Willy Posted April 18, 2011 Posted April 18, 2011 Have you ever tried to put 10lb's of sssstuff in a 5lb bag?? That is kind of like stuffing 16hp Eng. in a 10 horse tractor. I started my Eng swap but it isn't going like I hoped it would. The shroud don't sit down inside the frame and I don't want to butcher the tractor so I think I'll butcher the shroud. I think I can cut a slot in each side so it will settle in. I will have to drill new holes to mount it. I pulled the head and pan off the 10 horse to see how bad it was,it didn't get the gov or the piston or cyl wall. Can't say the same about the crank,I'll take it in and see how much will have to come off to clean it up. There is allot if the rod stuck to it. I tried cleaning it up some with emery cloth but it stuck tight and the machine shop can do it allot easier.
ReedS Posted April 18, 2011 Posted April 18, 2011 The 16hp briggs single should be a direct swap, no butchery needed, unless your trying to put it into a b-1 or an early 700. I've both done it and seen it done! On both the b-1 and 700/725 you'll need the cut the trapezoidal hole in the frame for the engine to sit into the frame, the 16 should also be able to use the original oil pan as well! The 16 is a big improvement over the 10!
Willy Posted April 18, 2011 Author Posted April 18, 2011 This is a twin cyl 16 hp.a little different configuration. A single would be allot easier. If it get to the place that I have to cut the frame I'll just rebuild the 10 horse and put the 16 in something I don't care if the frame needs cut.
bud119195 Posted April 18, 2011 Posted April 18, 2011 Simpletom put a 16 in his 725 and all He did is notch a little out of the shroud
stangman1 Posted April 19, 2011 Posted April 19, 2011 If you want to use a twin, why not put spacers under it and put u-joints in the driveshaft?

Still, little modifications to do that job.
TomSchmit Posted April 19, 2011 Posted April 19, 2011 Willie - I looked at putting a 16 twin into a B-10, and came to the same conclusion that cutting the shrouds would let the engine settle into the proper position. As I recall, it needed to be raised up a little bit in order to put the driveshaft in its proper (ie original) position. I never went thru with the swap but I think you can make it work without cutting the frame! Tom
Doll Posted April 19, 2011 Posted April 19, 2011 Many times the aluminum from the rod will stick to the iron of the crank journel and not damage the iron. If you take the crank to an engine machine shop with a block "cooker" the acid in the cooker will disolve the aluminum and won't hurt the iron. You can do this yourself with muriatic acid. It don't bother my skin (but have heard it bothers some people) so I just wet a paper towel and brush it on. Works great to remove aluminum from a piston in a steel or iron sleeve too. Don't breath the fumes and flush the metal you used this stuff on with lots of water then dry and coat with oil or it will rust big time.
Willy Posted April 19, 2011 Author Posted April 19, 2011 I have a Big 10 I'm not so fussy with I think I'll put the Twin 16 in it and rebuild the 10 horse. Still thinking on it.
BLT Posted April 19, 2011 Posted April 19, 2011 The 16 twin crankshaft centerline is .44" higher then the 10 HP. I took the dimensions off the standard footprin dimensions I have.

I took the dimensions off the standard footprin dimensions I have. Now I remember you posting that info earlier but my CRS is a problem once in a while. I think that would be asking to much of the flex couplers. I think I'll look for a single cyl 16 or rebuild the 10 and be happy with that. Thanks for the reminder.
