Is there any chance this is just a really weak motor? Doesn't have the power to turn both sides? I guess i'm trying to think outside the box here.

I think the 450b will be more like the 450c than the 450's. Are you looking for something specific ?

I'd guess it's a straight with C stickers.

Mine is the exact same way even after having the injection pump rebuilt. Been that way the entire time I've owned it. I know I need to rebuild the motor as it has low oil pressure (but enough) I assume it's a lack of compression causing the issue but I certainly do not know for sure. The people on t...

As stated that will probably work in the hydraulic system but you should not run that in the HLR. You will have to keep 2 oils around, which no one likes to do that is why most of us run a hydraulic/transmission oil in everything. I purchase mine in bulk 55 gallon barrels from Petrochoice and save a...

If it's like my 450c the oil pressure sending unit is right rear of engine. It should have a filter in the tank yes, you'll have to open the top of the tank to service it. Mine had fallen off and was in the bottom of the tank.

Probably so, if it's an original style adjuster, remember you do not need to take the bolt all the way out just loosen it till grease starts to flow out the hole. Then you are less likely to loose the BB.

I highly recommend "thepumpguysc" from the heavy equipment forums. You can send him a message with what your have and he's very responsive, I had my pump back in less than 10 days total.

It's wide track with full rops and looks like a 6 way blade all in one package:

Always nice when a plan comes together!

Well I got the new idler, it's not made the same as the old one it's basically flat inside more like a wheel than the original. The front idler shields will not fit correctly. There are two options, I can install without or I can try and flatten them out and reshape then. I'm wonder because the idle...

You can't really weld it shut, you'd never be able to collapse the adjuster when you need to work on the track or put a thrown track back on. There has to be something wrong or stuck in the hole. I'd clean it out really well carb cleaner/compressed air and find out what's preventing it from sealing ...

You could have your correct OEM pump rebuilt for less, that is what I would do. Those pumps are fairly specific and I think swapping part numbers would be a bad idea unless JD tells you it's an obsolete part number that has been replaced with the other number.

Anyone see the opener of gold rush one of the crews had a little JD dozer pushing snow and "saving the day"....lol

For those reading along a standard 450c master pin will not work with the berco tracks, it's too small. I think it's 1.250 and I need 1.375 =(
