Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
Engine Selected John Deere 4045 and 4045T applications using RE48786 / RE44508
Equipment Certain Deere 110, 120 and 230LC applications with the matching engine/fuel system

Product Overview

Fuel injectors with poor spray pattern or opening pressure can create rough running, smoke, hard starting, diesel knock and uneven cylinder temperatures. A matched set can be useful when servicing an engine with multiple high-hour or failed injectors.

The original listing references machines such as 110, 120 and 230LC, but injector fitment is controlled more reliably by engine serial/build and injector number. The John Deere 4045 family has used multiple fuel systems, so RE48786/RE44508 should be confirmed before ordering.

Key Features & Performance

  • Six-piece mechanical injector set
  • Cross references RE48786 and RE44508
  • For selected John Deere 4045/4045T industrial applications
  • Matched-set replacement helps keep cylinder fueling consistent

Specifications & Reference Numbers

  • Quantity: 6 injectors
  • References: RE48786, RE44508
  • Part type: Diesel fuel injector set

Before You Order

Verify injector number and engine serial/build. Do not order solely from the 4045 engine designation because later 4045 engines use different injection technology.
