engine swap?
 

Need your advise on my idea for an engine swap before I potentially open one big can of worms:Huh:
I'm starting my next project, it's a 1610 with a oil leaking, rough running twin Briggs. I have a good twin Kohler in a 1720. Will it fit without much modification? I'm not afraid of somethings needing to be done, but before I pull the Kohler and go through the work of cleaning and painting and it won't fit, well you know the rest of the story.
Just wondering if someone would know the answer to my question.
Thanks

I don't see why not...they're basically the same tractor with a different engine.

I thought so to, but I put them side by side and the frames are different, from the sides ayway. One also has the battery up front, one out back, not that that should make a bit of difference thou.
One's an 86, the other (1720) I think is an 89? the one I'm going to build is the 1610 (86) and it has the hydro on the fender, the other is the dash, the 1610 is also 1 1/2 iches taller, so I think the frame is different all together.
Does any of this matter? I don't know. Just wanted to know if any one has had experienced an engine swap from briggs to kohler without alot of trouble.
Thanks

Engine swaps themselves are not bad. The more time consuming thing is the wire harness. Big not is, it may change the location of your pully slightly, making need of a different drive belt and or pto belt if thats the style set up you have. I know this is sacralige, but I just pulled a 16 HP OHV power plus briggs from a hydro wheelhorse with blown tranny and put it on one of my cubs. I pulled the entire wire harness and put the one from the wheel horse on it. I had to change the throttle cable with one from my hydro parts cub to work. Took me about 6 hours. Issue now is the belt! LOL.
