Alternator Pulley Belt issue

[Slant 6 Music]

This is not so much an electrical issue as it is mechanical in nature.

I bought a Tuff Stuff 130 amp Chrysler Alternator. It has a pressed on pulley. Otherwise I would just switch out pulleys with the old alternator (which was replaced at some time). But not sure that would be a fix.

The issue is that the Gates XL alternator belt (7460) I bought doesn't seat all the way in, which causes the belt to slip and squeal and not charge the car. This belt has the traction nubs on the inside of it. Yes, I have the alternator pulled tight. It's not a slack issue.

The old belt I had was some generic one, don't know the mfgr. It had the nubs on the outside of the belt. It is slightly worn, which maybe helps, I don't know. But it sits in there no problem. So I'm using it again.

Can anyone recommend a belt that doesn't have the nubs on the inside. I think maybe the pitch might be slightly different on the Gates belt.

Thanks

Gates belts seem to be hard and that leads to slipping. I like to avoid them.

The real problem is the 130 amps. Why do you feel you need so much? Can the wiring handle that? Are you adding stereo or power drawing accessories?

Is the battery low or is the system wanting lots of amps from this 130 amp alt and the belt can’t keep from slipping with a high demand? A belt rarely slips with zero load on it.

All good questions. Bigger is better I guess. I may be doing those upgrades as well as a voltage limiter board.

slips only when blipping the throttle.

Don't blip the throttle! Unless you drive that way.

Go to an old auto parts store with a crusty counter guy and ask for a low profile belt, it must lye in the grove but not equal in height to grove tops.

Perhaps your old belt was a DAYCO TOP GOG.....the ribs on the OD of the belt were thought to provide greater flexibility over smaller diameter sheaves, like the alternator. Not sure if they're still produced. Go to DAYCO's web site.... www.dayco.com.

I won’t use them belts with the cogs on the inside. Learned that many years ago when working on Oldsmobiles. Top Cog is likely what u had. I like them. Kim

Yes, went to Rock Auto and looked at Dayco (easier to look up) and it's that style, so likely it. But I don't like that look. I'm using the old one for now though. thanks for your help.

440+6...don't blip the throttle? Really?! How will I kick off the high idle?.....

It's not just that. It's slipping enough to not charge.

Actually found a place like that, guy was of no help. I'll find something out there. Thanks.
