Makes sense to me.  I haven't tried to measure, but the main spring for the
small accumulator looks to have a lot more travel than the large accumulator
one does.  The spring has to exert a lot more force with the large
accumulator, and is wound with correspondingly heavier wire, leaving less
room between the coils.  And I think .130" of shim is OK even for the large
accumulator.

But for sure I am going to double-check, next time I start installing shims.
