Electrics, lighting and trailer couplings lead the list for the John Deere 5090R. Add the rest and you get more than 450 parts for the 5R/5RN series.
This page gathers more than 450 replacement parts for the John Deere 5090R, from GRANIT, HELLA, Sauermann, MAHLE, GRAMMER and others. They cover the jobs that tend to come round on this tractor: belts, seals, starting and charging, lights and the cab.
You will find single multi-rib belts and complete belt kits for the 5090R. The routing on a tractor with air conditioning differs from one without, so check for an aircon compressor on the front of the engine before you choose. A kit without air conditioning will not fit a tractor that has it, and the other way round.
Tip: photograph the belt path before taking the old belt off. It is easy to miss a loop around the tensioner or an idler, and a multi-rib belt that is routed wrongly will walk off the pulley within minutes.
Both standard starter motors and gear reduction starters are available, together with alternators and a range of sensors. If the engine cranks slowly, look at the battery terminals and the heavy cables before blaming the starter. Corrosion at a terminal is a common problem and a quick one to fix.
Any O-ring disturbed during fuel system work should be replaced rather than reused, since a flattened ring is a likely source of air leaks.
Work lamps, including a spotlight version, and left or right headlights keep visibility up. In the cab there are GRAMMER tractor seats and gas struts. At the back there are automatic drawbars.
Lights are worth checking on their mounts as well as their bulbs. A lamp that vibrates on a loose bracket fails sooner, even an LED one. Tighten the bracket, make sure the plug is dry and firmly seated, and if you see condensation behind a headlight lens, the seal has gone and replacement is the lasting fix.
The type plate confirms you are working on a 5090R. For seals and sensors, the reference number on the old part leads you straight to the right item on this page.
The 5090R belongs to the 5R series along with the John Deere 5100R and the John Deere 5125R, which have pages of their own. To see every other model from the brand, visit John Deere parts.
