Anyone know the thread size of Kubota grease fittings?

[Frankenkubota]

This place is a wealth of information, thx to all. Rainy morning in NC.

I called my local dealer about these zerks grease fittings and they didn’t know either! I broke mine 2 weeks ago. My plan is to remove the broken fitting with an ez out. ( Ive tried ez outs maybe 10 times in the past, never worked, end up with a broken tool in a old rusty brake cylinder!). My tractor is only 6 months old so maybe it will cooperate.....maybe. I will steel a good fitting from the adjacent point on the fel, I have 4 of the same on each side, Confirm that it fits where the broken one was removed and then take that known good one to the dealer, along with my broken fitting, see if they can match them up. He’s says, no problem. Hmmmmm

Side note. After 6 months, every fitting was loose, except the one that broke, ha! Might wanna check your fittings.

I’ve been waiting 2 weeks to do the job because.....i can not get to my tractor unless I’m completely naked or wearing hip boots. Hmmmmm

I bought a good sized piece of land last year, big new tractor, bucket list stuff. I had about 1 acre scrapped off and flattened for small house and shop. In 1 year I’ve got footings and block, that’s it. Ever hear of Ga. red clay. Ga has no patents on red clay. It’s been raining pretty steady in NC for years. Ive been here 40 years and as retired geezer, golfer and outdoors kinda guy, I pay a lot more attention to weather than the Starbucks crowd. I’m a semi expert on incessant rain as I lived in Oregon for 7 years so.......been there, done that. As far as rain, Carolina is simply Oregon with an accent, except Oregon has spectacular summers, albeit only 7 weeks long.

About 6 months ago, I started keeping track of the rain. It rains in central NC about every 40-50 hours, on average. It was not like that in the past. Once in a great while we will get 5-6 days with out rain, more often 5-6 days of rain in a row. The orange mud never drys out....never. I can’t believe this placed perked, the tire ruts hold water for weeks! I’m told the pottery capitol of the USA is just up the road, unlimited free orange clay.

I literary can not walk to my tractor without being overcome with this mud. You southerners know what I’m talking about. I grew up in Wisconsin, we didn’t have orange clay.

I hope to have good news re the zerks but until it stops raining, I wait and wait and wait.

And anybody says just 1 word about drought and I’m goin postal!

I broke a zerk fitting on the LA 1154 front end loader on my Kubota M7060HD12. Who knew there are a million different sizes of zerks? It looked exactly like a metric M8x1,mwhich will start in the hole but does not fit. Turns out it is a 5/16"-22 BSF fitting. You will not find those in any of the grab-bag zerk kits. I bought some from McMaster-Carr.

You would think tractor mfgs would stick to one or two common size zerks?

Frankenkubota - Since zerks are not tightened very much compared to other fasteners, you should have an easy time removing it with an easy out. Since your loader is an LA1056 and mine is an LA1154, your zerk may also be M8x1.25. If so, the socket size for that zerk is 9mm. Put on those hip boots and get 'er done. Good luck!

Re Zerks, (grease fittings)---
Got lucky once at a gov't surplus sale.
There staring at me was a small parts tray, the kind with some 50 or so dividers, with hundreds of assorted zerks!
Knowing I'd never in my life use that many I split the assortment into 2 batches and sold the 1/2 for what I paid for the lot.

Oh, and my initial cost was a crazy $10.00 so I ended up paying couple pennies per zerk.
LOL, the storage tray itself usually sells in the $20-30. range.

Sweet deal!

Your comment re common sized fittings made me laugh. Couldn’t agree more but....don’t hold your breath. I comment only because I just receives a shipment from Messicks. All together 5 “oil” filters, I have 2 kubota diesels.. All good

I’m building a house and everything is either in storage or lost. I went to Harbor Freight and bought a “universal” oil filter wrench set. The kind you use with a 3/8 drive, about 5-6 sizes. Yup, none fit. My strap wrenches are buried so back to HF.

I was in manufacturing for a long time. It’s called service parts, very very lucrative. I don’t blame them. I wonder if there is an “kubota” filter wrench.

I went with an assortment also, found a set 110 pc. metric and 110 pc. SAE, from EBAY.

Ok, here we go

I have a MX5800 tractor with the LA1065 fel. 6 months old. Broke a zerks/grease fitting on the very front of the loader where it attaches to the bucket, 4 on each side. Careful, fittings on the arms different size. I知 sure it broke because it was the lowest and I probably didn稚 remove the grease gun just right. Next time the loader goes up! 10 mm socket on these fittings.

The photo shows the broken fitting on the ez out, a known oem factory fitting from the adjacent location that fit where the broken one came out and the new fitting from the Kubota dealer. I noticed they appear different, less threads, a little different look although it worked. Also 10mm.

Now for the editorial comments.

All my fel fittings were loose except the one that broke, I mean finger loose! It figures, the one that broke was too tight. Neighbor and I fought it for 1 hour, almost got the torch out and had already decided to pull the pin if I had to. It was way way too tight, imho.

68 cents for a new one, I splurged and got 3!

While ranting about things being too tight. The hydraulic filter changed on my 50 hour service was so tight I almost had to drive a screwdriver thru the body.

Both were done at the factory.

Side note, while in school I was a machine shop inspector in a uaw shop, big big place, machined auto parts. I致e also worked in management in manufacturing.. I know what goes on on 2nd and 3rd shift. If I told you, you simply wouldn稚 believe me.

Reminds me of getting new tires. Yea Ive installed tires etc and I don稚 think I have ever even heard anyone talking about calibrating the air guns, windy guns, much less actually do it.

So, imho the 1 zerks was way too tight and the others loose as a goose. The filter was also way too tight, only 50 hours so it was done at the factory.

Check your grease fittings and good luck.
