For Lands SAKES! The pulley nut won't budge!

H.G.P. · 06-13-2003, 12:51 PM

I'm using the Pelican pulley wrench, and the wrench on the nut ("lefty loosey" correct?), won't budge!!. And the pulley wrench looks like it may even be warping...What gives???

Must have been tightened too much last time off.
Shouldn't be that hard to do. Use some penetrating oil,
WD40 or one of the others suggested on this board, let
it set a bit and then try again. Use a different wrench...perhaps
a socket and a long rachet, or torque wrench.
Good Luck!

The stock toolkit tools work extremely well!! Of course, I bet you don't have the stock tools.

I just sprayed some Super-Tech lubricant (like W-D I guess), and we'll see what happens, the way it's going, I may need another new pulley wrench!

If you just want to replace the belt, drive it down to the local shop and have them 'zap' it loose for you. You can replace the belt in their lot.

Or just have them zap it loose, tighten it back up to specs, drive back home and do your repairs.

BTW: the only way mine came off was with an impact wrench. I broke the pully hold down tool

I have the same problem. Even though I used a good amount of PB Blaster on the theads, I managed to bend the heck out of my pulley wrench the first time I tried it. I think it bent because the prongs were too long... they acted as levers and the end of the wrench just kind of twisted. Last weekend, I was talking to the PO about the nut and he showed me his wrench and the prongs on it were much shorter... 20mm to be exact. I'm going to cut the prongs down to size and try it again.

I don't want to replace the belt now necessarily, but I'd like to be able to remove it if ever needed in travel or what-not.

The outer part of the pulley itself (the part with the eight holes) seems to be sliding underneath the nut itself, so ironically it seems that it needs tightening?????...yet I cannot loosen it??????

..And the super lub trick has failed so far.......

Still won't budge.......Off to another project....project 102.."How to bend your pulley wrench back to specs".....

According to my car's PO, "zapping" it may break the fan. That's why I haven't taken my impact wrench to it. Yet.

Due to some quirk in nature, torque gradually applied to 250 ft. lbs. does not have the effect as the same amount applied suddenly.

I vote for the impact gun. This method works equally well for front strut nuts, rear axle nuts and lug nuts (in general).

I know this will sound strang but an impact gun can be surprisingly gentle. It hits the fastener with a sharp impact like using a small/light hammer. It isn't the butcher's tool many people think it is. Like any tool you can abuse it. Heck, just because some people use oil filter wrenches to tighten oil filters, it doesn't make oil filter wrenches bad.

I hand tighten oil filter and then go another 1/2 to 3/4 turn with the filter wrench. Is his bad?

PB Blaster is magic stuff. Most auto parts houses sell it.

I just hand tighten my oil filters. Firmly but I can still get them off later with my hands usually (rubber gloves give pretty good grip).

Well, I recall a posting here about a year ago. The guy said the oil filter had fallen off his 964 while his wife had been driving it. She apparently drove home in this condition. He plaintively asked if any harm had been done. I went out to the garage and tightened my filter another half turn.
In the spirit of Talmudic debate, isn't it better to over rather than under-tighten an oil filter? You can always get it off with brute force latter, but if it falls off in flight, you may not notice the trail of oil beind you.

My pulley nut was so tight and at such an angle that the impact would not take it off. I ended up sticking one of the prongs on my forklift into the engine bay and using it to support the spanner wrench, then I put the breaker bar on the nut to finally get it to break loose. Actually bent the pulley before it came off.

I was going to suggest a 1/2" drive breaker bar...but, a FORK LIFT???? Also, another plug for PB Blaster...best penetrating stuff I've ever used.

I think you can get it plenty tight without resorting to a filter wrench to tighten it. I happen to have a 964 manual next to my desk; the instructions for the oil filters are:
"Apply light film of oil to seal on oil filter, install by hand, turning until seal makes contact. Finally, tighten further by approx. 1/2 turn."

Ok so if you tighten oil filters by hand, where did this whole market for oil filter wrenches come from? Surely if you torque them down by hand, the torque required to remove them will be the same.
