24-Hour Rush Repair
Find the fault first · Fontana, CA
Heavy Equipment Diagnostics
The costliest repair is a repair that was never needed. Our diagnostic work exists to prevent exactly that: a structured teardown and inspection of the failed system, documented with photos and video, so the quote you approve covers the failure you actually have — not one somebody guessed at over the phone.
Find the fault first · Fontana, CA
What a proper diagnostic visit involves
We begin with the symptoms exactly as the operator experienced them — the noise, the leak, the loss of power, and when it happens versus when it doesn't. Then the machine or component comes apart far enough for the failure to be seen directly: wear patterns, scored surfaces, contamination, cracked housings and damaged gear teeth.
You receive the findings exactly as we found them: photos and video, plus a plain-language explanation of what failed, why it likely failed, and the repair options open to you — from a targeted repair through to a full rebuild — each with its own written quote.
Diagnostics for heavy equipment · Fontana, CASymptoms we track down week after week
Hydraulic drift and weak lifting power, overheating, grinding or whining noises from gearboxes and final drives, power loss under load, diesels that start hard or not at all, slipping transmissions, metal showing up in the oil, and the puzzling intermittent fault that only appears under load. Intermittent faults are precisely where documented, methodical diagnosis earns its keep.
Diagnostics form part of our standard process, and both the inspection and the quote are free. Regular hours are Monday to Friday, 6 AM–5 PM, and the rush line operates 24 hours a day, every day of the year.
- Isolating engine and drivetrain faults
- Checking hydraulic pressure and contamination
- Analysing gearbox and final-drive failures
- Starting, charging and electrical faults
- Machine evaluation before purchase or sale
How a repair moves through our shop — eight steps
From your first phone call through to a tested machine or component heading back out, this is the route every job follows.
Inspection
The unit comes apart so the full extent of the failure can be assessed.
Photos & video
We record what we find on camera, so the conversation about repairs starts from evidence.
Repair quote
You get a written price covering the work we recommend, before anything begins.
Approval
Together we settle the scope, the timeline pressure and the most sensible way ahead.
Manufacturing
Whatever the job needs gets machined, welded, rebuilt or reverse engineered in-house.
Testing
Operation and workmanship are both checked before anything is released.
Shipment
The finished component or machine goes back out and back to work.
Frequently asked questions
Does the diagnosis cost anything?
Both the inspection and the repair quote are free, and the scope is approved by you before any billable repair work goes ahead.
What do I receive from the inspection?
Photos and video showing the failure, a plain explanation of our findings, and your options in writing with quotes attached.
Can you diagnose a machine that fails only intermittently?
Yes — just bring us the pattern: when it occurs, under what load, and whether the machine is hot or cold. Intermittent faults are a specialty of our diagnosis work, never a nuisance.
