Need to change hydraulic oil in L3430

[TNhobbyfarmer]

Very difficult job? Anything specific to watch out for?

Easy, pesy. Just have catch pan big enough for the amount of fluid.

Lowes sells large plastic bins for mixing concrete and other stuff. Makes a cheap but large catch can for draining anything.

Just changed mine for the 300 hour service.
3 drain plugs and two filters...easy!
Depending on the access to your fill plug you might have to rig up a funnel with some tubing.

Got a big galvanized wash tub to drain the L3130 into, over 12 gallons, you have a couple of plugs in the center and one on each side for the reduction gear housings on the axles.

Instead of a funnel I just used a pail pump that fits in and screws onto the spout of the oil bucket.

Even though there are multiple drain plugs, only one fill plug?

Only one fill port on mine, behind seat, the transmission fluid for HST and standard trans might be different.

 

[David_Kb7uns]

On transmission only one fill point, on engine there is 2, one by injection pump and one on valve cover.

It's a relatively simple job which is made easier if you have a lift. Otherwise, a creeper on a smooth surface will do. If you're changing the front axle / hub fluid as well, it tends to drain down onto the rim and tire. I cut up a 2 liter soda bottle to divert the used oil into the drain pan.

Like everybody says - it is easy. Just make sure your container is big enough and drain all the drain plugs not just one.

I put a shower drain in an old galvanized pan and piped it to a 55 gal drum with flex couplings for draining. For refilling I set the 5 gal bucket high and use one of those rattle syphon hoses.

I made this for my dozer oil changes where I need to handle 25 gals but it works good for the tractor too.

That's almost clever, is that a shaker siphon hose putting in new oil? now what to do with all that used hydraulic oil?

Yes, new oil going in. The fill port is in a hard to reach place - even with a funnel. Just not having to hold up the bucket is a big help. A pump would work and be faster but this syphon works fine for me. I use 10 Wt . 30 wt, I don't know - would be OK if it was warm enough.

Used oil goes to the county recycle shed in the next town over.

After letting it settle out for awhile in the tub, I put the hydraulic oil back into the used 5 gallon buckets, and actually used it to help flush the system on the RTV when it got water in it. Then used the water contaminated oil for burn piles and the cleaner stuff I use in the winter to cut the chainsaw bar oil so it flows better.

Guess you found some multiple uses for used hyd. fluid, I also use it in chainsaw and put on outside wood to hold off rot.

I have one of those siphon hoses, for some reason never occurred to me to try it on hyd. fluid, thought it was fuel only, I'll try that next time I change my hyd. oil, been 200 hrs since I changed it, I used that same Shell hyd. oil, thought it was thicker viscosity then TSC oil, thinking it might slow my gears down faster, didn't notice any difference, I'll go back to TSC brand.

What you suppose the recycle shed, next town over does with the used oil?
