Hydraulic Oil Changing Questions

[placervillebob]

2005 L2800 HST with 175 hours
I bought this tractor used several months ago and because of lack of service history will be changing the hydraulic oil soon – using SuperUDT2. I have a few questions:
- My drain containers will not hold 6+ gallons – is it possible to use a drill operated transfer pump to suck out some of the oil (from the fill port) before draining the remainder from the drain plugs?
- Or would you recommend initial drain via one of the filters first then using the drain plugs? If so which filter? Of course I plan to replace both during this service.
- I have a loader as well as backhoe attached – is there a position of the pistons that gets most of the hydraulic oil out of them for a more complete oil change? I think there is oil on both sides of the piston – so piston position may not make any difference.
- I have been told there is no screen to clean on this model – does anyone know if this is true? If there is one – where is it located?
I am having a bit of the HST noise as well as a little jerky movement of the loader and box scraper (when it is attached) – hopefully the oil & filter changes will help.

Thanks for your comments

You can pull the plug and drain part of it, replace plug and change containers then pull the plug again, it comes out fairly slow after the inital drop.
No the loader and back hoe position doesn't matter as like you said they have nearly the same amont on either side (slightly less volume is in them when retracted).
Most if not all the newer models have done away with the screens, filters do all the cleaning work.

By switching over to SUDT2 I believe you will notice a difference in the noise and the function of the machine.

Perfect - Those are just the answers I needed.
I was afraid, once I removed one of the drain plugs, I would have 6+ gallons of oil to deal with and couldn't get the plug back in to change (or empty) my drain pan.
I have heard that switching to SUDT2 would quiet it a little - mainly from other threads on OTT.
Thanks for the answers.

When a hydraulic cylinder is retracted there is less fluid in them. Definitely have all of the hydraulic cylinders fully retracted, same when you check the fluid level.

Consider getting one of these to catch all your oil:

Concrete Mixing Pan

Worked great for my L3800 oil change.
