Swap: D16A6 going in, D15coming out.
Problem:
After pulling out the D15 i buzzed off the crank pulley and bolt, so I could use them on the A6. How ever, it won't fit. The bolt is to big. I tried a bolt off of a D16y8,another D15, and just tried another off of a A6.

What gives here? We took the A6 apart to rebuild it,and It had never been taken apart. I know the origanl owner never removed the oil pan.
Any one ever have this problem?


Alright, so I now have the rite bolt for the crank pulley. But Honda keeps sending me the wrong pulley with the bolt. I was told ther where 2 options for that motor and the 1st didn;t work. Today I received the 2nd one and guess what. Again not the 1 I need. Here are a couple pics of whats going on.

The Bolt on the Left is the one I needed,



2 Pulleys that are diffrent but don't work....




Old D15 is 24mm



the D16A6 is 22mm

Has anyone else had this problem. Tomarrow I'm going back to tell them the "new Pulley" didn't work either.
By anychance , does someone have this smaller pulley?

Early 88 CRX Si motors (D16A6) had a smaller 22mm snout on the crank, and used a smaller diameter crank bolt. These were the ones that were 105hp instead of 108.
