R/F WHEEL LOCK UP

[CHUCKWAGON]

I have a 2430 4 x 4 farm pro. My right front wheel will lock up from time to time. When I notice it sliding (locked) I back up a few feet and it seems to be ok. Any suggestions on what's causing this problem. I'm confused /forums/images/graemlins/confused.gif My tractor is just coming on 250 hrs. Thank you Chuck..

Chuckwagon,

Are you in 4x4 when this happens? Eitherway, I think I'd take a look at it before more damage occures.

There's a lot of folks here that can help determine what's going on and get it back together.

You mentioned that it only happens on occasion, and you have a lot of hours on it.

This seems like a warning sign that something needs attention. With that many hours something may be wearing out, There are some very experienced folks here to help in case a dis-assembly/inspection is in order.

When was the last time Front Differential was drained and Lube changed. Even if done recently I would drain it again into a pan that will allow inspection of old fluid. Check to see if it's torally contaminated with glitter (Metal Grindings) as that would mean something needs immediate attention. Check for white paste in the old oil as this could be a sign of water and may lead to rusting parts. If not too contaminated with metal grindings would put fresh lube in there and see how things work. You may get lucky!

It happens when I'm either in two or four wheel drive. The first time is when I was haying my fields last yr, then every once in a while there after. ( maybe 4 times all together) I'm not sure if any one else has had this type of problem. I'm just not sure what's causing it. Other than pulling that wheel assembly apart to find out. Another thing to keep me busy. /forums/images/graemlins/grin.gif
I will be giving my tractor a major service before the work season starts up this yr. Not quite 250 hours on it.

Drain and remove the diff cover. It might just be a chunk of something that's jamming the drive gears occasionally. Like items 12 and 13 in THIS PICTURE. If not, you might have to open the right side. Drain is below the hub. Junk may be jamming items 29 or 47 in THIS PICTURE.

Guess I'll be the bad guy here and say it sounds like one of the miter gears has a borken tooth. When it gets out of sync the teeth lockup on each other. You'd have to tear it down and have it look at it anyway as this is not a good sign.

I have to agree with above posts. It does not sound good. Maybe, just maybe if its a piece of "something" wedging between the gears it might not be costly. If you continue using it the way its acting then more damage could occur especially if you force it.
I'd avoid using it until I investigated it more. Its not too big a job to do.
Keep us informed.

Since it does not do it all the time,I think that something is loose in there,we have seem one of the two bolts that hold the driving gear on loose,I would take it down sooner than later before it mess's up more parts

Mr.Fixit:

If it's worn out at 250 hours, it must be made of swiss cheese. 250 hours isn't even broken in.

Sounds like a real problem. Here is a link to Johns Jinma site that documents a front axel repair on a 254.

Good Luck.

That was my repair. Very easy to do. I almost missed the damage because it is hidden inside the large gear. Do not be afraid to open it up. Let us know what you find.

Sorry it took me sooo long to get back to everyone, had a hard time loging on. Ok what your telling me is what I was afraid of. /forums/images/graemlins/crazy.gif I will tear the front end down as soon as the weather alows me to, and will post my findings. Thanks for your input and direction on what's needed to correct this problem. Till later play safe..

Any roller bearings in there that might have let go causing binding / extra parts circulating?

Sounds to me that Rick and Greg are on the right path. Not only going out of sinc, but a broken tooth getting caught between the miter gears, stopping operation. Makes sense when you back up, you are dislodging it and it falls from between the miter gears, allowing operation again until next time it finds it way between them.

Assuming this to be the case, I would start with the inspection of the right wheel gear mechanisim, as a broken tooth in the front differential would likely cause both wheels to lock up instead of just the one.

put it in 4 wheel drive and raise the front end. Turn off the tractor. Rotate one front wheel and then the other, The opposite wheel should rotate the opposite direction. YOu are feeling for any roughness, catching, or locking up.

That is the best idea of all !! it would only take a few moments to see where the problem is. Great idea. /forums/images/graemlins/smile.gif

That is how I narrowed down my problem. It is now posted on John's site.
