Thank you for the input. We need all the real-world experiences we can get to help us figure out what is, and is not a suitable replacement for Comet CVT's. I really hate to see guys wasting paycheques for nothing. Keep those reviews coming in folks! And maybe with a bit of luck, The OP will show up here for a rebuttal. I'm not holding my breath...

aight, looks lke i found the experts on TCs here.. ??

heres what im tryig to figure out...

with different series TCs, theres like series 20-30-40-500 etc etc etc..

it kinda seems like those referance the diameter of the driver..? is this correct?

like a TC40 DRIVER, 1 INCH BORE Torque Converter would be a 4" ?

a comet 500 is Diameter: 5-3/8"

im trying to figure out, if I get that 15HP (Which i've pretty much decided to do) which TC to get, as im sure i can utilize something better than a series 30, and since i'm missing some TC parts/pieces to have all 3 running, and the 2- n 30 series are only good for like 7-8hp units..

i was thinking the being as the shaft on said engine is 3/4s i could use the 500 series driver, and the 44 series 8.5 inch driven, (Because that would give my a wider bigger smoother range and higher top speed etc) but they use a different belts..

guess i'd be stuck with using the 500 series.. unless i had some kinda shim/shaft bushing/specer thingy to make the 1" TC fit on the 3/4" shaft.. prolly wouldnt be too hard if i took it to a machinest or something.. or even weld up the shaft and then machine it back down..

then i could use the 40 series driver and 44series driven..

I wonder what the 44series obsolete driver was...

hmm.. maybe i should get ahold of the engine first and verify its a 3/4 shaft as i've read.. lol

that 500 series is just so dang pricey...

i would go with the 40 series, its not hard at all to make an adapter, just get some 11ga steel, wrap it around the engine shaft, then cut a 3/16" section, and a 1/4" section out of it and sandwich it between the crank and the tc.

p.s. search for something like shaft adapter, there have been a few threads on this.

I'll get you a photo of my set up. I have a 1" driver on a clone 6.5. I turned it out of brass then split it and belt sanded it 'til it was snug. The 40/44 is much more common.

i was completely in the dark before spending last weekend here learning about TC's, thank you all for that. but, the reverse-engineering by chinese bid'nesses and the outright-FALSE claims they make is nothing new to me, the MB market is horrible with it. my opinion: 1) our gov'ment isn't doing enough to enforce fair-trade regulations, and 2) the american consumer brought this on by cheaping out. ok, enuff preachin'.

i just got this from GTC in response to my challenge:

We are not hotgokartpart.

We are in the USA, we make GTC Torque Converters in California

to which I've replied:
Thanks for the quick reply, Chris. No offense intended, but I don't mind telling you that many people are still waiting for believable proof of your "Made in USA" claim. Noone I've spoken with believes the photos on your "About Us" page are genuine, and frankly, I don't either. People want to buy American, but people want to know it's the real deal. How about some real-time photos of your building and your machinery actually making GTC parts?

more of the same vagueness so far...i suppose "make" could mean "assemble"...it happens with bicycle engine sellers all the time, they're constantly ripping each other off. and don't choose solely on the obvious difference in quality between the no-name and (maybe american) GTC, chinese bike engines also exhibit huge disparities in quality control of otherwise identical items.

btw-it looks like hotgokartpart simply c & p'd GTC's (as yet unconfirmed) "about us" info. also, GTC shares a common physical address with yet another player, gokartsusa. i seriously doubt the facility is a factory, likely only warehouse or maybe even drop-ship. who knows with these jokers?

since Comet TAV kits seem to have magically re-appeared, i'm gonna spend the (few) extra dollars. redsox has posted elsewhere some helpful info about this, and i got through to Comet by contacting Certified Parts Corporation. as soon as i confirm the direct-sales contact info i was given (she's out sick today) and find out if there's a savings, i'll post it somewhere appropriate. meantime, genuine Comet stuff can be had at BMI, Northern Tool, and a couple of Amazon stores.

