DK 45 50 hour service

[seacap04]

I would never consider new oil clean. I have spent too much time and money with hydraulic experts to question their judgement. Think about it, massive amounts of oil are being packaged into small containers. When these filters are changed or cleaned would you want the next container of oil that was packaged? We are lucky in that our oil is prefiltered in the system. Most systems filter the oil returning to the resevoir after it has done its damage.

I work on Hydraulic presses and we always prefilter the oil.

Interesting! Well its too late now for the 50hr service. I can't see myself filtering 5 gallon pails of oil though anyways...
I guess next time I will prefill the hyd. and HST filter though. Thats easy enough to do. I did let it run for 10 minutes before moving though so by then I'd hope all the air bubbles are out of the system.

how does one prefill a filter that is horizontal. I guess you could put a little in , but certainly not fill it up?

I have EXACTLY the same question my Pack Brother...

Inquiring minds want to know...

You prefill your hydraulic filter, that is on the suction side. The HST filter is on the pressure side from what I can see from my repair manual, so that will fill by itself. By not moving your tractor you allow the air to be pushed through the HST by the charge/powersteering pump. DO NOT try to move the tractor until 10 MIN have past. If you have no loader or 3 point hydraulics when you start the tractor then the gear pump did not pick up the fluid, that should happen almost immediatly. If not and you did not prefill your suction filter you may want to and hope you did not junk your gear pump out. That would happen on a tractor with alot of hours on it as a worn gear pump will not pull or suck fluid very well. CJ

You are fine, the systems on our tractors are very well thought out. The oil is actually filtered twice. Once on the way to the gear/charge pump and then on the pressure side on the way to the Hydrostat. Gear pump will tolerate some dirt a Hydrostat will not so the only place to be really concerned is the HST filter and lines/fittings PAST the filter. When I do mine this weekend or next I will prefill my hyd filter and just put a little filtered oil in the HST filter, enough just to soak the element. I have a filter on my oil transfer pump that I will use to trasfer the oil from the buckets. If someone does not have that option just look in the bottom of the bucket with a light before you dump it in to be sure nothing has settled out in the bottom. I will not dump in the last gallon until I check it. I promise you you will be surprised what you can find in there! CJ

+1 The only oil I could get my supplier to confirm that was filtered is the 12000 hour Mobile oil we use in most of our small hydrostat systems. I have actually started looking in the bottom of motor oil containers and was shocked at the crap I found. And yes some brands are worse than others. Mobile has been the best. I just looked into the bottom of a 55 gallon drum of 2000 hour oil we have used and there is actually chunks of paint and other crap visible. CJ

You guys telling me you change hydra fluid at 50 hours?? If so Why?

Dealer told me it was a must to keep the warranty in place but others say no. I'm going to spend the $300 bucks to be sure.

Your dealer is nuts if he said that. There is no reason on Gods green earth to be changing Hydra oil at 50 hours.See pg 7-15 of your owners manual it says filters only. I have worked with this stufffor years and we filter our oil often and rarely change fluid.

The dealer I purchased from said Kioti are "****" when it comes to changing your hydraulic filter or oil at 50 hours. He said it is a closed system and as long as you a careful to keep your couplings clean there is no real way for dirt to enter the system. With this in mind he said there was no reason to change anything until 200 hours if at all.

A second dealer recommended changing the filters only at 150 to 200 hours.

I was also instructed by a mechanic at the dealership to "not fill the filter" as it lays horizontal. This makes sense as most , if not all, of the oil would run out as you attach the filter. The filter says to lubricate the rubber washer, that's all.

Changing just the filter will result in about a 4 litre oil loss as the oil flows freely from the filter input hole. Less oil loss if you are quick or can park on a slope. When you top up the fluid it should fill the filter.

A vertical filter may be different.

If I read my manual correctly I should only change the hydraulic fluid completely at 400 hours.

It appears to be a question of personal comfort and who you want to listen to.

If you were to follow Kioti instruction and changed the filter at 50 hours, then developed a problem at 51 hours, can you say they won't blame your technique or the oil you top up with?

Quality oil from the container should be clean, filter it again, Why?

The tractor is warrantied against a defect in material and workmanship.
Why is it being delivered to me with metal filings in the housing?
If there are metal filings do they not settle and attach to the magnetized drain plug?

I don't have it in front of me, but my CK manual says to change the fluids at 50 hrs, and so did my dealer. After seeing the metal come out on the magnetic drain plugs, it's hard to argue it's not a good thing. I've got $35K into my backyard toy, am I really going to take a gamble over $150 worth of oil? (can't remember exactly how much the oil costs, but I think that's close)

I see that on page 7-15 it does say to change filter ONLY, however on the actual service schedule, page 7-4, look at the note in line 4, a circle with a dot. . In the important index this states categorically MUST BE CHANGED AT 50 HOURS.


Also as stated before, i was confused so i emailed Kioti corporate and got a response that the warranty CAN be voided if all hydraulic fluid isnt changed at 50 hours.

To get any metal/dirt out of the system. CJ

If the dealer says do it then it would be a good idea because he will go to bat for you. I guess if you get WRITTEN permission from KIOTI then you are good to go, unless of course you want to find a different dealer. My manual also states 220+ ft lbs of torque for the front wheels then elsewhere it says 150lbs. Manuals can be wrong. My second oil change I will go longer because of the hour rating of the mobile oil I use. It will also be oil sampled at that time so I know for sure. CJ

Please post that responce in full. I would like to take that to my dealer.

If you have anything in your oil your filters are not working.

 

[grsthegreat]

you know, i looked thru my email file and my printed files for my tractor, and i dont have a copy of this letter. I have copies of all the other questions, like can i use chains on front tires, and can i add a block heater. but nothing on the oil change.

More than likely since i was going to change the oil at 50 hours and i was already going to keep a log book with receipt and hours i didnt even think the letter needed to be kept.

I kept the ones about the chains and block heater encase i had issues later and the dealer said...you arnt supposed to do....., etc.

Its not like someone will chastise you for changing fluids MORE often.

You can contact Kioti corporate yourself by going to the kioti website and hit contact us.

they will ask for your tractors serial number, dealer info etc. but there VERY good at getting back to you.

Ive contacted them about 4-5 times on some issues/questions and they have always responded. I one of those guys that like to have a potential issue answered in writing on company letterhead.

The owners manual for the DS 4110 HS Maintenance Schedule Chart page 7-4 line 4 Transmission fluid Check at 10 hours, Change at 400 hours.

Page 7-14 "transmission fluid should be changed if it is contaminated or after the transmission is serviced or every 400 hours" and "When changing the transmission fluid, make sure to change the fluid filter".

Is changing the filter "transmission service"?
Is topping up with fluid "transmission service"?

and "replace the filter only at initial 50 hours and every 200 hours operation afterward"

That's three filters in 400 hours. Six if you are HST. (and I don't mean the Canadian tax)

The DS 4110 doesn't come with HST option but it tells me to change that filter at the same time.

Are these group specific manuals, model specific manuals, or generic manuals?

Kioti will need to get less ambiguous if the service schedule in our owners manuals are to form part of denying the warranty claim.

Whatever drives your tractor CJ. I don't need WRITTEN permission from anybody. Tell me this, How many other tractor brands say to change Hydra oil at 50 hours???...... NONE.:confused2:
