JD 450C Winch

[Jag]

Does any one on this board have any experence with a JD winch. Mine was not hooked up when I got the dozer, and can not get it to go into gear. I hope there is a easy way to deal with it, without sending it to the shop..

I also have a JD 450C, but can't help you with your winch problems. I was just curious if you were able to have your problem with it fixed. I had the engine rebuilt on mine a few years back and it runs great! Other than a few minor problems it has been a great machine. How do you like your machine?

Tedman, sorry to take so long to reply, must have lost track over the holidys... The JD 450 is one heck of a dozer.. love it.. The more I know the more I like it.. It is small enough to get into small places but can still do a bunch of work.. Have not gotten the winch fixed yet, but after getting it stuck once and high centered once, it will get fixed soon before I do something stupid again... I have had the dozer less than a year but have put about 200 hours on it.... This one is an 81 model, it had a complete uncarrage rebuild 150 hours, the 6-way blade pins redone and a tranny overhauled after that, before I got it. I had figured that I would need about a minium of 400 hours work done around the place over about 3 years or so... Looking at my options I decided to buy. I can go on and on about all the good things about the 450.

It is one of the most popular models around, spare parts are plentiful, and every one has worked on them. There a lot more 450's than any other size... I have only had to replace a couple of hydralic hoses on it. One was the original blade lift left cylinder hose as best as I could tell....

The boy across the road has a big D8 cat with a huge dirt blade on it... most likely 100,000 pounds, cleaning off his property and can not work but a small area due to it beening too wet. I can go almost anywhere on mine an still work with out tearing up the ground with huge ruts....

TM, how long have you had your dozer and what have you used it for.... Send me an e-mail, I have a lot of questions...

Hello Jag, in response to your winch problem in your old post you said the winch was not hooked up, did this mean the hydraulic lines to the winch or the winch was not on the tractor, winches are fairly simple you gotta drive them somehow in your case the pto shaft drives it which must be put in gear to work (look around in the floorboard for a lever to engage pto shaft), then you gotta have a couple hyd. lines to it one to apply pressure to the clutches in the winch to make them pull and also one line to release clutches so you can pull cable off. Good luck

Big G-man, ok, a little explanation is in order... When I said the winch was not hooked up, I meant the the control cable was not connected. In other words it had not been used in a while. On this model of JD dozer the winch is self contained. It runs off the rear PTO, which is engaged at all times when the clutch is out. The winch has it own hydralics and filter. The control cable goes back under the seat and attaches to a lever that throws the winch into gear either spool-in or spool-out. It has two large internal brake bands the are released by hydralic pressure before the pressure startes to turn the gears.... It appears to have plenty of fluid and just not used in some time.

On this model the operator lever sets rubbing the right thigh. On a larger person than my self it may be the way and bother the operator when using the dozer. The lever would be very easy to bump into spool-in getting in or off the machine. If the motor is running and you bump the lever it would spool-in and you will have problems.. I was in hope that the cable was disconnected and the lever push up out or the way because the other owner just had not needed the winch and just got the lever out of his way...

When I got the dozer the cable was spooled in and jammed. I was in hope someone would have seen this before and would say the the brake bands where just jammed and all I need to do was set the winch to spool-out and hook the cable on to something and pull it out to brake to drums loose.. or some such. Or just tell me to bite the bullet and take it off and take it in to the shop and have it rebuilted.... It is still not fixed..

Hey Jag, sorry its been a few days since I have been on my ISP went kaput had to find another, anyway your winch setup is a little different than I remember but let me ask a few more ???? bout it, the control handle hooks to a lever under the seat you said, this lever does it operate a hydraulic control valve? the reason I ask is because the winch would have to have a clutch packs in it that free wheels since the pto turns all the time, and the clutch packs would also determine spool in or out function there should also be a detent where you could pull the cable off by hand. And what if anything does it do when you try to operate the winch in either in or out direction i.e. does it pull the engine like its trying to work or anything silly like that, I'm thinking it should attempt to work in one direction or the other since your using a different clutch pack for each direction, and since it has hyd. pressure to the winch, and also since the pto is turning, thats pretty much the basics of a winch, I wouldn't think there would be anything wrong with the internal gearing of the winch if the prior owner unhooked the linkage just to get handle out of the way.

Mr G-Man, I do have the shop manual for the dozer and it does cover the winch. The lever only had three positions, in, out, an nutural where the brakes lock it down. I do not believe that it has a setting where it free wheels - can pull the cable off by hand. You said that it has hydro pressure to the winch, no here is not hydraulic connection to the winch, it is self contained. The case is the hydralic tank, pump is internal, and there is no way (I guess, the manual does not cover it) to know what is happening inside.

With the dozer at idle, I slide under the winch and reached up to the lever where the control cable attaches and moved it to each positon, and could not tell that any thing happened. Like I said the cable has been spooled in and jammed.

Hope you can come up with some suggestion or more questions to uncover something. THANKS

Hey Jag I'm not being alot of help here am I??? lol if your certain the pto shaft is turning the winch then free the cable and see if it works, the spool out position would be where you pull the cable off by hand, if the winch powered out it would require 2 people to operate the winch one to carry the cable and one to work the winch lever. Good Luck

I have a JD 350 with a winch and it sounds like the same thing. Mine has 3 positions for the lever. Up winches the cable in, center is brake and down is free spool. There is no power out. When I wind mine in too far and it binds, I hook it to a tree and drive away in free spool. This has always worked for me

Thanks, MR. Regional Redneck... I will give it a try as in a day or two when I get a chance to get back on the dozer. Whe have had too much rain and still very wet to work...
