1984 ezgo marathon engine replacement to atv engine

[ruredy]

my guess is it'll be pretty close to what the honda was,(shaft drive, right) not sure of that cart's rear ratio, newer ones are 13 to 1. I would say that's pretty close to what the honda had. If you had the rear out of the honda you could mark, rotate, and count the ratio, or divide the theeth count to get it. same with the cart's rear. maybe it's ratio is listed by honda somewhere. knowing that then it's just the tire size difference if there the same or close to it.

That is looking awesome.

Well the Honda rancher rear end ratio is 3.769. That is right out of my Honda service manual. The atv went around 50 mph top speed with 24 inch tires. So you will have to do some figuring. Anyhow the engine is going to haul. I'm using that same engine and all the running gear,suspension and all. Pretty much stretched the atv frame and set the cart frame on top. Should be fun with 4x4 and everything. Hope you get it all figured out.

little bit at a time!!!!!!!! The one pic is the honda u joint adapted to the golf cart rear spline piece...we ended up ruining a perfectly good drive clutch...LOL...drilled a 3/8" hole thru both pieces and then spot welded the center completely then run a weld completely around the whole shaft....

The cart is looking real good. I am converting an electric 3 wheel cart to gas for a guy, (86 model) and have an engine out of an 85 4 wheel cart, but I don't have the starter, or any of the brackets for it. Would you be interested in selling any parts you wont use? Will Post pics, in another thread, dont want to hijack yours.
Thanks Earl

sorry guys the cart is done will post more pics but im in sum need of help ...when we put the engine in 1st gear it actually started turning the wheels in reverse so we took the rear axle and differential apart and flipped it so now it goes forward when in first but the thing is now with the 12.25:1 ratio on the model 12 rear end im only getting 15mph top speed ....this model axle/differential came with a 5.17:1 ratio also I NEED THEM BAD ring and pinion...dana part number on this is 825156X can someone help me locate it

[ruredy]

I might have one of those rear ends, I just went to look at it and realized it's upside down from the pics I had looked on the dana site so I didn't recognize it right off. I know it uses ezgo hubs (there a few different brand carts that use the same) anyway, I had counted the ratio once before by turning the pinion with the tire marked and I was thinking it was near a 6 to 1. it was not a very accurate way of checking, more so I'd have a guestamation of what it was.
it had some numbers on the center section 8535-18-x1 kinda leads me to believe it may just be a model 18 rear. I can check it out tomorrow when there's some light and try and figure it out for sure.
