Re: re..jd440 ic....main clutch

If you have service manual SM 2023 the rod shows, but is not called out as such, on the first page of the reverser section. It runs close under the shifter housing of the reverser. I can't say on a 440IC, but on my 430 I could see and adjust it from the top. I do have a couple short wrenches I used ...

Re: 450C "Milky" engine oil

I would recommend buying only the proper O-ring seals for the engine (and installation lube), not trying to get them from a place with run of the mill stock O-rings on a shelf. You can drop the pan, pressurize the radiator and lay under it and watch for leaks. You may need to let it set a while befo...

Re: 1973 450B

Yes, they often get water in them from condensation (a common cause as dtoots1 posted) along with infiltration around gaskets and covers. Sometimes when oil is added it is contaminated. Buckets and drums setting outdoors will collect water, even if they are sealed, due to expansion and contraction. ...

Re: 420c Trans/reverser seal

Have you sent Lavoy a direct email (postmaster@jdcrawlers.com) or called him (701-361-1006) during central time zone business hours? I know he has posted before he has parts for them. He has also posted, in the past, he doesn't always catch things people mention in posts or get PMs, so he asked for ...

Re: 1965 straight JD crawler help

Does the hydraulic lift on the back of yours look similar to this one? You might have just the beam without the shanks(teeth). You should post a couple photos showing your complete machine

Re: 1965 straight JD crawler help

Yes, people put kits in them themselves. However I don't believe they have the wear limits and specs to set them up by, nor proper equipment to calibrate them with. Depending on how far you have to go, your pump may need a Bristol bit or two, not torx bits. Some succeed, some end up breaking somethi...

Re: 1965 straight JD crawler help

You have it identified correctly. Machine serial number tag breakdown using the 350 Introduction from the JD parts Catalog: SN = serial number T = Tractor 4 = JD350 F = Crawler Dozer 3 = Diesel D = (Transmission) Sliding Gear with Reverser Serial number: 010120 (This number falls in the 1965 build r...

Re: 1965 straight JD crawler help

Welcome to the board. If you would post the model and serial number of your crawler it will be easier to help you, saying straight 1965 JD crawler, it could be a couple different ones. You should contact Lavoy (postmaster@jdcrawlers.com). He owns this site and his business of selling parts and repai...

We can't see it to know anything beyond what you post, 2k may be a good deal, maybe not. Have you verified the year by the serial number? Undercarriage is fine based on what? Looks good to you (We don't know how much undercarriage experience you have to make an eyeball judgement, not saying your jud...

Re: 1972 450B

I interpret what you are saying is the bare machine, blade off the ground, will move and turn on flat ground. It could be many things, real diagnosis is required to pin point the issue. Some things are: out of adjustment or bad engine clutch, linkages for reverser out of adjustment, low pressure in ...

Re: 450e cab

Please define cab, it can mean different things to different people. Are you talking a fully enclosed hard panel/windows EROPS cab, or a ROPS with screens as you were indicating interest in, in a previous post? The 450E is a flat deck operator's platform, the 450C is not. I may be wrong, but I have ...

Re: Seeking advice on replacing high pressure hydraulic line in a 450B

They use "Rotella" in many oil/fluid names. He is correct Shell Rotella HD Tractor Fluid meets J20C, I am assuming he is using the Tractor Fluid. When I searched Shell Rotella HD, the Tractor Fluid came up, not engine oil. https://shell-livedocs.com/data/published/en-US/7075ff70-f224-40e3-981d-ff35a...
