How do you tell the difference between a tc88 and a 20 series?

 

[KustomKartKid]

tc88 used a 5/8" belt....series 20 uses 3/4" belt and is rated for more HP.....

 

[rmm727]

how would you know that without the belt?

Yes KK is a Know it all.:001_tt2:

maybe I worded that wrong. how would you know a tc88 driver or driven from a 20 series if you didn't have the belt?

Push the two pulley sheaves tightly together and accurately measure the width at the top...it's either 5/8 or 3/4.

Remember that the next time you call me (again) to ask if it "righty tighty / lefty loosey".....

Didn't know it was that simple. Hi-jack over. Carry on.

Since we're only talking about an 1/8" difference it would be best if you had a 3/4" (symetrical)belt lying around...push the two sheaves tightly together and lay the belt in...it should be basically flush with the top...

 

[rmm727]

Just tried it with a driven. Its pretty obvious. On the driver, I don't know. The part closest to the side cover was damaged. Wondering if that part is interchangeable between the two. They sell replacements of that for a 20 series. I got the driver and driven off of different machines in hopes one day I would have a matched set.

 

[KustomKartKid]

yeah the TC-88 and CAT99 symentrical series are obsolete and no longer supported by Comet....but you can still get the belts....

 

[rmm727]

After going through all that, I might be interested in this.

heres how you measure the driver (disreguard the lower part containing the 40 series, it came with the stolen pic :

Notice how you can add spacers to make it fit a 20 series belt. also I have read that you can use a 20 series and work the snout down to accommodate the 5/8 belt.

so if you need a 20 series, the TC 88 could also be made to work with a spacer installed:wink:
