Making my own TAV

[Jdominique]

Ok, I have a 30 series driver and driven unit off of my old Manco 285. I found a place that sells the TAV back plates. If I bought one of these, what would I need to make a complete kit? I'm thinking I'll need this:

Bearings for the driven unit mounting hole
A small jackshaft to fit in the unit (no idea what size)
Bolts to hold it to the engine (no idea what size)
The black cover (I found these for $15)

Is this possible and what am I missing?

Thanks,

Jason

Go find a 49cc TAV and convert it. Made for little motors, but they seem sturdy. IMO at least.

a tav for one of them will just melt in something like this dude. anything made for them that you think would be good wouldnt.

well, if the parts can be had i dont see why not. the shaft for the driven is 5/8 and i think 3/16 keyed. the bolts will probably be a 5/16 24 fine thread and the cover isnt critical unless you are sloppy with moving parts. dont forget belts

Plenty of people mod these 2-3HP stock motors up to 5-7HP... I don't see why it wouldn't work.

I own one, I think I'm allowed to make assumptions here. Do you?

It most likely wouldn't stand up to the more aggressive torque from a equivalent sized 4 stroke. 4 strokes are much more thump thump slow aggressive torque. The kind of torque that tends to rattle things loose.
