Bosch Diesel Injection Services
in Montevideo, MN
Bosch diesel fuel systems demand precision, especially when modern common rail components operate under extremely high pressure and tight internal tolerances. At DK Diesel Injection Services, we provide Bosch diesel injection repair in Montevideo, MN, for agricultural equipment, commercial trucks, diesel pickups, and other hard-working applications throughout the Minnesota River Valley. Since 1973, our team has specialized in diesel fuel injection service, testing, rebuilding, calibration, and replacement. As a factory-authorized Bosch Diesel Service Center and Association of Diesel Specialists member, we use specialized equipment, genuine Bosch components, and established repair procedures to deliver dependable results.
Factory-Authorized
Bosch Fuel Injection Service
Bosch fuel systems are found in everything from older mechanically injected engines to modern high-pressure common rail applications. These systems require specialized testing because small changes in flow, leakage, response time, or spray quality can affect starting, power, emissions, fuel economy, and engine durability.
Our Bosch fuel injection service goes beyond basic troubleshooting. We use dedicated test equipment and manufacturer-based procedures to evaluate pumps and injectors accurately before recommending repair, rebuilding, or replacement.
Bosch Common Rail Injector Testing and Rebuilding
Common rail injectors must meter extremely small amounts of fuel at precise times and pressures. Contaminated fuel, carbon buildup, internal wear, or electrical faults can lead to rough idle, smoke, hard starting, poor fuel economy, and loss of power.
Our Bosch injector testing service includes diagnostic evaluation, ultrasonic cleaning, flow and return testing, and calibration. When rebuilding is appropriate, worn internal components can be replaced with genuine Bosch parts before the injector is tested again against required performance specifications.
Bosch Diesel Pump Repair
High-pressure fuel pumps are at the heart of many Bosch systems, and internal failure can affect the entire fuel circuit. Problems with CP-series, VE, VP, and other supported pumps may cause low rail pressure, no-start conditions, reduced power, or contamination downstream.
Our Bosch diesel pump repair process includes bench diagnostics, cleaning, seal replacement, rebuilding, and calibration when the component is serviceable. If faster turnaround makes more sense, we can also discuss an exchange pump from our large Midwest inventory.

Exchange Pumps and Injectors for Faster Turnaround
Downtime matters during planting, harvest, hauling, and other time-sensitive work. Waiting for a custom rebuild can become expensive when a combine, tractor, semi, or work truck needs to return to service quickly.
DK Diesel Injection Services has access to more than 1,000 exchange pumps and 3,000 injectors across our exchange inventory. That availability often gives customers the option to install a shelf-ready, pre-calibrated component instead of waiting for their original unit to be rebuilt.
Fuel System Contamination Cleanup
Certain high-pressure pump failures can spread metal debris throughout the common rail system. Replacing only the failed pump without addressing contaminated rails, injectors, lines, or the tank can put replacement parts at risk.
We provide fuel-system contamination evaluation and cleanup for qualifying Bosch applications. Depending on the failure, service may include flushing, tank cleaning, line inspection, component replacement, and verification that the system is ready for clean fuel and new or rebuilt parts.
Heavy Equipment Service
in Oversized Indoor Bays
Our Montevideo facility at 7030 County Road 15 SW is built to handle more than pickup trucks. Oversized drive-in bays allow us to bring tractors, combines, agricultural machinery, semi-trucks, and other large equipment indoors for diagnostic work, component removal, and installation.
That capability is especially valuable during Minnesota winters, when outdoor repair work can be difficult and time-consuming. Farmers and commercial operators can bring the complete machine to us instead of removing fuel-system components themselves.
Our Bosch Diesel
Service Process
We follow a structured process because accurate diagnosis should come before expensive replacement. Testing first can help determine whether a component needs rebuilding, cleaning, recalibration, or complete replacement.
Our process can include:
- Visual inspection for wear, contamination, or electrical faults
- Ultrasonic cleaning and careful component preparation
- Bosch-specific bench testing
- Fuel delivery and return-flow analysis
- Spray-pattern and response evaluation
- Genuine Bosch replacement components when rebuilding
- Precision calibration and leak testing
- Installation for drive-in equipment
- Local pickup or regional shipping for off-equipment components
This repair-first approach can help preserve serviceable parts and avoid unnecessary replacement. When a faster exchange option is more practical, we can explain that path clearly as well.
Ag and Commercial Bosch Applications
Bosch fuel systems are used across a wide range of diesel equipment, so our work extends well beyond one vehicle type. We support applications involving agricultural machinery, commercial trucks, pickups, fleets, and heavy equipment.
Our customers commonly bring us Bosch-equipped systems used in John Deere, Cummins, Case IH, Caterpillar, Duramax, and other applications. Compatibility and repair options depend on the specific pump, injector, engine, and part number, so we confirm the component before recommending service.
More Than 50 Years
Serving the Region
DK Diesel Injection Services has served diesel operators since 1973, giving us more than five decades of specialized experience. Under the hands-on leadership of owner Kyle Dillman, we continue to focus on diesel injection as a core specialty rather than treating it as a minor add-on service.
We serve customers throughout Montevideo, Watson, Milan, Granite Falls, Dawson, Madison, Clara City, Chippewa County, Lac qui Parle County, Yellow Medicine County, Swift County, and the broader Minnesota River Valley. Regional customers across western Minnesota, eastern South Dakota, and northern Iowa can also use our exchange and shipping programs.
Warranty Protection
on Bosch Service
We back qualifying rebuilt, serviced, and exchanged fuel injection components with a strong warranty program. Exact coverage depends on the component and service performed, so we explain the applicable warranty before the repair or exchange is completed.
That support reflects our emphasis on accurate testing, proper calibration, quality parts, and workmanship. We want customers to understand both the repair and the protection that comes with it.
Put Your Bosch Fuel System
in Specialized Hands
Bosch fuel injection systems reward precision and punish guesswork, especially when high-pressure pumps and common rail injectors are involved. At DK Diesel Injection Services, we combine factory-authorized Bosch capability, more than 50 years of diesel experience, genuine replacement components, oversized drive-in bays, and one of the Midwest’s largest exchange inventories. So whether you need Bosch common rail service, injector testing, pump repair, contamination cleanup, or a fast exchange unit, our team can help you choose the most practical path forward. Simply contact DK Diesel Injection Services today to schedule a service appointment or discuss your Bosch fuel-system needs.
