chopper drive train, RAGB ideas

[Bluethunder3320]

so my clone needs a lot of parts, and 6.5hp in a little chopper really wont be that great of a ride. i still didnt know what to put my 13.5 Briggs flatty on. so i am trying to find a cheap-ish drive train so that i can use it....

options:

• mount engine horisontally

probably cant do this because this engine has a crankshaft counterweight mechanism that comes in VERY close clearance to the rod. also the crank case is huge.

• RAGB

would probably be the easiest, but the cheapest i have found is around $150. i dont want to spend more than 70-80 if i go this route.

i could also make a home made RAGB but i dont know where to start as far as how to support the shafts and make a very strong gear mesh for the 13.5 HP...

• bent belt

special kind of belt. i am not sure how this would work but it may be the most possible... i have a bent belt come off the engine shaft pulley and onto a jackshaft behind the engine...

• arien's style friction plates

i have been working on a arien's mower... actually swapping a crapped out SH!tty 6.75 OHV briggs for a good old 6hp briggs flathead. and the drive system has a belt driven disk with a roller that gets pressed into the rotating disk. maybe take one off a snowblower?

any other ideas?

im not sure where the tractor battery will go... or maybe ill get a motorcycle battery.?

****the engine wont be mounted like this, but this is the only way it would fit just to show the engine and bike together.

i still wanna see someone make a ragb outta an old car diff

iv seen a tiny one in our tafe workshop that would be perfect

 

[Bluethunder3320]

yeah this bike is pretty small though haha.

i dont know what to do! ahh! its like, i have a good size engine but need a way to connect it to the wheel...

This might prove quite difficult due to space constraints, but do you have a GOOD mower tranny (like a Tec-Peerless 7-800) available?

It might even result in yours being the only mini with reverse!

 

[Bluethunder3320]

i have this one, but its going (maybe?) in my tractor... if i use it for snowblowing..

also have a 5 speed peerless but i need the case welded up because it cracked.

and i would have to like.... lock up the diff and put a sprocket on one side going to the rear wheel?

 

[porsche930dude]

a modded clone will work great on that. Just run a jackshaft so you can get good gearing and youll be haulin a$$

 

[Doc Sprocket]

Lock the diff? No. I meant mower transmission, not transaxle. A transaxle would be way too bulky for the task.

yea i always use clones though haha. and the one i have needs alot of parts

i have a push mower tranny if thats what your talking about. its small. one lever to engage. one speed. craftsman. think it would take 13.5hp pulling a bike though?

No, I mean RIDING mower transmission. To explain

A transmission is the means of transmitting power from the engine to the axle. A transaxle, INCLUDES the axle. So- Transmission= one output to feed the axle and in turn, the wheels. Transaxle= TWO outputs, includes the axle and each output feeds each wheel.

I think you have a photo above showing a transmission.

theres an axle on the other side. (sadface)

cant find any mowers with transmissions. lol

 

[Doc Sprocket]

Oh, my bad. That explains the weird shape, sorry.

If you are interested you can have the motor and tranny out of this

Hey, is that an old Cub Cadet? My neighbour's got a couple for his kids and they're really neat!
