This gives:
SA=LA1+LA2+0.30-LA.
To calculate the each single shim thickness note that:
SA=SA1+SA2
where "SA1" and "SA2" represent the shims for the right-hand crankcase half 1 and the left-hand crankcase half 2.
Considering the alignment of the shaft, this gives:
B
SA1=LA1+0.15-LA/2;
And finally, the second shim thickness: SA2=SA-SA1.