(a blatant bump for some good guys: the Golden Eagle Bike Engine system IS "Made in USA" and offers only quality certified japanese engine options...either Tanaka 2-strokes or Robin-Subaru 4-strokes. you can also get their patented american drivetrain without an engine, and use chinese pocketbike & scooter engines, but i don't recommend it. ADMIN: i'm not affiliated with GEBE beyond friendship & being a satisfied customer.)

point is, Americans should buy American...it will slowly but surely repair our economy and force second-string imports up to par...that's my take on the matter.

NOW i'm finished preaching.

Well when I start selling TC's I wont fu** around. By the way, I wonder what GTC stands for ( General Torque Converter or Generic Torque Converter )

augidog, I think I love you. I laughed really hard when I saw how they all have the same text. I love how GTC won't answer direct questions or say how they are in the USA.

:iagree: with blaz. I wonder how many people thought they were realy getting an American made tc. Oh sure it was probably put together here but the parts came from China. Last August I was going around looking for products that I could put on my site. One was a tc ..... I found 5 companies that manufactured them over seas. 3 in china , 1 tiawan, and 1 more I cant remember.
80% of what we are seeing on the market when it comes to TC's now are mostly from china or the major parts are.
Red, If things go the way I want them to then yes I will be selling TC's .... but theres a catch, and its somthing that alot of you wont like, some will .... im going to leave it at that because I dont want to jinx it.

i just received a phone call from CPC/Comet...

the prices i was quoted were way high compared to retail sources, $95 + shipping for a 219552 (series 30) driver, $109 + for a driven. so that's that.

That's not bad if its American made, however it makes no sense to buy the two clutches individually if a vendor like northern tool can sell the series 30 kit for two twenty.

yup...right now individual parts are less thru BMI, but i agree buying the whole kit justifies the extra parts you get.

but what if the lower prices are from old stock? i guess the only way we'll know that is when Comet gets up to speed with new stuff.

still, even then, i'll gladly pay more to keep the money at home where it buys groceries for my neighbors, instead of helping make our economic problems with china worse.

by the by, no more info from "gimme the cash" in my inbox...i think we've busted them pretty good. but we're a tiny fraction who now know better, the clones will be cruising right along on ebay, and there's not much we can do about that.

Something I've noticed just from the stock photos, the NEWEST Comets are usually black, and the older ones just have a different look to the metal than the GTC ones do. Usually the included dust cover is a dead give away, but they just LOOK different as well.

Cool.... so i guess this means for sure i got a Chines clutch? At-least it works well, but i would still rather have a comet (of course comet came back into production a month or two after i broke down and bought the GTC). I think the back plate may be made in USA, but that doesn't change things much.

this thread isn't really about a part anymore...

and it isn't really about a country, either. this is a simple matter of ethics. "everyone's doing it" is gettin' mighty old.

see here, sometimes i buy a chinese-made bicycle part. sometimes what else ya gonna do, yaknow? but i shop like a good consumer should, and i'll spend $4 more for the best chinese-made basic wheel available. but i won't buy it from anyone clearly lying to me about origin or specs, or whatever else.

i looked at a TON of TC stuff in a very short time, learned a whole lot, then i applied the 6 years of experience gained within my own motorsport.

for a while there, unless one was lucky enough to locate real Comet stuff, you had to buy something made in china...and apparently Gimme The Cash was your best bet. as someone said, there's a notable difference 'tween the choices.

but if they have a competitive product, they don't have to lie, do they? even a bit of "loose" lying shouldn't be tolerated, and it surely shouldn't be rewarded.

i bet if you keep your gtc clean, and use oem Comet/Hoffco belts, it'll be fine. keep a close eye on those bearings, tho, i'm willing to bet they're the weakest link. maybe the springs. or those little nylon things. one of those i bet. or something else.

ok, with that said...i hope the new CPC-Comet kicks all their a$$es RAW!

(don't worry, guys, as soon as i score my TC i'll pretty much be outta your hair)
