Mobile Diesel Mechanic

Diesel Truck Giving You Trouble? Get Caveman on the Job.

Truck down with a load still to deliver?

Caveman Towing & Repair provides 24/7 mobile diesel repair throughout Southern Oregon and Northern California. Our service trucks bring technicians to commercial properties for roadside breakdowns and disabled vehicles.

Our mobile crews regularly handle regen, coolant leaks, air leaks, and hub seals. We assess the fault on-site and perform repairs we can complete there, saving you the tow when we can resolve the problem on site.

When Your Diesel Isn’t Running Right

Diesel problems often show warning signs before a truck stops running. Changes in power or engine temperature can indicate problems that deserve attention before the next long haul. Our mobile diesel technicians investigate performance concerns and determine which repairs we can handle on-site. Let us know about any of the following issues when you call:

Hard starting

Loss of power

Poor acceleration

Oil or coolant leaks

Overheating

Turbo problems

Unusual exhaust or smoke

Rough or inconsistent running

Fuel-system problems

Warning lights or fault codes

Engine performance that has noticeably changed

Regen Trouble Holding Up the Run?

Regens are one of the biggest sources of Caveman’s mobile repair calls. If your truck won’t complete a regeneration or has lost power with an aftertreatment warning, we can assess the problem on-site.

The warning message and any previous regen attempts give the technician a useful starting point. Our crew examines the issue before proceeding; a regeneration won’t correct every fault behind an emissions warning.

For a driver away from the fleet’s regular shop, mobile assistance can help address the interruption before committing to a tow.

Coolant Leak Repair

A truck losing coolant won’t get far if you keep topping it off. Our mobile technicians trace the leak and determine what repairs we can complete on-site.

The leak source determines the job. We address roadside coolant leaks and explain when the damage calls for shop equipment or further repair. You get an assessment of the actual fault instead of sending the truck straight to a repair facility without knowing whether mobile service can resolve it.

Air Leaks in Trucks & Trailers

An air leak can keep a truck parked even when the engine runs normally. Caveman provides mobile air-leak repair for commercial trucks and trailers.

Our technician locates the leak and inspects the affected parts before repairing it. Whether the problem is in the tractor or trailer matters, especially when the driver is hauling a loaded combination.

Fixing the leak where the truck stopped can save the hassle of separating the equipment and arranging transport to a shop.

Hub Seal Repairs

Oil around a wheel end is a reason to investigate before continuing the route. Hub seal work is part of Caveman’s mobile diesel service, giving commercial operators a repair option on-site.

Our technician inspects the affected wheel end to determine the extent of the work. Existing damage and access determine whether we can complete the repair there. If the problem extends beyond a seal repair, we’ll discuss the next step before the truck returns to service.

What Can Be Repaired Where You’re Parked?

A roadside repair depends on the fault and whether we can work safely. A truck in a freight yard offers different access from one on a narrow shoulder. Our technician considers both before beginning.

Caveman generally moves major mechanical work to a repair facility. Towing is also an option when a roadside repair is expected to take more than an hour or two. Our heavy wreckers can transport the truck to your designated shop, so an unsuccessful repair visit doesn’t leave you searching for another provider.

Commercial trucks account for most of our work. We’ve served Southern Oregon since 1972, with long-term employees who know how much a disabled vehicle can hold up. We take pride in clean service trucks and treating the driver waiting for help with respect.
