The cog looks like a great system and I guess like everything else it works well when you get it right. That said before ECS came up with it many were getting by very well with the flip drive without issues. Every time something new comes out, it seems what was fine before it is thought of as garbage. Seems silly to me.

it's all about $$$$

I know what you mean.

Pulley seems to be in line, but it's just 2 pulley's. Crank and accessory pulley. Nothing really to adjust and with the other 3 belts running fine, I'm kinda stumped.

Every time something comes out, it's said to be "the only fix"...........until something else does. I find it comical watching it happen.

I don't have the cog, and don't feel I need it, but looking at the pics, and knowing how it works, it would seem almost impossible for it to be out of alignment. I have no clue why you are having that issue.

The cog belt doesn't have to be tight. Just tighten the eccentric/pulley to put SLIGHT pressure on the belt. Just enough to take the slack out. It needs some room to flex. Too tight and the belt won't last.

Let me see if I have a pic.

Alignment.


Although after running it some, the belt aligned itself back to the backing plate they put on the modded Jack shaft pulley. It's not touching the balancer now.

Tension.

This is almost as loose as I could get it. It looked plenty tight to me.. Spun it to 7200 and the belt is fine. I have about 140 miles on it now.

just installed my 3rd belt tonight...1st one i had as tight..2nd was looser..now the 3rd i tightened the alternator belt b4 setting the cog tension.. i adjusted the cog fairly loose again..i dont think the cog is up to the task..a thought was to install an alternator with a clutch pulley or just scrap the cog and go back to the 8rib...im not sure what to do but i know i cant count on the cog to last

Thanks ajrothm. Exactly the info I needed.

I know how you feel ironhorse. I think it will work once we figure it out.

What was wrong with the 8rib if you don't mind me asking? Why the need to go flip/are you YSI now?

Unreal

Ran straight 8 rib, ran 8 rib flip drive, 10 rib flip drive, and 10 rib with cog. Almost 8k miles now on my cog setup, zero issues. All the others had issues.

I slipped cog belt on, use my hands to rotate the idler just to put a little tension on the belt, not tight at all.

I also said I loved my flip drive right away, but after 3k miles, started to slip, put a new belt on, lasted ok and didn't slip for another 2-3k miles, then would slip again with a/c or turning sharply. Would be out there tightening the belt. Would get to the point where it would squeal on start ups for 10-15 seconds. My flip worked fine with fresh belts, not so much once the belts wore at all. If you have an A&A drive system that would take care of some of those issues for sure since it would auto adjust, but I still don't see it holding 4 rib+ac on a hot day.

Was straight 8 rib ok? Breaking belts there? Why did you go to flip?

realcanuk

I guess I will find out in time. I have about 1000 miles now with no issues. I put a new, slightly stiffer tensioner on the A/C belt..... maybe that will help some.

Xtremespeed

Thanks for the info. That confirms what ajrothm said also. I think too much tension has been my issue. I know it was on the second belt. I thought it was too loose the first go around so I cranked it down the second time. Went back out and found the belt last night and it had holes between every cog almost like there were teeth down the middle of the cog pulley. I'm going to try a very light tension on the 3rd belt. I bet that solves the problem. There just isn't much info out there yet. When I told ECS I didn't have instructions they sent me some for the standard flip drive without the cog so I guess they don't have any yet.

Good luck with that today bud!

Xtremespeed

Thanks man. Might get to it this evening. On base today.

I haven't had any issues with my a&a secondary drive since I put it on, granted I haven't put a ton of miles on it and I have a c5 so I have an extra idler on the a/c... I had my balancer and jackshaft pulley cut for 6 ribs so if the 4 rib setup doesn't hold up I will get a zr1 a/c compressor and switch over to 6 rib

Unreal

Won't hold and slipped like crazy.

Arctic Vette

Sounds good brother, stay vigilant!
