16 hp in 147 frame

[sawdustdad]

I think the situation is this. The narrow frame will accept a K series up to 12hp. Over that, 14 or 16 hp, the frame is too narrow to accommodate the larger flywheel and shroud used on 14/16hp engines.. The 147/149 had the frame notched to accommodate the larger shroud.

If you take the flywheel and shroud from a 12hp engine and put it on the 14 or 16 hp, it would fit the NF without a notch.

I would not be concerned about cooling while blowing snow. (assuming it's naturally occurring snow, meaning ambient temps are chilly.) But cutting heavy grass in the summer might overtax the cooling capability of the smaller flywheel.

For what it's worth I stuck a Mag 12 in a 71 frame. Had to cut the frame to clear but it came out pretty decent. Probably wouldn't do it again but it was fun.

It did not work well for Dad when he tried it either.

Either way (despite it was set for pulling) I think that is the bees knees! Big 16hp bigblock in a narrow frame with a manual tranny!

So you have a 166 huh?

Yes, everyone here nailed it. The fan, shroud and rear plate for the 10/12 motors are smaller. I've got a 16 at the shop now for a member here who stuffed it in a NF with the smaller fan. Like Don said in post #4, it's tight but it will fit.

The 16 HP block is a little larger than the others.

As far as cooling...... like I said, depending on what you are doing with it whether I would use a 16 with the small fan. If you plan on really working the crap out of it, I wouldn't. Go with the 14, or notch the frame so you can use the bigger fan. I agree with using the non-ring gear style and going with a S/G instead of the gear starter. Saves room, keeps it looking more original and is less work.

[Userj8670]

Can you have a 16 with a ring gear swapped over to run with a starter/gen? What all is involved. I assume one could use the tins from a wheel horse k341?

[J-Mech]

All the cranks are the same size on the flywheel end. But the other end varies between the different applications. Are you trying to use a WH motor? Cause.... they have the large base block don't they? Pretty sure all WH's used the big base. Tin-work should be the same. Don't think that was different.

The rubber mounted Wheel Horse K Series used the narrow base engines.

Thats correct Jon. All wheel Horses used the bigger sump (with the mounting ears coming out). All of them were also mounted perpendicular to the frame instead of parallel like internationals.
