper barring tool is an exercise in frustration. This tool engages the flywheel teeth through the bell housing inspection port, giving you the mechanical advantage needed to precisely rotate the engine to TDC. A $3,000+ dealer service becomes a DIY job.
Installation Notes
- Locate flywheel inspection port on bell housing (typically passenger side)
- Remove rubber inspection plug to access ring gear
- Engage tool teeth with flywheel ring gear
- Use 1/2″ breaker bar to rotate engine clockwise
- Never use an impact gun — hand rotation only for precise positioning
Frequently Asked Questions
Q: What services require this barring tool?
A: Valve lash adjustments, injector replacement, camshaft timing verification, DPF and EGR system service, and any procedure requiring precise engine rotation to TDC.
Q: Will this work on all Volvo D13 engines?
A: Yes. Fits all 2008-2020 Volvo D11/D13/D16 and Mack MP7/MP8/MP10. US10, US13, US14, and GHG17 variants use the same flywheel ring gear pitch.
Q: Can I use this with an impact gun?
A: NO. Always use hand tools for precise engine rotation. An impact gun provides no positional control and risks damaging flywheel ring gear teeth.
Q: Why does this cost less than the Volvo dealer tool?
A: The Volvo 88800014 is priced for dealer service departments. iFJF manufactures an equivalent tool from the same materials and specs without dealer markup.
Q: Does this work on 2021+ Volvo engines?
A: The 2021+ Volvo D13TC may use a different flywheel housing. This tool is confirmed for 2008-2020. Check your bell housing inspection port before ordering.
