2510 50hr. Service

southernAL · Dec 30, 2015

I am nearing my 50hr. Service, so I have been reading in my manual what all needs to be done.
I'm kinda confused on the filters. What is the Orange filter next to my right foot, hst? What about the one underneath, trans? What is the difference in them? I'm guessing you add the fluid where it says "oil" by my right leg? And the drain plug is the plug with Orange paint on it?

Also on page 7-14. Number 7. It says "run the start motor for 10 seconds" what is a start motor?

Sorry for all the questions, just a little confused.

Usually the smaller filter under the operator platform is the HST filter and it's fairly expensive. The other larger filter is the hydro filter, if I'm not mistaken, (not absolutely certain on your model) Kioti. BUT, both should be changed at the 50 hour service. You may need a strong wide jawed channel lock plier for those filters, as well as for your oil filter's first change, they are both bears to get undone on the first service.

Be prepared, we've all experienced the effects of the factory gorilla who puts them on in S. Korea.
Try using a sheet of sandpaper with the grit side facing the filter and then use the channel locks to squeeze the filter and paper to get a good solid grip. Watch your knuckles!

Start motor could be 'starter', everything is translated to English, some better than other words/statements.

Not to worry, we've all scratched our heads on the manual's English...press 2 for Spanish....

Thanks for the reply. Yea I guess I'm just confused on what is the difference in a hydro filter and the trans filter.
The start motor is what kioti is saying to turn on for 10 seconds, then it says turn the engine on for a few minutes. This is in the oil change section. Maybe that means to turn the key to the on position?

There are two filters because one filter is dedicated to the hydro trans only and the other is dedicated to all other hydraulic components such as steering, three point lift, fel, and any remotes that use hydraulic fluid such as a backhoe.

Older manuals are even worse with wrong specs. They just mean start it up and let it run for about ten minutes and then recheck oil levels.

southernAL · Dec 31, 2015

that makes sense, I didn't think about the steering and other hydraulic components. thanks.

Do like I did get the Dealer's maintenance man to come and do it for you. Then sit there and watch him do the maintenance this way you will know what has to be done. 50 hour maintenance is a lot more to it then what it says in the manuals. To be on the safe side and warranty wise have the dealer do it. My 50 hour service was included in the purchase no labour cost and came to the house so all I paid for was the fluids and filters.

southernAL · Dec 31, 2015

That is an idea K man, but the dealer is 2 hours away

I did get him to throw in the filters when I bought the tractor so I have those taken care of, just need fluid. What other things should be done other than whats in the manual?

Everhard · Dec 31, 2015

I did/do my servicing, it's not a big deal. I do have a gear shift version so I've one less filter to deal with. I'd say the manual explains what to do well enough - off the top of my head though (as I'm at work!) aside from oil and filters (don't forget oil in front axle) you have to check the fan belt tension, battery connections, check/clean the rad screen, check rad fluid, check tire pressures, check wheel bolt torq (and all other bolts on the tractor!) grease all grease fittings, check toe-in, check brake pedal free-play, (ensure left and right are set up exactly the same) check clutch free-play.
That's all I can think of without looking at the book.

As my dealer isn't near by and I like to do my own work I'm more then happy to do it myself. I know it's done right to my satisfaction once done.

The filter underneath by the right rear tire is the hardest to get off. I used a chain wrench from Harbor freight Chain Wrench - 20". It crushed the filter a little. I used a 6" extension and my breaker bar.

The others were no trouble.

There are multiple drain plugs for both the engine and hydro system, and they all have crush washers. Most of mine stuck to the bolt or block by paint. Don't lose them. I reused mine. Also they don't need much torque. The setting is in inch/lbs. I used Traveller hydro fluid as the others they spec are unobtanium. And Castrol 15-40 the first time and Rotella the second time. I got the engine oil filter the 2nd time at Napa.

I used a cement/mortar pan to catch the fluids from the many holes (4 or 5). I reused the filtered hydro fluid to change the fluid in my log splitter.

