Continuing this thread of trying to determine what belt I need to properly fit these pulleys, I have talked to Chris Wood at LMS but he can't help me with anything but OEM parts, so some math based on the gullet od + the tip od on the pulley, half of that to get the "pitch diameter" converted to pitch circumference, then divided by the number of cogs, 30 in this case, give me a pitch length of 4.60mm, and in cycling my digital caliper through its modes, one thing seems to stand out, 3/16". Are there belts made with a 3/16" pitch? This OEM belt that is now too short at 70 cogs, is actually different in cog heights, the old worn belt fitting the new pulleys much better than the new belts I bought, and indeed the old belt, turned wrong side out and fitted to the new one is a just noticeably longer over a 3" straight span, about half a tooths worth, than the new one. The new belts cog height is less than the old one also, by about .16mm. So at best fit, its sitting on the tops of the teeth with lots of daylight under it in the pulleys gullies. I don't recall running across a 4.644844738332509mm (calculated) or so pitch of belt anyplace in my web snooping so far. Ideas? Including me doing it wrong... Do I need to change my brand of toothpicks or what? Thanks & Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
