Hello, new to karts and current project (Manco 3005B-09)

[Stokes]

I picked this up for my son and am in the process of getting her in shape. I slapped some paint on it and am getting ready to install a new torque converter/sprocket/chain. Kind of difficult cross referencing parts, it has the 5hp Robin engine on it. Any help for compatible parts/kits would be greatly appreciated

Kind of difficult cross referencing parts

Welcome to the struggle! It's more fun that way when you're refurbing a kart that is long out of production.

We usually go on an as-needed basis. If it's just rusty, we remove the rust and paint it. If it's toast with cancerous rust or damage, then we replace or repair.

What parts do you need?

thanks for the reply

the most pressing issues are both sprockets and accompanying chain, as well as a new clutch.
Being that im not familiar with them im uncertain of the superseding direct bolt in part numbers. I believe i will have to go with a different tooth count and want to ensure i order the right parts

Torque Converter "TC" or CVT is a great choice as the kart originally came with a chain driven jackshaft assembly. The TC will improve drivability to a great degree.

I wonder if a 30 series TC is what you need, or a 20. Stand by, we have several gurus here on the forum.

Too many pictures of the front end and nothing on the important end. The engine and the drive train. Is it live axle, or one wheel drive? If the output shaft of the engine is 3/4", then a 30 series torque converter ( about $70 on Amazon ) will work real good if it's live axle,( both rear tires receiving power ). If it's one wheel drive then figure out if it has a #35 chain or a #420 and get a new clutch that matches the chain and sprocket on there now with the least tooth count possible. Your rear tires are on the large size for using a clutch.

Is there really that much variation for the 5hp Robin engines?

What do you mean exactly? Engine should be fine but the drive train is what we’re concerned with and the retrofit of a TC unit. Show us some photos of the engine area so we can see if there’s any interference issues when adding a TC.

I slapped some paint on it

I would’ve just worried about the mechanical condition, plus the remaining red paint and scars were cool. That big rusty spot on the floor pan needed attention though…..

I keep seeing that shade of blue turning up. What paint did you use?

 

[panchothedog]

Shaft size and drive train are what's important to be able to give you advice. Cross referencing part #'s will be of little value. Very few original ( if any ) parts available. Most go kart parts today are generic and will fit a wide variety of karts.

Its stock from what ive seen.
Also, the boy likes blue.

its just Ford Blue tractor paint. Nothing fancy

 

[Hellion]

I think Stokes' kart has a jackshaft so that may make a difference or be utilized when adding a CVT. Idk. I looked at the exploded parts diagram, that's all.

 

[Stokes]

I commute to work so had to have someone send. Hope this contributes. Appreciate your help so far. Im assuming everything is stock. If you guys have recommendations for better options that arent considered stock please feel free to mention it.

 

[Stokes]

Would this be applicable here? Its an EX130D500527068

See, now this is why we are always hollerin‘ for pics up front. It saves time… and aggravation

Now that we can clearly see the kart already has a torque converter/CVT, you don’t need a new one. Just service the old one. Our team of experts will be by shortly to advise.

 

[Hellion]

I must conclude the Subaru Robin engine is original to the kart, it is highly unlikely to be a replacement engine as they “don’t grow on trees” or as abundantly as other engines. I have heard it described as a high end, quality engine possibly on par with Honda and parts will be expensive just like Honda.

Consider buying a Predator 212 as a backup/spare/replacement engine. There’s a coupon in Harbor Freight thread, $119.99.

 

[Stokes]

The engine runs beautifully. Its seems like something isn’t engaging with the torque converter. I also need a new sprocket and chain. At first i thought that was because of prior use but possibly the wear came from the torque converter issue?

 

[Hellion]

Which sprocket? Might be time to start taking things apart for inspection.

If the chain(s) and sprockets are still 420 per the specs, you may buy some bulk 420 chain and learn to break chain. Buy a spare 420 master link too and a chain tool might help.

 

[Denny]

It almost looks like a 20 series CVT. But I would need better pictures to tell for sure. Juggernaut not worth the money or hype.

 

[JimD]

Manco only used the series 30 they didn't want to carry two different styles to confuse customers so Max-Torque only sold them clutches and Comet sold them the t/c. Denny you didn't mention what kind of belts to buy--I always thought that was automatic from you.

He should get rid of all the extra crap on the front of his driver unit. Correct bolt length 5/16-24 x 1 3/4" long. Looks like he has the correct insert for the inside of the driver. If his plastic wear ramps are worn he can always swap with the spare ones on the opposite sides since they will never get used on the trailing side and they are just that -spares. The hint to check all the keys to see if missing or sheared was very good.

 

[Denny]

COMET!

 

[panchothedog]

That picture of the driver is absolutely horrible. If you don't have access to the correct length bolt as recommended by JimD, do you not at least own a hacksaw? The juggernaut, torque-a-verter, and the other one you mentioned, are only useful on modified, ungoverned, high rpm engines. And even then, are highly overrated. I have one on one of my karts with a very modified engine, and would not spend the money on a second one. Once you get your TC working properly there are ways to modify the stock one to equal the juggernaut. Honestly though, with a stock 5hp.engine you aren't going to benefit from TC mods. Just clean it up and get it working properly. Tons of videos showing how to do it.
