YIKES... NOT MUCH HOLDING THE FAN - 1500 FAN HOLE..
68AutoBug - February 18th, 2012 at 01:44 PM
Took My 1500 fan off My alternator to replace it with a doghouse fan found nearly a round hole.... YIKES
just lucky I guess..
wouldn't have been long before it started to spin depending on the tightness of the nut..

drugs are bad!

Hey Lee, what type of paint did you use for your fan shroud? Heat resistant or just normal spray paint?
Camo - February 18th, 2012 at 08:01 PM
Lee,
just another tip, I think the fan goes in the other way around

vlad01 - February 18th, 2012 at 09:50 PM
Arrhh! its too yellow! 
"puts on welding mask"

Hi Lee
Make sure you have enough shims under it otherwise the nut will bottom out.
I think the paint fumes are affecting your judgement, what wrong with black?

I normally use heat proof VHT paint .. which isn't very shiney
I then use clear VHT over the top of it...
this time I have used killrust EPOXY spray paint...
I just sanded down the fan shroud, but the tinware over the heads etc I have taken all the paint off...
this paint then needs no undercoat its self primiing..
It has no heat rating but its an excellent paint... very glossy..
takes about 6 hours to dry...
I'm hoping it won't peel off... lol..
cheers

Mr Henry ford liked black... lol I like Yellow now... lol
Steve...
I had to take My alternator 30klms to get My Son to take the old fan off the alternator and install the new one..
BUT
I forgot to take the heavy waved spring washer with Me...
the old fan did NOT have that washer but did have shims..
this fan had 2 or 3 shims on it so WE left them there..
rattle gunned the nut on with locktite...
so, I don't think it will come loose..
but will it be OK without that BIG waved washer??
I thought the shims were just for aligning the fan??

Make sure the fan has NO PAINT on it........otherwise the flats on the centre hole may 'flog out'.
cb john - February 19th, 2012 at 11:55 AM
Lee, you need to arrange shims the way, that you have 2.0 mm gap between the fan and the fan cover...the lock washer is necessary..
it seems, that there is no workshop manual in your posession..
ragged - February 19th, 2012 at 01:24 PM
Yes thats all fine, but what colour is the nut? Red would have to be the go!
Cheers Dave
1303Steve - February 19th, 2012 at 01:30 PM
Hi Lee
That fan nut only needs to be tightened to 40-47 ft.lb, don't know why you would need a rattle gun for that. The paint on the fan could also affect
the balance.

My Son thought it was a new fan... nice flat black
and oddly enough I left it that way...

Hi Steve
My Son has had problems taking these nuts off... and I searched at Home but I couldn't find the 36mm socket...
My Son assures Me I have one... and he also has one but couldn't find it.. so We went to His work workshop and used their socket and rattle gun to
get the old fan off.. and naturally used it to put the new fan back on.. He said he snapped a shaft off once using a rattle gun on these so He
didn't use much pressure but also used locktite..
It had NO waved heavy washer on it and I had forgotten to take another one with a nice yellow nut.. lol
so its got a black nut and the shims that were under the old nut... I know its not going to come loose.. but do you think there is enough pressure
there to stop any problems with the fan moving?
I have heard of people actually welding the nut on...??
cheers
LEE
pic of the ones I left at home... notice very thin coating of paint on the washer..

the Nut should have been yellow but as I left it at home
[30 klms away] I reused the flat black one... lol

HappyDaze - February 19th, 2012 at 04:00 PM
That's a worry, Lee. Can't remember EVER leaving my nuts at home.....but I'm sure I wouldn't have got 30km before realising.
helbus - February 19th, 2012 at 05:25 PM
I would worry if I had a black nut, however I would be very concerned if I had a yellow nut.

don't paint your nuts or washers or the surface they bolt to
for the matter of fact.
I learned last time from that mistake. They come loose every time guaranteed, extra espesially for epoxy paint!
Klaus - February 22nd, 2012 at 07:29 PM
next time u paint your nuts use an elastic band around them tight so there is good definition between them and the shaft , a little baby oil on the
shaft stops the paint sticking and reduces friction
68AutoBug - February 22nd, 2012 at 07:40 PM
I usually take all paint off flat washers and nuts and surfaces before tightening..
then I paint them...
I let the paint run into the threads and have never had one come off...
I used to have some loctite called after lock and You put it on after the nut... it ran into the thread and locked it...

You said it bob, that's a really good idea klaus, some baby oil will also help lube the shaft as well, so when its inserted an screwed in hard, you
shouldnt get too much friction on it an break ur shaft if it's tight.
HappyDaze - February 23rd, 2012 at 07:11 AM
Some good advice here. One good lesson to be learned, though.......NEVER leave home without your NUTS!

would You take the black one or the yellow one??
or both..!!
Lee
I believe many non mechanic people forget that when tightening a bolt or nut etc that having the thread lubricated the bolt or nut will go on tighter
do to less friction...
especially if using a rattle gun or torque wrench...
LEE
vlad01 - February 23rd, 2012 at 02:52 PM
The black ones are no good as they have taken a bad beating and the yellow ones are Chinese.
D-train - February 23rd, 2012 at 05:28 PM
Lee, do u have a special lube u use for less friction? Do u also find if u don't use any, does it make it harder to screw it in?
Klaus - February 23rd, 2012 at 05:42 PM
well see mr d-train i was talking to an older mechanic today describing the problem with lee's rear oriface flogging out and he highley recommended
lube but a waterbased one as this would ensure there was no galling on nuts or shaft , he also mentioned that whenever a vw related oriface was
flogged out or looked sus they would have to contact a gentlemn at vw by the name of Colin ..ahh what was his last name something polish or eastern
european ??? Oskapi thats it , he said weird guy only little and would introduce himself really quickly saying his first and surname together, the
previous guy was a bit of a dick and was huge and the guys didnt like the thought of his huge hands near the oriface problem, Some of you older guys
might remember him said he was pretty busy in surrey hills and oxford st mechanics , oh i found out the proper name of the elastic band thing to its
a rooster ring he said best way to fit it so there was definition was to use someone with clean hands to hold the offending nut/shaft and get it as
close to the nut/shaft meeting surface , then lubricate liberally on the parts not wanting to be painted ..hope this lets u know that your not the
only one to have a flogged out hole
