Description
When it’s time to replace those pencil-type injectors in your John Deere, you’ll need the proper seals to do the job right. This installation kit gives you everything needed to reinstall injectors AR89564, RE37503, or RE36939 without fuel leaks or comebacks. It’s one of those small parts that makes a big difference between a job done right and one you’ll be doing over.
What You’re Getting
- Precision-sized seal (0.074 inch) that fits injector bores perfectly
- Quality packing material designed for high-pressure diesel fuel systems
- Complete kit means no guessing about what gaskets you need
- Direct replacement components that match original John Deere specifications
Built for Real Farm Work
This kit works across a huge range of John Deere equipment – from mid-size tractors like the 2755 and 3140 all the way up to heavy-duty machines like the 7600. You’ll find these same injectors in combines, loader backhoes, excavators, and even cotton pickers. Basically, if it’s got a John Deere diesel engine from that era, there’s a good chance this kit applies.
Made to Last
These seals are built to handle the pressure and heat that comes with diesel fuel injection systems. The materials resist swelling from fuel contact and maintain their sealing properties even after thousands of injection cycles. That’s important when you’re talking about systems that fire hundreds of times per minute.
Installation Notes
Always clean the injector bore thoroughly before installing new seals – any dirt or old gasket material will cause leaks. The 0.074-inch seal fits snugly, so don’t force it. A light coat of clean diesel fuel on the seal makes installation easier and helps prevent tearing during assembly.
