130cc DB2 Injection Pump Rebuild

  • $1,250.00


The 130cc db2 is the first step in our performer series pumps, and offers all the same features of a stock pump, with the heavy duty upgrades that our performer series get to handle more than double stock fuel displacement. Built with our 4500 rpm governor spring and custom delivery valve, this stock plunger sized db2 puts out over 150cc at peak fueling, and 130cc at 2800 rpm, while still retaining a light load advance for better fuel economy, cold high idle, cold advance and designed around stock lift pump pressures (5 psi +/- 2.5). This pump is recommended to be built with a 92+ housing with a torque screw for fine fueling adjustment but is not required. Pumps built without a torque screw are non adjustable from max fuel setting, pumps built with a 92+ housing will have several fuel settings for different torque screw heights, without any loss in performance.

All CDD built DB2 injection pumps are built to and exceed oem specification. All pumps are built with a new advance piston, metering valve, transfer pump liner, blade set and delivery valve. A common issues with the design of the DB series rotary pump is rapid wear of the advance piston bore due to the hardened piston sliding in the aluminum bore quickly eroding the critical tolerance due to lack of lubricity of modern diesel fuel. Most cheaper rebuilds ream out this bore and fit a larger piston, but this is just a temporary fix and soon the hydraulic advance will be out of spec, resulting in a lack of power, high egts and a smokey exhaust. Our solution is to mill out this bore and install a ceramic sleeve. This ceramic sleeve allows us to create a better fit than with the original design, and shows no wear after over 100k miles, extending the lifespan of the pump, and maintaining the same out of box performance many years down the road.

-If sending a core afterwards, a $200 core charge will be refunded after the core has been received and inspected.
