Great pictorial Sean, I am going to save this because someday I will have to do it I am sure.

I agree with Hobo, I would drop the pump amd clean it. I did the clean and flush on mine when I bought it, but I ended up rebuilding my pump anyway. It sure looks like a mud pie in there.
I wish I would have pulled my engine from my tranny when I had it as far apart as I did. Lesson learned I guess.

Lift has never given me any troubles before. Beleave it or not. Good point. Ill drop the pump too. Pretty easy to get at everything now and give it a good cleaning while it is split.

I have and that's the mess i had when i finally dropped the pump. No way you can git under the PTO support and wipe that mess out but some folks don't want to here that. I have also read you only need to git 65% of it out so leave some it will B better than B-4, must B rite cuzz I read it and shore nuff seames the EZ way out. I spec if you have had problems with the relief valve you can see why now. I would have to drop the pump iffin it were mine and clean it also. You mite have a virgin I bet is never been apart. The PTO support is rite EZ to disassemble for a look, don't over look it. Been a while sense I went into one. All the bearings sept the front come off the shaft EZ, stand the shaft on end and bounce the end on a wood block, the weight of the gear will knock them off the shaft. You do nice werk, I like the pix's.


Live by the FO-4 most of the time HOBO. The book says split the engine and tranny first. Most of the post's I have read here say it is easier to roll the rear back. That is what I did. Split the engine and tranny last. I used a motor cycle jack to get the tranny down. Going to use a engine hoist to put it back in. It was a solo job to get it apart. Going to need a second pair of hands to get it back together.

From what I can tell now...I think it is the bearing in the input shaft. Shaft has a lot of play if you wiggle it from the front. Might be normal. I dont know. My first time in a 9N tranny. Bearing seems a bit rough spining. Main shaft spins freely. Guess ill find out. Going to get the rebuild kit from this site and pull it apart and put it back together the same day. How right you are HOBO...I dont see how anyone can get all the sludge out with out splitting. I have done the diesel treatment. Pretty hard to get that sludge in front of the pump. I have a hand full in the rear end I need to scoop out to. I can access that from the hole that the PTO shaft came out of...

Input gear is straight cut. (all the gears are) this is a 41 9N SERIAL #9N79052

Live and learn and split your tractor third party image

All gears look good and no broken teeth :D

Here are some more pic's...Thanks to Tex in Driftwood for the blue tarp... This is a shade tree job all the way... She is under cover waiting on parts...

This is all I found in the void...The clip ring was hooked on the cotter pin LOL the other part was right next to it...Nothing found in the bell housing...I expected more starter parts LOL

I have been know to do things bassackwards, I roll the front away, then remove the trans, But I am not work'n on dirt it mate B better your way . I would not follow my recommendation on giving the hydraulic sump a good cleaning I would go with the flow and leave 35% of the crud in their. After all I am out numbered and feel it best to play along. I have got into to much trouble and had my tail spanked by BIG DADDY UNDERSTAND. Your pix shows why a Spray-Wipe and go is a wast of time, but good enuff for a bunch of know it all shade trees. It mite B best if you throw a nutter hand full of dirt in the hole, it does not need to B clean. Why would one want the best for their tractor when they kin haffarse it.

Right click them and save them to your hard drive.

It was pretty easy. Im going to need help when I get ready to put it back together. I rolled the rear section back from the transmission. going to use a engine hoist to left the tranny out.

Yup -- very useful indeed. Now if you forgive a dummy question...do you roll the front away from the back, or the back away from the front, or which ever is easier? (I don't imagine either method was easy on that soft ground there!)
