PTO shaft seal leak

[Soundguy]

It varies from machine to machine, depending on your pto shaft / stub.. etc. Some 2-speed pto units with swapable shafts ar a little more involved with the gearing.. but then some are pull out/slap back in.


( on an 8n you can park nose down in a ditch, pull 4 bolts and slid ethe whole assy out, pay 100$ and slide a new assy in, and put the bolts back in and never loose a drop of oil.. take you about 5 minutes if you are lucky!.. don't count on your 3910 being that easy.. but should be easier than a 2-speed unit if yours isn't. )

By the way.. RickB is -way- more knowledgeable with the new machines ( read: 1965 and newer ) than I am. Most of my daily hands on work is wit the N and hundred series stuff. Rick can probably rattle off the seal number and tell you the in/out from memory on a newer machine like that.

Thanks again. I'll take a close look tonight. I have a 1 speed PTO.
BTW, the seal is part number D9NN703BA

Grab the stub and give it a few ynaks before pulling it.. you will know i fthe bearing is bad immediatly.

Soundguy,
Well, I went and bought the PTO seal, at a whopping cost of $4.76. It cost me more in diesel for the extra mileage 40 miles out of the way to get to the place. But it was worth it, nice folks, took the time to answer my stupid questions, and I got to look at some new Mahindra tractors. Saw one with a cab and A/C... looked COOL

Put the seal on today, couldn't really see that anything was wrong with the old seal, we seem to think it was the inner "race". It has a sleeve with rubber on the inside, that seals against the pto shaft, guess the rubber was getting too thin. Got the new one on, filled her with UTF and we were off and running... I mean tilling.

Man was it hot.... it hit 99* today, but it was a god day. Got the tilling done, that Yanmar RS1303 tiller does one **** of a job. It took time to till
a 1/2 acre garden but it's done.
Later,
Ted

Sounds just like an old TO-20 I once had

The to-20 and 30 share an identical hydraulic pump as the 9n / 2n.. 8n is a lil different.. but same procedure applies..

It was a pain tn the @#$% to work in. Bhe best I remember the hydraulic pump assy came out from the bottom of the tractor. Very very heavy. I can say with a smile I'am glad it's gone

Yep.. you pull the pto shaft, and then you can drop the pump which is affixed to the bottom cover..

I have an E14 D Hinomoto tractor with a PTO seal leaking doe's any one know how to change this out? Is this going to be a huge job or a simple one? I have pulled the four bolts that hold the round plate that the shaft runs through. I can only get the shaft and the plate to come out 1/4 of an inch. Do I need to put something in gear to pull it out does any one know?

get an expanded or exploded diagram of your rear section.. make sure there is no spring clip or similar holding it in that you need to remove via some access panel.

I'mot at all familiar with your model.

the older and different make machines i'm familiar with mostly have slide in / out shafts, though a couple do have some 'gotcha's' you need to be aware of, like thrust washers that drop out of place when the shaft comes out

if you get the diagram.. post it.
