Jack,
I recently replaced one of the bushings on my Alon. I found
it useful to grease the bushing thoroughly before
"persuading" it into place with a wood block and a mallet.
My washers were hard to install because the clearance was
tight - lining everything up at once was a challenge.
I ran into a question which was not previously answered in
this forum which you will also face: How does grease get
from the Zerk fitting to the inside of the bushing?
The bushing I received had no extra holes in it, meaning
that after assembly, grease has to somehow work its way
around the ends and find its way between the bushing and the
pin. Am I missing something? Should the Zerk be removed and
a hole drilled through the bakelite bushing (with the pin
removed of course) to allow grease to penetrate? The old
bushing did have an opening which looked like it was beaten
into place, rather than drilled. I'm sure some of you
lurkers must have replaced your bushings - what did you do?
