Re: Trans cooler.

Machinery can be the absolute best water condensers. I have seen machines collect gallons of water and them not be setting for very long in the process. You being in central Texas where the humidity is nearly always high doesn't help in that respect. We have the same issue here in Missouri as we dra...

Re: 350 Brake Band Adjustment

Well your spring isn't that strong. The bolt should turn relatively free until it begins to bring the band in contact with the drum. That is when you should notice it getting snug as the book says. Usually you can tell when it is getting tight. One thing to look for is the detent shoulder at the top...

Re: Diesel fuel additives

Your best defense is clean fuel. Keep it clean to begin with and that alone will take care of most issues. However... this time of year and given your location a good anti jell additive is a good thing to have. I've used a variety of different ones but usually stick with "Howes Diesel Treat" or "Hot...

Re: 350 Brake Band Adjustment

If you're sure you have the adjustments correct and it is good and dry down inside the steering clutch housings, I would run it some. Put a few hours on it and see if it works its way out. I've found over the years that new parts need to be "Run In" so that they will function properly. Run it and th...

Re: Jd450 straight oil in bell housing. How to find it

Okay so my question is, where are you adding oil to replace what has leaked. Your leak can be either from the transmission or the machines hydraulic system. The two systems are not connected so if you're losing oil then where are you adding it back? Your drill idea should have worked even at low RPM...

Re: Thinking About Buying a 1967 JD 450 Dozer

Dude... it's your money but that thing is junk! Anything beyond scrap iron price would be too much. Sorry to be so blunt but I would keep your money and go look for a better machine.

Re: 450B Steering Issues…

First of all welcome to Missouri!! I'm north and a bit east of you near Jeff City. And you're right about the rain. We can go from flood to drought inside of a week. Assuming you have a tech manual I would refer to it for all of the linkage components. If you don't have a manual then you need to get...

Are you sure this is a 350? Because I have never seen or heard of one with a 4 cylinder engine.

Re: 350B WINCH instal with no pto lever

Just and FYI... I need to add that if you have a reverser then your PTO will not function if the reverser is in neutral. The 350 PTO is driven by transmission gearing and it is powered by the reverser. It may try to turn a little bit just from the friction that is inherent in the drive line. But put...

Re: 350B WINCH instal with no pto lever

Yes... if the lever is there then all you need is the shaft assembly. On some models you could install the shaft assembly even if there was no lever. The difference is you can't turn them off since there is no lever with a slider inside the transmission. In other words the shaft will spin all the ti...

Re: Jd 550 dozer

Also a good tech manual is a great place to start. If you don't have one then I highly suggest you get one. You will need it for other things you will undoubtedly come across.

So what is your starter doing? You may not need to replace the whole thing. Tell what it's doing and we will go from there.

Re: Jd 450 clutch adjustment problem

So it has been forever plus three days since I last worked on one of these 450 clutch / HLR's. But as I recall there are two things that could be your issue. The first is the pressure plate for the engine clutch. They should be set with a gauge?? I think!! Like I said it has been well over twenty fi...

Re: 350c dozer dealer manual hours

They will weigh roughly 400 to 500 pounds as a unit. What I mean by that is when you pull it, it will come out with the radiator, hydraulic pump and muffler still on it and you can leave the oil and coolant in them as well. Strip some of that off and you can get them down to 400 pretty easily.
