Your hydraulic temperature may not be as bad as it seems. I think JD gives and operating range temp of 150 to 180 degrees. A rule of thumb used by many is 100 degrees over ambient temp. Either way it will be uncomfortable to the touch, to say the least. Check it with a non-contact thermometer (heat ...

Going by memory the hoses to the cylinders on the (430C) 62 blade attached on the side of the base on the left cylinder and there were two plugged ports on the end of that cylinder when you looked at it when sitting in the seat. I think the hoses on the right cylinder base used all four ports as the...

That is where those number show up. Go to JDparts: Homepage and you can research further. Enter your model number; I picked a 350 crawler tractor based on your post title and looked at the winches; they show two the 3310 and the 3315. I did a search for T19800 for the 3310 and it didn't come up, tri...

To test the pressure (strength), I don't know if there is a test port on your machine or not but you can always get a Tee and a few fittings and add a test port into the pressure line coming from the pump to the valve (or into a hose going to a cylinder port) to check pressure. Get hydraulic fitting...

Drop the T suffix off the number and those are numbers for components of a 3315 winch, in looking at JDparts, for winches used on 350's. Is that what you were looking for?

If you lift your blade up, let the valve go to center (hold position) and shut the engine off. If the blade drops; it is most likely the problem is in the cylinders, as Lavoy said. A badly scored, or out of center, valve might do it but not as likely, from your description of the problem. I had a 43...

From info I found I would plan for the heavier weight Bruce posted. Some extend-a-hoes had to have front weights, bucket options change the weight, extra plumbing for other attachments, many things come into play on these. Looking at models each side of the 580K; a 580L series shows 13,200 to 15,750...

The PTO lever would be the little short lever just off the deck plates, left side just ahead of the seat base. Do you have a winch? That would be driven by the PTO. If you don't have a winch and you see just a cover plate at the rear, you don't have a PTO. I believe on some tractors, some of the int...

Actually the transmission dipstick may be right near the left front of the seat beside the PTO lever, not under the seat.

Under the seat I think your transmission should have a dipstick at the front left side. Not sure its been a while since i have been around a 350, but I looked at the parts manual and I think that is where you find it. You can get the manuals (printed or electronic) for your machine quick and easy fr...

There should be a number along with the TM on your manual. The 450B manual I found on line is TM1033; 332 pages. I found the idler wear spec under Miscellaneous Components, Tracks, Specifications. Page 38 of the Dresser undercarriage document a drawing of measuring an idler, same method shown in a p...

There was an inspection tool (JD268A) years ago that allowed for a quick check of track components. As far as I can find out those are no longer made. I believe John Deere may now have a full track inspection kit that covers all their machines now instead the old gauges (JD266, JD267, JD268A) for di...

Hi Will, My personal thought on the wear I see on the housing in your photo is that is the result of material passing between the housing and the sprocket over the years. It appears to be on the sprocket side of the housing, in line about center of the bottom roller, which is in line with where the ...

Yes this will screw into the end cap under the spring so you won't need a nut(s). My comment on the nuts was meant to cover the times where one needs nuts with the all thread; the grade of the nuts is important as well. You're headed in the right direction from what I see. It will be a big help to h...

Hi dtoots1, I would agree with you about a possible issue with all thread, but it looks like he got an Allen bolt (socket head bolt). If that is correct those are normally better than grade 5, the fastener shop should have been able to tell him that and it should work if it has the length of threads...
