Hydraulic cylinder repair by Matt at Diesel Creek

Matt showed how to repair the hydraulic cyclinders of D4 Komatsu bulldozer. He had deferred such repair for 5 years, although it cost him much in terms of lost hydraulic fluid that leaked.

As usual, it is demonstrated that disassembly was mostly hard and challenging.  He improvised:

     1.  How to remove the cylinder cover by welding a flatbar which he hammered;

     2.  Pulling out the internal rod by using a back hoe.

The seals and glands were bought from the store and Matt reinstalled them well.
