Frequently Asked Questions
What size compressor is required to break harmonic balancer bolts loose using this tool?
This tool is intended to work off no more than a nominal 90 psi, but given frictional losses in the airhose, you can safely set your compressor to 100 or 110 psi without doing damage. Harmonic balancer bolts may come in various sizes, so an answer is difficult - but I can tell you that I've loosened overtightened wheel nuts (probably run up to 100 lb-ft of torque), though only after boosting compressor output to 100 psi. As for SCFM, keep in mind that such tools are heavy users of compressed air, so continuous running will cause rapid cycling of the compressor, unless you have a commercial/industrial size unit.
What is the PSI on this Air Impact Wrench?
The maximum recommended PSI for use with this wrench is 90 psi.