***** Fill the engine thru the orange cap on the side of the engine. NOT the cap on top of the valve cover. ********

southernAL · Jan 3, 2016

Unobtanium? Was that supposed to mean unobtainable? Reason I ask is because the only place I've looked for hydraulic fluid so far is tractor supply. Did you used synthetic hydro fluid and synthetic engine oil?

Unobtanium is just a recent slang for unobtainable anywhere.
I suggest using a high grade UTF, (Universal Tractor Fluid) specked for wet brake systems, which your Kioti has, it can be synthetic, but these are somewhat hard to find, depending on your locale and can also be costly. Kioti does now make it's own spec and named hydraulic fluid, but it is not cheap.
Synthetic oils for the engine are more readily available, Shell Rotella, Diesel oil, 5w-40 and similar grades. Your climate could use the 15-40 Rotella, since you're not in a real cold area.
The front axle can use either gear oil or UTF. If you have more questions about how to get the axle properly drained and refilled just ask.

Yep. Sorry, I shouldn't use slang. In some areas the other fluids might be as close as your tractor store or fuel/lube supplier (some here have said Wal Mart carries it) but I could only find them at high cost online. So I used Tractor Supply UTF that is spec'ed for wet brakes. I don't think they had synthetic.

They had Synthetic Blend oil but since it doesn't specify the % of synthetic I went for the conventional oil. I would pay more for full synthetic if I thought it was needed. And NAPA has an oil filter that is for this engine. He had to order it and I had it the next day.http://www.tractorbynet.com/forums/kioti-owning-operating/165638-filter-cross-reference-help.html

He changed the fuel, air, HST, oil filters. All fluids e.g. , rear axel, front axle, HST/tranny. Grease all nipples on tractor and loader, checked the battery, lights etc etc. Draining front axle took the longest cause it just ooze out and you have to do both sides. Over all I got to see how and what needs changing for my next service of which I will do myself.

Buggs67 · Jan 10, 2016

I didn't change the air, fuel filters or the front axle oil. I didn't think they would need it after 50 hrs.

Mobil Mobilfluid 424, Tractor Hydraulic, 2.5 gal 101189 | Zoro.com
I'm thinking of going with this fluid. I know the owners manual recommends it. This is the cheapest I have seen it. Has anyone ordered for Zoro.com before?

Buggs67 · Jan 12, 2016

I bought grease fittings from them. No problem.

southernAL · Jan 12, 2016

Thanks for that link Buggs. However, I think i'm going to order from zoro. It comes in 2.5 gal container, which is easier to pour, and I figure I can buy 3 which should be plenty enough fluid to change my trans and front axle. I think I will come off cheaper that way since it would be free shipping. Any other thoughts?

handtools · Jan 12, 2016

I've purchased several times from Zoro and have had no problems either. I just did my 50hr service last month, used about 6 gallons of Kioti Lube to change trans and front axle so you should have plenty. I was originally just going to change the filters until I saw the oil that came out changing the hydro filter, a lot dirtier than I expected so off to the dealer for more hydro oil!

southernAL · Jan 12, 2016

thanks handtools, I like that confirmation on changing the fluid instead of just the filters. i've been debating it over and over, but going to just do it all. by the way, nice looking tractor! wish I would have gotten the Backhoe lol

southernAL · Jan 22, 2016

Started on my 50hr Service tonight, got the oil and filter changed(that oil filler port is a slow go). I was looking at all the drain plugs and am a little confused on which plug to pull for the hydro oil. There are 4 plugs it looks like. One in the middle, a large one about under the seat and two smaller ones on both axle sides. Is it just the large one I need to pull to drain the fluid? By the way,i attempted to take the hydro filter off underneath and everyone is right about it being a real pain.
Also, I see the drain plugs for the front axle, but the manual says there is a check plug, which I looked all over the axle and couldn't find. Does this tractor have that check fluid plug?
