75546-68110 hydraulic outlet block

[TheOldHokie]

This block fits a number of older L series (L2500, L2600, L3000, and more) Kubota wants a modest $325 for it.

My shamelessly reverse engineered knockoff costs "just a little bit" less

Cheater, it's not round!

Cheater, it's not round!

You know I dont cheat Wolfey

The round piece is the $45 blockoff plate that I used for reference. The "genuine Kubota" outlet blocks come in multiple versions all rectanguler because you can not' fit the ports into a round one. I did take the liberty of making the gland fit a -111 oring

Very nice job sir!

Forgive my ignorance, is that a reference to what I "believe" are the O-rings for the ORB style fittings?

Either way, nice job!!!

Its a reference to the face seals on the block. The long sordid story:

When I measured the OD of the glands on the OEM cover I got .61/.62 which is very close to 16mm. Depth was .070/.075 which led me to concluded the factory orings were standard 11x2.5 mm o-rings. I decided to use a 5/8 endmill to cut the glands and substitute a AS568-111 imperial oring. When I went to send it out I discovered I did not have any -111 o-rings on hand - WTF!!

I dont keep metric rings on hand but I did have a small assortment in a plastic case I purchssed years ago. I dug it out and alas no 11x2.5 rings. Instead it had 10.8 x 2.4 - WTF!

Desparate to get the block shipped I test fit one of the 10.8 orings. It seemed to fit well with plenty of squeeze so out it went. We shall see how that works when the customer puts it on.

Now for the obligatory educational part. That "oddball" metric size was bothering the hell out of me. Google is pretty good if you ask the right question and it turns out the Japanese have thier own oring standard (JIS) and 10.8 x 2 4 mm is a standard size. That leads me to conclude Kubota most likely uses JIS rather than ISO/DIN orings. Who would have guessed

I actually knew they used somethinhg odd, Just didn't know what to call it, as most o-rings in at least the older kubota's are not standard sizes.

Now we know - they use Japanese Industrial Standard orings in some applications.

I know Kubota uses the JIS standard in much of their manufacturing process. What I did not know is that JIS has a unique standard for oring sizes.

I learned something new with that little project and that's always a plus.
