782 Repower Opinions

Recommended Posts

The Series 1 KT-17 mosquito fogger in my 782 finally gave up the ghost a few years back.

Looks like I might finally have the time and funds available to get the old girl going again so 

I wondered what other forum members have done in this situation.  Thanks in advance,

Really depends on your mechanical skill level and what you have available as an organ donor.

I did a Command 18 swap on one of my 782s and I'm happy with it.  My other 782 needs an engine and I haven't decided yet what I'm going to do on that one.

I think I outlined my Command swap on another thread here a year or two ago.

Is a Kohler Command or Magnum almost a direct swap? Are new suitable Kohlers available? Is there a kit for a Honda or B&S or such?

Here is what I know, or have been told, so far.  Direct swaps either do not exist or are very rare ($$$$).  Series I Kt-17's aren't worth the effort or expense to rebuild.

At least one small engine supplier offers a repower kit that uses a B&S Vanguard twin.  I'm a little leery of this due to some unfavorable experiences with B&S engines.

In my mind this leaves Kohler and Honda.  CCC used the Command twins in subsequent Cub Cadet model s (18XX series IIRC) so I was leaning that way BUT I am finding that most of the parts to allow a direct drop in are NLA.

I have exactly zero experience with Honda small engines except the knowledge that, hey they're Honda's.  So that's why I decided to ask the question.  If I can learn from other's experience and save myself some aggravation then why not.

Thanks for the input.  While I'm no master craftsman, I have the ability to do basic fabrication, assembly, and wiring.  Time and money have been my limiting factors.  Now I get to show my ignorance.  How can I search to find your swap thread?

Well, let's see...Northern Tool sells Commands....Magnum doesn't seem to be in production....Repower Specialists does two Hondas and a Kohler Command.

Yeah, Commands are not too difficult to get. A local small engine shop I like to deal with used to keep them on the shelf.  They finally dropped them when they couldn't compete with internet prices.  I am not acquainted with Repower Specialists, I'll have to check them out.

Jim's Repair likes B&S Vanguard. So does Small Engine Warehouse.

If the Vanguard is a quality engine then I have no problem with it, just no experience.  B&S experience is limited to their small single cylinders.  Most I've had seemed to be 3-5 year throw away designs.  Not what I'm looking for here.

Look for the thread 'Kohler Command 18S' by Ronknee, I think it was on page 3, I posted there and gave a rough outline.

The Command isn't hard to do but took me about 2 months (my Dad passed away in the same timeframe so that took some of my time too).  

I sourced my engine and the exhaust system (1863/4) from a guy semi-local here at the time.  I didn't rebuild the engine.  The tractor is my tiller/snowthrower/back up mower and has been great since the swap.

Really the hardest part was sorting out the wiring.

A used 18hp Magnum is drop in except for simple ignition wiring.  Command is a little more work but not bad.

As others have said, B&S and Honda kits out there too.

My 782 that I bought last summer had a magnum 18 that had been rebuilt and put in it. Starts right up and runs nice. Saw a 982 recently with a command 20 transplanted into it. Dont know what it took to do either but both would make nice engines I would think. 

     On another note what are any of these engines worth now a days to buy/ sell?

Bought an M15 (detuned M18) in a roller chassis for $150.....this spring.....just for the spare engine.

Interesting....I bought an 1862 that came with a 1541 maybe? Parts tractor. Whatever model it is it's a 15 hp. The 1862 I'm 99% certain has a blown head gasket. Was contemplating swaping

the 15 into it at least temporarily. Intent was to set up a snow blower with ps for over at moms. Tired of raking gravel out of the front yard after blading snow with the kubota and blade all winter.

    So what is different between the 15 and 18?

    I asked what they were worth as I saw a command 20hp iirc advertised for around 900 which I found pretty pricey. Maybe it was a misprint?

Also saw a 3205 With a kawasaki engine in it. Would those be a nice engine for transplanting into anything or too much trouble or not a desirable engine?

Swap carbs from M18 onto M15, set her at 3600rpm and let her eat!!!!

Remember M series use grounding kill switch, KT series are power to coil switch......MUST rewire ignition circuit/ switch or install relay to make that swap or you will kill magneto ignition module and be pulling engine again to replace.

Kaw is a solid motor.....I have an 18hp liquid Kawasaki vertical shaft on my 365L ZTR, 500 hours and has been a solid and strong motor so far....

KT 17 carb could also be swapped onto M15....

1541 was the cyclops M15 tractor.

I replaced the Kohler in my 782 with a 18hp Honda V twin about 15 years ago.    Got it from small engine warehouse and it works great.

You have to be careful you don't get stuck with a poorly engineered swap or poor customer service, though.

They must have changed     When I did the swap everything fit like a glove, the instructions were informative.   I did not have to try customer service.

Vanguards are a good engine.  Intek and other stuff they sell is lesser quality.  The V twin Vanguards have Japanese involvement in the form of Daihatsu/Toyota/Mitsubishi.
