[C38] Binding Halyards/Masthead

Sat Jul 5 20:06:00 EDT 2008

Hi Russ,

"Nothing difficult is ever easy"

The covers just cover the ends of the sheave pins keeping them from falling
out.  I found some old pictures I took and there are two covers, one for
each sheave pin.  Be prepared to have some choice words for the retainer
screws as they will probably be corroded to the mast.  I sprayed with PB
Blaster before I attempted to remove them.  Later, I replaced the screws
with Allen head stainless screws making removal later easier.  I also
coated the new screws with waterproof grease.

You can see inside the crane by looking in from the ends but that's about
it.

If you rig another climbing rope at the crane so you can climb without
using a halyard, you will be able to remove the divider plates from the
crane as well as both sheaves but just remember to solidly secure the
sheaves with small line or wire otherwise you will lose them down the mast
when you remove the sheave pins.  Without removing the halyards first, it's
almost impossible to remove either sheave without dropping it down the mast.

As you can see from the photos, my divider plate was worn from corrosion
and lack of lubrication between the sheaves and divider.  That is why it is
good to also remove the divider plate because you will want to dress it
with a wire brush and grease it before you reassemble everything.

Hope this helps.
