Cranksshaft size different ??? have a look

[osix]

This is not my photo but a close example .

i got a new crankshaft from the junkyard . in perfect condition .
the only problem i notice is that

"a " and " b " the size on the replcment Crankshaft i just got is Much larger by almost 1-2mm larger .

is it normal ? or better ? or did i get the wrong model ?

Assuming mine is D15b Engine

if it is not the same, it is from the wrong model

you are right . seem like D15b alone have about 3-4 model .
and i did manage to find another one that is the same .

what i notice is Mine on the Piston Arm " 3 "

and the larger one on the piston arm it say " 6 "
