M7040 Hydraulic Filter Change

[Treesanddust]

Getting ready to do the required 300 hour hydraulic filter change on a M7040.
I'm looking for information as to how much hydraulic oil I'm going to lose when I pull the old filters off.
Will I be draining most of the hydraulic oil or just a gal or two?

Thanks!

When my son changed them on our M8540, he lost about five gallons, it sure shoots out of there. Our dealer said their techs could do it and only lose a small amount, but I guess they are a lot better at it. We only lose about a quart when changing filters on our L5030.

Maybe someone else has had better luck.

For the umteenth time - just change the hydraulic oil, too.

Unless you are broke or put 600 hrs. a year on the tractor it is not that expensive. It will get rid of the winter condensation as well.

I would have to pull my Operators Manual out to check, but we pretty much go by the schedule in there and only change fluid when required as our tractors don't sit during the winter. I have spoken with the Service Manager at our dealer and that's what he advises.

If changing fluid more often makes someone feel better than that is what they should do.

Appreciate all the replies.
We go by the maintenace schedule in the manual for most things, more often for some items, so I'm not totally opposed to replacing all of the hydraulic fluid every 300 hrs.
Our Kubota dealer doesn't carry SUDT which is what we're running in it, so I have to order online and have shipped in.

Think I'll just replace the 5-6 gallons this time.

These 300 hours seemed to happen pretty quickly for some reason.

I am guessing the M7040 is pretty close to the 8540 and ours takes fifteen gallons of fluid for the transmission, so to me it makes no real sense to change the fluid twice as often as manual recommendations regardless of what anyone says. I have been operating farm equipment for well over fifty years and know of no one who uses them for a living who does this. Many farmers use their utility tractors well under 600 hours a year and still stick with the schedule if not going a bit over.

I am not broke and one of the reasons I am not is because I don't spend money needlessly, well not for this anyway. No disrespect to anyone.

If you don't want to lose any oil, you can, according to the Operator's Manual, drain the fluid, change the filters and then put the fluid back in. We decided that was too much trouble, but may give it some consideration the next time.

Seems backward to me. Book says drain fluid and replace filters at 300 hours; drain and change fluid at 600 hours. I don't have a pan I trust is clean enough to put oil in then pour back in the transmission. Did anyone ever inquire if Kubota just got this reversed?

No one mentioned using a shop vac on the filler port to provide suction to minimize fluid loss when changing filters. The vac doesn't pick up any fluid. It's worked on smaller Kubotas anyway.

I would guess your M7040 will be the same as my M6040. Mine took a little over 60 US quarts - 15 gallons. I changed mine at 50 hours and will again at 600 hours. I will totally drain down at 300 hours - install two new hydraulic filters - and refill with the fluid I just drained.

BE SURE you have a single container that will hold ALL the fluid. Trying to swap out a full container as the hydraulic fluid is draining - not a pretty picture.

I intended on using plastic five gallon buckets. Then I realized how tough a full bucket was to move and replace. I have a large Tupper Ware tub that works just great.

If your Kubota dealer does not stock SUDT, you need a new dealer.

The first trans fluid change on my old L4630, I was using 5 gallon buckets and, despite being warned by my neighbor about this, I proceeded to splash/spill fluid all over myself and the ground.
With the M, I thought I would preempt the problem and used a 15+- gallon galvy tub...by the time the last drop had dripped, that tub was literally brimming and I had to skim the excess off till I could safely move it; and It was heavy

Yes, I checked with my dealer and he offered to send a tech down to do the initial service for $100. Fortunately my brother is a mechanic as I'm due for a valve adjustment.

It helps to have a screwed up sense of logic, as I do. My take on this - change the filters every 300 hours - change the fluid every 600 hours. Would be REAL HANDY if they had 600 hour filters.

I wish your brother was closer - I'd gladly pay him $100 to do my valve adjustment.

My M7040 operators manual shows hyd system holds 11 gallons.

 

[oosik]

Glad you spoke up Tx Jim. My Op Manual says - 59 quarts ( 14 gallons + 3 quarts ). At the 50 hour service it actually took 60 quarts plus a smidgen.

Tractordata shows 10.6 gallons for M7040. My M7040 is an '11 model.

I use a large rubbermaid style tub with lid I bought JUST for changing oil, lid stays on it when not in use to keep it clean. Fits perfect under tractor and catches all the oil.

I use a drill pump.cordless drill to pump the used oil out of the tub back into the tractor.

Same drill pump used to pump out of the 5 gallon buckets when I put new oil in.

 

[oosik]

Farmer - I'm going to have to get something like your drill pump. I just can't see me spooning 15+ gallons back into the tranny.

Tx Jim - Tractor Data shows 10.6 gallons for my 2009 M6040. THAT IS DEFINITELY WRONG. At least, for my M6040. Here is the scanned page from my Owners Manual. The hydraulic capacity is shown within the box - upper left corner. Actually, when I changed the hydraulic oil and the two filters - it was real close to 61 quarts. Actually, when I changed the two hydraulic filters it took right at 61 quarts.

I have this one:

https://www.amazon.ca/Milescraft-13...ocphy=9000041&hvtargid=pla-435281554309&psc=1

I just used regular short "drinking water" hose that had a bad male end, cut it in two and put a replacement female end on it. I can pump almost every drop of oil out of the bin and directly into the tractor , maybe a couple minutes? Don't even have to move the bin from under the tractor
