This listing is for a rebuilt injection pump for a John Deere 4020. We rebuild these in house at Badger Diesel using high quality parts and testing and calibrating everything on our Bosch test equipment. 

We typically have these pumps on the shelf ready to ship same or next day.

Our process is as follows: Pumps are torn down, cleaned up, and inspected for damage. All wear parts are replaced including the pilot tube, metering valve, delivery valve, delivery valve spring, transfer pump liner and blades, return connector, all gaskets, and governor cage. Then the pumps are reassembled to all factory specs then tested and recalibrated on our Bosch test equipment which means all of our pumps ran for at least an hour prior to leaving our shop.

All of our pumps get the upgraded EID weight cage installed as well as an upgraded pilot tube that does not wear out. 

If you're not familiar with an EID weight cage I'll explain: the old style governor weight cage was made of 2 pieces that were held together with a plastic "flex ring". The flex ring will get hard and break into pieces that look like coffee grounds inside your pumps. These pieces will plug your return line up causing the common stalling problem, hunting rpm, or lack of throttle problems. A lot of shops don't install these updates because it ensures you'll be back for another rebuild in the near future. One of the things I hear a lot about these from customers is that they say "I don't use the tractor much, so I don't want to spend the extra $100 for that upgrade, the old one lasted 20 years so it's fine without it. The answer to that is that todays fuel is not the same as it was for one and eats the plastic rings and for two, the sitting around is the worst thing for it because it just sits in the fuel and gets hard because it's not being flexed and kept pliable. I've see these flex rings fail within 2 years if they don't get used every day.

All of our pumps are rebuilt by either the owner Fred who's been doing this for 23 years or Jon who's been rebuilding pumps for 45 years, not a $15/hr trainee. Unlike our competitors flooding the market with cheap chinese parts and Krylon remans we refuse to sell low quality junk just to make a buck.

Since we are a full fuel injection shop we can stand behind what we sell and know what it is we are selling you, not like some of these other sellers that are just buying surplus parts and selling them then when there is a problem they tell you it's not their problem and don't even know how to help you.

Ask the other guys to show you pictures of their shop. These guys are doing this in their barn or garage in a dirty environment and don't even own a test bench to calibrate the pumps when they are done. Fuel injection work MUST be done in a clean environment due to tolerances in the 1-3 micron range. Calibration equipment is where the money is and if it wasn't required to do the job right we would rather have the money in our pocket.
