Ugh. Spent about 45 minutes scraping and digging sludge out of the back compartment. There have obviously been a few leaks in this thing's past. Probably pulled a good 30-40 pounds of nasty out of it and that might 60-70% of it.
I've got one hose that's leaking pretty bad and is currently the biggest contributor to the above. Of course I need to disconnect two other hoses to get to the bad one.
I'm waiting for my BSP plug and cap kit to come in so I can at least limit the amount of additional fluid add back there. Should be here on Tuesday and then I'll pull that hose and get one made at the hydraulic shop in town. This should be the last of any major leaks. There's one cylinder on the boom that's weeping more than I would like....I'm just going to get it all cleaned off and keep an eye on it to see how bad it really is.
I'm pretty sure this little side compartment has no drain. There was a good 8" of oil impregnated slop in there that I just had to scoop out by hand.
It's right below all the hoses above, so when any of them leak, it all ends up down there to mix with the other dirt and shit. Great design.
