Desperately Need Help

[Sanch109]

I bought my first go kart that's in pretty bad shape that I thought only needed an engine to run. I am having problem after problem and I need help making it run.

I bought a new motor, predator 212 hemi, but I am not sure how to connect it to run the tires. It came with some type of torque converter that does not work. I am not sure what I need to do regarding replacement parts because of the set up on this particular kart. A regular torque converter doesn't seem like it would work because the current blue driven pully seems pretty far away.

Also, the plate by the wheel with the sprocket is too small for me to mount the engine there. ugh. So many problems with this kart.

Please help me out as I want to get it running for my boys.

Let me know if I can provide you with any more information and I will do my best to explain as I am a novice.

Please hold for the next available technician. One of our resident experts will be with you shortly. Your call will be answered in the order it was recieved. You are currently number 7,954 in the que.

While screening your request l did notice that the belt you are using doen not look right.
The CVT requires a special belt. I unfortunately do not know the specific one. We do not encounter belt problems very often. Please continue to hold, you are 7953 in the que.

The secondary looks like it is a 20 series and the primary looks like a 30 series. That will not work!!!! You need a 20 series primary and the correct belt for it. GoKart Supply will have what you need if that is indeed the case. I would like to see a direct top down picture of the secondary without the belt to be 100% sure.

 

[Sanch109]

The belt is definitely wrong. It's an auto parts belt.

What about the secondary pully, blue one, being mounted on the way it is? Is it on the right way?

All the torque converters I have seen on Amazon are connected by a plate and are close together.

Is my set up normal to where the two pulleys are further apart and disconnected?

 

[Sanch109]

Here are some top-down pics of the secondary. It's night so the pics are not the best.

The way your secondary pully ( called the driven clutch ) is mounted and located is perfectly fine. The driver and driven much be compatible. Same series. Your driver is a 30 series. Your driven may be a 20 series. That is why Denny ask for a picture taken from above with no belt to determine if it is a 20 or 30. Help us help you out by providing that.

 

[Sanch109]

Sorry but I am completely new. What information do you need? I thought I did provide the pictures of the Driven Clutch with no belt. the 3 pictures above.

Do you know what parts I could but for replacements? This Kart was left out in the rain for a long time so the pulleys are probably not working.

I am assuming I would need a Driver pulley, a driven pulley and a belt but I am not sure which ones to buy and where to buy them.

Thank you so much for the help so far. I am glad to know that the pulley mountings and locations are fine.

Looks like the driven on your kart is a 20. You need to buy a 20 series driver and 20 series belt. Belts come in many lengths. Measurements needed are the distance between the center point of the two clutches, and the overall diameter of your driven clutch. A 30 series ( much more common ) will not work. Whoever you buy the 20 series driver from will also have the correct belts.

 

[Sanch109]

The distance between the 2 center points is 9 inches.

Where could I buy the pulleys and the belt so that they all match and the kart will finally be able to run. This is a pretty big learning experience for me.

Go kart supply. Go Power Sports. O M B Warehouse. All have websites and e mail available technical support. Sometimes even on the phone if you are patient.

 

[Sanch109]

I am definitely patient. I have put in too much time and money to quit on this kart. I want to get it running for my kids.

So what do I ask them exactly. I am not sure how to relay what I am looking for to them as I am not able to show them pictures of my set up. I just want to know how I make sure I buy the right parts.

 

[panchothedog]

Make sure it's not 8&7/8 or 9&1/8 the increments are pretty close. You also need the diameter of the driven. The big one that's on your kart. It will be in even inches. Like 6, 7, or 8. All of those websites should have a chart showing distance between and diameter of driven, as that affects the length of the belt. I type very slow, that's why I didn't see your pictures.

 

[Denny]

You will need a 20 series primary for a 3/4” shaft and the proper length Max Torque or Comet belt. You pictures confirmed you have a 20 series driven. Good job on the pictures. I know GoKart Supply used to carry all the parts and belts. They even have a tutorial about how they work and how to measure for the correct belt.

 

[Sanch109]

I am on the go kart supply website now but there are so many parts to choose from. I am not sure how to pick the right parts.

I just did a rough measure for the 9 inches from center points with a measuring tape.

It looks like the diameter of the Driven pulley is 8 inches.

 

[Sanch109]

I am looking at the belts now. It is pretty complex with 2 center distances listed for each belt. I just need to know how to read the belt center distances so I get the right one.

I have a predator 212 motor, so that is the 3/4 shaft for the primary pulley.

So I need to buy a 20 series driver and driven pulley right.

How do I find out what size bore the Driven pulley is? I show that the website has 5/8, 3/4, and 5/8. However, they only have 6 inch and 7 inch driven pulleys. I measured my driven pulley at 8 inches.

 

[panchothedog]

A driver and a belt. Probably wouldn't hurt to get a new chain. It is usually sold in 5 ' lengths, so you will need a chain breaker tool. DON'T waste your money on the $8 one. It very well could break on the 1st use. Mine broke on the 2nd. I bought my 2nd one from a motorcycle shop for about $30. They said it was the same thing their mechanics use and it works good. You might also have to service your driven clutch. Take it apart, clean with brake parts cleaner ( no oil or grease ) and put back together. Lots of videos available on how to do. Process for the 20 and 30 will be the same. Only real difference is the angle of the pulleys. You will need a good set ( not light weight ) of snap ring plires to disassemble and reassemble the driven clutch.

You have about a mile of ajustment available.

 

[Sanch109]

So it sounds like I will not have to buy another Driven pulley. I will just need to take it apart and clean it with break cleaner.

I have a chain and a chain breaker in the mail from amazon. I may have to buy those again as there are some bad reviews.

So I would need to buy a 20 series Driver pulley with 3/4 shaft and the belt. I am looking at the comet belts but they only have 6 and 7 inch pulley options.

 

[Sanch109]

Regarding the adjustments, thank you for noticing that. That didn't even come into my mind.

How does that change things? It seems to me that the center distance is now variable and I don't know if that makes it harder or easier to find the right belt.

 

[panchothedog]

You don't need the driven. It's already on your kart. The shaft of your predator engine is 3/4 ". Make sure you are not looking at a chart for 30 series belts. The technical guy at OMB Warehouse is very responsive. Usually the next day. Give him your measurements and he will get you a part # from their store. From the tone of some of the questions you ask, I hope you aren't in over your head. It's going to take some tools and a little mechanical aptitude to get the kart back on the road. But please don't hesitate to continue to ask questions. That's what this forum is all about.
