how do you get this off?

[newcart]

Hi all I got my yerfdog running and the bearing blew up so i need to remove the pully and I can not seem to get it off can someone help please

It should just slide off.

It should just slide off.

I was just looking around and most of the ones I see have a nut on the shaft this one didn't have one.
I was trying to figure out how to get it off even hit the shaft lightly with a small sledge and it didn't move

I'd say try something like pb blaster and soak it then try again

Dont hammer directly on the end of the shaft. Use a piece of wood, or a a punch smaller than the shaft. Use penetrating oil on it. If you have a hand held torch that will help too.

Heating and cooling, penetrating oil, vibrations and patience it will come off.
Just be sure to use some anti seize when you put it back on.

how about you remove the snapring first!

And just looking at the pics, and the snapring shown in it,
I wonder why I read PB blaster comments tbh..

Thanks all
I did try and remove the snap ring but it looked like that would only remove the outer part of the aluminum section, and that didn’t come off either. Is there a set screw under it

Get some CRC Freeze Off. I've used it to remove seized parts before, and it works pretty well.

Does anyone else think that something is up with that belt?

What do you think is up with the belt?

Its sitting too low. Normally at a standstill the belt should be all the way at the top of the driven unit. It should be nearly flush with the two sheaves. Manco and TAV belts are generally shorter than Yerf-Dog belts, and it looks like your's is too short. Get the number printed on the belt and the center to center distance of the driver and driven units and use this link to find if it is correct: https://www.gokartsupply.com/tcbelts.htm

I was playing with the pulley while trying to get it off and i don't know if I moved it down
I will look into that thank you

I would see if you can get the axle to move in instead of pulling the driven unit out. A deadblow hammer and a wooden block on the end would probably do some good, especially with some heat. Do note, the driven unit has plastic "buttons" that are vital for operation so don't melt them. Would put some aluminum foil or something over them as a heatshield.

Wouldn't that be because it's too thin aka worn out?

Even if it got thinner, it would only slip and flop around on the pulleys. It wouldn't go in that far. I mean its like a full 3/4" in.

When I got my one kart it had a 5/8 belt with a 3/4 in. Pully

Possible, as the belt has significant slop. AFAIK the belt should be nice and tight.

Nope. The belt should not be tight at all. They should nearly be so loose that you can take the belt off the sheaves with a little bit of effort.

There are charts though to select the correct belt for the correct center to center distances between the driven and driver....so there is no guess work involved

I thought that for a 20/30 series, when squeezed and pulled forward, the correct belt would have about an 1/8" gap between it and the bushing on the driver. But I might be wrong.

Although I think that you are right when it comes to 40 series torque converters. Either way, a sizing chart is always helpful.

I agree. He must get get the correct belt after looking at the sizing chart.

Thank you for the advise
I ended up using a small sledgehammer and wood which drove the axle out, the end threads are in bad shape and the key was bent between the driven unit and the small gear. I ordered a under sized and a exact size key to replace it (not sure which one would work better)
Also I broke down and bought a new pulley system and belt to make sure everything is ok
