According to the service manual, the grain tank has to come off in order to pull the clean grain elevator. That’s a tall order. In my case, we are talking about the 25 bushel “Big Bin”. If it is anything like the 17 bushel version on the 60’s/early 66, getting the tank back on is even harder than taking off. So on this 66 I am repairing I thought I would try to take it off with the tank still on. Granted, the tank has to come off anyway, so I was not doing myself any favors, but thought this would be an educational experience.
Sure enough, after detaching the elevator, there didn’t seem to be a way to pull it out. It then occurred to me that perhaps I could pull it out from underneath the combine. I took off the highlighted parts shown below, raised up the wheel under the tank and pulled it out from behind the combine.
One word of caution. When lifting the wheel, your left side front of the header will take a dive into the ground, so you may have to lift up the other wheel as well. I have a gravel floor so I was able to gain a couple inches clearance by digging into the floor so the header was not unduly stressed.
