I can only speak for my little 450c but I can barely get it up to temp in this cold weather. IMHO if you are in the red at all in the winter you will have trouble in the summer. My thermostat was about ten bucks from JD ,if it were my money I'd replace it. That's just my opinion and I'm pretty new t...

Upon doing more research I'm still a little confused and I called JD and while they did agree with me they did not instil much confidence. It appears if you have serial number less than 222447 stock was two springs T32048 & T20872 Serial numbers after that had a single spring of T106882 and a "tube"...

Thanks for the suggestions, I'll try and get a good look at those springs next time I'm out there. There is an inner spring on the 450'c as well. Looking on a few sites that sell after market parts most only show the outter spring, is the inner harder to get? Looking at the part numbers it appears t...

That's very close to a design that I was thinking about building.

Can you explain in a little more detail why the grapple will not open if the bucket is rolled back? It seems to be they should be independent functions.

Here is a picture of the old girl: http://i1205.photobucket.com/albums/bb423/psmith0803/sideview_1.jpg Some shots of the U/C for the discussion thread: http://i1205.photobucket.com/albums/bb423/psmith0803/idler2_1.jpg http://i1205.photobucket.com/albums/bb423/psmith0803/tracktopview_1.jpg http://i12...

Is 3/4" to 1" of extra sag loose enough for it to come off ?

I started some pictures over in the show and tell section:

Thank you again for all the help.

Thanks for the replies. I went out this morning and was able to get the track back on in about 45 mins. I picked up the front with the loader bucket and jacked up the back with a 8 ton bottle jack. I had the whole right side about 4 inches off the ground. I then was able to use a come a long hooked ...

I've trying to search and find some threads on getting a thrown track back on but i cannot find them. Does anyone know of any of the top of their heads? I was driving and hard a loud pop from the right side and the track was off. It didnt seem very loose to me but I had not actually ran the track me...

I think I'll just reuse these steel discs. I don't know where I would get them blasted, but maybe going over them with an emery pad will do the trick? Just a suggestion but in my little town the shops that do monuments and other types of stone work will do sand/media blasting. I have a little cabin...

I realize you're probably done but here is a good thread on the nose removal:

It's not a weep hole, at least I don't think. Let me try another way of putting it. From the back of the crawler going forward you have in order: Head>Gasket>Water pump back plate>Gasket>Water pump The hole is in the head, in the gasket and then stops. I realize some parts fit many machines but it s...

Update II: I may have another issue now. When I removed the water pump backing / upper radiator support plate I noticed beside the main water port there was a small 1/8" hole that also bleed out coolant. When I was cleaning up the water pump parts there is a hole in the gasket for this small hole bu...

Update: After still struggling to figure this out, I removed the radiator. My plan was to really clean the front of the engine and run it with the fan off and see if I could find where my water leak was coming from. I noticed an odd big flat washer on one of the water pump bolts during clean up. I r...

On my 450c it is on the right side of the transmission in the top of the cap that you remove to clean the screen. If you look thru the track you can see the bottom two bolts of the cap, it's about 5" or so in diameter. I had to take the top bolt out from under the machine with a wrench and then I co...

I just got done asking these same type of questions on a 450c, you might find some of your answers in here: http://www.jdcrawlers.com/messageboard/viewtopic.php?t=6712 Right now I have over sized washers holding mine solid. In the spring I plan on welding in either the old bushing or a new one I mac...
