Cockshutt 30 frnt engine seal

Been working on a restoration project, cleaning prepping for paint, in process removed fan belt pully off crank. Was kinda a hard pull but that a long story for a different post. When I first brought tractor home and got her loose and running, had sat for 10 yesrs, front seal leaked a little at first but sealed after running seveal times and getting some oil to it, assumed it was probably a felt or leather seal and just dry. Question is now since I pulled pulley, is that what the seal seals on or is it further in on crank? and if so what are chances that it will still be OK and seal again after reassembly or is it wisest to change seal now since I'm about half there anyways. Opinions. Thanks Rocko.
 
The seal lip is on the pulley hub. You should be able to see a mark or groove where it contacts. If it wasn't leaking you can put it back as long as you didn't nick or damage the pulley suface. A new seal would be best but they're pressed from the inside. You have to remove the front cover, which means removing the front engine mount and governor. I hate to see a nice paint job spoiled by oil leaks.
I went through this with one of mine. I used a Speedi-Sleeve from CR Seals but it only helped a little because the crank is so loose.
 
Thanks Mike, I was looking at it a bit closer today and I could see, well more feel the lip of the seal in there, not easy to see with the shaft in the way. Got local Agco suplier checking on availability. Haven't check manual about process yet but thinking I will go ahead with changing it. Engine is out of frame already, was just easier to pull it for clean and prep. So that turned into new clutch. Never figured to go to this extent when I started on this project but with each hour I put into it it seems dumb not to go one step further and do it right. Like a snowball just keeps getting bigger but I quess thats the way it is when you catch this nasty sickness called TRACTOR RESTORATION. Thanks again Rocko.
 
Rocko,

On the inside of the cover where the seal goes, originally it had a felt "washer" and the seal that you know of. Quite often the pulley will get a small grove worn in it from the seal and can leak anyway. The reason I mention all of this is that there is plenty of room to put in 2 seals, 1 right behind the other. I don't know about you, but I hate oil leaks. I have done this with my engine rebuilds and never had a leak...knock on wood. I believe NAPA has the seals, if not, I know Phil Heisey has them.
 
Mike read through manual this morning and doesn't even mention govenor removal although in pics it is removed. From looking at govenor appears govenors going to come off in 2 or 3 parts, correct? Any special precautions when performing this removal, new gaskets needed , if so can I just cut them myself from gasket stock paper?
 
The governor will come off in two pieces. Check the manual for lining the shaft when you put it back on. When you put the front cover back on, the five screws that fasten it to the oil pan should have copper washers. When I took my 6-230 apart they were mixed with the lock washers.
 
Mike, read through the manual, not possitive as to what your referring to as to lining the shaft, could you elaborate on this a bit. Saw the screws at the bottem, 4 had copper washers that are squished to the point they won't come off bolts, 1 had a small rubber O-ring on it that was near eaten away. I'll need to hunt down new ones. Inside found hay wire where I'm assuming should be a C or E clip on the small shaft that houses in front portion. Old girl has had a fair bit of surgery I wasn't aware of till I got this deep into her. Thanks Rocko.
 
Rocko,

How did you make out with that seal last week. Sorry I didn't answer your last post. These things come up in reverse order in the forum.

The rear section of the governor housing fits into a bore in the spacer plate but there is nothing to align the front section. When you install the front you're supposed to move it around until there is no binding of the shaft in it's bushing. Just common sense.
