Cold Air Blower Motor

[Guest]

Afraid after months of making nasty noises, mine omitted a deathly smell of fried electrics and finally died. Anyway, with summer approaching and the (hoped) requirement of needing to have fresh air blown into the cabin, I thought I'd better fix the problem. I now have the offending piece of German hardware out and removed from its housing which leads me to my current problem. I can buy a new motor excluding fan from Type 911 for about £60.00 or a new motor with the fan on the motor spindle for about £120.00 - guess which option I'd prefer. Unfortunately, I can't seem to split the plastic fan from the motor's spindle. I've tried the hammer option but this failed. Has anybody previous expierence of doing this job succesfully without cracking the plastic fan?

Thanks Zhan. I shall persevere with the wire brush tonight as like yours, the motor's shaft is quite rusty. Nothing to loose I guess by vigorous use of my hammer....

When I did mine, I pushed the fan further onto the spindle first, then cleaned and lubricated it before pulling the fan back off.

If you knacker the fan I have spare one somewhere. You'd still need to remove the old motor from it, but hopefully by then you will have the knack. []

Thats great thanks, I will let you know. Just concerned now that the new motors spindle will not be a tight fit in the soon to be battered old fan. Thanks for your advise and your offer Nige.

Hi. If your certain that its the cold air blower thats gone then you have some under bonnet (boot lid) work to do: Remove your boot carpet. Remove the 4 bolts that hold the shaped cardboard cover in place that shrouds the bulkhead. Now you'll see the black plastic housing with two plastic pipes (approx 10cms diameter) connected. Remove the 2 jubilee clips holding the pipes to the hosuing and pul them free. Remove the electric plug in the bottom of the housing. Remove the cable that opens and closes the internal flaps - this is the look alike bike brake cable. Just undo the nut on the very end and remove the clip that holds it in place. Remove the 2 bolts at 4 oclock and 10 oclock and the entire housing comes free. To get the motor out you need to remove the 6 steel circular clips around the housing and it then splits in two. Thats the easy part - now you have to split your fan from the motor spindle which is where I'm at..... Good luck!

Warm the plastic fan with a hairdryer or hot air blower first over the spindle, hold the unit betwwen you kness and pull both sides of the fan blades up, this makes it much easier.

I couldn't get mine off after days of soaking in WD40, pulling, leavering etc. I ended up dropping mine while I was fiddling with it and cracked the fan blades on the kitchen floor. Bought a second hand fan from Tuthills while I was there getting the motor. They showed me the heat trick and it worked striaght away for getting it off and on again.

Thanks. Sounds rather more sensible than my usual brute force method. MOT day tomorrow morning and then this will be my afternoon job. Thanks again.

Greetings
I had the same fun and games when I did mine a year or two ago[] In trying to get the &*^%*+ fan off I must have distorted the hole slightly so when I managed to get it pushed onto the new motor it f----- wobbled. B-------s Never mind [:'(]
I ended up buying the complete unit in the end []
I didn't know about the hot air trick, my Mum never mentioned it to me, anyway good luck.

Done and dusted! The hairdryer trick worked a treat. All went back together nice and easy. One job down, just my oil pressure sender unit to go....

Nice one

Easy when you know how, shame I didn't know how before breaking mine!
