I am in the process of upgrading my Beta M35b engine
from a 40 amp(?) factory alternator
to a 200 amp Balmer AT alternator
with a serpentine pulley system. The alternator and pulley kit came from Electromaax and was ordered specifically for my engine
. Not surprisingly based on all the other issues/problems I ran into with Electromaax, the pulleys, when installed, do not align perfectly with each other. The kit had a spacer for each pulley but they still do not line up.
I am wondering how much of an alignment error is acceptable assuming a belt span of about 9 inches between pulley contacts.
I realize that perfect alignment is ideal and will allow longest belt life but I am wondering if I can get away with a 1/8 misalignment without causing a big belt wear problem. How about 1/16" misalignment?
I do not have the exact misalignment figures yet as the pulleys have different thicknesses for the edge to first groove dimension and a simple straight edge test to the side of the pulley is not conclusive. I will have to do some detailed measuring taking edge thickness into account.
