I am looking into doing a repower on my 140 H3. There are many choices from what I am seeing. So help me folks, who has done one and what engine should I go with? Pics would be nice also. Thanks.

I remember years ago there was a great thread on here about a 140 re-power. They used a Vanguard engine and covered the whole process. That thread may have been lost when the forum moved from the old site to this one, but it would be worthwhile to do a search for it.

I repowered one of my 140 with a Kohler K 341 (16 hp) out of a JD216. I rebuilt the engine with "I Save Tractor" parts and NAPA did the machine work. Less than $400 invested (including what I paid for the engine) and it was a bolt in swap.

There are two places I know of that has repower kits.

Jim's Tractor
He has some info on his kits

Small Engine Warehouse

If you know a machinist that would make the parts for you, then just buy a new engine and have the parts made.

I've been thinking about buying a 22 hp HF Predator engine for a 314 swap. I've had very good luck with 3 that HF Predator engines I have. I had one for 5 or 6 years now on a go kart with no governor. If you go with a Predator, you'll need to get a Honda stator and change it out. The Predator only had a 3 or 5 amp stator and will not charge enough to keep up with the PTO.

The kohler engine is hard to beat

I would rebuild current one or get a K341

Mine have survived 50 years of abuse.

I agree 100%. And it will still retain it's resale value. There is a Honda repowered 317 for $350 on Springfield Mo C/L that has been there for over 2 months. I just don't think some people like to buy something like a garden tractor that has been changed because if they have problems, who do they turn to for info on the swap.

Yea I could do a rebuild. I was just looking an a little more Hp and Torque.
The Kohler 16 hp K341 is a beast. It's like 15% more power than the K321, and I can tell the difference. And in today's HP comparisons, I guessing that it would be around 20Hp. The guy that lives a couple houses down the road has a 24hp briggs powered Husqvarna that was down for a month last year. I let him use my 16 hp 140 and after using it, he said that it felt like it had almost as much power that his big V twin Briggs.

I bought a junk 216 for $200, and took the engine off and sold the rest for $130. I wouldn't pay more than $150 for one that will need rebuilt. If you can find one that is good shape (uses no oil and no funny sounds from it), I would go as high as $400.

You might find a good running 216, 316 K, or 300 and pull the engine and part out or sell the rest. If your 140 is a late one, the Hydro parts will interchange with 316 and 300. I know that 1650 cub cadet engine will fit too.

I retro-fitted one of my 140-H3's maybe five years ago now with a Vanguard 16hp twin I'm very happy with the results! Its quieter, runs smoother, more power and fuel efficient too! No modifications to the tractor are required as I recall. I used an driveshaft/hub adapter, wiring harness and muffler provided by Small Engine Warehouse.

I would try to go Kohler K series. If you want to go more modern I would go briggs Vanguard. I have a buddy that repowered his 318 with a 16HP vanguard and says he can't tell the difference. I think Kohlers(K series/Magnum) were better than briggs. I think biggs vanguard is better than Kohler Command. Just my opinion. I am getting close to tackling an H3 project myself.

I am now looking into repower engines for 140 H3 to replace an old and tired K341. I am in process of buying the tractor so kind of early to tell if original engine is rebuild-able but I would like to try a twin cylinder Vanguard. Looking at repower from Smallenginewarehouse it looks like the air cleaner is cut in half leaving the air filter exposed to get clearance for fuel tank. Is this true? Looks like a butcher job to me. Extremely undesirable to me. Wouldn't it be better to relocate fuel tank under fender deck?

Is there a Honda kit available from someone?

Absolutely no Predator engines for me!

nkaust, The quick answer is maybe! It ALL depends on the idle speed. I think there's a big difference in what most people think "idle" should sound like and what Kohler spec's out. 2000-2200 rpm is the Kohler spec for the K321 and 2100 for the K341. At this rpm, it just "sounds" too fast, but that's the spec.

Not sure what my idle was on my 314, but it "sounded" right...except for the hood, pedestal and everything else clanking and vibrating around! I brought the idle up to around 2000 rpm and everything smoothed right out! It's amazing what you can learn by reading a manual! Bob

Gabby, I seem to remember a re-power thread years ago where an offset air cleaner adapter was made so the Briggs air cleaner didn't have to be cut to clear the gas tank. I've also had the thought that maybe a thinner battery could be used so the gas tank could be situated further back to enable air cleaner clearance.

The other option (I have not researched yet) is an under fender deck fuel tank. I would really like to go the Vanguard route but will not run around with an exposed air filter. I can't believe that is offered as a solution to make it fit. Was the relocated air cleaner article on WFM?

do the engines in the 140 vibrate like the 300's and 316k's
No the K321 is bolted to the frame and not on isolators like the 300 series. It shakes, it's suppressed by the frame.

Gabby, rebuild if the cylinder wall is still good.

Drew, buying a load of Deere machines from a member in western Michigan. He says the engine in the 140 ran when parked but extremely tired so it should be rebuildable. I was just looking at building up a real work horse with twin cylinders. You are correct I probably need to stick to the Kohler engine. I was really disappointed when I saw what supplier was doing to the air cleaner on the Vanguard to make it fit. Will post photos of future projects when I get them home. Happy Thanksgiving Drew.
