3020 CB pump update

4020_guy · Jan 22, 2022

My 3020 CB pump is leaking like a sieve. The tractor starts and runs perfectly. The pump is the later one according to JD parts used on engine 132000 and up. Should I try to get it resealed or bite the bullet and go with the newer JBD pump? What about the injector lines? Only place JD parts? Just wondering. Thanks for now.......Ron

The CB can be repaired, but the seal kit is very costly, and that pump has areas that can still leak when done. The JDB pump/lines makes for a better running engine in my opinion, JDB has a better low speed idle response than the CB does. My 1970 4020 still has the CB on it, but I have a JDB and lines ready to replace the CB soon.

Thank-you for the reply. What JDB pump suits and are lines hard to obtain?......Ron from Canada {like Bruce}
