No Holes for Fan Belt Pully Wrench

[grizzfan]

I recently picked up a nice old 1973 Porsche 911T with a '76 2.7L CIS engine in it (I haven't checked engine numbers yet). In familiarizing myself with the engine, I refered to Wayne Dempsey's very excellent "101 Projects for Your Porsche 911", Project 3 - Fan Belt Replacement. He calls for a 24mm socket and a pully wrench.

I popped the hood and the nut appears to be 22mm and there is no beveled "super washer" in which to engage the pully wrench. The fan belt engages a normal looking pully that is attached to the 11-fin cooling fan without evidence of shims, that I can see, as discussed and shown in Dempsey's photo. The pully does have 8 holes in its face.

I would upload a photo or two, but the program is not letting me do so.

What have I got here?! Perhaps it takes a different kind of wrench.

Thanks for your help.

Hello fellow 1973 owner:

welcome to the best 911 BBS on earth. How about a picture of your car?

The shims are either between the two pulley halves or under the curved washer that you can see in the picture (BTW, I see at least one shim under the curved washer). In any case, you need to have a total EXACTLY 6 of them in both locations to properly tension the belt and not damage the alternator shaft.

You need two tools to R&R The Fan pulley. A 22 mm (or in some cases a 24) box end wrench and a tool to hold the pulley.

The pulley tool can be purchased here and there are two choices:



Pelican Parts - Product Information: PEL-TOL-P208

or:



Pelican Parts - Product Information: PEL-PW-FPW

You may have one of these (or something similar in your tool bag). Take a look.

If you find a tool that looks like this one:



Pelican Parts - Product Information: PEL-TOL-P209

It will not work.

grizzfan,

Let me second the welcome from Harry to a fellow 73 owner. My 73.5 also has a 76 replacement engine while the original awaits rebuild. It looks like you have the original alternator/pulley for a 73 still on your later engine. Harry's pictures explain what you need to have and the wrench is readily available.

You have found the best place on earth for all things 911. Welcome, and post those car pix asap!

Sheeeesh, anyone that can't figure out the change date for the pully wrench should stick with them Toyota's. Hardly Pelican material.....

[HarryD]

James,

Go easy on the new fellow. While it should be clear, for cars this old, "things happen".

AFAIK, the change to the newer pulley design occured in 1975 and this fellow claims to have a 1976 engine. However, the picture clearly shows a pre-1975 alternator pulley.

I understand the issue since my car is a mostly stock 1973.5 but at some point in it's life, the alternator was changed to a later unit and uses a 24 mm nut instead of the original 22 mm nut. While they changed the nut got larger, my pulley requires the two pin holder not the later single pin holder. Confusing, eh?

[James Brown]

I'm just funnin (hope he sticks around).
I like the older look, cleaner.

[grizzfan]

Gentlemen,

Thanks for the information. I had seen pully wrenches that look like a de-tined comb and that should be the ticket.

Now, as to the untoward Toyota remark, I've owned one of their trucks once but also a Porsche 356SC many years ago. So that ought to make me a Pilgrim impervious to cheap slander!!!

A couple of photos attached. My wife of 47 years and me at Fort Peck Dam on the way back from picking our Porsche up in Canada.

PS: The car runs real good.

... I've seen in a while

As for your claim about "... My wife of 47 years..." , it's my duty to contact the Royal Canadian Mounted Police, and report you as some kind of abuser...

Best Regard

Sorry Canuk buddy. We are a team who enjoy the finer things in life. The Royal Mounties, on the other hand, are a bunch of pussies.

[HarryD]

Nice looking car. While some may feel differently, my car had 15" Cookies for it's street tire until this winter and I do like the look.

[grizzfan]

I found a pully spanner a bit cheaper on eBay from a guy who specializes in Porsche tools and things, slack930. Also bought a jack pad plate from him as well. Thanks for your help. I'll be back!

... that no "pussies" are reading this thread because you probably get the "Latex Glove" treatment next time you cross the 49th Parallel

HarryD,

Per your request here are 7 shots of the trunk area. The carpet in the trunk is very deteriorated and I just pull it out. The hood support is missing and the former owner was using a broom handle. (I'll start looking for one of those someday too.)

On one of the last shots I pulled the canaster away from the battery. Didn't see one in your photos and I really don't know what it is.

I see the makings of rust in the very forward part of the trunk. I'll treat that with some baking soda shortly. I see no evidence of a cross-over battery cable.

[ossiblue]

Grizzfan,

Trunk shots look nice but a bit of soft focus so it's hard to tell but it looks very solid. There is a cross over cable if you look closely at your third picture. The cable is laying along the bottom edge of the wheel well and the end is wrapped in plastic. If you're going to retain the single battery, you may want to really secure that other end and ensure it is thoroughly insulated and secured to prevent any short circuit.

edit: Just saw your other post. Looks like you've got things under control.

[HarryD]

Grizz (until you tell us your real name):

I'll reply in the other thread (Only One Battery), just to keep things together.

HarryD, go easy on James. He's from waterlogged northern Washington, clearly suffering from either premature rusting or being in close proximity to the Canadian border....

I ordered the wrong wrench from pelican. I needed the 2 prong job but received the curved with the one pin.

I did not want to go through the hassle of returning it so,, i made a template, drilled 2 holes into the tool, tapped the holes and screwed in some bolts that are long enough to fit into the holes in the pulley.

if you do not want to drill the one you have use an old wire crimper and drill that is should work.

[James Brown]

both, Jim, both...

[HarryD]

Grizz:

One other thing. Unless you are sure the fluids in your car are fresh and correct for your vehicle, I would change them.

For your oil, you should use a 20W-50 oil that has high levels of ZDDP. While when we were younger, it was pretty true that motor oil is motor oil and the brand really did not matter much, things have changed. Ther is a very, very long thread (Ultimate Motor Oil Thread or Why we hate CJ4/SM oils) on the topic but bottom line is that ther are not many motor oils that are good for our cars anymore.

Two at reasonable prices you may find at your Favorite Local Automotive Parts Store (FLAPS) are Valvoline VR-1 (non synthetic), and Kendall GT. Mobil 1 MOTORCYCLE oil is anther acceptable one and if you look around you may find a supplier of Brad Penn. You can order some of these oils here if you choose. Remember you will need about 10-11 quarts to fill your car.

You want to use a Porsche or Mahle Oil filter (like the one you have now in your car). Others will offer the fitment but there is a history of catatrophic failures of most other brands.

For your transmission, the synchronizers are not the ones found in most other cars and require a slightly less slick lubricant. Kendall dino 80W/90 GL-5 NS-MP gear oil (may be available at your FLAPS) or SWEPCO 201 (you can get that here) are the two products that have proven themselves.

Very McGyver!!

If you are ever stuck somewhere with out the tool, you can also jury rig one with two screwdrivers and a wrench.
