1010 rockshaft seal

Is it humanly possible to replace the rockshaft seals without removing the whole rockshaft, just the lift arms?
Early 1010, and I only have the parts manual.
I have the seals, but my leak isn't really worth taking the whole assembly apart ... again.
Basically making it into a parade queen, excuse being to plow snow off the driveway.
Thanks!

(Apologies if this gets posted twice.)

If your referring to the seal at the very end of the rockshaft where the arm meets then yes you can as I have done that before. Just make sure that you press the seal into a little bit different location so the sealing lip is on fresh metal.
 
I'll definitely check the play when I get the seals out, hopefully tomorrow.

The rockshaft does have about 1/4" end-play, which obviously would be hard on the seals. That's apparently controlled by the lift arms, and I'll clean up the shaft ends (seal surface and splines) and lift arm splines when I get them off -- they might slip on further. Should I stick some kind of shim between the housing and arms?

These hydraulics haven't worked since I got the tractor, so I don't really know what I'm getting into. But the internals looked good, over a year ago. (I even found a new gasket!)

I just got the pump sorted enough to give the lift arms an erection, with only dripping leaks from one lift arm. I don't know yet whether it has proper power, though. The pump did feel good and tight when I spun it in my hand. (Tractor is manual steering, but pump has the power steering circuit. Dunno.)

I haven't purged the pump, and it's cavitating real bad (foamy oil). It was sucking air at the return line, but I got those new seals in last week, and no leaks yet.

I trying to say that I want to fix the lift arm leak before filling it right. (I don't know how to drain it either, without making a big mess.)

Continued thanks.

I've replaced both seals on mine and I wouldn't recommend doing it w/out removing the rockshaft. Getting the old seal out would be a pain and putting the new one in correctly would be equally as difficult. As in more difficult than removing the rockshaft.
 
Well, I can't get the lift arm off without heating it up -- too corroded on the splines. So I'm blowing it off for now. Isn't actually leaking right now anyway.
Thanks!

I had leaking seals last year when I put in new fluid. The fluid hadn't been changed in years I am guessing and it was low. The seals on mine leaked for a while but eventually sealed up. I also think I may have over filled a bit. The only time I noticed a leak since then is if the tractor set parked on un even ground for a period of time.
 
I think mine leaked because the pump was sucking air and foaming up, plus I overfilled it. Too much pressure. Not leaking today.

I've salvaged leaky seals with SealMates (http://sealmate.net/). I've made them from the tough stiff clear plastic that some parts come packaged in. Basically, cut out a little hook (I used scissors), slip it between the cylinder and seal, and pull out the crap that's keeping it from sealing. Amazing, how often it works.
