Classic inline pumps remain the dependable core of Zimbabwe’s transport fleets, agricultural tractors, and industrial generators. These mechanical assemblies require precise synchronization to ensure steady engine governor operation under varying loads. Revcounts Diesel & Engineering preserves their life by ensuring exact fuel delivery across these heavy-duty systems.
Our technicians utilize heavy-duty Bosch test benches to systematically adjust timing for inline pumps from brands like Bosch and Denso. We rebuild components including plungers, barrels, and delivery valves to restore peak operating standards. Every calibration is performed strictly in-house, eliminating the need for external assistance while maximizing equipment longevity.

Pressure & Seat Testing
We perform deep wear profiling against OEM tolerances to identify surface imperfections on the plunger. High-precision lapping then restores the internal geometry required for consistent stroke volume and stable high-pressure delivery.
We inspect barrel bores for wear or scoring to ensure a perfect seal with the plunger. Precision boring and honing restore internal dimensions, ensuring accurate fuel volume per stroke across all cylinder lines.
Each delivery valve is tested against factory pressure limits to ensure it seats correctly during the injection cycle. This prevents backflow and ensures that fuel reaches each cylinder at the precise moment required for optimal power.
