Y, it's a 100 pump. I bought this pump from a local salvage yard, he had about 6 or so of these and I intentionally picked the one NOT from the combine because I didn't need a shutoff solenoid....HA. It's not like I bought it sight unseen either, I had the stupid thing in my hands and didn't notice that it didn't have a kill lever, then to top it off I took it to the pump shop and had it completely rebuilt. Feeling like a real genius here.
Go back to the salvage yard and get the other pump to get the shutoff solenoid you say. I agree, the salvage yard gets $300 per pump. Well, funny thing about that, the guy went out of business on Oct 31st, and everything went into the scrap bins. I got there the day after they had cleaned the fuel pump shelves.....You want to see a grown man cry, I did that day. I managed to save a couple of hydraulic pumps, 3 hydraulic remote valves, and 2 steering cylinders for a 2-150 (yes I did dumpster dive and no I'm not ashamed of it), but alas none of those are helpful here.
The $900 you quoted is funny too, because it's the number I found out yesterday when I came to the conclusion that we'd have to set this thing up with the solenoid to make it work, and then priced one. But that's also the number that the radiator shop quoted me yesterday to re-core the radiator. His words "man, this is a really big radiator with a lot of fins per inch, are you sitting down". Never what you want to hear from him. $900 is how much I paid for the new surplus Herc that we're transplanting into this thing, and also the amount I spent on the 2 stage clutch.
If you're keeping count, yes this winter project is already getting expensive. But on the positive side, my 2nd crop beans did make 12 bushel/acre this year, which is 10 more than last year. The wife is VERY excited about the yield trend.....I'm not letting her in on the joke until after the winter project is finished!
