Preventive Maintenance
Scheduled PM, DOT, annual and warranty inspections. Performed at your facility.
Overview
Preventive maintenance only works when it actually happens. Traveling Wrenches brings your PM program to the yard, the lot, or the transit facility, so units stay on schedule without ever leaving revenue service longer than they have to.
Why Mobile Matters
Every trip to a shop costs deadhead miles, a pulled driver, and a unit out of rotation. Mobile PM keeps inspections current and compliance intact without breaking your dispatch.

What's Covered
- PM ServicesInterval-based inspections and service executed at your yard on your schedule. Fluids, filters, brakes and multi-point checks documented per unit. PM compliance stays current without a single shop trip.
- DOT InspectionsFull DOT inspections performed on-site by a qualified technician, with the documentation your compliance file needs. Units stay in rotation while the inspection happens where they sit.
- Annual / Federal InspectionsAnnual and federal inspections completed at your facility, with flagged items quoted and repaired in the same visit where possible. No scheduling around a shop's calendar.
- Warranty InspectionsInspections performed to OEM warranty procedure with documentation to match. We follow the applicable OEM procedures and understand the documentation needed to support warranty review.
