So I got just over 100 hours on my 5085M, so it was time to do the 1st oil change, replace the hydraulic filter, tighten all hose clamps and grease all the fittings.

So here are the needed "ingredients":

That hydraulic filter is a monster! Just look at that 5 gallon bucket next to it. I started with the hydraulic filter since it was cold this morning and I was worried that I'd loose a bunch of fluid when swapping out the filter, so the thicker the oil the better. I followed the manual and hooked a shop vac up to the fill port:

It worked amazingly well. All oil that was thinking about coming out after removing the filter was immediately sucked back in. After getting that done, I pulled the old inner filter to examine it. Looked good from the outside with no metal shavings or anything like that:

The inside of the inner filter had what looked the some pieces of an o-ring:

I'm not sure what to make of that, but it looks like all of it got trapped, so hopefully it is nothing to worry about.

I poured some of the old oil into a clear lid and compared it to the brand new oil. It is definitely darker, but nothing like the engine oil!

From above:

From the side:

It's probably because it got mixed up with the hydraulic oil from my 3 way blade that was used on the New Holland loaner that had some really nasty looking oil. But I don't think its too bad.

The engine oil change went without a hitch. No hose clamps were loose and everything got a good greasing.
