In preparation for spring, I have been working on my Bobcat 853 doing some cleaning in preparation for replacing
the spool valve seals that run the lift arms and bucket. Removing the right side cover revealed a lot of hydraulic oil
in the bay below the right drive pump. Above the pump is the spool valve assembly which needs to be accessed
from the top by raising the cab. I could see that it was not going to be a fun job at all so watched some You-Tube
videos for some insight. There is a special tool needed when the spools are reinstalled to hold a spring under tension
and two ball bearings. I was able to see Bobcat's tool and decided it would be best to make something since I will likely
be working alone and always being short handed in an unsavory spot I might add. I added a spring to the assembly so
it will hold everything together in the reassembly. Also, I used a 1/4 inch ball end mill to make two little spots to hold the ball bearings with a little dob of grease.
This was made with a scrap of pipe and some 1/4 inch diameter rod I had laying around using an acetylene torch for fabricating.
It's a snow day here so a perfect to day to spend a little time in the shop and out of the weather.
