Title: Re: (ET) mower arms information
Dean - you may be
right - here's what I've found after disassembly and
(wheelhorse?) - calls for a 1/4" x 15/16" roll pin on printed parts
Two arms in my
collection have a 1/8" x 1" roll pin - I've removed them to check
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?
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.

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
