Onlly Have The engine....

[lyndong4]

Okay, Ive Got A 6.5 hp tecumseh engine,(a friend of mine let me have it) and nothing else.... i am decent at welding, so the frame is not a problem. I just need help with, well, everything else. the main thing for me is what gear ratio to use, its going to be an offroad cart, but i still wana kick the back end out on pavement and the dirt.

ps ps what is a jackshaft and do i need one?

 

[THE HUNTER]

its that shaft in the middle of the pic

and if you are building the frame yourself, you shouldnt need one.

its going to be an offroad cart, but i still wana kick the back end out on pavement and the dirt.

Very low ratio then, and skinny tyres. I'd go with a 7:1, or 6.5:1.

thanx guys

Yeah Id go with a 9t engine sprocket and 60t axle. And maybe if you want to put some money into the engine get batman's hop up kit. Along with a 30 series torque converter that'll give you some more power break the tires loose. And maybe instead of getting knobby tires get some turf savers. I like to slide around too, So I purposely let my knobby tires go until theyre about bald. After that Im getting some turf savers. Have fun drivin' that thing sideways! lol And also, with such a high gear ratio you're not going to have very much top speed. You can take the gov off the engine but I wouldnt rev a stock tec passed like 4200rpm.

I wouldnt rev a stock tec passed like 4200rpm.

I run mine past 5,500 rpm regularly.

 

[Kaptain Krunch]

4200rpm is barely past stock...Now dont get me wrong i wouldnt go holding it at 5k for a too long.

 

[Affair_driven]

It's held up for at least 5 summers now.

 

[Kaptain Krunch]

It's held up for at least 5 summers now.

No i mean like constantly holding it WOT at 5k, that would probably end with a broken rod.

 

[lyndong4]

what size tires? and turf saver seems a lilttle to pansy for offroading, maybe packed dirt, but i mean some pretty rough trails, like 6/10 for a kart and another thing, on the comet 30 the drive is keyed also, so how do i hook that up to just a bar stock live axle??

 

[lyndong4]

oh crap... i need a jackshaft for the converter?

 

[mike75925]

depends on which one you get the tav2 has a jackshaft already

 

[lyndong4]

okay guys good news.... got the frame, me and my uncle got the thing built in 3 days now i need to know, sholud i use pillow bearings or the weird kit from northern tools for my live axle? and how do you hook up the steering ? ive got my 2 tie rods and the steering wheel and pitman arm and all that jazz, now how do i connect it?:toetap05:

 

[Kaptain Krunch]

Is this the "wierd" kit from northerntool? if so, my go kart came with that setup, it does work but i would suggest pillow blocks, there cheaper and just as good.
