50 Hour Service

[Texas Dodge]

Going to do my 50 hour service tomorrow on the tractor. What do you guys recommend for draining the motor oil, hydraulic fluid, and front axle oil into? I should have right at 10 gallons all together.

Is your L3400 gear or hydro?

standard UDT for the transmission, 80W or gear oil for the axle. 30W for the engine.

Do you really need to drain the gear and hydro oil?
My Grand L3940 50 hour service said to just change the engine oil and filter, and then the 2 hydro filters (HST). I do not have to change the hydro/hydraulic fluid until about 250 hours.
Could be just different service schedules for different model tractors.

I use five gallon buckets for draining just about everything. I try not to go over half full since it's more effort to move them, and I have several buckets lined up for this. To get rid of the oil, I use it on my burn pile. One thing that I'm considering is to soak a post in oil and use it for a rub for wild hogs. A few guys, all teenagers, who hunt allot have said it works really good at bringing them in. I know that every one of my power poles are used by the hogs to rub on, from the one right on the highway, to the one next to the house. It's a magnet for them that used engine oil is supposed to duplicate. If not, it will be good for starting a fire with. LOL

At 50 hours, I drained and replaced everything. I just did it again at 300 hours. Then I do it at the beginning of spring when mowing season starts regardless of the hours. I've had mine five years, so 300 hours in that time works out to pretty good maintenance once a year.

I've only drained my hydraulic fluid the two times and won't do it again for another five years.

The 50 hour service is probably the most important service of them all.
You need to drain everything.

A new engine will naturally shed off some small and microscopic metal shavings into the fluids. Draining it all is the only way to purge your system.

If you wait until 250 hours..that's 200 more hours with metal shavings in your system.

No one wants that...except your service dept. Time to find a new service guy...someone a bit more honest maybe?

Follow the recommendations in your OWNERS MANUAL........... front axle fluid change is listed @ 300 hours. Anything less than that is overkill in my opinion.

The L3400 manual lists draining all fluids at the 50 hr interval.

My book says ALL fluids and so does my dealer and so do many many people on these forums.

Hey..you can do as you like but I ain't gonna be able to afford another $20,000 tractor any time soon so I'm taking good care of this one!
