View Full Version : help me identify my timing chain please. jester1 03-19-2007, 06:08:04 PM The chain I have installed is a billet roller with a torington bearing and the only numbered stamping is ( s-288 and TGC ) anyone know who the manufacture might be? thanks http://i119.photobucket.com/albums/o152/raceinno/IMG_0487.jpg rindoze 03-19-2007, 06:25:49 PM why the hell would it matter? jester1 03-19-2007, 07:57:24 PM it matters to me pdq67 03-19-2007, 11:18:13 PM Flat donno, sorry. Tried a search for TGC and didn't turn up anything.. Oooop's just thoughtta this, try "Torrington Gear Company"... You might get lucky?? pdq67 LTjames 03-20-2007, 01:47:38 AM Looks like PDQ67 nailed it...I think. Did a quick google search and came up with this cloyes version that looks similar but not the same http://www.shafiroff.com/images/tru_roller.gif 74RAT 03-20-2007, 01:54:32 AM jester,, the s-# appears to be a sealed power intechange numbering system. the cam gear doesn't appear to be a billet gear. maybe it's a steel one,, but a billet gear will be machined fully from a billet block of steel. not cast so to speak. see if a magnet will stick to it to know that it's not aluminum. i'll look in the speed pro catalog tomorrow morning and get the individual gear/chain/crank sprocket numbers. and the set number for the boxed set. hope it helps. i'll post back. jester1 03-20-2007, 02:03:23 AM jester,, the s-# appears to be a sealed power intechange numbering system. the cam gear doesn't appear to be a billet gear. maybe it's a steel one,, but a billet gear will be machined fully from a billet block of steel. not cast so to speak. see if a magnet will stick to it to know that it's not aluminum. i'll look in the speed pro catalog tomorrow morning and get the individual gear/chain/crank sprocket numbers. and the set number for the boxed set. hope it helps. i'll post back.

You might get lucky?? pdq67 Ill try that now thanks. I did a search for tgc and s-288 and turned up nothing. However is did see the number s-288 on a lunati chain, called the tech and I swear I think the guy was drunk, seriously.:confused: :eek: He had no idea about it or what was going on. Man I think I know where his paycheck went.:screwup: 74RAT 03-20-2007, 06:40:22 PM jester,, i'm thinking it's this one: speed pro book part number for the 3 piece set shows 220-3110T. shows as .250 double roller with torrington bearing. shows 3 keyway timing gear at the crank. this catalog doesn't give the 3 piece breakdown on the individual parts for their numbers. only as a set. if you can caliper some rollers on the chain,, you will know. they show the 220-2110 as a .200 roller diameter and the 220-3110 as the above mentioned without the torrington bearing. i'll dig arround through another sealed power book to see if it has the separate numbers for the gears/chain. it lists part#222-168 as the number for the .200 chain by itself or chain only for the 220-2110 set. more to come if available. jester1 03-20-2007, 10:30:21 PM you da man RAT! How well do you remember the theroy? If you replace one gear then you should replace as an assembly but if you keep the gear you can replace the chain only is this correct? I cant remember for the life of me. Did you by anychace come across what the max chain slack that is allowed before replacement? I calipered the rollers at .200 |
