Changing my 425’s Hydraulic fluid.

[CreativeGuy]

Greetings, I’ve just reached 200 hours on “Artie” my PT 425. While I have changed the hydraulic fluid filter every 50 hours, I’ve not changed the fluid itself. It still looks pretty clear. Can I go with just another filter change, or should I really be changing out the fluid as well?

That's gonna be up to the other folks and you.

Personally, I've never changed the hydraulic fluid in my 2001 PT425. I've added a quart every 50 hours to makeup for filter change. I've got 1000 hours on it, so I've added 5 gallons of oil to it over the years, plus a few more for hose leaks/replacements. I've always added Mobil1.

We'll see how it goes.

Change it. You'll sleep better. Lol.

If it's clear the mossroad method should be fine. If it's low, milky at all find/fix where the leak or water is coming from and change (or process) the fluid.

The mods recommended like adding a tank magnet etc are good advice

Thanks,
I’ll continue change the filter and add as needed.
Cheers,

After seven or eight years, I find the oil in my PT gets darker, thins, and affects the hillclimb ability. If the bottom of the tank is still shiny with a bright flashlight, I would not sweat it. If your oil is still clear, and the viscosity looks good, I would go for the patented @MossRoad method.

All the best,

Peter

I have had my machine for 15 years and have yet to change the oil. That said just wait. You will rupture a hose and it will get changed automatically for you.

Ain't that the truth!
