kioti grease fittings

[chuck172]

If the lever on the gun moved, then the zerk took grease. You just need a couple of pumps on those zerks each 50 hours

Then I'm good, thanks.

I received the locknlube fitting, works great. Does just what it supposed to. I tried the axle pivot fittings. I was able to pump the gun with the no grease spilling. The locknlube held tight. I don't know if it took any grease. I pumped about 5 strokes, really had lots of pressure. I thought the hose would burst. I tried loading and unloading the joint with the loader raising the front of the machine. No difference.

Mine was very hard to pump grease in the first few pumps but after that it started to take it much better. Now its not any harder than the other fittings.

If it hadn't been greased in a while, it's possible that dried grease or crud was blocking the passage beyond the actual zerk. So the zerk works but it takes extra pressure to move the inspisated old grease out of the passage before new grease can get in. I use one of those oil injector thingies with a hammer if a zerk won't take grease. Generally that does the trick. If it doesn't I remove the zerk and soak it in diesel and unless the zerk is damaged, that usually cleans it effectively. I have "repaired" multiple zerks on my DK over the years but I think I've only actually had to replace one and that was on my backhoe.

Believe me I understand this thought process. I just wanted to let him know he wasn't alone in getting grease in the first time. Many folks don't understand as much about the mechanics of things and need a slight assurance they are going to be OK.

Just for the record I normally use an air power grease pump from the old garage but on a new machine I prefer to use the hand pump the first time or two. Seems I always end up with one or two zerks that want to fight and when that big barrel gun starts flowing it can make a mess real quick!

Just to reassure anyone reading this thread about the kioti zerk thread size, chuck172 is right. But I'd like to elaborate a bit. The thread size is 1/8 28 BSPT (British Standard Pipe Thread), A confusion we may run into here is the lack of labeling from manufacturers. They don't always include the "T" in BSPT. The tap, die, or zerk will sometimes just be labeled BSP. Now, BSPT is a tapered thread, like most pipe threads are. Very very similar in size to NPT, but not quite, which is where much of the confusion originates from.

All would be fine if there were only one type of BSP thread. But alas, such is not the case. There is also a BSPP (British Standard Pipe Parallel), that is also sometimes just labelled BSP. This thread is straight, and will not quite fit our application. It is too wide at the beginning of the thread to get it easily started.

Further confusion is added when providers call the thread "BSP straight" which implies BSPP, But sometimes shows up to my shop as BSPT, and other times it shows up as BSPP :confused3:. More confusion still, BSPT male will actually fit into BSPP female, albeit slightly sloppy start of thread. But BSPP will not fit into BSPT.


All of that said, at the end of the day, what we need is 1/8 - 28 BSPT. You can find them on Ebay and a few other places online, but, don't always trust their labeling. Zerks are cheap, though, so order a few kinds if you are unsure.

This thread size is true for my 2014 Kioti DK45HSE, the KL401 loader and the KB2485 backhoe. anyway.

Thank you for providing some insight into this.. and the question in my mind remains, why in heck does a metric tractor made in a country that embraces the metric system, (Korea) and is marketed and sold in America as Kioti, a country that embraces some ancient system based on some long dead kings foot. we have to hunt for some ancient ambigious pipe thread popular in a country that is now metric itself... Pretty interesting huh... I am not sure I understand.:confused3:

BSP threads have been adopted internationally as the standard for pipe mating, with the exception of one country, The USA. We still use NPT (National Pipe Thread). We never hear of any metric pipe thread, only NPT, or BSP. Now, there is plenty of metric threads out there, and many may be asking why we see metric grease zerks if there is no metric pipe thread. Those metric grease zerks are not being looked at like a pipe fitting by their manufactures, more like a metric bolt thread. Which is fine, but traditionally, a grease zerk is viewed as a pipe connection. For all intents and purposes, Metric pipe thread does not exist. So with that in mind, it now makes perfect sense that our Korean tractors grease zerk threads are BSPT. In fact, it makes the most sense, internationally speaking. I imaging 10 years down the road, we will be able to buy an assortment box of BSPT grease zerks at our local stores. Good luck finding one now.

I'd like to add that metric pipe thread does exist, but it's sparsely used in spots around he word, and is of no standard.

So does this look like the right fitting?

The description down below, in that link, says BSPT (british standard pipe thread) which is the correct indication. The picture of that zerk also looks correct, note the slight taper seen. The "str" in that zerks title is just indicating it is a straight grease zerk, vs a 45 or 90 degree zerk. And seeing that it's coming from Germany tells us its pobably BSPT, as Germany uses BSPT as their standard pipe thread. I'd say it's good to go and would purchase one package, just to be sure it is what it says it is.

It’s also interesting to note that the zerks may have been installed in our tractors at the factory by means of a self-threading zerk to save money, which makes sense. These self-threading zerks can be purchased from places like Mcmaster-Carr (not sure if they carry the right size), but it would not be any more beneficial. We can just use regular thread-in zerks, because the threads have already been established in the hole when the factory installed the zerk for the first time. This may be why the correct 1/8 – 28 BSPT zerk is still just slightly tight in the hole the first time, like putting a pipe nipple in a freshly tapped hole for the first time.

BSPT = British Standard Pipe Tapered.
BSPP = British Standard Pipe Parallel.

Tapered and parallel refer to the thread profile.

Yes, that is correct

They are a lot cheaper than that from a Kioti dealer.

Zoro is Grainger's online discount division established to compete with some of the other online retailers. Their product offerings are much more limited than Grainger itself, but what they do have is cheaper.

My dealer said they are on backorder. And I can't believe they'll charge $3.22 for a 10 pack. They don't have anything under $5. I paid $1 each at a local auto parts store but it didn't fit.

I didn't get that they were 10 for $3.22. My bad. I stock the Kioti part number, and yes, they go on backorder time to time, but I try to keep them on hand.

I purchased mine from zoro, the 90, 45, and str. all were in packs of 10, all fit great. I've also purchased them on ebay from zerksplus. Both are great deals.
