Cat hydraulic wrench
« on: September 13, 2018, 01:43:26 PM »
My job today was to make a wrench to disassemble Cat hydraulics.  Mainly  the big ones on the backhoe tail. 

  I started with a high tech autocad program and all my education in advanced engineering.

   I made cardboard templates.

From there brainstormed with the boss on his needs and uses.  Found the gas axe and a grinder plus some heavy steel plate.  3/4" mild for the handle and high temper wear plate for the hook.

   Burned all the hair off one hand and deafened myself completely for three hours and then spraybombed this black.

The bossman is jazzed he now has a 500 dollar tool for three hours of peon wages .  He came out way ahead.

   It is 32" long and will take a 6.5" Cat cylinder cap firmly.  Weight is atrocious and the two regular workers who will have to use it will hate me forever.

Its a solution to an old problem.  He cannot find this wrench in a factory made version.  If it were made it would cost two firstborn children. 

   Monkeys like me are far cheaper and he designs it for the most part.  I won't be here when it sees first use but I made it look good and solid as I could to make sure the do not curse me forever.  They are my friends after all.

Nice work on that Brian. I'm sure the heavy weight on that will be a plus.

He painted the working end Cat yellow and declared it reserved for newer undamaged units.  I think he likes it a lot.

Or a fierce wasp.

Great gob on that tool, the extra beef and weight would no doubt be beneficial if the body is mild steel.

The Red Cola bottles are closed up pretty tight.  This will make it easier.

   Worst part, no damn hang tag!  How are we supposed to know the COO?   DAMMIT....

Last week it got the first use.  I was not there.  A happy un injured ex boss reported two burly men and a 10' cheater pipe only managed to loosen the gland nut.    No damages to men or machine.

   We shall call that success.  The temper of the steel in the old wear plate was right for making a good hook.  Very critical part.

If it's heavy it's good!
