I was made aware that there were two V4 Uni-Harvestor engines MM built. One 445 type engine one ZA style engine. I have yet to see one other than pictures. I hear they sound neat. Do they have a bell housing? Would they go in a tractor? I would like to find some. Just curious. I have the I-4 but would love to see a V-4.

The reason they sound neat is they have 'odd fire'. they crank rotates over 200 degrees between firing #1 and the next cylinder. Then the following 2 cylinders fire in rapid succession. Then another big gap to get back to #1. The breaker point cam in the distribuitor is special and you have to have that special tang on the rotor button in order to distribuite the fire to the lugs in the dist. cap.
These engines do not have a bell housing. The flywheel is exposed and is integral with the variable speed pulley for the ground drive. The opposite end of the crank has a flat pulley to power the implement. These engines would not go in a tractor without some serious modification. Also, I may be mistaken but I think they turn backwards.

A few other little neat things: 2 camshafts,one for each cylinder block. one drives the governor and the other drives the distribuitor. The oil pump is made like an automatic transmission pump and more or less floats on the crankshaft.

I have a friend that owns several of the units with a variety of engines including the V-4. Contact me for information.

Very interesting. I like the sound of the Honda V4 bike motors. I figured that was why it sounded like that. Like a V8 has a slight lope too. Thanks for the details. It would be great in a tractor if one could do it. Maybe easier to put it in one with a drive shaft like an Avery, Oliver, or Massey Harris. Maybe even neat to build a V8 out of two. Sounds like a very special motor for just that application. Were they used as stationary units?

I've never heard of any used for a stationary application. I always wanted to put one in an R but it would take lots of work and never look right. It would be a neet engine in an Avery. If you did a professional job you could fool people like me who don't know anything about them into thinking it was right.

Yes. Can you imagine an Avery model V with a 206 V4? I think it would break something eventually. Some folks would not notice in maybe a BF. It would be a great exibition piece! Sounds like a lot of work. A BF would be easier. Money and time, money and time my friend. MM makes the most interesting things. I always thought a diesel R or J would turn heads(Jet Star diesel motor). Or even a diesel in an MTA or KTA. Maybe an R with a 335 tranny and ampli-torque. Interchangability can cause some neat combos with tractor people.
