John,
I concur with Phil Agur's theory.
It appears on your photo that the Separator Plate is missing.
While it does vary with some folks, I believe it's not prudent to have that
plate MISSING.
It's a thin sheet of aluminum (1/8th inch?) setting between the sets of
Sheaves.
On my crane, There are Two sheaves forward and Two sheave aft with the
Aluminum sheet between each of the forward/Aft sets.
There is a bare 1/16th inch clearance between the sheaves and the sheet. I
imagine if the sheaves are Ball Bearing type the clearance could be less.
Standing a half inch or so Above the Sheave, the plate protects from a "Jump
Off" the Sheaves of the line..
Sorry no picture, but I could do a diagram if you wish..
Best,
Ralph Ahseln

Subject: catalina27-talk: Stuck Main Halyard
Take a look at a picture of my main halyard which has fallen off of the
sheave.
http://www.sailtravis.us/etc/stuckHalyard.html
According to the Owners Manual drawing 4.1.6, the dimensions for three
sheaves are identical, two jib halyards forward, and one main halyard
aft. Yet the opening for the single main halyard sheave is the same as
the two jib halyard sheaves. I don't see anything to keep the halyard
from binding up as it did.
From my picture, is don't see anything broken or missing. Is this a
normal problem?
John
