My original low mile alternator still looks good and works good, but the pulley bearing is going south.
Anybody replace the bearing in one of these?
I wonder if just the bearing are still available?
-
it's a standard bearing. The front one is easy...don't remember if the rear is a bearing or bushing
-
you can order them here if not found locally...we have the early style cs144 which seems to be different on the rear bearing which it does have

and here are pictures from one of my alternators... you can see that the triangular plate retains the front bearing...says I put in a new rear bearing as well

Note to self, scribe case to clock the case on disassembly, paper clip thru the rear housing to hold the brushes in on assembly. Just in case it gets overlooked!!! :cheers:

Thanks pyro!
steve, I see the pn for the rear early style cs144, (# 620004N).
but which one is for the front?
Do I just buy the part #544 kit that has the front and rear for the cs144? That pn doesn't clarify late/early model
-
I don't want to guess wrong so I would call them. If I knew where to look, I probably have one....smh
I posted the number on tbs.com long ago....
Pictures of how to hold the brushes back on the link I gave you if you do the rear

I think its a timken 203ff but here are napa numbers that Gary posted once Here's NAPA #'s: front= 62032RSJ, rear 120A= 60002RSJ, 70/85A= BA608
Autozone lists the timken
-
I just checked, Steve, those are still good #'s and available. Our store actually stocks the front bearing. They don't have anything else, but they have that bearing.
-
I'll be buying one of these, soon.

is the 335-1048 a 140 amp alternator?
-
Cadillac model, I think....not sure which delco it is
-
I need to do some more reading. I'm contemplating a 140 upgrade.
Steve, I'm trying to think of anything electrical I've added to the car:
ramschargers fans with the relays wire upgrade
fuel hot wire kit
couple aftermarket guages
adding a alky kit.
do you see anyneed for a 140 amp upgrade?
-
easy way to tell, if you go full throttle and the voltage drops very much, then you don't have enuf alternator.
At idle voltage should be close to 14 and stay above 13.5 under any condition.
That is reading the voltage at the alternator and not on the scan tool.
If your alternator is tired, then you might as well replace it with a 140....basical ly the same price. the 140 has some minor improvements as it is the second generation CS144

Ir's a '96 Caprice police alternator, and yes, 140A. The smaller 105A Impala unit won't fit.
-
This unit was installed on the following cars:
1996-94 Buick Roadmaster 5.7L, 1996-93 Cadillac Fleetwood Brougham (RWD) 5.7L, 1996-93 Chevrolet Caprice 4.3L& 5.7L, 1996-95 Chevrolet Impala 5.7L, 1995-92 Chevrolet Lumina APV Van 3.8L, 1995-92 Oldsmobile Silhouette 3.8L, and the 1995-92 Pontiac Trans Sport 3.8L
This alternator was also installed on police cars, and fleet vehicles such as taxis where normal operation may include lots of non-moving use with heavy radio traffic.
It is listed as a Lester no. 8112 which may be helpful at wrecking yards, or such places.
-
I don't have alky installed on this car yet, so I can't go out and to a data run and see where it would be at.
I'd like to see what my voltage is doing with that alky pump running.
If that 140amp impala alternator will bolt right up, I have no problem getting one being their only a hundred bucks. and a acdelco at that, although their probably built in mexico.
I would still install new bearings in my stocker and just box and shelf it with its other stock removed parts.
-
gonna continue on with putting in new bearings and monitor for needing more amps if that becomes the case :rock:
-
that is wise. There will be something else that you need more
