Big Bertha

I was tasked with performing the 1000hr service on Big Bertha. She's the oldest piece of gear that Birch Equipment owns. She hadn't actually hadn't ran 1000 hours yet but the last person to do it didn't do it properly and water got into the hydraulic tank.

There's no easy drain plug to get to on this tank so I ended up just using a pump to get it out and then cleaning the inside of the tank by hand. It was fairly messy work. The problem from last time was that the previous mechanic didn't glean the gasket area on the tank or the oil filter housing or the lid. Just slapped it together. Eco-Terra is not cheap and that is a fairly large tank.

When it came time to reassemble I made sure that every mating surface was clean down to the machine marks and that black silicone was used as a sealant. You have to treat it as an engine oil pan gasket because essentially that's what it is.
