I'm Repowering my open side lgt 165. This tractor is not original and the engine is gone, so I don't mind modifying it a bit. I got it in trade for a lgt 145 with no engine and crappy steel. It hade a rear pto, and bad steering. The rubber was crap too.

The only engine I have handy right now is a GX390 13hp Honda clone. I'm waiting for a 15 hp version to come on sale at Princess Auto,but for now this will do.

I'll need to adapt the 3 bolt Honda flywheel pattern to the 4 bolt Kohler pattern.

Other than that it should be pretty straight forward.

Can't use a stock pto with this engine configuration, but I intend to run accessories off the output shaft.

And I could run a pto down the other side with a few mods. if the need comes up.

Where did the grill come from? Doen't look like any of mine. Good Luck, Rick

[Chopperhed]

The grill is a nice custom aluminum piece that came on the tractor. Since this tractor will end up being my dozer build, I'm just going to paint it.

Got some work done

Built the flywheel adapter the hard way, careful measurement, 3 times, careful layout on a block of 3/4" x 4"x4" steel plate. Done with heavy duty drill press, band saw, and hole saw. when I get my metric bolts in, I'll line up the adapter and driveshaft with a dial indicator to get it as close as I can.

Also cut a hole in the center of the recoil cover to act as a bit of a guard.
The stock drivehaft guard will cover the rest, so it should be safe.

Then of course, I had to mock it up with the sheet metal to see how it will look.

checked out clearance on the stock fuel tank, and will be tons of room with an easy to make bracket. there will be tons of room for engine accessories, like an alternator, and or, pto. Looks like it will line up with the mule drive too.

I had to build a motor mount plate to fit the Honda clone engine mounts, and space the engine up a bit.

Actually on closer inspection, it's stainless, and needs to be adjusted a bit for better alignment with the hood.



Soon as I get the stack welded up, and a fuel tank in, I'll be able to fire it up. Making the muffler out of 1" and 2" conduit. I know the holes are crooked, but the will never be seen again after it is welded/or brazed, whichever I decide to do. The threads you see I the 1" section is a 3/8 Carriage bolt, I hammered down the bore to act as a barrier to force gases through the 2" section.

Got the engine and bolted down. all the driveline is bolted in, and I mocked up the guard to check clearances. I've got two options for an air filter, can't decide which way to go.

I can do a straight vertical up the same side as the muffler, or cross over above the guard and under the hood to hang out the other side and balance the look

Decisions decisions...

Wow, nice looking retrofit.
I assume the metric bolts came in and all went as planned there.

As for the air cleaner, can you make one that looks like your exhaust and run them both up the left?

[skyrydr2]

If that emt is galvanized be very careful welding or brazing it !! The fumes can make you some sick!!

 Its lookin good so far!!

I have plenty of experience with galvinized. Got my milk and ventilation ready

its a runner, here's the vid

I made an important discovery regarding these Honda clones.

The mods I made to the air filter and exhaust make it run lean.

I'll have to add a baffle to the exhaust, and choke the air filter.

I found that the only way I can get it to run at higher rpm is to tape off half of the air filter and it still hunts a bit. I may have to drill out the main jet a size or two.

I think your re-jetting carb is a good idea. Go easy on enlarging the hole. 

Looks like your making good headway.

[Chopperhed]

I have a pin vice, the drills go down to a few thousands of an inch. It will require several tries to get it right, but its not difficult, just time consuming.

You got that right but it sure is worth the effort.
