Unlikely source for Connie parts - CAT Thermostat O-Ring
« on: June 23, 2019, 06:35:23 am »
First let me start ground level reality. I live near Egypt and not the one with the cool old pyramids. I don't know where my closest Kawi dealer is, let's just say it is more than 100 miles. Mail order is usually the way to go for me. Thank you to Murphs', eBay, Partzilla et al! However, we all know that small, inexpensive parts become big bills when you add shipping.

With the guidance from these pages, I elected to go with an aftermarket 180F t-stat and picked up a NAPA P/N 142 from the local NAPA man. However, he had no solution when it came to the big O-ring under the housing.

Over the course of an evenings' surfing and the help of a Stanley tape measure I re-acquainted myself with the standards of o-ring sizes and discovered the one we need is an AS568 dash size 138. Caterpillar list several in that size and my local dealer had one in stock! CAT P/N 127-8586. It is made of NBR and comes in a lovely shade of black for the low, low price of $1.61

BTW, I sent a note to the keeper of the list, but needed to toot my own horn at my personal victory!

Had to chuckle at the source of the o-ring….   Peterson Cat.

They built up a couple of 3412 generator sets for us that were used to power the portal cranes at the Portsmouth (VA) Marine terminal back in the early 80’s. We designed and built the paralleling gear that accompanied the gensets up to about the 60 foot level in the crane. The gensets powered a large motor-generator set that was even higher up, and it provided the DC that ran all the crane machinery.

Interesting stuff until you got called out in the middle of a winter night to trouble shoot a problem with snow, rain, sleet, and howling winds coming off of the Elizabeth River trying to blow your arse over the side of the elevated platform.

this is just based on the proposed size the o/p noted, and I cannot say for sure it is the "correct size", because I actually never measured one.. but they are cheap....

Had to chuckle at that too, as I had committed that part no. to memory. Can thank former member, and Cat employee, Mr. Bellm (sp?) for coming up with that little gem.

First met him at a TN Rally, and out of the blue, up in Nova Scotia waiting to get on a ferry.

Need to look in old Directories for the correct spelling of his name.

EDIT: I was correct with the spelling of the last name, and actually remembered his first name (Ray) before finding him in a '94 Directory.

Super nice fella, and trust he's still on top of the grass - AND - out riding.
