Did you know the HCNR-43681 exhaust valve seat insert fits industrial/construction machines, tractors, combines, sprayers and harvesters? TractorJoe does, which is why we strive to verify our parts, ensuring they fit your John Deere properly. This exhaust valve seat insert is not only made for the John Deere 646B industrial/construction machine, but also fits the John Deere 500, 500B, 600, 644, 500C, 510, 646, 690B, 690, 690A, 644A, 3020, 4000, 4020, 4040, 4050, 4230, 4240, 4520, 4620, 7020, 4235, 6620, 6600, 7700, 6602, 4930, 5200, and 5400.
Whether you have the 646B, the 500, or something else, John Deere exhaust valve seat inserts are expensive and thats why we sell exhaust valve seat inserts direct at significantly lower prices than your John Deere dealer. You can save up to 70% with TractorJoe.
Price is just one part of the equation though- quality matters too. We don't want you replacing your exhaust valve seat insert more than you need to, which is why we back our parts with an industry leading warranty. Even if your 646B, 500, or 500B is not your main piece of equipment, TractorJoe knows that having it up and running is always important.
It doesn't matter if you're installing our exhaust valve seat insert in your John Deere industrial/construction machine, John Deere tractor, or something else, we'll be here for you. Our staff knows a lot about John Deere equipment, and our Q and A community is there for any other questions you may have.
