    Break in for a JD 4440

    Zinc dialkyldithiophosphate (ZDDP) in gear head terms is an additive that was formerly used in engine oil's to help minimize wear especially at the interface of a hydraulic flat tappet lifter, and camshaft. It was significantly lowered by EPA due to lowering emmissions. If you want to go...

    4430 air in coolant

    already mentioned to use thermostats with a "jiggle valve" or run Mr. Gasket 4367 thermostat (this is the correct P/N for my 4230) and is a great copy of the old Robert Shaw thermostat's that I'm confident were OE for Deere in the 60's and 70's (and possibly 80's) They are provisioned too...

    Could this be a John Deere dozer

    I've got an old JD 440IC in one of the old barn's that hasn't run in 20 years, last year I pulled the plugs and in the inside of the cylinders looked great so I sprayed a bit of diesel/atf mix in them). I'm tempted to tinker with it to get it running again, but I'm not sure if it's really...

    Doing an in-frame/rebuild on a 1973 4230

    I got all the pistons out of the engine yesterday. Hoping to pull the liners today but was told not to do so without a tool. I was hoping to just pop them out with a slide hammer. When it comes to ordering rebuild kits, I went to F-M's industrial website, downloaded the catalog, found the...

    Doing an in-frame/rebuild on a 1973 4230

    did some more work on the tractor today...I got everything out of the way and prepped to pull the pistons and liners tomorrow. I spent an hour chatting with the tractor mechanic that did the last in-frame overhaul. I asked him questions, he asked me questions and seems to give advice based...

    Doing an in-frame/rebuild on a 1973 4230

    That's one way of looking at it....but after seeing how rusty the water in the block is, I'm not optimistic that the liner sealing surfaces will be good. https://imgur.com/a/DN7cF7F This post was edited by shanker on 10/04/2022 at 01:42 pm.

    Doing an in-frame/rebuild on a 1973 4230

    That's why I need to figure out the engine spec's even with the missing ESN plate. Ag Kits lists the Reliance Hyper-Formance kit, but I need to verify if it's a compatible option. I'm going off of it being a 6.404-D This post was edited by shanker on 10/04/2022 at 01:45 pm.

    Doing an in-frame/rebuild on a 1973 4230

    Tractor is a 4230, sycro-range gear box, 158 loader, with 4 post roll guard station that's been owned by us for 30 years or so. I'm essentially doing an in-frame on it due to a liner seal failure from having just tap water in the cooling system that turned to rust water. It's last in-frame...
