40 series torque converter installation

[@fatbuddycat]

Amazing. That thing looks humongous but very awesome!! I never would have guessed it can go on backwards either! Thanks for the lesson Eric!

[@lsj624]

This kit is perfect. The steel plate alone weights over 9 lbs. Very heavy duty. The bearing sticks out like that to put it closer to the sprocket. The RED spring on the Driven pulley is already the correct reverse spring and works very well. Comet just paints there spring yellow. Good job Eric.

just what i needed my secondary is just skipping on top of the pads and not engaging i am currently waiting on the reverse spring but the last tracking i have for it is passed through the usps jamaca NY international sort center

[@MrJakedaddy]

Do you have a video of this running? I’m curious as to how long the belts last as one side is generally slanted in more than the other.

[@duanefrey2449]

Hi Eric, what can I do to stop my primary from grabbing the belt @ idle tried a new belt same issue idle is set as low as I can go duramax 440, I put into a b200r coleman thanks I'm puzzled

We can change the springs in the driver to the red springs to get the driver to engage at 2000 rpms www.ombwarehouse.com/comet-40-series-red-springs-set-of-3.html

I have a 301 predator engine. Will that torque converter fit into a golfcart to replace the gas engine which locked up and rusted. I don't understand how to connect this to rearaxle without a drive shaft. Lost in Ohio. Need help for this 82 yr old folk

[@-OokySpooky-]

Whats the difference between a series 30 and series 40??

[@TheGrayGoatGarage]

The difference is the amount of HP and torque they can handle

[@AJC-jo3ds]

Can you use this on a 212 predator? I currently have a 30 series and break belts often…

[@rf4215]

Question maybe you can answer. Yerf dog go kart worked before breaking swing arm. Replaced it with identical swing arm and also identical sprockets and chain. Put it back together and belt slips...won't propel the cart. Driver and driven unit are used but were working before.

[@igokarts4510]

On the driver/driven alignment the driven moving sheeve should be matching the drivers fixed sheeve at full engagement. This will cause a bit of misalignment when not active. Does that seem right or am I losing my sh!t?

[@TheGrayGoatGarage]

I don't know if you are losing your stuff, but I can tell you that does not matter with these units. The symmetric belt is forgiving. Also consider that the original Comet units used the driver mounted conventionally and the driven had the hub inboard...same thing as what you see here, just in reverse! Trust in the Goat...you will be fine!

Hello Eric, longtime member of OMB had a quick question for you what size bolt goes in that crank good old Amazon sent me the wrong hardware for my torque converter that I’m putting on a predator 420 hemi I can’t believe Amazon messed up lol😂

[@zombiebloodsparkle1]

Hey, I have a question that I cannot seem to find an answer for anywhere. I want to install a 30 series on my go-kart, but the problem is that the sprocket needs to be on the outside instead of the inside. Is it possible to place a spacer where the sprocket would have been on the inside and mount the sprocket outside?

[@TheGrayGoatGarage]

Nope! That will put too much pressure on the plate and it will break!

[@zombiebloodsparkle1]

@@TheGrayGoatGarage If i weld a piece of metal to the cross bar and add a bearing that goes on the shaft would that help hold it up and prevent it from breaking?

[@ronp5778]

Hello, I have a question. I've read that the 30 series tq is good up to 8hp or there about and a 40 series tq is good for up to 16hp or so. My question is would there be any performance gains by using a 40 series tq on a built 212cc predator engine putting out 15hp? I realize you would need to put a sleeve on the 3/4" shaft to bring it up to 1" for the larger front pulley to be used.

[@TheGrayGoatGarage]

The 40 series units are very heavy and the snowmobile guys have been known to break cranks. There is a 40 series driver available for 3/4" cranks www.ombwarehouse.com/comet-44c-magnum-drive-clutch-3-4-.html but I do not recommend using it unless you add an outboard bearing and support for the weight. I have seen 30 series converters used on 16 HP engines. There are some modifications that must be done, but they will support the power. The 1" drivers use a 1/4" wide key and the 3/4" cranks and drivers use a 3/16" key. That makes it very hard to adapt!

[@cristianalonso13]

Hello good sir. So i instsalled this but my go kart wheels spin on idle. I noticed my clutch doesnt go all the flat and is still out a little .could this be my issue? I ordered a new cluth. I hope it helps lol

[@burtonexoticbullies.2313]

I just asked him the same question did buying a new clutch work? If so what kind did you buy?

[@marjuspjeci4097]

hi, I also fitted the same kit, when I walk 2 km I touch the belt and it overheats why?? yours is the same i.e. does it overheat??? or is it normal?

[@KVofficial112]

Can you use a belt with the set up instead of chain?

[@TheGrayGoatGarage]

I am not sure what you mean by that. The torque converters use a belt between the two clutches and then a chain to the axle sprocket. I am not aware of a pulley for a belt that will go in the torque converter

[@Cherokee-sz7xi]

I got a 40 series china made. 420 predator turning ccw looking at shaft,Do I need the ccw green spring on my driven? Thanks

[@teeter-built5288]

Can you mount a sprocket on the backside of the the mounting plate behind the engine? Or does it have to be between the mounting plate and the driven pully?

[@morraderi]

Great video. It is indicate for what power?

[@TheGrayGoatGarage]

A40 series can handle up to 25 HP when geared properly

[@ligmaballs1405]

My driven pulley bolt is too long for the amount of thread I have. Did you use a different length bolt?

[@TheGrayGoatGarage]

No, I did not, but we have to work around Chinese tolerances. Get a shorter bolt at the hardware store and you will be fine!

I installed the same kit just the way you did and did not put a reverse wound spring and my golf cart only does 10 miles in hour and rpm go really high. Is this because I need the reverse wound spring? Please let me know and thank you

[@TheGrayGoatGarage]

Yes. Without the correct driven spring as soon as the driver clutch engages the belt the driven gets yanked open.

[@TimothysTractors]

You might also consider a larger sprocket. I had the tiny sprocket that was included and got 6-7mph on my golf cart. Upgraded to a much larger one and am getting over 30mph now.

I would really need my hands and eyes on it to know what is happening here. Make sure the inner pulleys are aligned properly. If so, you may want to try another belt. If using the plate mount system, this is the best belt you can get www.ombwarehouse.com/-9-7-belt-asymmetric.html This is only for the plate mount systems

You are showing a steel and aluminum back plate. The unit comes with an aluminum back plate. You are not using the aluminum one that comes with it, why? Where did you get the steel one that you are using? Did I miss something you said or meant?
