My "new" CAT99 torque converter

[redsox985]

Sorry about so many photos but I wanted to display it all. I know I should have looked at it closer before disassembly to sand and clean with good 'ole gas but I didn't. Would someone tell me how all of this goes together? I know I'm missing one of the mounting bolts, it's somewhere in my garage/basement. Also, those little "teeth" made of ?nylon? in the first photos worry me. I'm also concerned about the rust on the inside of the driver. Any opinions/suggestions/comments would be great and welcomed. Thanks a lot.

EDIT: I'm assuming I need to drill and tap my drive shaft to keep the driver on the shaft? If so, does anyone know the size and TPI? Also, I'm going to purchase a converter sleeve because it's a 1" driver and 3/4" shaft (clone). Lastly, how do I properly tension the spring?

get rid of the rust. (nylon stuff is supposed to be there you should have 3 of those nylon peices) and picture shows how it goes to gether, in the picture it shows a back plate with a jackshaft you may need to make your own jack shaft youl also need the correct size belt.ou can get some info on it here http://www.google.com/imgres?imgurl=http://www.gokartsupply.com/img/tqdif.gif&imgrefurl=http://www.gokartsupply.com/identify.htm&usg=___YHmS-majjSJMGhf4_BZzivgRck=&h=195&w=242&sz=3&hl=en&start=2&um=1&itbs=1&tbnid=brvvaDe65M5TpM:&tbnh=89&tbnw=110&prev=/images%3Fq%3Dcat99%2Btorque%2Bconverter%26um%3D1%26hl%3Den%26sa%3DN%26rlz%3D1T4ADSA_enUS365%26tbs%3Disch:1

i think you may be missing part #5 in pic above and to re calibrate the tc the spring on the driven pully should be put in the 3rd hole i think and is that doesent do it you can adjust the springs in the driver. for the bolt yes you will need to tap the shaft if you are gonna use hat bolt but the easyest thing is to keep the hole in the crank the same dia and use a smaller bolt, also youl need a longer bolt to reach you crank shaft thats probably only 2" long also the driven unit has built in keys which you may have to cut of because the shaft sleave you are prob using has a stepped key to hold the sleeve on

 

[r97]

never mind about missing part #5

I do have the jack shaft assembly and backplate was limited to linking 15 photos so I dumped those. What concerned me was how worn the nylon teeth were, not that I have them.

 

[r97]

if you think there to worn get new ones from the link i showed you earlier
p.s if you have alot of pics make another post and fill it up with pics!

I'm just slightly curious, who happened to tell you that this was cat99? I'm not 100% without having this assembly in front of me but I believe you just have a series 20 assembly with 1" driven, is this symmetrical or a-symmetrical?

 

[redsox985]

Asymm. I forgot where I looked but it does say CAT99. Also, does anyone know what size retaining ring will fit the cam on the driven clutch. It was jimmy rigged with washers but I'd rather do it right. Does the one sold for the 20, 30, and TAV fit? If not, where can I find one.

 

[redsox985]

Ok blaz you got me thinking. The black cover says that its a CAT99. It's obviously asymm. but the driven is stamped 3/4.

 

[Blazkowiez]

The pictures do throw things off(no overhead view), and the spring is cat 99 (very similar to the spring in a max-torque driven). We had to get those rings from granger's supply btw, you can order it there. So are you saying the driven may be symmetrical or the whole system is a-symmetrical? Tryin to nail this down for ya.

Go here for all the TQ info you will ever need

[redsox985]

The whole system is asymm but what confused me was that the driven was stamped with 3/4. In my mind this means that its not a CAT99 with a 5/8 belt but a 30 with a 3/4 belt. Just me being optimistic that this MAY be younger than me.

EDIT: Would you like some other views? If so what?

 

[r97]

maybe the driven is supposed to be mounted on 3/4" shaft?

 

[fowler]

its not a mixture of comet and CAT parts is it

 

[r97]

i noticed the side of the driven says 20 if i remember correctly that means is a commet 30 series right?

 

[r97]

i think what youv got here is a cat99 driver with a commet 20 series

 

[fowler]

i think im right (if that even works)

 

[r97]

unfortnatly, i think me and fowler are right. of cousre if you get a cat99 driven and a 20 series driver youl have 2 tc!

 

[Kenny_McCormic]

Ignore all those numbers, they dont mean anything to us IIRC. Like I said http://www.gokartsupply.com/identify.htm

 

[redsox985]

Both driver and driven are made for the asymm belts, not run on the 20 series. The 20 is a 20 degree cam. It made to run on a 5/8" jack shaft which I got with the unit. Fowler I don't get what you mean, the CAT99 was made by Comet.
