:: How shall I install the Mazzucchelli crank?
-
I have an semiround Mazzucchelli crank I will install in my engine but a closer look made me wonder one thing.
Have a look at these pictures.
It looks like the shim inside the bearing is already on the crank from the manufacturing.


The withs of about 33 millimeters are similar to the stock crank withs so I believe that I must install the bearings with no added shim inside.
The following instructions doesn´t tell this at all but I believe I am right.
you could try to pinpoint the measurements from the ´ring´ to ring and try that on a stock
if its the exact same do not add rings
different prehaps you have the ability to remove the rings and add normal shims.

I have the exact same crank on my setup, install it whitout the shim rings.
