JD 440ic question about right track not working????????

Crawlerbrad · Post by **Crawlerbrad** » Tue May 26, 2009 3:48 pm

just to get started i am new to crawlers and have never had or worked on them before. i have restored jd tractors before but that is it. ok soI just bought a JD 440ic from a buddy of mine for next to nothing. it runs but needs carb cleaned and a few odds and ends. He was tell me that the right leaver did not work. i was messing with it and noticed that when you are digging with it, only the left track turns. the right track does not work. So there for it only turns right, because of the right track not turning. I am thinking that there is a broken shaft or pinion gear???? I am slos thinking that it is going to be a bigger job then i want to handle. or maybe it is something simple?? any help would be great. thanks

Welcome to the most fun ever had with your clothes on!

Most on here surpass me in knowledge and experience on these, but yousr sounds like it could be as simple as the right clutch pack.
You have three clutches in these; the main tranny clutch on the foot lever, and each handle operates a clutch going to each sprocket. The clutches wear out, get oil on them, etc.
Hopefully this is what it is not some major broken parts.
I will leave the rest to the ones ahead of my knowledge.

thanks, i am thinking that the brake is bad or needs adjustment. but the big question is that going front or back both tracks do not pull. only the left track pulls. I did pull the cover on each side under the seat that gets you into where the adjustment for the bands is i think? off and saw where you can adjust how far the levers come back toward you and i noticed that there was somekinda of oil in the left side and nothing in the right. I would think that there should not be any oil in there where the brake bands are because of it not braking, but slipping, but on the other hand i would think that there should be oil in there because of lubeing up the gears and shafts. again thanks for your reply. it is all helpful.

throw out bearing may be set too far out and disengaging right steering clutches. Maybe oil soaked. clutches maybe too worn and need replaced. All of the mentioned above can be seen in the access holes uner seat on right hand side and one behind right foot. Not that hard of a job, but I would suggest a service manual, well worth 65 dollars give or take. Lavoy on this website will lead you in the right direction and he has all the parts you will need and he is great to do buisness with. He will not try to sell you something you don't need and get you back to playing in the dirt.

thanks i looked in there but not knowing what i am looking at it is alittle confusing. i am working on getting a service manual. I am going to get that before i start working on it.

As 440Dozer stated, the service manual is a must.

i have a jd 440icd and had the same problems your describing. the culprit in my case was a bad seal on the final drive. it leaked the oil all out onto the clutch plates of the final drive and therefor it only slipped when power was applied. It would also not respond to the pull on the lever as the brake band was soaked as well.

i fixed mine, and had even less experience fixing this kinda stuff then you have.

is there lots of oil around the final drive housing?

i think that it may. i will have to look again. i did take the plate off that is under the seat and the letf side has sometype of oil in it. it is not full but i can tell that there is somthing in there. and the right side looks to be dry. no oil in it. i to was thinking that the problem with the left brake not working is that there is oil soaked maybe a bad seal??? and the problem with the right track not turning is the clutch is stuck open you can say??? i will be tearing into it in a couple of weeks. right now i am working on the water pump. and am having trouble getting the retainer out of the housing that holds the bearing in. i did press out the bearing anyway and all it did is break the bearing in half and still half in there and can not get it out.

i am pretty sure that there shouldn't be any oil in there at all. the oil gets in between the clutch plates and then they don't do what they are suppose to do. when you pull on the lever the throught out bearing dis-engages the clutch and the brake banks grabs the wheel. this stops the track from turning and stops the power from being applied to the track.

like i said, in my case the final drive has a seal that went bad. the part cost is cheap, but the work to fix it, took me a long time.

get the manual, i was able to buy a cd from someone on this site that down loaded in pdf format the manual. i will look for that info and forward on to you
