Got a new to me lift cover for Dad's 2N. Needs rebuilt with new bushings and cleaned up.

The one on his tractor had a user installed port drilled in the top cover to steal lift pressure for a hyd hose, problem is the JB weld or whatever they used to seal it up blew out, after cleanup we discovered threads, so put a bolt in it for now, hence the new cover I'm trying to fix for him.

1. I can't get the T bolt on the spring to unscrew off the back of the cover. PB and heat applied and now a few more rounds of PB.

2. I took one lift arm off with a puller and the manual says to drive the shaft out with the other arm on it, no luck so far, am I missing a pin somewhere? Have used PB and let it soak. Using a chunk of 2x4 as a buffer and a 5lb hammer with no luck. Don't want to damage the shaft if I can keep from it.

3. This cover came off of another 2N according to serial it was a 46' but it has the piston with just the one o-ring and leather. I thought that it was supposed to have the piston with the 3 rings?

Any help is appreciated, this the first N I've worked on.

Dean said: (quoted from post at 10:09:58 03/14/15) It will be easier with both upper lift arms removed as you can now drive it either way.

I usually free things up before removing the lift cover from the tractor as the tractor is an ideal "back-up."

I remove the fenders so that I can wail on the rock shaft from either side with a 4 1/2 lb. hammer (larger if need be but usually not) and a good piece of hard brass.

The same technique can be used to free up the upper lift arm(s) and the ram arm.

Upon reassembly, turn the rock shaft end for end so that it will wear on the opposite side.

Whut he said... I seen the post but with the cover off and one arm on It did not register in my brain how to tell you how to support the cover... With the arms off as JMOR posted...

Dean's tip on flip'N the arm is a great tip... I doubt knock'er loose in a rattle can is going to be much help... I have had good success using a air chisels with a hammer bit to ratte'em apart..

Last time I had to remove a rockshaft I wasn't in a hurry so I left the lift cover on the shop floor with a can of Kroil and a big dead blow hammer next to it. Every time I walked by I gave it a shot of Kroil and a major whomp with the hammer. After about a week of this treatment, one morning the whole thing slid out as if it had been buttered... you just never know!

If you have good threads, put a plug in it with sealer and forget about it.

The piston has been replaced with the newer style NAA piston.

It is a fairly common upgrade on the N series tractors.

As far as getting that rock shaft out goes, I'm surprised you got

one of the arms off with a puller. I had to use all the heat I
could get from an Oxy/Acetylene torch set with a Rosebud tip

and a 20 ton press to get mine out.

The center section where the dogbone hooks to was also splined

and had to be heated to get it to press out.

I just looked up my post in the archives but the pictures are gone.

Hobo has some posts I remember about the process too.

I'm sure others do as well, I'm just not remembering them all.

Quoting Removed, click Modern View to seeHobo's procedure used a hyd press & remember the support has to be large enough to accommodate the bushing as it has to come out with the shaft due to the large splines for the rocker.
