Does anyone have images of sector gear popper?

I did a search and came up with 2 links, but they came up "page not found". Any of you gents have a more current link to those pictures?

I'm having me some well, you know fun trying to break the sector gear loose from the vertical steering shaft. I tried the wood block and hammer method and just wound up with wood chip all over the floor. Don't have any brass or copper laying around. The gear feels like it's welded on. Wouldn't be surprised if sector gear has remained unmolested since factory installed 60 plus years ago. Oh BTW would heat help break things loose?

Maybe find some harder wood too.

TIA

Jack the front off the ground. Leave the wheels on they help pull down. Put a bar (wide and flat) under the bolster and on top of the bolt flange of the bolster shaft to pull down on it by leverage (two people may be easiest). Use a piece of aluminum (T-6 is nice) as a buffer for the threads. Leave the nut level with the top of the threads. Heat the sector with a hand held propane torch (for 10 minutes) to heat it. No MAPP gas or oxy-acetylene. Strike the aluminum with authority. Jim
 
What worked for me was all that, plus having my wife turn back-anc-forth-and-back-and-forth on the steerng wheel as I pried up. Helped break it loose.
 
I was at the point you are when I repaired my H.

Like Janicholson said, leave the wheels attached as it adds weight to get the gear loose.

Turn the top nut loose so it"s even with the top of the shaft, lay a piece of hardwood on top, take a big maul, hold the handle verticle, then drop it vigorously on the hardwood. With my 16 lb maul it took a couple hard drops and the shaft dropped down nicely.

For gosh sakes, don"t take a swing with the maul! And don"t use any soft wood which might be your real problem as it absorbs too much of the blow.

Thanks guys. I understand what you're saying. The bolster is a spare and not on the tractor. The one on the tractor I will have to do later. (gasp!) I have it suspended held up by my motor lift. It's tilted slightly resting on one of its bottom corners. My other problem is that I'm a bit isolated and a little short on help. I'll just keep slugging away with some harder wood. If it remains stuck, I'll make a round to the local machine shops for some t-6.

The I&T service manual says to use a "suitable puller" quote, unquote. Oh really, I wonder what they mean by that. The pullers I have don't fit, don't work.

The gear is close to the sides and bottom of the case. The puller would be very special, and hand made. Wood is not going to make it happen. Milsd steel plate held very flat across the nut, and hit flat and square will be a good start. Wedge under the flange to put force on the shaft. Hard wood cut into wedges and used opposed to each other would work to put force on the shaft. Heating the gear is near mandatory. Jim
 
Thanks for your help Jim. I finally got er done. The method I was using was just too half a$$. Suspended by the lift at a tilt resting on one corner was not stable enough. I set it flat upright on 2 4x4s to clear the bottom 4 bolts. Then i found a piece of well seasoned rock hard oak, and that did the trick. I used a short handled 8 lb maul that I can swing pretty good with one hand, and after the second blow, it gave way. Boy, what a relief that was. Where there is a will, there is way.

The bushing and the thrust bearing seem to be in very good shape. I just need to find some new seals. Hope those aren't too hard to find.

Thanks again.
