Best way to remove and replace pto oil seal on D14

At the dealership we used to keep a pto seal flange hanging on the wall and would install a new seal and o-ring in it on the bench using a punch to knock it out from the front of the flange. This allows you to make the switch quickly with minimal oil loss. I think we used a couple dowels to help line things up quickly and lots of grease to protect the seal. Look over the shaft for burrs that could ruin the new seal when sliding it on. Otherwise you could drain some oil to do it mess free.

What do you mean by front? The seal I'm referring to is at the rear and you remove the seal flange from the rear. Leave the shaft in, just pull the seal flange. There are just three bolts to remove. If it's leaking that bad and you don't want to lose your oil then park the tractor and drain oil into clean containers and wait for new seal and o-ring.

Yeah it's simple..if I can do it !!

DRAIN OIL FIRST !
I say AGIAN..
DRAIN OIL FIRST !!
if you don't well, let's just say I told you so....

Now, remove the 3 bolts and wiggle the casting off, replace seal, replace casting and 3 bolts, put oil in....
If there is room...slide an O-ring(or 2)  onto the PTO shaft before all the other steps. It acts like an oil slinger,keeping some oil away from seal. Well that's what I was told, made sense to me, course this was AFTER I'd done mine.....

Keeping some oil away from the seal with "slinger" O-rings???   Your advisor is pretty ignorant, because the seal is completely submerged in oil.

no comment, JB IS TOO MUCH

Is there a gasket that needs replaced when doing this?

Just an O-ring and a seal. Pretty self evident once you see it apart. Make sure you put the seal facing the correct direction.

I did as Clay mentioned, large HD jack stands under rear axle housings but I had front wheels off and front hubs sitting on 2x4 pieces.

Clay wrote: I have changed these seals with very little, if any, loss of oil.  We park the tractor on a very steep hump, with the rear wheels up hill.  BE SURE to adequately block the rear wheels and set the brake.  If necessary, letting the air out of the front tires will give some additional advantage.   CLEAN the area before removing the three bolts and the plate.  As others have said, check the shaft for burrs. If the fluid level is really high, have a drain pan handy.

Did that once too on Dad's 190XT when he was out round baling for someone. It worked with just a little oil loss. If you are fast you can do it without the hill but if there is a hang up with getting it together it will be a mess.

 Just drain rear housing (probably needs to be anyway ) take the 3 bolts out of housing n remove plate leaving shaft in tractor .(this way u do not need to drain P/D housing )         

Thanks for all of the replies and especially the photos.
