Alternator pulley and crank pulley do NOT align. Fix?

[alexvw]

I bought this aftermarket internally regulated alternator and the pulley is not lining up with the crank pulley. I know there is a fix to this because a lot of guys are running them. Do I move whole fan shroud assembly back somehow, or shim the crank pulley? Help!

Loosen the strap and shove the fan shroud back or forth till it lines up. Then tighten the strap.

Will give it a try, do I need to loosen the two bolts securing the fan shroud to the cooling tins?

Was able to move the shroud back but the pulley is still off by 1/8 of an inch. I heard that it was important that these pulleys be inline so the belt doesnt wear as fast or put too much stress on the alternator bearing. Is this true or will I be ok with 1/8" between the pulleys not aligning? If not, are there crank pulley shims, or will I have to start mangling up the cooling tins..?

get an alternator backing plate

went to shop
put alternator and such next to the generator equivalent
standing on Ends they were the Same height

i swapped the backing plate
put it all back together
set them up on end
Alternator was 1/4" shorter than the generator


they didnt look Too Different
But i Assure You they are different

been there done that..
In Fact 2 different people here in Vegas are wanting me to do there conversion
stand and plate and all

If you get/got the "single wire" alternator
then It Is INTERNALLY Regulated

take 3 Fat Red Wires off VR and Connect them
(i took sheet metal and cut a 3 prong flower out of it for them)

and connect the Blue and Green at VR

...Eliminating the VR

you are posting many post on the same topic
why?
http://www.thesamba.com/vw/forum/viewtopic.php?p=6037079&highlight=#6037079

do you expect us to read them all just to find your car , mods and story?
really?

ever vw is a story but all we have is one photo
is this photo before or after changes.
hello i have a 74sb
its not stock and has the following non stock items on the car
or show very close picture sets of problems so people can see
it and people with trained eyes can ID wrong parts.
its free, just get a cell phone (new) or a real cam.

first off what started, this event
do you have more than one post on your alternator?
Examples.

my car has a gen.? really a real generator and then just started a swap?
no?
my car has a stock alternator 74SB , some times they do...did yours?
i decided to change my stock alternator to a new type.
or my stock alternator took a crap, so wanted to up grade, to higher amps.
is that true.

what i the full story.

tell the full story and I promise answer get way better.


not all cars are still stock, in fact, dang few. Yes , many think so but they are in fact wrong, most of the time.
and in fact ,they post picture after long worthless posts and finially
the truth happens. like where did you get that part....etc.....


you need to show photos
i have stock 74 sb
here is photo
then i removed the Alt.
i then bought this alt
i stuck here, so here is the place im stuck show a photo.

that way works best. parts assembly is a very visual process.
and you failed to buy the book or say where in said book you fail at.
so photos man. lots of photos.

Can you describe exactly how they are out of alignment? Is the alternator pulley further back (towards the rear of the car) than the crank pulley, or is it the other way?

Are you running a stock crank and alt pulley, our some chrome or billet aftermarket one?

Is your alternator part of an upgrade kit, or original?

Is there a spacer between the alt pulley halves and the alternator itself? I'm not referring to the 10 shims you should already have.

ashman
he had many damaged parts,
the photo , he never said, but i thing the photo above, is the before it blew up
he had many parts damaged
fan and other parts.
fact 2 the new fan, slides it shaft inside back and forth.
his new alternator is no good, the shaft move axially 1/2" he said.
just sitting on the bench it does that.

i think.
no photos. of the new parts, sadly.

he has not discovered, Gallery had photo ,yet. above.

The problem here was the inner pulley half and the new (bad) alt. The alt yet again wasnt designed right so the pulley couldnt sit flush on the shaft. I ended up grinding the back of it and it worked. Dont worry though my new alt kit from airhead parts came with new stand, strap, shims, pulleys, belt, backing plates, new 36 mm doghouse cooling fan, hub kit, and 75amp alt. They had a vid on youtube that showed them assembling it with part #s and i ordered every part # to make sure it will work. I should be seeing it today or soon

See how the belt is at a diagonal? Will this be ok? The shroud is pushed back as far as it goes..

nope!!

wrong backing plate a assure you
i had this very same issue

took gen/plate/fan and an alt/plate/fan
standing on end on counter they were same height
(backing plates Looked same)
took apart and switched JUST the 3 pieces of the backing plate

and when they were back together and sitting on the counter again
the alternator was about 1/4" shorter
BAM.. Never had the problem again

I bought the whole kit, and the backing plates were included.. Should I switch to OG plates?

i would switch backing plates and take a measurement of the height sitting on end on the counter before you tighten the main fan bolt down

if you happen to Cant get it off you can reach behind it while its in the shroud and do it as if you were taking the pulley nut off

why not send that picture to the guy who sold you those parts.
that way , the problem might get solved for everyone.
wrong Alt
wrong fan housing
wrong fan housing base plates.
if you had your old working gen,. you could measure these offsets on the old gen (alt) and see if it was the gen , in 5min work. with a steel ruler.


where is the old Alternator?
measure the total lenght of the Alt. shaft
then the off set from the rear of said shaft to the rear Alt main flange.
(the flange that is part of the alt)

before installing any ALT. it is best to set the housing down, on block tins.
then set the ALT INTO house, with tin flanges, attached, hand tighten nuts.
then lay the ALT down on the gen stand at same time as above , line.
last eye ball that alignment posted ? then do the install. if this pre test passes. (i never trust that it just fits. not on relic VW's)

all parts must match here.
1: housing to cylinder tins.
2: mounts
3: Alternator.
3 ways to mess up. sorry yours does not fit.

