like it says i need a good crank pulley for my escort, its an 86 - 1.9, i replaced the head and had the pulley off , while off i noticed it was cracked in a bunch of places, is this common on these pulleys? anyway if anybody has one let me know, i tack welded mine back up before i put it back on but man it makes an awful squekin noise now its very annoying! thanks guys -mike.d

UnexplodedCow is buying the one I have. I9 never had any problems with the pulleys. You might need to specify rather you have a 5 rib or 6 rib pulley.

ok, not sure about the alternator belt, but i know the power steering belt was 4 rib, does that make any difference or were they all 4 rib? oh and the squeaking noise i was talking about in my original post is not the belt slipping , its the actual pulley making noise , flexing i suppose

 

[marshpoprock]

There are the 5 rib and 6 rib pulleys used on these cars. If you have factory air, most likley you would have the 6 rib. The p/s doesn't matter. The pony I just parted had a dealer installed a/c with no p/s but had the grooves for the p/s belt.

 

[UnexplodedCow]

The power steering is a 4 rib, and the alternator is 5 or 6 depending on model. I think the higher output ones had 6 rib..but a 5 rib belt will do just fine.

I had the same type of problem with my main pulley. It got all wobbly and the edges started cracking off. I don't think it's very common, as you're the second person I've heard of (beside myself) with an issue. If I had the box of pulleys around, I'd sell one, but I still haven't found it...and pretty much thing it's gone.

this might help. We have an 86 ho motor out of an exp and the bottom pulley is just a pulley. On our 89 gt with the ho motor the bottom pulley is a harmonic balancer. Is yours just a pulley or combination pulley/balancer?

 

[UnexplodedCow]

Good question that. Mine was a damper type. I've been looking for a non-damper kind since they would be more reliable...no rubber to deteriorate. Other than that my pulley is cast iron, but isn't very strong on the edges apparently, since it's cracked off in three different spots.

this pulley is just a pulley and the alternator is a 5 rib this thing has gotten worse and making more noise i took the alt, belt off tonight when i got home and the whole outside pulley is completely loose probably better not drive it any more till i find a pulley, i'm afraid it will desinagrate and possibly take out the radiator, that would suck! so if anybody has one i still need one, thanks mike

 

[UnexplodedCow]

Are you sure the crank bolt is torqued down?

 

[89fiveohman]

yeah its still tight i even put it on with my impact! its weird you can feel down there inside the pulley and the cracks that run from the center out are now completly broke and they let the outside pulley just kind of dance around

 

[UnexplodedCow]

I'm guessing you drilled a hole in the chassis to fit the socket through for that. It almost sounds like a damper style pulley....pictures of it would definitely help. I'd definitely say it's a strange case. I haven't exactly heard of the damper ones falling apart either. Once the new one is on I'll post pics of the old one.

 

[89fiveohman]

no , no holes drilled just let the motor down far enough to get to the bolt, i dont think this pulley would be a harmonic dampner its very light and no rubber in it, its all metal what are some of the obvious differences in the to pulleys, i know in my small block ford v8's the harmonic balencer is heavy and the outer ring is in place with a rubber ring, are these pulleys similar to that

 

[UnexplodedCow]

The only way to tell if it's a damper is to look at the back of it, and there will be a little circle of rubber that's visible.

 

[89fiveohman]

ok, i plan on pulling it back off one evening this week, then i will be able to tell, and i will try and post some pics of it so you can see what has happened to it
