L3800 50 hour service

[cougar21300]

Red Sox,
Also remember at some point to check the tension on your fan belt to make sure it's still snug. It will stretch in a bit from new, especially once the weather warms up

A good tip to add to my checklist.

Where is that oil fill point on the valve cover for a L3800? I looked today but didn't see it.

Thanks.

Its on the side, just up from the dipstick. Hey there are a lot of good thread on here about methods to change the hydraulic and hydro filters without loosing too much fluid.. I used the vacuum cleaner method but it put fluid spray into the vacuum. Another method is the park on a steep hill sideways with intended filter up hill. I havent tried this. Other method is just be darn quick.. Good luck and get back to us if you need anything..

Hey Rail Dawg, did you do your 50 yet and if so how'd it go?

On my 07 L2800 it is right behind the radiator hose outlet on the front right side of the valve cover. It is recessed a little.

I wish mine was there, it's a PIA having it on the side of the engine where it's harder to get at with a full jug of oil.

Mine also has the side fill along with the valve cover fill. I did not find the valve cover fill until just before the 300 hour service so I know what it is like to add oil especially with the loader attached. I was a nice surprise when I found the valve cover fill. I have not looked at the other L-series to see if they have the valve cover fill.

I did my 50 yesterday and holy cow what a mess I made! It's all done and cleaned up now but next time I'm going to have a better way to catch oil.

What surprised me is the roughly 1-2 quarts of hydraulic fluid you lose when changing the hydraulic oil filter. No wonder guys use a shop vac..... Even when I went as fast as I could the fluid gushes out pretty quick. Be ready!

The other lesson was removing the engine oil dipstick when draining oil. It took me 5 minutes of oil barely draining out before I pulled that stick out. It flowed great after that.

Next time I'm going to have a big flat plastic catch basin and lots of old rags. That and my shop vac and it should go a lot better.

This thread did help a lot.

Take care!

Next time you will be draining all of the fluid so it really won't be that messy. Probably should have done it this time despite what the manual says. My opinion - stated many times.

A washtub from Tractor Supply or a feed store works great for catching large amounts of fluid.

You can also remove the oil filler cap for a better drain. You have to remove it anyway for the fill-up.

Sorry I should have mentioned that!

Has anyone tried the steep side hill method of to retain the fluid when changing the hydro filter? I used the vacuum thing last time. and it worked well, but coated the inside of the vacuum with a fine mist of fluid.

If you restrict the shop vac opening it will help. I use a step down adapter on the shop vac. The opening at the end is only 3/4 of an inch. This keeps the flow down so you do not get all the fluid mist. All you really need is a little bit of vacuum. Since changing a filter does not take long, it will not hurt the shop vac.

I have a 3800DST. Does anyone know what hydro fluid is installed originally? Super or regular. Is super mainly for HST models or both? When i change my filter i don't want to mix two different types of hydro fluid. At least the manual says not to mix. Thanks!

As far as I know, and have read.. all 3800's whether gear or hydro come filled with SUDT from the factory.

I wonder if one could run the tractor up on car ramps on one side so it tilts to the side to change the filter and not lose too much fluid?

My L3800 won't be here for a couple of weeks, but I might give it a try for the 50 hour service.

 

[PuckNPirate]

I got the skinny from the dealer and sent an email to to Kubota Corp. to clear the air on whether changing the hydro oil is required at 50 hrs. I also asked Kubota Corp if it had to be done by a dealer. Their response...." To keep the warranty on the unit you need to do the requirements that is shown on pages 46 & 47 in your Operator's manual. Doing the work yourself or paying someone to do it, doesn't void the warranty. You do not have to change the hydraulic/transmission fluid until the 400 hour mark."

I did run one side of the tractor up on some 6x6 wood blocks to remove the hydro filter and replace with new. Wheeeww! THat was fun. I only had to top it off with 1-1/2 quarts. Make sure you move your FEL lever around and around to relieve a lot of the pressure.
