Speed up a 77

matthies · Jul 5, 2018

Guy said that I need to move a couple gears from shaft to shaft. While I have the engine/clutch out and the input shaft splines are shot, seems like it would be the time to go forth. FIL has been getting standard gears to put in his rowcrops, but rumor has it that you can just move some gears around in the trans. Any help would be good. thanks chris

I sent you an e-mail. You are not going to move them from shaft to shaft! How fast do you want to go? How about a serial number to see which ring and pinion gears you have.

Didn't think it was possible, but the customer is always right!!

14-16 for tractor rides is what he wants I'm sure. Will get a serial number for you.

He should just put a set of 42's on it. Like having summer and snow tires.

Just talked with the FIL a bit and you turn the sliding gear on the input shaft around, then take the middle two gears on the countershaft and exchange them with the outside(on the end of shaft) two gears. Play flip flop. he had a standard trans and a rowcrop trans side by side and that's the difference, yes you can change ring/pinion out, but this way there is no iron to buy. So I will get the trans opened up by next week I hope. I don't know the length of my input shaft yet, but are the A&I shafts any good? Agco, used? thanks chris
