Description
Overview:
The Injection Pump Kohler 3R71C is a precision fuel delivery unit for small diesel engines used in construction and garden machinery. Built around a robust, precision‐machined metal body with hardened internal components, it meters and pressurises diesel so it can be injected at the correct time and quantity for efficient combustion. This helps engines start reliably, run smoothly, and maintain torque under load. Suitable for plant such as compact dumpers, mixers, generators, mowers, chippers, and small tractors that specify the Kohler 3R71C pump, it supports dependable day‐to‐day operation on site or in the workshop. The assembly is designed for durability and stable calibration, offering consistent performance when maintained to the engine manufacturer's schedule.
Key Features:
- Durable metal construction with wear‐resistant internals for long service life
- Accurate metering for clean combustion, stable idle, and good throttle response
- Designed for engines requiring the Kohler 3R71C specification, ensuring correct fit and function
- Supports reliable hot and cold starting when bled and timed correctly
- Corrosion‐resistant finishes suitable for harsh outdoor environments
- Stable delivery under load for steady power in demanding applications
- Compact form factor to suit tight engine bays common in plant and turf equipment
- Replacement-friendly design; install following OEM timing and bleed procedures to minimise downtime
- Compatible with standard diesel fuels meeting EN 590; supports proper filtration practices
- Helps maintain fuel efficiency and reduce smoke when paired with clean injectors and filters
Typical Applications:
Used on diesel‐powered construction and grounds care machines that specify a Kohler 3R71C pump, including compact generators, light compaction equipment, site mixers, turf equipment, utility vehicles, and small agricultural implements. Ideal for restoring correct fuel delivery in engines with poor starting, uneven running, low power, or excessive smoke due to worn or malfunctioning pumps.
Also known as:
Diesel injector pump, high‐pressure fuel pump (diesel), fuel metering pump, diesel distribution pump, in‐line/plunger‐type injection pump (where applicable), diesel fuel delivery pump, injection unit, fuel dosing pump for diesel engines.
