Charlotte Mobile Diesel sets up heavy equipment repair in the field, alongside mobile diesel truck repair, diagnostics, fleet PM and roadside service for crews working the Charlotte region.
Grading crews across Union, Cabarrus and York counties work in Piedmont red clay that turns to paste after a storm and bakes hard in July. Machines that stop in that mud usually can't be loaded onto a lowboy without making the problem worse, which is why field repair is standard practice.
Machines covered
- Hydraulic excavators and mini excavators
- Wheel loaders and backhoe loaders
- Crawler dozers
- Skid steers and compact track loaders
- Articulated dump trucks
- Job-site generators, compressors and light towers
Hydraulic repairs
Hose fabrication
Blown hoses are the most common field call. Hose is cut and crimped on-site to SAE 100R2, R12 or R13 or ISO 18752 pressure classes, with JIC or ORFS fittings matched to the original.
Cylinders and leaks
Rod seal leaks, scored rods and loose glands. Some cylinders can be resealed in the field; others are pulled and sent out.
Pumps and pressure
Slow or weak hydraulics are checked with flow and pressure gauges against the machine's relief settings before parts are condemned.
Engine and electrical
Tier 4 Final machines carry the same DPF and DEF systems as on-road trucks, plus monitor-panel fault codes. Field techs bring dealer-level software for the common makes and handle starters, alternators, harness damage from brush and rock, and cooling problems from packed radiators.
Field repair process
- Lock out the machine, lower attachments and relieve hydraulic pressure.
- Identify the failed hose or component and measure fittings.
- Fabricate or replace, then bleed and top off hydraulic fluid.
- Cycle functions under load and check for leaks.
Hose, fluid and wear life
Hose life is mostly about routing — abrasion sleeves and proper clamps prevent most repeat failures. Use the hydraulic fluid the OEM specifies, change filters by the hour meter, and grease pins daily on machines working in clay and sand; dry pins are the fastest path to worn bushings and sloppy linkage.
