So I'm still trying to replace the belts on my car and I'm now to the point where I think I'm ready to put the belts on. However, I was just out there looking at the crank pulley and while most pictures show the engine having the two bigger rings on the inside and the smaller ring on the outside, my engine has the smaller ring on the inside and the two bigger rings on the outside. Additionally, the inner ring seems to be covered in rubber. I'm not sure what the hell is going on. I know the belts were pretty messed up so I'm guessing that the rubber melted onto the inner ring but I'm still not sure why the smallest ring is on the inside.

Note: There's no belt on the crank pulley in this picture. The inner ring is coated in some sort of rubber. I don't know if it's melted belt or what.

 

It would certainly help if you gave the make, model, engine, and year of your vehicle.

 

Sorry. 1998 Acura Integra LS. It's the stock engine.

 

I'm just trying to figure this out. The belts went on Monday and I've been running into a ton of issues (bolts breaking off on the alternator), bolts on the engine torque mount breaking off in the frame, etc. and I'm now on day three with no real progress on something that should've taken an hour to do. My coworkers are starting to get pissed about having to take me to and from work.

 

Looks like the pulley is on backwards, no wonder your having problems.

The smaller, [outside] pulley is for the P/S pump, the inner bigger one is for the alt., the bigger "center" one is not used, unless you have AC, [AC compressor]. 94

 

It's been this way for years so I guess I'm just going to live with it. Haven't had any issues so far.

What about the rubber on there? Is it possible that it's the wrong pulley and that's supposed to be there? I don't want to tear into it and try and remove it before I'm sure it isn't supposed to be there.

 

I do not see how the pulleys on the alt. and P/S pump line up, or if they do then the alt. is under-driven and the P/S pump is over-driven, not good for either. 94

 

So I sliced off a small portion of that rubber pulley and it seems like it's flat all the way across. Hmmm.

I'm not disagreeing that it might not be ideal but apparently (after talking to the previous owners) it's been this way for the last four years. Even if it was the other way, what's the deal with the rubber coating on the one pulley?

 

You're never going to believe this.

See the two big pulleys? See how they're kind of crooked? Well, the two big pulleys slid off that rubber piece towards the edge of the car. I took a rubber mallet and hit the two big pulleys a few times and they slid over revealing the small pulley exactly where it should be.

 

Welp. I was just messing around and I think the crank pulley is shot. I moved the two bigger pulleys over and they now spin freely (not connected to the crank pulley anymore).

 

that pulley is definetly not stock for a 98 LS

Wow, It did look backwards but yeah I see waht you mean, the two bigger pulleys slid over the smaller one and revealed the rubber.

Yeah time for a new crank pulley, dude that is one ****ed up crank pulley. Get some pics when you rip it off and show us the damage. I guess honda spot welds their crank pulleys or something ha ha ha

 

are any of your accessories seized, alt, ps or AC. thats a weird break maybe belts too tight and something seized up. I wonder if the stock pulley was modified in anyway for it to break like this

 

Everything turns smoothly.

Apparently the pulley is stock. They're made with a layer of rubber that's used to absorb vibrations. Apparently that rubber layer dried out and separated from the two large crank pulleys and then they must have slid over the smaller pulley. If I push the two bigger pulleys towards the engine, it looks just like a stock Honda crank pulley.

At this point I'm going to let my local mechanic deal with it. It's already been four days of work and I'm tired of messing with it. Plus, the crank bolt is a huge PITA and I'd much rather let them blast it off with an impact than waste time trying to get a new crank pulley and then spending 5 hours trying to get the crank bolt off.

 

find another crank pulley. that is trashed. might as well get a new timing cover while you're at it.

 

Good time to do a timing belt, tensioner and even water pump. 94

 

I would normally agree except for the fact that it's been under ~25k since it's been done. I'd rather avoid that misery until it's time.

 

Agreed.94
