Blown T-Case

[jeepjunker]

Just bought my first M715, and started with the useual poking around, seeing what needs what. So i decided to start with the fluids. Front and rear diff fluids looked ok, no broken teeth of chunks of metal at the bottom. Next i pulled the t-case plug and pudding started ozzing out, i stuck my finger up the drain hole and i could feel rollers from the bearings at the bottom.
So i was wondering were a could score a t-case rebuild kit, and how hard it would be to assemble. Im a good mechanic and am very neat and picky about my work, and follow directions to the T, i just never rebuilt a t-case before. So any help would be awsome. Thanks

Are you going for a full resto? If not get a np205 and just upgrade.

[gimpyrobb]

Yup, unless you want to travel less than 50mph, get a 205 and never look back.

My "vote" is for a 205 also...

Reads like someone filled your T-case with grease and a little oil to overcome the noise. However, the T-case is not as bad as the stories about it. The interior is made of proven parts. The bearings are available at a fair price. These are standard Timken bearings.
If your rollers were in the sump, a bearing housing must have been broken. However, normally they have no chance to fall down. So it seems to me, that someone during assemble dropped the roller of the front axle drive shaft and did not care for that. Use some grease to install them before inserting the front axle drive shaft. That works, I did it the same way.
Dripping T-case means a clogged ventilation. Than the pressure builts up that much, that the oil passes even new (and I mean with new not NOS, I mean realy new radial seals on propperly reworked flanges surfaces) seals.
Good luck!

Depending on what came out...it could have had water in it that got whipped into the gear oil...nasty stuff can come out after that...

We have a page on the rebuild parts:

Brandon (rpgdeity) just rebuilt one for his fathers m725. He could probably shed some light on what needs to be done. He did say that the pre load of the bearings is very important.
There is a company that sells a complete rebuild kit for the np200 here in Portland Oregon. I do not remember the name, but it used to be listed on this site some where.

if you take it apart and it has broken hard parts, I am thinking there are alot of these cases around cheap since everyone has upgraded to the 205, it should be a buyers market to pick up one.

good luck
