DMedal Posted July 26, 2008 Posted July 26, 2008 now that I have a running M18 Kohler (thanks, guys!) I realize this isn't going to be a drop in for my 710, *maybe* into the 2210. It is supposed to blow oil but hasn't yet for me, maybe I haven't run it long enough. What AC/Simples does the M18 fit, if any? thanks! -Don
Chris727 Posted July 26, 2008 Posted July 26, 2008 A magnum 18 is a twin isn't it? IF its a twin, then it might fit in a 7100 Simplicity, 900 Allis or Sunstar which originally had a twin, though they made different pansfor various brands of tractors.
DMedal Posted July 27, 2008 Author Posted July 27, 2008 yes, it is a twin, horizontally opposed like an Onan. Shaft height is perfect, I think it woul just drop in, but the cylinders make it too wide, too low, to clear the frame. I assume this would be a problem with any opposed twin. I bet it would fit a Powrmax, but I don't have one.:( It seems to be a strong engine, and I got it w/out starter or carb for $49! Altogether I've got less than $150 into it. I'm not going to run it anymore until it is bolted to something more solid than a small sheet of plywood. I opened the throttle up quickly a couple of nights ago and it nearly flipped upside down due to torque reaction. :O :D
GregB Posted July 27, 2008 Posted July 27, 2008 Will drop-in fit a 7117 or a 917 AC. you may need to extend the cut out of the frame to clear an oil filter if it has one. Worked for me. I have seen someone modify the frame, cut it down to clear the motor. That is what they did from the factory. Find someone with a twin in it, measure or make a template, get busy with the sawsall. :D GregB
DMedal Posted July 27, 2008 Author Posted July 27, 2008 quote:Originally posted by GregB Will drop-in fit a 7117 or a 917 AC. Is 910 th same tractor without the cutouts? I have one w/out an engine. I was a little shy about that much cutting but I think you just enabled me. :D -Don
ambler Posted July 27, 2008 Posted July 27, 2008 Yes the single cylinder models need the frame cuts in 900 or 7100 series, but the frame is long enough for the twin.
DMedal Posted July 27, 2008 Author Posted July 27, 2008 Did I say 910? 710! I must have had a brain problem for a bit there. 710 is what I have. Geez. Your brain probably never runs rough. But 710 is roughly like a 7000 series, isn't it? And the frame on those is shorter? I guess I need more tractors to figure this all out.
ambler Posted July 27, 2008 Posted July 27, 2008 Yep, 710 is too short for the magnum. 900, 7100s are longer in the frame.
DMedal Posted July 28, 2008 Author Posted July 28, 2008 sounds like the 2210 chassis has a date with the sawzall and welder. Thanks for the tips. Maybe the 710 gets a Briggs 10 after all. It will be weak for rototilling, yes?
MikeES Posted July 28, 2008 Posted July 28, 2008 Don, the 10hp will work fine rototilling. Especially with the 6-speed. I have a 710H works great on the tiller and revitalizer. BTW to fit the KT17-M19-KT91-M20 twins in a 7100 or 900 series frame that originally had a single, you need to cut an 1-1/4" out from ea. side frame. Thats it everything else fits. The engine pan already contains the correct mounting holes. I have done this a couple of times.
DMedal Posted July 29, 2008 Author Posted July 29, 2008 thanks, Mike. Now I just have to get a 7100/900 and I'm all set! Family says I have enough tractors for a while. :D
quantico Posted July 30, 2008 Posted July 30, 2008 I have M18's in several sunstars and currently am trying to fix one that was a re-power for a 917 allis... the m18 is a very well made engine and has many varients based on crank output size...
