The question is not about the crank journal diameters whitch seem to varry between years, but just about putting the type-s pistons.

I did a search, but some people say it is necessary to rebush to acceplt floating piston pin, some others say it is not necessary....

So my question is what is the exact difference between these rods ?

Is the diameter different ??

Is there a lubrification hole on both types of rods ??

... ??

 

Really none knows

All A1 rods would need to be rebushed for floating. Diameters on both ends are the same.

 

Yes, but could you explain me what it exactly means "rebushing" in this case???

If I understand well, the diameter is the same for floating and non-floating pin.

So what is the difference between bushings ???

I would greatly appreciate a precise answer.

bore out and put in another bushing that will allow the pin to float

 

So what is the difference between the bushing you bore out and the one you press in if the both diameters are identical ?

One is for press fit (no movement), the other is for floating (floats). Likely a oil lubrication hole and a slightly thinner bearing thickness on the floating...just a guess I haven't done it personally I paid a machine shop to do it.

 

Now I see it much more clearly

- the non floating bushing is pressed by force into rod and does not have possibility to move (turn) into the rod, it is only the piston pin that moves around the pin,

- the pin into a floating one has possibility to turn into rod and into piston.
