Dean - you may
be right - here's what I've found after disassembly and
degreasing:
Monty's drawing
(wheelhorse?) - calls for a 1/4" x 15/16" roll pin on printed parts
list
Two arms in my
collection have a 1/8" x 1" roll pin - I've removed them to check
dimensions
another has a
1/16" hole (no pin) - could be a broken pin as you suggest
I will examine
them all very closely for broken pins, but I also think that its entirely
possible GE went to bugger pins as time went on due to breakage.
Industrial archeology, ain't it great?
Hi,
It isn't impossible, but seems
unlikely. I'm taking for granted that the arms that you saw with the
small hole was disassembled. The small hole may be because the roll
pin may still be in the bar with the ends sheared off. When one of the arms
came apart on my deck some 17 or so years ago, I could not easily see what
held it together with the grease and dirt on the shaft. Only after
close examination did I discover that the ends sheared from the pin and I
had to drive it out for a new one.

information
Monty McGraw was kind enough to post a picture
and parts list to answer my question about how to assemble a front mounted
mower arm. It's clear from the diagram and parts list that there is
indeed a 1/4" x 15/16" roll pin pressed through the shaft to retain it in
the outer cylinder. Today I met with another list member to find
some parts, and in examining a few arms in his collection and mine, we
find the hole through the shaft (in the position indicated in the diagram)
was no where near 1/4". In fact it appeared to be about big enough
for a slim cotter pin. So apparently there was an "early version"
which had a much smaller pin, and a later version which had the 1/4" pin.
I am sure I'll be able to figure out how to deal with my arms (drill
the hole larger!), but just thought I'd share this bit of trivia with the
group.
