So i noticed a slight grind/groaning noise at idle that seemed to come and go while idle rpm stayed dead on 750. pulled the belt and started truck and the sound went away. Alternator is making noise while spun by hand and i also noticed that it seems to have a bearing and one way clutch in the pulley. lots i see online have a pulley that id imagine is keyed on the shaft and held on by a nut. any advise on what you guys think i should go with for an alternator is greatly appreciated! i deleted the passanger side battery and grid heater due to a broken battery box and was having trouble locating a replacement so i went with the cheaper option of deleting the battery as a whole. thanks for your time in advance

Mine is a 2015, my rear barring on the alt was going out.
...
I rebuilt it for less than $100 both barrings, the new clutch pulley and the brushes setup. No tax or shipping charges.
...
I have never rebuilt one, and it was easy, all done hear at the campground on the picnic table. ( Manic electric motors )

The new 220A is good and the pulley is taper fit on almost all alternators

I have an Alt and Starter rebuild kits on the shelf and intend to rebuild.

I rebuilt my HydroBoast for $15.00. After removing the battery, it was a straight forward job. Much better brakes and no leaks.

Good to read that the Alt is an easy rebuild!

Check out nations starter and alternator. Quality builds there. Might be a better option prices wise than a OEM from a newer truck.

 

[steve05ram360]

Iirc my oem off the newer truck was something like $150 including core, which never made it back.

No way! Maybe a cheap crap 3rd party one, but not OEM

 

[s10010001]

Ohh maybe they used to, pre-Biden. Looks like about $400 to the door now. Still not as bad as I thought it would be. Mopar 4801313AC

Mine was off a low mileage truck from local wrecking yard...

Sorry for never getting back with any of you, I appreciate all the information seriously! I definitely got some options here! Definitely sounds like my rear bearing is going on my alternator and am concerned about getting an alternator without the clutched pulley. Heard it stops the belt from squeaking on shut down and I have a built trans that when it shifts I’m concerned the belt may slip on the pulley as well if I don’t end up with a clutched one. Also found my idler pulley above the fan clutch to be roasted. Well the bearing atleast. Looked them up online and they are like 250 for just the bearing. Looks like a bearing out of an idler wheel on a snowmobile. And I can get those for about 10 bucks. Anyone ran into that before? Notice the gap difference where my pick is.

 

[steve05ram360]

Clutched alternator pulley??? Have not heard of that one... Not sure how many miles were on the truck i got mine off of but it has been fine since the install.

How do Clutched Alternator Pulleys Work

Most modern vehicles have clutched or so called one-way or decoupler pulleys. Proper operation of these pulleys is vital to alternator health and the health of other components, especially the ser…

Here’s a good article onthe clutched pulleys

AFAIK, Bosch is OEM for alternator
for stock power needs Rockauto has new Bosch, lifetime warranty.
Also that idler pulley , AFAIK is Dayco OEM RockAuto has them also.

I did not need a new clutch pulley, when i rebuilt mine, but went with one just in case, for the rebuilt alt. It was $42 and i kept the old one with the factory rebuilt alt i did, put in the box of the new rebuilt one i bought. I did have to get a $35 tool to remove/install the pulley. Still all total with tool, pulley, barrings, and the brushes setup, it was just under $100 no shipping or taxes charged.. The Ohriely rebuilt one i got, came with a idler pulley installed, looked new, but who knows.

....
I did belt and idler pulley last year, or bought the stuff and had it done. I got the stuff local at the NAPA hear, the hole idler set up wasnt that expensive. Also kept the old idler pulley and the belt for a spare.

So you mentioned stock power. What if we are making more power than stock?

 

[rghavana]

Not making more engine power,I meant if you need more electrical power ie running power hungry electrical items plow/winch/lights/inverter/amplifiers.
I run DC Power 180 amp for winch/light/radios/inverter
