Hey Guys,I am looking at a JD 450C dozer. Here is the problem with it.It is a power shift model. It started with the steering getting weak. Then it got to where it wouldn't pull in higher gears. Now it will barely move and the hydraulics are very slow. The owner said he did some checking and some people said it might be a charge pump. I am not sure.
I have worked with tractors and trucks but not on tracked equipment. What would I be looking to fix it if I got it? It has about 500 hrs on an overhaul and 60% on the UC and a 6 way blade. I've had lots of experience running them, but I never could figure out their transmission. It's a lot different than Cat.That hydraulic system is separate from the transmission though, sounds like more than one problem.I'd say it's got worn steering clutches in the best case scenario causing the lack of steering and then not pulling in the higher gears.If the tranny has some bad clutch plates, that would cause it to slip in the higher gears and would be a lot more time and money to fix.I'd say you need to check trans pressures first to see if they're OK. I've got the service manual on it if I can scan something for you or look it up, I'd be glad to. Like I say, I've ran several but never worked on the transmissions or the steering clutches.
I'm just thinking out loud.The lack of steering could be caused by the brakes being out of adjustment too, but can't tell from the info provided.Let me know if you need something out of the service manual. Click to expand. Like the adult undergarment, it depends. If you can get a usable JD450 for $10K, that is a good price. Would not take much work to amortize the purchase/repair. At $40/hr that works out to 250 hours run time, or a little over 6 weeks.However if there is more things wrong to repair before it is a working machine that changes the economics of it. Or if the repair parts are unobtanium that changes things as well.BTW in my experience, no used small dozer in the $10-$15K range is without problems.
If they are mechanically perfect they go for a bit more. If it is a John Deere 450C it is not a powershift.
It has a four speed gear type transmission which has a shifting lever for selecting one through 4. A second shift lever is for high foreword, low foreword, low reverse and high reverse. There is a conventional disk type clutch in the system which is activated by the clutch pedal with the operator's foot. The high/low/foreword/reverse shuttle is a hydraulic type clutch separate from the standard clutch.To start it sounds like the steering clutches may need to be adjusted.

(simple procedure)The clutch may also need adjusting. (simple procedure but harder than the steering clutches) Takes a pressure gauge to to the transmission clutch. Best to get a tech manual which will give the details to do both.If you have to go inside of the transmission and change the clutch good luck. These little bit-es are a real stinking nightmare to work on. I made a mistake it is a 450BThanks for the information. I might write the guy. I am wondering if the pump is getting weak too since the blade is slow too.
I imagine the pump isn't the easiest thing to change. I have found them for the 500 dollar range.
I am just not sure where in the guts they are.This one is just so cheap because it will hardly move and with the economy in the tank nobody is real interested in it. The only ones I have seen close are Komatsu dozers. I saw a real nice 450 loader with a clamshell bucket and rippers in good shape but it was in the 15k range.The Massey is good. I have a Massey roll over box blade too.
It is a real stout one. I haven't seen many new ones close to this one.

I just need to do a lot of dirt work on my 31 acres and the Massey is a bit slow. Some misinformation going on here.I've owned and operated a bunch of small JD dozers,still have a 450D.The transmission is NOT a 'power shift',it's called a shuttle tranny and it comes with a reverser.You put the tranny in gears 1-4 and simply use the reverser to change direction.You only need the clutch pedal when changing gears,NOT when using the reverser.The beauty of the system is that you can shift direction 'on the fly',without slowing down at all and like I said,without using the clutch pedal.
Trans housingAmen, I've seen 4 of them do that when I was around them 7-8 years ago. It ain't cheap to fix either.
They're a fantastic spreading dozer, but don't overload them.You have to adjust that main clutch so it grabs well but doesn't slip. For contracting purposes, I got away from them because they have a lot more power than they have sturdiness, for lack of a better word.
We stripped finals, blew trannys and twisted other stuff by doing stuff they weren't meant to do. I found the D4 Cats to be a lot better suited for our main function, which was clearing cedar trees. I agree d9gdon & Greg:iagree The JD 450 dozers & highlift tractors worked great on the jobsite, but dang.when they break down they are a son of a gun to work on.Not mechanic friendly at all:cussing You have to be thin & double jointed to reach in to the bowels of the 450 crawler When I swapped out the tranny case for my buddy there was more parts & hardware laying on the shop floor than was still on the 450 dozer,whewwweeee!We drank a little barley soda after that job:drinkup John Deere must have hired the Smurfs to assemble the 450's at the factory. I have two 450A track loaders trying to make one good machine.Is it just me or are John Deere parts hard to get.Somethings are available, other parts no one even wants to look for.And i agree with those here who believe the design was lacking.Both machines the Frame to bell housing spacers T23886 And Frame to bell housing bolts T21238 are all broken.Seems they decided to hang the motor - radiator - and that heavy nose piece off the bellhousing by those broken parts.I found a used set of the spacers but the special bolts are a dealer item.Anyone have a good deere dealer to recomend?
