Okay, I’m beyond frustrated now, after 3 different belt sizes non of them seem to fit.

gates part numbers.
K060539
K060532
K060535

i have a 16% m7 sc pulley and stock crank pulley.

can someone tell if one of these should fit or do I need a different one.

 

I also double checked the sc pulley crank pulley and idler pulley. All with in sizes.

 

I’m going to buy a stock size belt daco and see if it fits.

 

Might help a tiny bit, but I run the 60532 on my 17% pulley and OEM crank and 0% alta. It's tough to get it on until it stretches with use. Then it installs without issue. No belt slip afaik.

I've heard 60535 is also an acceptable alternative to the 17% but could result in slip, so I avoided it. I would think it would be ideal for your setup....

 

Well an oem belt worked! Wtf. One of those pulleys is not right. It barley went on and it shows almost the second hole on the belt tensioner tab, one whole one is showing plus the space in between them.

The stock belt is almost .75 of an inch longer than what is called out for this set up.

soo not the car turns over but no fuel coming from pump 🤣 lol

 

The K060539 is the JCW (11% SC pulley); would think that would fit better than the stock S K060535.

Would suspect the idler; frequent enough failure item, maybe a previous owner swapped in something else (muh BMW spares stash) 'in a pinch' or maybe a replacement alternator or AC compressor had the wrong pulley swapped in from a rebuilder.

Maybe your car is trying to tell you something about the impending future of that

 

I have a new fluid crank pulley, and new idler pulley from ecs tuning.

The fuel pump issue was due to not having enough gas in the tank and the front end being lifted up, also I believe the timing is off slightly because it started and died but a rough start.

I did not measure the alternator or ac pulleys, so it must be one of those. At least I have a belt for my jcw 03 hahaha.

Going to dig into the timing issue this weekend, and try again.

 

USe this. excel skills required. Use drop down menus to select sizes

It should be made a sticky for all. But I am going to close the drive access as its my private/teacher drive. But would be nice if @IB Trafficking Posted the file here again as a sticky.
