Torque convertor belt ?

[fishheds]

The gf's son just came by for dinner and he's scored a go-kart.
He says it's got a comet cvt,3/4"shaft.He's saying it needs a belt and I have 0 experience with torque convertors.
He also says Comet has gone out of business.Does anyone know what size belt we're gonna need to get this thing rolling?
Can we use a standard V-belt?
Thanks,David

Nope- standard belt won't do a thing for you. You need to identify which model CVT it is, and depending on that answer, measure the exact distance from pulley center to pulley center, and bounce that number off the Comet chart to find the appropriate replacement part #.

Ok,thanks toystory.I'll take a look at it tomorrow.

fishheds: Comet was out of business, but is back:

Certified Parts Corporation acquires certain assets of Hoffco/Comet

Certified Parts Corporation (CPC), the Janesville, Wis.-based company that purchased
TecumsehPower Feb. 9, 2009, acquired certain assets of Hoffco/Comet in an auction
Dec. 17, 2009.

CPC purchased Hoffco/Comet’s intellectual property, dies, fixtures and tooling, as well
as its entire existing parts inventory, shelf by shelf. Although the shelves were
somewhat bare, CPC still bought a large quantity of parts. CPC intends to maintain a
complete line of replacement parts and is very confident that it will be able to
manufacture complete finished product in the near future. Comet was in business for 60
years, making clutches for some of the world’s best known manufacturers.

“It’s a huge marriage between the Tecumseh engine and the Comet torque converter,
which is a variable-speed transmission,” said Jim Grafft, CEO of CPC. “They also made
a gear box that we are excited about.”

CPC hopes to start shipping in January 2010. “We have talked to many of the main
vendors, and they are excited that someone has taken over and they are looking
forward to shipping us new parts,” added Grafft.

hey toy story i have a 30 series TC and my belt # is 203589C MFG has the same number belt but its 203589A would that work ? did they just change the letter or is it a diff size? i checked the width of my belt and its a little worn down its a centimeter less than 3/4 im sure thats another reason its kinda lagging on torque and speed

 

[Doc Sprocket]

The letter at the end does not matter.

its a centimeter less than 3/4

A centimeter is 0.393"- pretty close to 3/8" (0.375"). You mean to say your belt is HALF it's original width?????

ok thanks here is a pic of what my belt looks like

 

[Doc Sprocket]

That is 11/16". It is worn down 1/16" from the original 3/4" top width.

so is that ok or should i be ready to order a new one this lil 5hp briggs fun power seems like its had some work done to it because put that new 12t on and the 54t is pretty worn down and i clocked myself at 36mph with my gps not sure exactly how acurate but with 20 inch atv tires on it i also did a lil paint job on the old cover

 

[r_chez_08]

Your gearing is well off. You are geared for 48mph @ max. 3600 rpm.
Change to a smaller torque converter sprocket and large axle sprocket.

well im 190 lbs so im sure thats why i have a spare 60 tooth that im going to try but it seems fine right now the 54t is def worn down like a ninja star lol im really just playing with them untill i sell them for a small dune buggy like a roketa or hammerhead
