Hey guys, I need to change the drive belts on my FD. Im still running the airpump.
The airpump belt especially is looking a bit worse for wear and the edges are fraying..

So to the point. I understand the stock belt sizes are 6PK1045 and 5PK1355.

Thing is, one of the belts I have here is 5PK1350...will this be OK? I figured it would be ok as its only 5mm shorter - but thought id ask before i go and tear them off and find this one wont fit..

cheers

 

Hard to say, try it and see if it fits. Most times the parts store seems to have the wrong belt sizes in their computer, I usually end up making 2-3 parts store runs for belts. Once you find the right size, make note of it and have it written down for next time.

It gets way harder when you go with underdrive pullies, airpump idlers, etc.

Just confirming belt sizes 5PK1350 and 6PK1045 worked fine on my stock pully setup.
cheers
