Semi truck repair
Tractors and trailers. Tell us the unit, the symptoms and where it's parked.
Questions about symptoms
The truck won't start, or it starts hard.
No-start and hard-start problems can be fuel, electrical, air or a mechanical issue. Note whether it cranks, any warning lights, the last fault codes if you have them, and whether it died while running or sat and then would not start.
It won't build air, or I can hear a leak.
Write down whether the compressor runs, how high the pressure gets, and where you hear or feel a leak if you can. That helps us ask the right questions about brakes and air.
A warning light is on and the truck is derated or down.
If you can, jot down the fault codes and when the light came on. Send those with the unit number, location and whether the truck can still move.
What to send us
- Make, model and year if you know them
- Serial, VIN or unit number
- Where the equipment is, and whether it can move
- What it is doing, and any fault codes
- Photos, emailed to office@omnicranediesel.com after you send the request
