I was wondering if the 1.5 and 1.6 crank pulleys were interchangeable. Reason being is because I want to use the crank pulley tool I have but it won't work for the 1.5 crank pulley because it doesn't have that 50mm hex socket.

 

i was wondering this too. will my d15b7 pulley fit right on to my d16a6 block?

 

yes
