Gearing Ride-on

[cjhols]

Hi all,
Very newbie here. I am just after some advice of converting my 11hp Victa ride-on into a Go-Kart. My question is about gearing. I see a lot of people use a jack shaft to transfer the drive but is this necessary. Couldn't you run a clutch off the engine straight to the diff of the mower?
If you could does anyone have any ideas of the size of the sprokets / pulley's you might need. The radius of the tyres is 9 inches / 22 cm's and the diff ration in the top gear is 9:1.
Many thanks

I am also building a Victa ride on racer! What model is yours? Mines an 80's pro12. From what I have heard, you put a larger pulley on the front and a smaller one on the rear. Do not take this as truth as it may be incorrect, do your research on that. Exact ratios and such are things I am yet to calculate myself. Is yours a friction drive like mine? I too am running a similar sized motor.

Hi,
Yes it's a bit of a quagmire out there. All I know is that it is off a 10 -38e victa. Looks around 1980's. I was thinking of just having the 2 pulley's or sprockets. It would be easier. I think it is friction drive. Do you know how to get the back wheel off? It has a bolt but the wheel hub looks like if is part axle???

Is your motor horizontal or vertical drive? If its horizontal, you may have to use a RAGB (right angle gearbox) which is basically a 1:1 ratio right angle diff type of thing. Your will also need a clutch or torque converter on your motor. As far as the wheels are concerned, I have not taken mine off but I know that they can be nearly impossible to remove sometimes (rust and corrosion holding it on). I have heard of people ditching their back wheels along with the axel because they gave up trying to separate it. Have a go and see what happens.
