Kubota zerk grease fitting size

[gwdixon]

Does anyone know the grease fitting size for a Kubota Zerk? The research I've done indicates it is 8MM x 1.25 but would like verification.

Also, is the size universal across the Kubota line? My three tractors (M7040, L48, BX2200) and a neighbor's L5240 all need a zerk or two (or three).

Messick's shows "Kubota GREASE FITTING Part #K5221-71280" $2.33 ea. There are no details and no other Zerk listings on their site.

I think you will find the ones on the Loader to be SAE not metric thread, those on the tractor are metric.

That stinks.

Thanks. I do have an assortment collection of Zerks and tried all that were close. None of the ones, neither SAE nor metric, fit. That is why I asked the question.

Looking for specific size(s).

Kioti has some very weird sizes I here. English thread.

There's SAE, metric, and Whitworth, (British). SAE is; Society of Automotive Engineers.

The FEL zerks on my L4240 are 1/4-28. I haven't needed to change any on the tractor, but have heard they are metric. Go figure. :confused3:

Just changed out some zerks on my 2620 as well as the blower and I believe they are 8 mm. I bought a box of them off Amazon (had both SAE and metric) and matched up threads for the replacement. When inserting new zerk I was cautious to make sure I didn't cross thread or get SAE into metric or visa-versa. Some of the original zerks were defective in that the springs and balls were missing. I am not sure about the FEL or the BH. I'm sure I'll find out before too long.

When I bought my Kubota L4400, I bought an assortment of Zerks for my make and model at the parts department at my Dealer. The assortment included a list of the zerks, their sizes and the location and size of where the zerks were used. I don't know if Kubota still does this because it will be 2 years in July when I purchased my tractor.

I think creekbend has the answer.

My Kubota dealer replied to my e-mail about Zerk sizes and recommended going to Harbor Freight and buying their metric and SAE assortment. There is no standardization to Kubota grease fittings.

50 Piece Grease Fitting Assortment

32 Piece Metric Grease Fittings

Seeing as how the dealer charges $2+ for each Zerk, it allows the HF fitting assortment to make sense.

Thanks for all of your responses.
