U still broke the rule, rule is counter clock wise, smooth/smooth, groove/groove

Did you look at his pic...he has smooth/smooth, groove/groove. The red lines below show how the belt was installed. And you did not say count wise before just "just remember the belt goes smooth side to smooth pully, ribs go on ribs ".

so I forgot one piece, sorry. NOT the first time I said this on this site...……………...

I have taught this at many shops, its so easy once see it.

ALSO U all missed why the idler was there in the fist place...………..TRACTION for the A/C

The way it was installed the a/c would slip

 

[trippytro]

Yeah it turns out chally is right, both setups “make sense” however, two ribbed sides were floating up against each other and under load it would heat up and rip itself apart due too too much/little slack. Problem solved folks thanks!

Dude, the AC is on the other, bottom side and routed properly. The idler in question is for the alternator...look at the picture.

wrong way never made sense ever

WELL still a traction issue, NEVER used a diagram on a hemi ever, never needed it.

Yeah but it goes to show even following the rule can lead to incorrect routing. If that pulley was about 1/4-1/2" smaller in diameter so the ribs would not rub I wonder if it would run without issue?

I was on the think tank team in 2011 in a small town in MT shop that had a issue finding routing diagrams.

Took me to think out side the box to come up with this, sorry U see it does not work.

Was only to share what I learned after installing many a belt AFTER somebody took the belt off. So NEVER SEEN the routing to prove my way works.

So not sharing anymore

Get back in your think tank, jeez

That technique has been known for years proceeding you and me, but it goes to show there always exceptions. Thanks for sharing

Wrenched for years, no one told me the rule.

And U still put it on wrong???? Confused...……..

Don’t be , you got years on me congrats. We’re still here on a forum to share info and learn, clearly you’re here for something else?

I did not mean to get you upset, my point was you could still route the belt the wrong way using the rule of thumb. I have placed the belt on wrong like Trippytro (in fact that idler alwalys stumps me for a second) and was like "that can't be right" so I looked at the diagram (don't recall if there is one under the hood like automakers used to do) to confirm. Rule's of thumb work in a pinch but always best to confirm the routing...especially when all you have to say is "OK google find me the belt diagram for a ...." on your phone.

All I can say is this issue was definitely trippy......bahzingah!

Funny thing. My owners manual has no interval to change the belt. I have 23,500 miles after 4 years.

Old school was to change every 30,000 miles.

I'll stick with old school and change it at 30,000.

 

[Unicorn]

LOOSE rule is around 100K miles or cracks whichever comes first.

Have 98K 2013 Ram OEM belt still measures and checks out fine

Hi guys. I need help ))
I can not find the original part number alternator pulley for 5.7 hemi 2015+
This is number 5 on the diagram

 

[ChallyTatum]

I've checked mopar sites and it does not show it separately.

Other sites show the decoupler pulley but my 2015 RT+ came with the plain pulley (shown in bottom alternator of image obtained from summit).

Which I believe is this pulley, which seems to have similar dimensions to my pulley, although I cannot verify the 10mm offset with the pulley still on the alternator. However with these dimensions you can check to see if it will work on your alternator. The decoupling pulleys are ridiculously priced and not sure if they are swappable on alternators that did not come with them originally.

NOPE, I RE-LOOKED and U still broke the rule. U had TWO belts on one pulley. Which cause less belt wrap which is also easy to see.I see this when a person take it off and not look at the routing on it.
Belt wrap confuses everyone.................

Anytime u see less wrap on the pully U have it on wrong.

You mean the same belt would be touching the same pulley twice, BUT it is not. There is still just enough clearance between the belt in that area where it won't rub at low speeds but as soon as you put an unstable load/speed it can rub.

For those changing the Serpentine belt

Well....heres how my “preventive maintenance” went Changed plugs and belt on Saturday. Noticed the idler was rough and noisy so i grabbed a new one. 24 hours later, shredded a rib off the new belt. Changed the belt AGAIN , and another 24 hours later she completely destroyed the belt this time...

Ah but it does hit the water pump pulley twice...you win.
