Hi--
I searched around to see if I could find any info on this and cannot---perhaps because maybe its not even called a fan housing? At any rate I have purchased a straight low rust 1971 914 with a spare 2.0 and I intend to have a wack at rebuilding the engine myself. I have all the fi off, engine tin, the alternator, distributer etc BUT I cant seem to get the cover or case for the fan (fan housing?) off. Ive taken off all the slot screws that I can find, and the alternator and I can lightly pull it apart in areas but its still attached. I ordered the rebuild book but its not here yet----and trick to removing the flippin fan housing? thanks!!! (IMG:style_emoticons/default/smile.gif) |

Remove the 4 8mm nuts and washers behind it. Make sure the thermostat wire is disconnected from the connection on the flapper shaft. Pull the shroud off. Done. Have an adult beverage and rest on your laurels while patting yourself on the back. The Cap'n |

There are two dowels between the two halves keeping them together. The dowels run horizontally through the center of the fan (if that makes sense). Just work your way around the perimeter with a screw driver. Give'r a few taps with the rubber mallet too. I just did this a couple days ago. Pete |

You don't need to split it to remove it, the bolt that hold it are behind the fan, so remove it first. If you are going to split it don't forget the two bolts for the bracket for the alternator on the left end of the housing. Gordon

It would be advantageous to have a digital camera handy and post pix of problem areas you will undoubtedly encounter in the future.
Sometimes pix are worth a thousand words (IMG:style_emoticons/default/shades.gif) (IMG:style_emoticons/default/welcome.png) |

Hi thanks for the help you guys--I thought fan may be a key BUT I removed the center bolt and the four bolts around it, but it still won't budge...stuck?

As far as I remember, there are only the 4 studs behind the fan and a bolt through the oil cooler bracket (passenger side) holding the fan housing on (shown in red) (IMG:style_emoticons/default/confused24.gif)
Try tapping it with a rubber mallet ...  |

Remove the fan bolts and as was suggested, try lightly tapping with a rubber mallet on opposing sides to break it free.
Prying could potentially damage the fins. (IMG:style_emoticons/default/smile.gif) |

I would leave the center bolt in, just remove the three holding the fan onto the fan hub. Don't remove the four bolts around the perimeter of the fan.
Once the three bolts near the middle are out (they may be "triple square" bolts that you need the CV Joint tool to remove), just grab the front of the fan where the alternator belt runs, and wiggle it. There is a dowel pin between the fan hub and the fan, and that can help the fan to stick on the hub. Wiggling it for a while will help break that bond and it will come off. Do you have a Haynes manual? If not, get one. It's usually less than $20, and has about 85% of the actual pictures and words from the factory book. It's not a great manual frankly, but it's about as good as we have. Tom Wilson's book on aircooled VW engines is also worth having if you're going to tear the engine down yourself. Here's a link to a Pelican page with an exploded diagram from the factory manuals (also replicated in Haynes) : http://www.pelicanparts.com/914/parts/engi...oling_large.htm In that pic, the fan is #11, and the pulley part of the fan is #12; they are held together by four bolts. The pulley part makes a good handle, so don't remove those bolts if you haven't already. The three bolts that hold the fan onto the hub are #6 (two are not shown). The hub itself and the central bolt holding it onto the crankshaft are not shown in this picture either, but it gives you a reasonable idea what the parts look like. --DD |
