Default Peerless

thinking about building a kart from old lawn mowers I have laying about. the one may have a peerless 6 speed trans. now I know everyone says stay away from transmissions on go karts. now I have also read that if your gonna use a transmission that the peerless is the only one that holds up to the go kart use, as long as you don't shift on the fly. my big question is can you get the peerless to work with a horizontal shaft engine or do you have to stick with the vertical shaft engine? has anyone here done a kart with a peerless and if so did you use vert. or horizontal? and do you have pictures? pros and cons and all comments welcome... I am in the planning phase so nothing is out of the question. and fyi I have access to a machine shop, so minor custom parts are no big deal. trying to avoid massive custom building but done mind minor challenges. and before you ask no I am not sure if it is a peerless that is in the mower or what model peerless it is if it is a peerless. I will be looking at that tonight. photos to come if its not to dark out.

Peerless trans are often used in racing mowers with a few mods. The thing is, if you use one with a horizintal shaft engine, you need yet another piece of equipment, unless you rotate the engine 90

Not quite; while certain types of belts can not be looped to change the angle they run at (i.e. torque converters/ TAV's) standard V belts can be twisted in their orientation within certain length constraints between the pulleys combined with the actual angles involved.

Then, there is a belt that is designed to be used in the type of setup the OP may wind up with. It's the hexagon belt.

You can even give these things a 180* twist to reverse the direction of rotation of the driven pulley; if done properly, it won't harm the belt in the least.....

Actually, they've been around for decades. I may well be wrong, but I believe they have come up at least once before since I joined the forum.... (If I knew how to look for it, i would reference it...)

EDIT: I can even get a limited selection of sizes from my local hardware store....

I've got a 1950's vintage pull type combine that my Great uncles bought new; it has had one twisted 180* on one of the clean grain elevators as long as I've been around it (~40 years......).

no need for all that fancy belt work. just stand the tranny on end so the pulley is verticle. just have to orient the engine so it spins the right way. you can even use a v belt clutch on the engine so you dont have to deal with the manual clutch if you wanted. but the transaxle should be race prepped. usually involves replacing some of the bushings with needle bearings and running a mix of gear oil instead of greese. thats the main thing. and getting it to not leak out

That would only work if he has a transmission only; if its a transaxle, where he's using the stock output shafts for the axles? Probably not....

that's the picture my dad sent me off the two mowers. I think the Toro on the right might have a peerless not sure what the craftsman has. Waiting for it to warn up past 20 to flip them over and look.

The one on the left, looks like a hydrostatic unit. The Toro might be disc driven with shift on the go. Neither a good choice for what you want to do. You can use a hort'z engine with a belt going to a right angle drive and then another belt going to a transaxle. The belt from the right angle drive to the transaxle you would have to have and clutch idler combination so you could shift the transaxle. Remember transaxles are not built to shift on the go, unless it is a VT transaxle. Also there are brakes to be considered. All this would be some serious fab work but it can be done.

those probrobly have a peerless differential. if thats the case your best bet is to forget about the trannsmissions and go directly with a clutch and jackshaft or a torque converter. You can sell the transmissions for about $75. each and buy the rest of the parts you need

If those are Peerless transaxles there is a part number behind the brake rotor, or there could be an I.D. tag riveted to the case, tell us what the number are.
