800 series front axle bushing replacement

So I have gotten past my generator issue and I'm trying to get a new pivot bushing installed in the front axle. I peeled the old bushing out with an air chisel and did a light clean out of the hole. I started the new one that came from Steiner. It went in about 1/4 of the way and now is refusing to budge. I heated the axle with my mapp torch and tried cooling the bushing while I had an 8 ton bottle jack pushing on the grill guard. All it did was flex the front axle assembly. I dug out the service manual and it just says to replace the bushing but doesn't give any installation advice.

So what methods have you gentlemen had success with? I'm at a bit of a loss as I figured this would be an easy install.
 
I'm wondering if you maybe have the wrong bushing, or one not quite up to spec...
Did you by chance measure the bushing and bore?
Shouldn't need to heat the axel but freezing the bushing first if it's a real tight fit will help.
I just ordered one for my 861, I know on my 8n I didn't have any issue's getting it installed, I don't remember if I hammered it in with a block or forced in with a big clamp and oiled it first.
 
You need a bushing driver for that job. I have one a friend with a lathe machined for me. Prevents distorting
the end of the bushing while driving it in place. Clean and measure the bore to make sure the bushing is
correct. It has to fit tight so, a good driver is a must.
 
After thinking this over a bit more I do agree with ofm that yes a driver would be handy but sounds like your bushing found a high spot from the air chisel.
Or it tipped a little bit and is now jammed in the bore and I think you'll have to remove it and start with a new bushing, just check the bore closely for any galling or ridge.
I did measure my axel bore ( 1.19 plus) bushing is 1.193 so it will be fairly snug, your old pin would maybe work as a driver or most chain auto parts stores have rental tools and should have a driver set.
I did find a set on amazon pretty reasonable 28 bucks.
Best of luck!
 
I haven't done anything more with it yet. I'm going to get some 1/2 and 3/4 shank bolts to use as pullers. Right now I'm planning on shaving down some large fender washers to use as a puller to remove it. After that I'll run a flap wheel around it a few times. We'll see how that goes. I think when I'm pushing against the grill guard I'm loosing quite a bit of force because it's attach so far away from where the bushing is at.

I did clean up the chisel marks with a half round file before I started the bushing. I didn't take any measurements before putting it in so I'll look at that while it's out.
 
As a follow up. I did pretty much what I outlined in the last post. I wire wheeled inside the hole then ran a flap disk around and used a 3/4in Grade 8 bolt to pull it into place. Then I honed to a nice fit per the instructions from Steiners.

What I'm thinking right now is that I had some rust jacking build up in the hole and I got that cleaned out. It really didn't take that much force to pull the bushing in after the clean out. It should be good for another 65 years now.
 
I took my bushing castings....unbolted them from the rest of the front axle assy.....to a machine shop and they pressed them in for a
small fee.
