440 reverser

tuney443 · Post by **tuney443** » Sun Apr 27, 2008 7:47 am

Just got a 440 with a 831 loader.Seems to run OK, but need some advice on that reverser.Seems to me that when you pull the handle up,that should be forward, but on mine,it feels like something is wrong,I see the spool moving by my left foot,but nothing is engaging.Now what is strange is that I have all 5 reverse speeds but only 1 forward speed by pushing the reverser lever downwards.And the forward speed,I have to have the tranny in R.I know this can't be right---anybody?I definitely need all the manuals for the new kid on the block.

That is right when the reverser is in the reverse position, since the drive is reversed twice by the reverser and then by reverse gear so it ends up forward. Unfortunately it sounds like the forward clutches are not engaging so you have no forward direction. Someone else will have to tell you more, I don't know anything about the clutch reversers.

With some luck, it could be the adjustment for the front clutch pack. If you do not have a service manual, this would be one of many reasons to own one. Someone on here has produced CDs of some of the manuals, or you can just buy the book.
Here is the other thing. Unless you are wanting to take your crawler apart to replace broken parts, do not run it in "reverse" like it is, which is the only "forward" that you have right now. Especially do not put any load on it if you run that way.
It is designed to go just as fast in backwards as it does in any forward gears, but running it in reverse to go forward is a good way to spend extra money.

First thing to do is go through the entire reverser clutch adjustment procedure. The manual is a bit of help in that. It does sound like you have the rear clutch fully engaged, and the front cluthc is not engaging at all. When you move that lever, it is supposed to dis-engages teh rear, and engage teh front cluthc all at teh same time. If that is not happening, then you need to go through the adjustment procedure. Once that is done, post teh results, and we can give more direction.

I don't have a web-copy of the manual for teh adjustment procedure, but if you do a searrch on this site, I beleive that it has been spelled out before. If not, let me know, and I will walk you through it. I am not an expert on the reverser, but am becoming a 'guru' for sure. I have had mine apart several times, and am putting together a repair procedure for them, complete with pictures. Should be done with that next month.

Toivo1037,

The reverser procedure with pictures will be another great asset to this site. Thanks for taking the initiative to produce that for us. Looking forward to seeing it.
I don't claim to know much, but I am learning what not to do to them which saves money, time, and headaches. LOL

Thanks Toivo---it's bringing back bad memories of the adjustment procedure on an old 10-12 ton Huber roller.Yeah,I've got to get those manuals ASAP,either from the previous owner if he has them or here.New toy seems real small parked next to my 450D dozer.

Here is a scan of the adjustment procedure on a 440. Let me know if you don't understand it or have any questions about it.

With the 831 loader on the machine, adjusting this reverser clutches can be a real challenge. The front clutch is not too bad but I had to figure out how to make the adjustment using only one hand since I could not get both hands into the area. With practice you can make the adjustment on the front clutch. The rear clutch adjustment with the 831 loader will try anyone's patience. It took me hours to adjust the rear clutch one notch.

If anyone knows any tricks, let me know in case I have to adjust them again.

Rear clutch, either remove the right foot rest plate to get from the top, or go at it from underneith. Front clutch figure out how to push the button in with a screwdriver, then while pushed in, you slip the adjustment ring up/down.

Thanks Toivo. I hope that will work for mine because I don't recognize those pics.My reverser handle pivots down by your left foot and has a grease fitting.Why did Deere make this adjustment so difficult with the loader?It's a redundant question--I already know the answer.
