B2400 Rear end trouble

[Behrend II]

I just experienced a BIG problem. While moving snow with my back blade the rear end locked up momentarily and i heard a clunk. I then noticed hydraulic fluid pouring out rapidly. Upon inspection I notices about a 1 inch hole in the housing (near the drain plug) and ALL the fluid drained out.

The hole is from the inside out. I assume that a gear (or something) broke free and jammed against the housing and popped through. I know it's bad, but am wondering how bad. Anyone have any experience with this?

Im assuming this is a hydro tractor and the drain plug you speak of is the one under the mid pto? There are also drain plugs on each side of the rear axel.
I recently split my B2400 for a hydro-pump repair and saw some of the inside gears. This is not good.
Do not run the tractor at all with the fluid drained out.Dont even turn it over cause you will burn up the hydro pump in a matter of seconds
I can look at my parts manual later and see what it could be. This has me wondering.

Where you working with the diff lock?

I had a friend in high school whose Dad would always joke that the "check engine" light never did you any good and that you should keep running it until something broke THEN you would know what was wrong.

This is not one of those times!

Checked out my B2400 parts manual, did this occur in the center section of the rear axle housing or the right or left side where the plugs are?
For what I can see, an object from the area above the right or left axle housing came loose or broke off, say the brakes, and fell into the main drive gears attached to the wheel axles (L or R side) ,got jammed between the gear and the bottom of the axle housing, locking the rear-end, then enough forward force drove it through the housing.
Where there any parts on the ground?
Just my theory.

I'll have to take a closer look at it in the daylight tomorrow, but I think it's on the right side next to where the draw-bar inserts. From back to front, it's about 6 inches in front of the female draw-bar receptacle.

I wasn't using the diff. lock at that moment, but have used it recently. The clunk I heard prior to it happening sounded kind of like the sound of the diff. unexpectedly disengaging or engaging.

 

[Behrend II]

Sorry, yes it is a hydro and I think I mistakenly thought the bolt head from the axle housing was a drain plug.

WOW, this sounds expensive.

 

[Behrend II]

Anymore thoughts anyone?

No. The ones I've got are bad enough. Keep us informed as the investigation plays out. Thanks.

I will - I'll probably find out that there were some obvious warnings of the impending disaster that I failed to recognize. Maybe I can save someone from a similar fate

At least you see a little good in everything. Not a good time with the snow coming. Let us know how it works out. Hope it's not too bad.

I had a mechanic that I know take a quick look at it today. Without getting inside and looking, he is speculating that a bearing may have broke free and been pushed through the housing. Next step: splitting it open and assessing the damage.

I know this tread is 6 years old, but I was wondering if this was ever repaired, and what the problem was.

He has not been on TBN for a little while, you might be able to get a reply back by sending him an e-mail (possibly, he'll get an e-mail notice that someone replied to his thread - but he might be like me and have that feature turned off.) :2cents:
