What Does Big Pump Mean on This Cummins 4BT?
Big pump is a practical stock and workshop description used to separate this unit from a small-pump 4BT. It is not a universal Cummins engine code. The pump make, model number, mounting, linkage, governor arrangement and fuel-line positions must be compared with the original engine before the order is approved.Information Required for a Correct Engine Match
Cummins 4BT engines were produced in different ratings and equipment configurations. Even when two engines share the 4BT name, they may differ in the fuel pump, turbocharger, manifolds, sump, flywheel housing, front accessories, starter position and engine mounts. Please send LRD Pretoria the following:- Cummins engine serial number
- CPL number from the dataplate
- Injection-pump make and identification number
- Truck or machine make, model and year
- VIN, chassis or equipment serial number where available
- Clear photographs of the complete existing engine
- Close-up photographs of the pump, dataplate and turbo layout
- Gearbox, flywheel housing and clutch details
- Engine-mount and sump photographs

A qualified diesel technician should identify the original failure before fitting the replacement engine. The cooling system, oil cooler, fuel supply, turbo and intake plumbing, exhaust, engine mounts, clutch or torque converter, electrical system and gearbox alignment must all be inspected. Correct-grade oil, coolant, filters and required service parts should be installed during the fitment process. Existing overheating, lubrication or fuel-contamination faults can damage the replacement engine and may affect warranty coverage.Request a Cummins 4BT Big Pump Quote
