I am currently building a 916 engine and have some questions about the crank shims.
I have done a couple calculations and one number has come up different on my measurement on one half of the cases.
Formula “S”= P1 + P2 - I + 0.15
Calc #1-
44.7 + 44.5 - 87.7 + 0.15 = 1.65
P1= 1.025
P2= 0.625
Calc #2-
44.7 + 44.3 - 87.7 + 0.15 = 1.45
P1= 0.925
P2= 0.525
I ended up putting in the following shims
P1= 1.00
P2= 0.5
How critical or precise do I need to be?
Any input would be appreciated.
Side note: I’m not a mechanic and this is a bucket list project I’m working on.
