Does anyone know the size or part number for the 2 larger idler pulleys
LBZ: Duel cp3 idler pulley
- Thread starter PIG
- Start date
I got mine from PPE. I couldn't source them anywhere else. There is a pulley for a power stroke that is close but a little smaller diameter wise.
Mine is set up just like the picture and the tensioner is perfect fwiw
Smooth pulley gm # 98057284
grooved pulley gm# 14102597
hope that helped

Thanks guys. the set up in the pic would be a 149" belt?
These are not the OEM pulleys. These are bigger diameter from PPE.
Thanks for the heads up guess I'll have to give Dan a call
Call PPE, they have 2 different setups for their LBZ dual fueler.
Kinda looks like the idler pulley I had to replace on my son's Aurora 3.5 a few weeks ago. Just sayin'......
So ppe's website has an install PDF for lbz/lmm that shows 1 pulley...this is the way mine is set up..I ended up having to replace that pulley(it's the larger pulley below the ac compressor) w/ a 100mm gates pulley from Napa part # 38002...
There is a gates idler pulley that you can use. I don't remember the part number, but you can Google and find a chart. The only thing you won't get is the fancy spacer PPE gives you with the dual cp3 kit. I want to say the one you want is 90 mm OD.
Thanks is guys
Bringing this back up from the dead for future reference:
Pulley: Gates or AC Delco part #38002 is the 100mm pulley that PPE uses, it has a 17mm ID bearing
ATI Products spacer part number 915993 will space it .35" and bush it down for the 10mm bolt like the PPE spacer
Or you can use Gates part # 91051-15 bushing to bush it to 10mm and a spacer to get the correct offset.
Or you can use an LML shouldered bolt part #11515769 so no bushing is required, but you would still need a spacer to correct offset.
I need 2 of these setups for the belt driven air compressor setup on my LMM and am going to use the ATI spacer and the LML bolt so the bearing is basically bushed on both ends. To play with belt tension you can find larger and smaller diameter idler pulleys on the Gates site and most are 17mm ID bearing. Gates 36299 is 90mm OD and comes with a spacer and bolt that I think will bolt right up and work.
