Quad engines?

[Littlebow01]

Has anyone explored the prospect of swaping in an engine from a quad into an aatv?

[superdave]

Maybe a two-stroke from a mid-90's Polaris 4-wheeler, otherwise probably not practical with the integral manual shift transmission in a typical ATV engine. Although I did see a picture of a 4 cylinder Ford engine stuffed in a Max, so I suppose anything is possible....................

I have heard of people saying they are going to but never seen it done. I think all the shifting would be a hassle.

[superdave]

The more I think about it..........if the intent was to eliminate the stock transmission, then how would you turn? By adding a brake system somehow, I guess?

I suppose I am thinking from an Attex perspective, which I would never even think of putting in a quad or motorcycle engine. I can't even think of one advantage. However, other AATV's use several different types of drive and steering systems which may make things a bit easier, and worth the effort. Maybe.

Littlebow01, what type of machine do you have? What type of quad engine?

Imagine trying to clutch, shift, throttle, and steer at the same time with two sticks? Whew,thats a handful!

many of today's quads have variable transmissions !!!!!! if you can match the clutching why not ? i think a big v-twin quad engine would work great!!

superdave hows the project coming??

I dont know the model but I rode a polaris with a v-twin variable speed trans. It was I think a 650 and hauled. Not sure if it was air cooled or not. Seems like it was liquid but dont remember a radiator. But these motor are probably not cheap as there are new and not laying around for 20 years waiting for such a project.

i know what you mean!!!! i've been looking for a big sled engine for my racer and there isn't much in my price range (cheep) lol but if money was no object and you wanted something unique a big utility quad engine would be cool

There was one for sale over here in the uk with a citreon 2cv car engine in an argo 8x8, they claimed it would do 60 mph.......dint like the sound of that!!

[Littlebow01]

I wasn't thinking of the speed but getting a nice quiet 4 stroke. If you used the stock tranny from a quad and put it in its 1:1 gear do you think that might work to drive the aatv trans? Or if you had a newer quad engine that has an automatic trans could you have it drive the aatv trans.

[Littlebow01]

Oh I am working a deal to get an early 80`s argo 8x8 with no engine, but the guy bougth all new bearings,seals etc.. tires too i think. He tore it down to rebuild it and has changed jobs and has no time to finish or use the argo, so in a couple of weeks I will go and pick it up for $500. I`ll have to put it together and put a motor in it.

[Jeff t-boss]

*x* argo for $500.00. That is a SWEET deal.

I know that some of the utv's use a cvt clutch like we do on amphibs.Two that come to mind are the Kawasaki Mule and the Yahaha Rhino.Not sure what the cost of one of these engines would be.If they are more expensive than the "lawnmower" engines we use now,the added cost and work to mount them would render the point moot.But If a guy had one laying around,it might be fun to play with just to see if it would work.If I had one and it could be done without MAJOR alteration to the mounts I know I would try.But it would probably be best to try the Mule - Rhino type powerplant for simplicity.So there's my nickel's worth.

[Littlebow01]

On the quads they have a cvt that drives a chain to the axle, what about having a chain drive the aatv trans instead of a belt.
