Preserve the legacy of heavy equipment with the ultimate 12-port mechanical fuel delivery measuring machine. The 12PSB series is engineered specifically for workshops servicing older agricultural, marine, and construction fleets that rely strictly on purely mechanical fuel systems.
Operating as a highly dependable traditional inline diesel pump adjusting rig, it utilizes variable frequency drive technology to smoothly simulate engine RPMs. Mechanics can accurately observe fuel quantities across a dozen glass graduates, ensuring perfect synchronization and phasing for large-displacement engines.
Furthermore, this robust framework excels as a conventional rotary distributor checking equipment. Technicians can seamlessly perform governor testing, advance angle verification, and internal pressure measurements, bringing classic diesel engines back to optimal performance.
