Title: Re: (ET) mower arms information

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.

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.
