Hey what's up. Didn't know where to post this thread exactly but here goes. I've got an ITR engine in my civic ej. I'm trying to figure out the part number on my alternator belt. The belt currently has a part number of 31110-p73-505. The thing is that I can't find it online anywhere. There are other part numbers for it but I am not sure if they are the right ones. I went to autozone but they suck ***. They gave me a belt that fit too big. Now I don't know which one to get...

 

 

The number you listed should be the OEM number, which some part exchange systems don't do well with. lol

The 4PK760 (I believe that is what it says in your picture) that is going to be the number to use to find a belt the easiest, other than taking it off and measuring it. I did a quick search and it comes up as a 98-01 integera type-r, I checked rockauto and they have a few listed that should work, including a Bando belt that is the exact same part number, but if you are trying to stay local you can take that number in and see if they can cross reference that.

 

 

Seems like this would work?

31110-P73-508

 

Clearly says 4PK760. Just go to any autostore and order that.

For reference, if getting aftermarket drive belts you can use any of the below as well:

4PK925 for power steering

4PK725 for alternator

4PK815 for AC compressor

There's a lot of wrong belt numbers out there and Honda's manual here in Australia was actually wrong. They list 4PK925 for the AC as well and when I went to fit it, it was way too long. They also had the wrong length listed for alternator and listed 4PK820 which is also too long. 4PK760 is short enough to be tensioned and since it's already on the car, you know it will work.
