Custom Belt question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

If I'm not running an A/C setup, where do I go or can go to get a custom belt for my application??

A gen IV 5.3 vortec engine has a completely separate belt just for the AC compressor. It can be deleted without affecting the rest of the accessory drive.

I thought the same applied to other LS engines. Maybe not.

All 4 of mine have seperate ac belts

If I'm not using power steering, do I still need the pully installed to make the belt work?
Or can the belt be re-routed without the pully and still be fine?

That may be a diff issue....most I've seen without the psp have the aftermarket accessory drive system...looking at mine I dont see a good way to eliminate the psp with a stock drive setup...the belt comes off the wp and goes around psp and then to alt....theres no direct route from wp to alt without psp...
I know reaper has his setup without psp... but with aftermarket drive on one..

This is the set-up my son Mark (reaper71) did on a 49 Dodge with LS, no power steering and no AC, maybe this is what you need...Jim

P.S. Sorry last pic is unclear. Size is 13/16" X 75 5/8" OC...Jim

Thats what I thought, I got the 76 inch and it was to big by an inch or two...so I picked up a 72" incher and ill let you know if that works?

Thoughts on why the sizes would be different?

Mines an LS 6.0

M-10, 1.50 thread, 160 mm, 82 1/2 belt 5060824 (dayco), 900027A pulley. I used and old tensioner pulley., Cut then little nipple off for a bushing and the above parts

Not trying to start a controversy here, but after looking at the two belt configurations, I noticed the waterpump spin direction on the Reaper truck is opposite of the normal rotation. Can the pump work in both directions?

**mongocanfly** · 08-15-2019, 07:31 AM

its the same lee

LeesTruk · 08-15-2019, 11:17 AM

Yep, you're right. Took a little while to get my head around it. At first glimpse, it looked, well, just wrong

Any pulley that contacts the ribbed side of the belt is turning the same direction as the crank pulley.

Any pulley that is operated by the smooth side is turning the opposite direction.
