Get a piece of water pipe to extend the breaker bar, also helps to tie down the yoke, I use a 48” pipe wrench for that.

Diesel repair shops have what is called a "torque multiplier" which fits on a breaker bar where the socket goes. A 100#'s on the handle gives 200#'s at the socket or they make them where a 100#'s at the handle gives 400#'s at the socket. A bit pricey for one time use but Home Depot sells them so their tool rental probably rents them.

The shop I ran when in the Army had a torque multiplier for working on tanks. It looked like it took two guys to carry it. One of those probably isn't needed for this project.

Ed hit the nail on the head when he recommended using something to hold on to the yoke. I have used a flat bar drilled for the yoke bolts and with a hole for the socket to clear. That and a cheater on the breaker bar should do the trick.

The flat bar works well. I drilled a piece of leaf spring and use it to react the torque to the ground or to the frame. Also be certain that the cotter pin has been completely removed. They rust over time and it can be hard to get all of the pin out in one piece. You may even be able to get the socket over the nut with remnants of the old cotter pin still in place and not notice it.

I broke out my 3/4" air gun for it's first use and it wasn't up to the job. I went to the local rentall and they said they didn't have a 3/4" air gun. On the way out I thought, I wonder if they have a 3/4" electric. It turns out they did and it worked fine. I eventually got my 3/4" air tool working. It turns out that the oil inside from the factory did not work well after sitting in a cold garage!
