Oil & Fuel 50 hour service

[foggy1111]

Double check on 50 hour service. Does anyone change the hydraulic oil or just that filter as shown? Thanks.

The other filter is engine....and engine oil.

I did hydraulic oil and filter.

Some owners do a full hydraulic fluid and filter change at 50h. The manual specifies changing the HST (transmission) filter at 50h and every 200h thereafter. Hydraulic filter and hydraulic oil are both changed at 400h.

YEah....No offense......but you dont have a 3560.....and your model may have different requirements. Just saying.

Is that in reference to RJ? You might want to get a clue & notice that his L4060 & a L3560 share the same owners manual & maintnance intervals, as do all of the Grand Ls. Just saying.

What does your owners manual say? Yep, Change engine oil and engine oil filter at 50 and one or 2 Hyd filters at 50 and no mention of changing hyd fluid until 200 or 400 hours like my L39xx. You can do what individuals you don't know say because of whatever their reasoning or do what the factory that engineered and made the machine says. Or whatever you want to do and when you want to for whatever reasoning.
Personally I change mine per owners manual for the specific machine. The owners manuals have changed over the years on the same or similar machines so someone may tell you they do what the manual says and they are telling the truth for their 2009 machine but the manual for a 2017 machine may be different. Tolerances and products change and that's life with machines and manufacturing. Some people say one company is following other companies ads of extended maintenance because of sales competition but that is foolish in my opinion with these machines.

Same as JOHNTHOMAS; dealer says the same thing.

I only changed half the hydraulic fluid. The other half I took a bath in after I discovered that the vacuum trick and you dont lose much oil swapping the filter is an urban legend.

It works as long as you get a good seal where the vaccum goes into the fill port. If you don't get a good seal (or it falls out), you get a hydraulic fluid bath...

I changed the oil also. If I'm going to spend thousands on the tractor I don't cheap out on a $100 pail of oil.

Nope....that was in response to Grouse09 whom shows a B2650 as his tractor. Just saying. Grin.

I'm sorry I asked.....as I should have asked model specific to my Grand L 3560 HSC. And I did wonder about how much hydraulic oil would be lost when the HS filter is replaced.

In my owners manual for the L3301 the 50 hrs service says to:
1) Check Engine start system
2) Check wheel bolt torque
3) Greasing
4) Adjust clutch
5) Replace transmission oil filter (HST)
6) Replace Engine oil
7) Replace Engine oil filter

My only problem is how much transmission oil will I lose trying to just change the transmission oil filter?

When I changed my B2650 filter there wasn't that much lost, just have to be ready with the new replacement filter on hand and gasket lubed with fresh oil. Lost less than 2 litres.

 

[Fallon]

I lost a few drops at best on my L3200 & L4060 using the shop vac trick. Filters were off for quite a while too.

Even if the manufacturer says to NOT change the hydraulic fluid PLEASE DO CHANGE THE FLUID.
I waited till the recommended 200 hour and I was amazed at the debris that came out of my system that was rolling
around inside my tractor from new.
There were metal shavings from the machining of parts in the fluid that I should have taken out at 50 hours.

The other thing to consider is contamination from other implements. Do you rent or use implements from a dealer/ rental place/ friends/ neighbors? If so, do they use the same fluid in their hydraulic implements as you do? When I get a new implement I change the hydraulic oil after 50 hrs as well.

Any debris you can see and finer particles you can't see won't make it through the filters before it's pumped through the machine. Change the filters regularly as per the tractor's manual so they never get plugged with filtrates, and the oil should be perfectly fine to 400 hours (as per my B2650 manual). Changing the oil at 50 and or 200 hours is a waste of money and good oil, unless there's obvious symptoms of degradation like color darkening.

Changed the filters and fluid on the Grand L3130GST at 50 hours and let the fluid settle in a tub and was surprised how much metal settled out. The Grand Ls usually take 2-3 5 gallon buckets of Super UDT so not cheap but worth it on the GST for improved shifting.

Letting it settle also points to why Kubota isnt that concerned. It does the same thing in the sump. Most stuff just settles out to the bottom of the sump & stays there until you drain it. What doesnt settle out gets caught by the filters.

Keep the filters changed as recommended. Cavitation from a plugged filter or strainer can destroy a pump faster than contaminated oil in most cases.

I was at the my Kubota dealership (I think the largest Kubota shop in my Province) getting filters for my B2650 200 hour service, and asked the service department head about this very issue of some owners on these forums insisting on changing out all the hydraulic oil with the filters at 50 or 200 hours mark instead of at 400 hours as per manual. He said they DO NOT automatically replace all the hyd oil when they service these tractors at 50, 200, or even 400 hours, and that 800 to 1000 hours is not a problem for premium udt oil to last perfectly fine. Unless there bad fluid discoloration, bad noise, or persistent metal shavings/bits showing up in and on the intake screens of the used oil filters. He said if I do the filters myself, to observe any obvious metal bits or shavings on the filter, and notate/record/photograph any such contamination and show it to the dealership which they will note for later if there's any warrantee issues. But I really appreciate the notion that replacing all that fluid every 200, or even 400 hours is an expensive waste, especially in a newer machine where it is not going to wear out so fast.
