Porsche-man Posted 12June, 2018 Report Share Posted 12June, 2018 Would anyone have a fan housing to suit a 911SC engine, as I discovered a crack in mine today. Thanks Link to comment Share on other sites More sharing options...
Stew F Posted 13June, 2018 Report Share Posted 13June, 2018 If that's the only crack, or there's a few small ones like it, that's an easy repair for a specialist welder. A little bit of filing and sanding afterwards, and it will be as good as new. It'll probably be cheaper than some of the stupid prices I saw for crusty 2nd hand, often damaged, ones. Fortunately, @MFX came to my rescue and sold me one for a sensible price. What year is your SC? You can buy new housings from Carpoint in Germany for $700 plus freight. But if you have a 77/78 SC with a 226 mm fan, you'll need a new 245 mm hybrid impeller to go with the new housing. Another $500 (European Parts Service in the US of A). Mine had cracks so big you could put a 5 cent piece in them, and the welder said he could fix it, but couldn't give me a quote. Dress out the crack, preheat, weld, slow cool. Continue. Whatever you end up doing, check it for roundness, and don't over tighten the strap. Link to comment Share on other sites More sharing options...
Scott930 Posted 13June, 2018 Report Share Posted 13June, 2018 I just had my alternator overhauled and in process a couple of small cracks in housing were noticed. It was sent off to repair/weld (not sure to who, unfortunately, as mechanic sent to someone they use for things like this).. cost = $210. Link to comment Share on other sites More sharing options...
Gavn Posted 13June, 2018 Report Share Posted 13June, 2018 I've had one welded in the past but was told at the time to start looking for another replacement..... Link to comment Share on other sites More sharing options...
Porsche-man Posted 13June, 2018 Author Report Share Posted 13June, 2018 @Stew F Thanks for your detailed response. It looks like repairing the fan housing might be an option. I guess we could always try that first, and then if it fails, buy a new one from overseas. Link to comment Share on other sites More sharing options...
Peter M Posted 13June, 2018 Report Share Posted 13June, 2018 I actually came a cross a post on Pelican Forum recently that Brian from M&K Exhaust fame actually repairs them successfully and has done lots. Having been impressed with the workmanship of their exhausts I would at least send Brian a email and photo for a quote. http://forums.pelicanparts.com/porsche-911-technical-forum/980667-fan-fan-housing-cracked-options.html Link to comment Share on other sites More sharing options...
