2 questions, first are the fittings on the B and Kubota equipment metric threads cause greasing up the FEL and MMM I found several gone and need replaced. Also why will my grease gun fit tight one some and others wont even stay in the nozzle? They seem to be smaller.

I got these for my BX:
However, for the bucket dump pin, I had to get a longer fitting since the grease coupler would bottom out on the cup shaped recess on the pin end where the fitting is centered.
These fittings are hard for the coupler to hold on to. Supposedly the coupler has some adjustment.

They are probably metric. If you can get to the Kubota website and the illustrated parts list you can find the fittings in question and order them from your dealer. Additionally you can see if they are all the same part number used in different locations. Then buy one or a package at the dealer and figure out the thread size if you want to get them at local supply shop. I don’t recall that the dealer price was very high at all. I think they even had them in stock.
I do recall that on my L185 there were at least two part numbers involved that they listed for the different location but I can’t recall if that was straight and 45 degree or different sizes.
If you need help in getting the part numbers let us know. I recall that you’re somewhat reluctant on computer use but may be confusing you with another poster.
Edit = forgot to say about the fitting being tight or loose on gun coupler. I generally see that as dirt/grease buildup that does not let coupler fit on correctly. Clean the up of the dried up crud on outside and see if it works better. I guess the can be worn down but have doubts that happens frequently.
I try to keep mine covered up with caps t keep them a bit cleaner and easier to find since the color stands out.

Tractor fittings wlll be metric like M6 x !.0,or 1/8 BSP
USA made loaders and decks will be SAE,like 1/4x28NF,or 1/8NPT,etc.
Good Luck!

I'm a big fan of the LockN'Lubes. No adjustment needed but there are some tight spots they don't fit into. Fortunately, a while back they released a right angle adapter, which basically works like a standard fitting, but it allows you to access areas that you would otherwise be unable to.

Skeets, you're welcome. It is amazing how sometimes just a bit of simple information escapes the masses, and can cause so much frustration.

Many times the zerks are not installed all the way. If they were not checked at the initial PDI, then they need to be checked(screwed down).
Grease-zerks are sold in “kits” with varying-sizes on both Metric and SAE threads. Some thread are “machine” (straight-sided) but most are “pipe” (expanding) threads. Those which appear to not be fully tightened-down... MAY be improper substitutes which have been installed (SAE into Metric or Metric into SAE threaded fittings.).
Best solution? Purchase “Assortment kits” in both Metric and SAE and carefully screw the replacements in by-hand before final tightening to be certain of the threads. And note the size of the “ball” or “socket” so you don’t have to constantly adjust your gun-nozzle/collet.
The problem with Kubota tractors/Loaders often is the tractors are made in Japan and the Loaders in USA so therefore the “mix” of Metric/SAE.
Hope this helps.

Lol after all these years (decades!) of swearing at my grease gun tip (WHY won't it fit? Why too tight? Why does it leak? Why working now and not before?) I finally stumbled on the adjustment mechanism last year.
Always works now!
On my 80s M5030DT loader the grease fittings were British pipe taper. Newer B26 lost a 1/8” fitting on the ssqa wedge pin. Tried metric but no go. Used SAE and could start but felt like it was crossing. Tighten anyway and worked. Some sizes the difference between SAE and British pipe slight. Have large assortment of both SAE and metric. British assortments are expensive. Best source was the dealer.
some of the hydraulic threaded connectors are also British pipe so be careful.

These Kubtoas often use JIC for Hydraulic connections, so be careful. With JIC (NorthAmerican), BSP (British), GAZ (French), DIN (German), JIS (Japanese).... and then each has several sub-types...it can get tricky.
Here’s a manual which can help identify what type you may encounter: https://sircoindustrialerie.com/pdf/thread-types.pdf

Thanks for the information video. Have been greasing tractors since a kid and NEVER knew grease tips were adjustable.

Just throwing this out there for consideration. I am 74 and have have worked around machinery for literally 64 of those years. (Family Business ... child labor was a necessity back then.... and it was fun and kept me and my younger brothers out of trouble..
and we learned a lot)
Well... with that being said .... I ain't as agile as I used to be so greasing my "stuff" became a little arduous. So some time ago, to make things simpler, I invested in a Lincoln pneumatic grease gun and a 3/4" thick 4'x5' rubber mat (my neighbor gave it to me) to lay across equipment (Kubota RCK mower deck). The mat cut down on belly, chest and arm bruising when I serviced the deck while still on the tractor.
It also helped when I would visit a doctor I was not constantly explaining where I got all the bruises in the first place.
Life was good! minimal body bruising and all I had to do was pull the grease gun trigger .... no more pumping the old grease gun!
The above helped immensely... but being four days older than dirt I still got super sore! The best way to explain it is; Imagine an old fart on his belly, on a rubber mat, with a kick butt one handed grease gun in one hand and the business end of the whip hose in the other trying to grease a RCK60-24B MMM while installed under a B2410. There are 14 grease fittings on that mower deck and drive line. 7 of the 14 are buried under the tractor centerline with all the MMM mounting lift brackets dead balls in the way. Needless to say it gets quite crowded under there real quick and the contortions I had to get into to get to the zerks goes without saying.
My chiropractor's wife loves me... she said I single handedly put her youngest kid through undergrad.... I figured out a way to make more room under the tractor, free up one hand and cut down on the cuss'n tremendously.
My wife and I are retired and she's always wanting to "help". Now... don't get ahead of yourself I did not put her under the tractor. Besides she won't fit. (She does not read OTT either). What I did was buy a 48" grease gun whip, a box of small latex shop gloves and a shop apron for her to wear. Now having both hands free I can slip under the tractor to do my thing. My wife stands beside the tractor squeezing the grease gun trigger as I request it. Not Bad Ehhhh!

New need: QUALITY Zerk Caps and grease fitting kit. Someone have a good link to them???
(The Kubota looks great but I'm thinking there are more fitting options so the kit is more generic and works with other stuff also, plus some hard-to-reach fittings can be replaced with non-OEM fittings.)