Hard to help with few facts: PHOTOS (after all we cant magically see p./n on any of those parts)
1: engine photos. with fan housing removed. and gen stand.
2: back of fan housing. front and rear.
3: photo of both the old and new ALTernator, naked, (neat)
4: what parts are OG and which are not , is a big clue. (endless story that)

lacking photos or p/n it is vary hard to help you, we are not there, nor can we SEE or touch it or take measurements.


how i solve these types of problems.
1: measurements.
2: and i look up all the parts 1 by 1 to see the differences.. by year.
so i can ID each part by eyeball. (there are vast photos in the Gallery to do that.)
FWIW:
my guess, is that the non Alt parts, were from a different motor
or the motor in the car is from a year, that didnt come in you car new.
ie: motor year S;N dont match body and pan year S/N.
why is that so important? well , you tell the parts seller the body year
and get the wrong parts, that is why.

I measured my aftermarket alternator to OG alternator. They both are the same, shaft, body etc, if not they are different by a very tiny bit..



The backing plates are a different story. I lined my aftermarket one up to my original one and the OG one appears actually a little taller than the aftermarket one.. Yet the pulley is still not lined up with I switch back to the OG plate.. With the aftermarket plate on it seems slightly pushed back which is what I want.


The OG one is the silver one, the aftermarket is the black. Hope you can see it that was the best I could do. OG looks taller by 1/8"

The shroud is pushed all the way back.. what else can I do? My crank pulley also appears slightly bent(maybe bent in? I remember prying gently on it when checking end play when rebuilding the motor.. But I just looked at it and spun the crank around looking down the sights of the other pulley and there was no change.) Something is pushing it out.. WHY??

Is this that big of a deal? Why has no one else had this problem with theirs!!

when i say backing plate i am taking about All 3 Pieces

Not just one piece


and I Have TO Ask...cuz i have seen it

Are the cylinder tins on the right sides?

Might be a silly question but you ARE using an alternator stand and not a generator stand, right?


My guess would be you are too close getting both pulleys lined up to NOT be using a alternator stand... but could there be something between the rear facing lip of the stand and the wide part of the alternator body? I'm pretty sure the alternator is supposed to be pushed forwards (towards the front of the car) until the wide portion hits the stand. If you are not butting up against the stand, find out why?

3 parts (and a ruler)
1 or all are wrong
the plate (wrong)
the gen (correct you said)
the stand, but the stand is adjustable, so if it slides forward, the gen on stand
and the gen dont hit the stand , then its not the stand. it's the plate.

how did you mix up the parts, i forget, was it damaged.?
you are the guy with the destroyed plate. (fan housing plate)
IIRC

it's not:
wrong motor casing.
not wrong fan housing, dog house or none?
or aftermarket junk fan housing?
only you can ID each part, and see what year it came from and what motor.

and is not easy, unless you post photo of a parts.

inventory.
what engine (DP ,SP, year>? what?)
what fan housing (oem, clone, what?)Dog, or no DOG. year?
what fan plate to gen. (big suspect but?)
what pulley is that ,on the engine crank, it's not stock, not at all.
what gen (seems ok in photo)
gen stand, should be ok, if last ALT was OK.


what is pushing it out, well , you didnt show a photo from the right side
of the gen stand, so, how can the CLOUD guy say?
is the gen hitting the stand on the rear side of stand.
Yes, , wrong gen, and or wrong stand.
NO, then then fan housing is Stopping it, obvious right?
only 2 things can stop that, !

the stand, or the housing.
only you know this fact, not us, no photos yet.
nor can i see that blurry crank pulley, WHAT IS THAT THING?
the displacement is possible 2 ways.
THAT PULLEY or the GEN position. one or both.
start with a stock pulley then work the GEN.

all these aftermarket parts, never were ment to fit together....
only OG parts fit, together, baring that, its your private lil hell.
but we can show the way, once each part is Identified.
and has not been yet.

sick
i see these 2 guys in China, one EAst and one west , and never met.
get it? Dark Humor. I feel your pain.

Shroud is original to the car, alt is the same as og, the stand came with the alternator kit so it is the correct stand, the tins are aftermarket chrome ones because my original where all bent and rusting through. All og backing plates are put on it, i will look at the stand to see if the back is hitting it. Im thinking it might be the crank pulley causing this if all of these alternator problems are checking ok. It is in aftermarket degree pulley with the 4 big holes in it. Should I i try the original pulley?
