I need a seal, what I call the imput shaft seal that seals the spline into the rear end or the hydraulic pump from the drive shaft. Where can I get one? This is for a MF 1655. I know it is called something else, I don't have the time to look it up, got to go pick up the kids frkom school. I drive school bus.

Thanks
Dan

I replaced that seal on my 1855, over at the shop in my toolbox I think I have the seal part no. , I always save the box top with the brand and part no. on it for any bearings or seals I buy, then write on the back what it fits. Try to give you that no. tonight, today is going to be a long day at the shop (one man short, he's getting some medical tests done) so I'll have to open and close. So much for semi-retirement!

Thanks for the info Tinkerer.

Butch I think you are the ticket, if you have the number on the seal and bearing as well that would be fantastic.


Greatly Appreciated

That's the one, thanks Larry much appreciated. Don't need the bearing, just thought it might be nice to have that # for future ref.

Now that I have the oil seal on the way, what is the best way to get the old seal out of that charge pump housing? I have the drive shaft out of the way. Should I take that housing off or is there a way to get the seal out without removing the housing? Looks like there is a couple of plates and a pin on the other side, along with a big O ring, wouldn't want to bugger things up.

Thanks
Dan

When I replaced that seal on my ole 1855 I did take the frt cover off of the charge pump to replace the seal. I wanted to make sure the bearing and shaft were good and it made it a lot easier to change. I reused that big o-ring, on mine at least, it sealed right back up. Watch out for that pin that drives the center gear, it'll fall out of there. If put back together without the pin the tractor won't move, don't ask me how I know this!!

Thanks Butch, I won't ask.;) I have had my share of those adventures. I just kind of figured that would be the best way, make life a lot easier.
