I posted a message about repowering a 140 with a bigger engine. Someone suggested a 20hp twin ohv Kohler, but no engine # or if fab work would have to be done. If anyone knows or has plans...
please send me a note or link.

THANKS

Hey Bennie,

I'll measure the shaft and motor mounts tomorrow. I'm sure they are the same on my 20 H.P. Twin as my 14 H.P. Somebody is blowing smoke up your rear on the H.P./ Hydro issue. You can put 300 H.P. in front of it as long as your turning the same RPM as your 14 H.P. I turn mine 3800-4000.

Rob

I repowered a 140 with a Briggs Vangard V-twin, 18hp. Have beat the dickens out of it for several years. No problems yet. I have a complete write-up of the change-over. Send me an email at cttrprch@pathwaynet.com - I'll fire off a copy.

The Kohler 14 hp is a good solid engine that's fairly easy and cheap to rebuild. If you're dead set on a repower, can I buy your Kohler cheap?

why not just rebuild your original engine? You'll tear the hydro out of it putting that much horsepower through it! It was made 14 HP for a REASON

Small engine warehouse has a listing on ebay for a 14 hp v twin Briggs repower. The kit comes with all instructions and needed bracketing. Go to ebay and select 140 John Deere and scroll down.The kit is around $1300 delivered.
I have seen a couple of 140's backyard repowered with larger engines(16-20 hp) but they require alot of modification,and don't look at all well designed when completed with the hoods cut,frames notched,electric clutch rigged on etc.
