Which Pulley Wrench

[kyngfish]

Hello all, so my fan belt isn't squealing, but I have almost an inch and a half to two inches of give and it looks kind of old, so I want to change it. Few questions, I've read through the writeup on Pelican and a few other threads.

• My toolkit doesn't have a pulley wrench and the one that comes up for my 1986 isn't the two pronged spanner type, but the half moon one with a single tooth on the end. I see holes in my pulley, but not on top of the pulley, which is the right wrench?
• I don't see the shims at all, inside or outside of the pulley, should I be able to see them? My current belt is a 710 and seems really loose, but the two halves of the pulley seem to be flush to each other which suggests my shims are all out - shouldn't that make i too tight?

Picture of my pulley below

Cheers,
Martin

Half moon with a single stud, that is what you need

The slots over the belt?

No. The single hole right over the nut you see at 1 o'clock in your photo.

Holy crap, how did I miss that.

martin: re shims -- presume you can't disassemble the pulley without the wrench -- shims between the pulley halves help spread the pulley halves and make the belt looser. If you had no shims, your pulley would be at its tightest possible setting. Shims are pretty small and, if you can't remove the pulley bolt, I'd bet they're hiding behind the bolt.

I'll have a look when I yank it off over the weekend. Just need to get the pulley wrench.

[JJ 911SC]

The shims are hidden by the large keyed washer.

There is six of them and they could be distributed as 3 on each side of the half pulley or 4 in front and 2 behind.

Remember how they are distribute when you take them appart.

Hey all. Thanks for the tips. I guess I won't know until it comes off! 710 is the right size?

[DRACO A5OG]

Yes, 710 is the OEM size but:

Porsche is just under 710MM (3 in 3 out) a real PITA to align the shims due to tightness
Conti Belt is 712-14MM+/- (1 in 5 out)

Adjust as needed.

Martin,this may help when you start. Get a piece of 1x4 lumber about 4 inches long
and place this down on left side below cross member--see photos, then use a good tool set and 15/16 socket ,i have found over the years that the factory 24mm can slip
and give you nasty skinned knuckles. This method you only have to hold one tool at
a time and is very easy.The reverse to tighten.

[kyngfish]

Took me a sec but now I see the wrench pressed up against the block of wood. That's a really good idea actually.

I was going to use a regular socket or breaker but I actually thought the impact wrench might be better? Less twist?

[Chuck.H]

Maybe it's just me, but I don't use a spanner to remove/install the fan belt.

I use an Allen wrench on the alternator spindle and an open end wrench on the nut...

HTH,

I am looking for the wrench pictured. When I click the link I do not see that one. Am I missing it? Any place else I can look to purchase one?
Thanks, Rich

Those 2 links may help
Anyone else's fan belt keep getting loose?
Dealer alternator belt that is way too small/tight? (9.5 x 710)

Martin... If you're pulling fan, suggest putting antiseize on shaft. Makes it much easier to pull fan downstream. There's a woodruff key on alternator shaft---watch for it as fan comes off shaft. Chances are that key will remain in place... also chance it might not.

[Flat6pac]

Put grease on the shims and that will hold them together as you assemble the pulley half.

+1 on the antisieze on reassembly.
