Kioti maintenance intervals

[Highbeam]

50 hours? I have been doing 100 hour changes on my CK30. Uh-oh, is it really supposed to be 50? That's awfully short.

I just rolled over 1000 hours yesterday. Dang thing has the most consistent oil level of anything I've ever owned. It stays exactly the same, right at the notch, over the 100 hours but does get black.

My OM says 100 hours, and the sticker on the side panel says 75 hours for
engine oil change. I stick to the "standard" interval of 100 hr for oil and
filter.

Congrats on hitting 1000 hrs!. My 05 CK30 is only at 306 hrs, and has
been flawless (including the FEL).

theres only an initial 50 hour change....when the tractor is new. after that it follows the schedule

I was remembering the 50hr service but you guys are right about subsequent changes being at 100. Still, that equates roughly to changing car motor oil at about 2500-3000 miles which was recommended in the past but few modern cars carry those recommendations. Mercedes and BMW are 10,000 miles with synthetic. Mazda is 5000 miles with dino. Why have the tractor manufacturers not kept pace as oils have improved? And, what's with changing the hydraulic fluid every 400hrs (approx 10,000 miles on a car) when cars these days routinely go three to ten times that long before changing transmission fluid? :confused2:

I wish the tractor companies would man up and publish more realistic and evidence based recommendations rather than CYA based standards. In this day and age it is a crime to be dumping gallons of partially used oil products. Diesel truckers certainly do not change oil every 100 hours (2500 miles) or transmission fluid every month or two. Why not use the standards of the trucking industry for diesel/transmission maintenance?

Well IT, the benz and BMW automakers aren't using prechambers, mechanical injection pumps, and pushrod diesel engines. I think you would find that when they were using that ancient tech that the fluid change intervals were much shorter.

Maybe the better question is why don't tractors use the modern technology which would allow for extended intervals? I would rather change oil than have to diagnose and replace a zillion sensors and computers. Quite happy with this old school tech.

Even my old 1998 chevy pickup required 3000 mile oil change intervals with its gasoline OBD2 (clean) engine. Current diesel truck requires 5000 mile intervals. Hard to compare a working engine with a light duty car.

Highbeam, if the oil change intervals are guided by the level of technology and are based on oil analyses then I don't have trouble with the recommendations. I'd bet the intervals are not so scientific or rational however with our tractors. Certainly older diesel long haul trucks had much longer change intervals with what must have been older technology engines.

My diesel VW, the 50 state legal, common-rail diesel engine, has a 10K oil change interval. That said, I'm happy with my tractor. The VW is uber technical. I've lived with and worked on diesels most of my life in cars, tractors, boats and ships, but I'm afraid to touch the VW. For my tractor I want something I can trouble shoot and fix without having to trailer-up and head for a dealer. I'll gladly put up with the oil change interval if that is the price. That said I'm all for the tractor community getting scientific about their intervals. I suspect that part of their problem is that our machines are used in so many different ways. They probably assume a worst case dirty air heavy load environment for their recommendations.

Can't compare to a long haul truck engine. Those engines are in trucks that seldom stop moving so the engine oil stays hot and doesn't have a chance to accumulate water, which creates acids which are bad. The oil has to work a lot harder per mile in a short trip type vehicle.

Maybe BMW and for sure benz made 4 and 5 cylinder non-turbo diesels with similar tech as our tractors in the late 70s. What was the recommended interval for those cars?

I doubt that much analysis was done to determine that 100 hour interval. I also believe that Kioti would take a conservative approach and look at the most abusive 100 hours possible which is likely much different than most users' 100 hours. You've got to admit that these tractors are subjected to a huge range of expected operating styles from Yukon cold to equator hot and from PTO all day to short 10 minute strolls to the mailbox.

I am more "upset" with the 400 hour dumping of the whole hydro fluid reservoir. That seems wasteful.

My CK is due for engine oil and hydro oil change right now, well actually about 6 hours ago.

Good points ERE and Highbeam. I suppose that as my warranty expires at the end of the summer that I can then put my money where my mouth/keyboard is and choose a different change interval. I may send off an oil analysis next time just to get some data specific to my tractor and use pattern. I wonder if there is a similar type of hydraulic fluid analysis available?

good question...id like to know that also.
