Service Overview

The heartbeat

of your engine.

Rotary and inline diesel injection pumps are the heartbeat of heavy-duty engines, and when they drift out of calibration, you feel it in fuel bills, power loss, and hard starts. Our Bosch 4 kW Diesel Test Bench Machine is purpose-built for these pumps, delivering volume calibration, governor adjustment, and timing verification against Bosch factory output curves. From tractor pumps to bus engine pumps, we restore factory-spec performance every time.

Warning Signs

Your pump is

calling for help.

A misaligned injection pump doesn’t just hurt performance; it can cause long-term engine damage. Catch these signs early before a minor calibration turns into a major overhaul.

The engine loses power under load, especially noticeable uphill or with heavy cargo.

Fuel consumption has increased noticeably; you're burning more diesel per kilometer.

Hard starting in the morning or after the engine has cooled down completely.

Excessive white or black smoke from the exhaust during startup or acceleration.

Unusual knocking or rattling sound from the engine, especially at idle.

The engine takes longer to respond to throttle input, delayed acceleration.

FACTORY OUTPUT CURVES

Calibrated to Bosch standards.
