lol there haven't been enough threads on this subject yet, so I thought I add my sorry efforts to the pile!

While the engine's out I'm having the engine tin powder coated (turns out my local guy is the same one used by Early 911) and since it's a quick job I thought I have the fan out and see what can be done with that.

1)when I used the three leg puller the fan came off the alternator shaft with the hub/bearing attached, am I safe to use the puller with a block of wood over the hub to press this off?

2)I've run scotch pad over the worse bits on the fan and housing - and it's not much better. Is it safe to sand/grit blast the fan or should I keep going with the abrasive pad?

3)The alternator and duct are currently in one piece - I can't see in any of the threads how they separate - do they?







As ever, any input appreciated.

I can't offer prizes but I can offer a sample of the wisdom and wit of the great Bob Ross

 

Good thread here Alex

Blimey that thread is genius, thanks Gaz

 

So when you starting 'The Doc's Porsche Handbook'?

 

lol, well I reckon the first time I do things I make all the mistake possible, the second time around, maybe half of them, and by the third time I reckon I get it right more often than not, so at my current rate of project completion I should be in a position to write that by 2018

 

I had mine blasted and powder coated, lasted great for years now. Company I use are split between two sights, one in Crawley, the other in Horsham. Take it to either one and they will sort it out.

 

Ok some searching prompted by Gaz's link has lead me to so sensible looking answers for all three q's

1)press that sucker out, whats the worst that can happen, right?
2)something gentle like glass beads should be OK
3)they come apart, there's nothing holding them together but love and oxide - support the duct face down on some wood and gently tap the alternator out.

Cheeky deep link to pelican for an image of that procedure

 

Ahah, so who did you use?

I've been down to Foremost in Newchapel (lovely guy, apparently used by Early 911 amoung others) and I think he'll be able to do glass bead. - my googling also threw up "Colour Coatings" , JR Finishright and "Universal Applied Coatings".

 

In the diary. Right I'm off - I keep polluting your threads!

 

I used universal applied coatings, just off the M23 at Pease Pottage, they are partnered with JR Finishright, or were when I used them for my fan.

 

I sand down the fan by sand paper and painted.
Fan housing is new and also sand by sand paper.

 

I just tapped lightly with a hammer (taken from the Pelican Alt. rebuild thread) and it dropped right out.
The fan hub/bearing was stuck in my fan, but a local Pcar shop used their press and out it came. No charge.
Had the fan, housing and large rear engine tin blasted locally for 30 bucks (well worth it).
Left the fan raw and just sprayed it with a Tectyl type spray, CRC SP-400 corrosion inhibitor (Grainger)
Has an amber color, dries to a hard waxy finish.
No bling, just functional and protected from corrosion
The color of this fan...

 

All done;

Fan glass bead blasted and left raw metal, rough mat finish and is pitted where the corrosion was. I've put ACF50 http://www.acf-50.co.uk/ on it for now. But may spray clear laquer, as the pits will attract filth.

The duct housing is blasted and coated black, as is all the engine tin and bumper brackets while I was at it.

 

Nice....

I'd really like to do my fan housing, its a proper mess

 

Hey Alex,

Top work there fella.

Is the black painted or powder coated? It all looks very nice.

I'd love to get all that done when I have my engine rebuilt. For now I'm just replacing the bumper support brackets.

Carry on.
