is the crankshaft diameter at the end were the crank pulley goes the same for the m113 and the m112?
basically can i run a m113k crank pulley on my m112k engine? seems you have simialr sizes as we run but cost is much less! something in the way of a 178 or 180 crank pulley to run stacked with my 65mm s/c pulley

 

I can measure the pulley hole and the key way and report back. But what about the offset and spacing off the rings. I have a damaged asp pulley that you can look at.

 

i have a damaged oem pulley if you want me to send it to you for comparison

 

C32's only use one belt while E55's use two belts so it's not going to work.

 

i wondered about that but the new rtr pulley and some others i surfed only had 1 belt setup. pte informed me it was more a 6 rib vs a 8 rib issue more than anything else

 

1 belt setup for the m113 kompressor engine? Maybe I'm misunderstanding but they ALL have two belts.

 

you are correct. i was looking at pulley pics and not seeing the smaller rib setup under the larger ring. of course if i can get it to line up its not mandatory to run two belts.

 

It won't line up though, the difference is HUGE.
