Is there a trick to removing fan without taking ac out?

[m962b]

Or do I have to remove that belt? I have searched for and easy way to remove the ac belt, but no luck.

I can't seem to get anything out without hitting the ac belt.

What's the deal?

[m962b]

And can I just cut the darn thing off and put it on later? I've tried adjusting the screws to slide it more towards the fan, but ran out of slack.

Are you having trouble removing the A/C belt to remove the fan? If so, there is a tensioning bolt on the lower left side of the compressor mount if I recall correctly that will slide the compressor and allow you to remove the belt.

[cmonref]

You don't say which setup you have, but surely you can loosen the A/C belt and take it loose, then remove the fan/alternator belt, then remove the fan/alternator. You don't have to remove the A/C compressor -- just loosen the belt. Some setups require you to loosen the belt by moving the compressor mounts, but you still do not have to remove the compressor.

[cabmandone]

I don't see why you can't get enough slack to remove the belt but you could always loosen the mounting bolts for the compressor to give yourself a little more wiggle room rather than cutting your belt.

Tried all of that. I am thinking something wasn't installed properly. I managed to get to it by removing a lot of shroud on the driver side and reaching back to disconnect the wires from the alternator.
Mira been a pain, even though it's supposed to be pretty easy!

On the later Carrera cars, there are four bolts holding down the compressor. You may have to remove the one with the shorter adjustment slot to get it to slide over enough to take the belt off.

Let's assume you have something like a 70-83 911 with a stock factory AC system, the Compressor would be a York. If the compressor was changed you might have a Kuehl, Sanden or Seiko; the later three types of compressors may have an adapter plate attached to them which mounts to either the slider plate '16' or the base plate '13'; Kuehl brand compressors typically have their own adapter plate and slider plate to make the job easier.

To remove the compressor belt (the compressor belt is the belt toward the rear bumper, the narrower belt closer to the engine fan is the "engine fan belt").

Referring to the factory sketch below, you would:

1) Loosen the belt tension nut '14' on the stud that is attached to the ac comp base plate '13'.
2) Loosen the 3 hex head bolts '11' holding down the slider plate '11'; there are two on the front side of the slider plate and one on the back.
3) With the compressor attached to the slider plate tilt the compressor to the left, toward the cooling fan shroud, and slip the belt off the compressor pulley.

To put a belt back on just reverse the instructions.

All the steps above require just a 13 mm box wrench and caution that you don't bang your head on the engine deck lid.

It would help a LOT if you specified which year you car was built. Put the year of car in your signature. It will hep with all future questions. Add your location and you may find Pelicans that live close enough to help you out.

If it is a Carrera and has the OEM compressor just loosen the 4 bolts on the mount plate. It is real easy to slide it over and get the belt off. When you tighten them up be careful not to over-torque them. The torque value is in the manual. It is fairly easy to strip them with to much torque.

Per his Garage link it's a 78

take the 3 bolts out of the compressor. easy. crikey!

Would be nice if this was required when joining PP

My up. 78 with 89,000 miles. All stock everything.

I located all bolts, there are three, then the slide at the end(toward the fan). Still can't get it to move more that 1.5-2cm which won't give enough slack to do anything.

I assume the tension is adjusted by the slider screw (14) once back on?

Although I haven't got it off yet, I was able to get the fan and alternator out with a little shimy-ing.

Btw I am in Stuart, Florida, just north of west palm beach.

Thank you M962B ,

3? hmm, check under the compressor, there should be a 4th nut or bolt. (nevermind above is your diagram)

If like the 3.2, you have two sets of bolts of 4 ( actually under the compressor is a 13MM nut ), one for the mounting of the compressor onto the bracket, then the bracket itself, that us 3.2s use to loosen and slide the compressor over just enough to loosen the belt. Of course loosening the tension bolt. I can not be sure from the diagram if it is bolt 14 or not. Could you post a pic and we can determine where it needs to be loosened.

Yes, if 14 is your tensioner, then that would be the one you tighten but remember 3/8" deflection by pressing at the center of the belt with a medium pressure.

You can use the old VW trick to place carefully a flat head screw driver under the belt and have a helper crank quickly and the belt will pop off. This is a last resort.

I say all stock, but the bearing at least says nashi.... Not very German!

[DRACO A5OG]

LOL, like the Denso compressor :-) or the French Valero Voltage Regulator

Thanks everyone. I got it out. At this point I only confused as to how to tension it back once I replace further down the road.

Trust me-I'm of the new generation. I googles the crapnput of it and have Wayne's book. In fact I have all of his books. Even the one on rebuilding an engine...something I clearly will never do!
