I have cut hydraulic filter apart
It had no metallic shavings but it did look as if there were brass flakes in it

Usually see brass from the slipper shoes of the pumps or motors. About the only places I can think of that you'd get brass from.

Brass is/was a metal (or to be more correct a metal alloy) the last time I looked.
There is probably contamination all the way through the hydraulic system because even the standard Cat filter is not a particularly fine micron element. Add that to the fact that if the filter plugged enough it would start to bypass and, hey ho, metal everywhere.
It would appear that you have a major strip-down and cleanout ahead before it would be even worth contemplating hooking up gauges and testing anything.

That may be related to the lack of drive on one side, or to the main hydraulic pump, or both.

Well let’s hope for the best

Either way be under no illusions about the cleaning challenge you face, otherwise any new parts you install could easily be torn up by residual contamination in the system.
Maybe this was the reason the former owner decided to offload it..?

Yes I’m prepared for this.
I was thinking the same as if why he had wanted to sell

Mobiltech / 92U 3406 - What brand of 0W-20 are you using in your cold weather applications?
I am looking to change the oil in my hydraulic system on my 2008 CAT 242B and would like to be good for -30 or -35 C.
I see that the CAT Hydro Advanced 10 is specified for a pour point of -39 C. The spec for the original CAT Hydro 10 was a pour point of -30 to -33 C. But as you said, the controls get sluggish with the 10W ... and perhaps pour point is not that great of an indicator for real life conditions.
Just looked up CAT TDTO Cold Weather 0W-20 ... is has a pour point of -54 C.

We used Caterpillar TDTO 0W-20.

You can use Cat TDTO, or any other 0W-20 multigrade TO-4 oil, to get the low ambient temperature coverage that you are looking for.
Any of the main oil company brands should work fine, I would just stay away from parts store brands.
