Oil & Fuel Oil Level Mystery

[bill in ny]

newbury, he's changing the engine oil.

gwdixon said, "Kubota fills new tractors to the midpoint of the dipstick anyway."

and dex3361 said, "L4400 (134 cubic inch)with a filter is 8 Qts. I think it is the same engine as in the L4200"

I don't know if it's the same engine as the L4400, but it is the same cubic inch displacement.
The 6.3 quarts that the manual states would put the level right about midpoint between the low and full marks.
So maybe that midpoint is where Kubota means when they say the crankcase capacity is 6.3 quarts.

Didn't measure the oil that I drained out, but it was right up to the full mark and there was no indication of foaming on the dipstick.

So, I think that I will bring the level up to the full mark.
I would think that Kubota would not make the level at the full mark so high that the rods would contact the oil and cause foaming.

Thanks,
Arky

My 2 cents (how come we can't make that mark anymore?)

Is it the right stick - part number - compare to friend or book...
or right length - stop to marks (not between hi/low)- compare to friend!

In my experience - it's highly likely that things like measures (that vary even within English) can be mistranslated - misconverted - and then printed in 'our' version of the book

Watch overfill closesly - check for any aeration - air entrapment - foamy, volume rises after running - I ruined a gas bearing that way once.

Extra quarts are sacrificed to the the oil gods. If they are not appeased, they can possess your mind. Then you will start posting to the "what kind of oil is best?" threads. Beware.

(Ignore the above, believe your dipstick)

Seeing as how you breached the subject, what kind of oil is the best?

RoyalSoil Magenta Eco-Synthetic 8W-45. At $16/qt, it's worth the extra protection.

And if you don't agree, you're worse than ******.

Yes, I compared part numbers and length from stop to both the high and low marks with another L4200 owner; they are identical.

And like I said, the old oil was up to the full mark with no sign of foaming on the dipstick when checking immediately after running a while.

With the dipstick being right (and it appears to be), there should be no problem with crankshaft causing foaming at the full mark.

My conclusion, (though it's just my best guess), is that Kubota's crankcase capacity is meant to be at a level midway between the high and low marks. At any rate, that's where 6.3 quarts puts the level.

Ask the technical department at Kubota.
Maybe there is incorrect information in their manual (typo) that needs to be addressed.
My Kubota Dealer claims they find typos all the time in the parts manuals.
I just found a conflicting electrical issue between my owners manual, WSM, and Illustrated Parts Manual that I addressed to Kubota at the site listed below:

A consideration. Factory may bring to mid point on dipstick. A dealer may have a mechanic that tops off all fluids before delivery.

Thats exactly what happens.

My dealer said that Kubota considers mid point on the dip stick full. When he preps new ones they add oil to the full mark.

He has had customers in the past pull the dip stick and make comments it was low on oil.

On a side note. I've rarely seen where the actual capacity and the recommended capacity are the same.

I just changed the oil and filter in a Kubota L4200 that I recently acquired.
The owners manual states that, with the filter, the oil capacity is 6.3 quarts.
I drained the oil, changed the filter, added 6 quarts and then ran the engine for a few minutes.
When I checked the oil level it was just a little above the low mark.
There is 2&3/8" between the low and full marks.
After adding another full quart for a total of seven, the level is still 1/2" below the full mark. The tractor is parked level and I have verified that it has the correct dipstick.
Not sure now if I should drain some out or add some.
What I do know for sure is that it has 7 quarts in it and still reads 1/2" below the full mark even after sitting overnight, and that the owners manual states that 6.3 quarts is the capacity.
Anyone have any ideas why it's still reading low ?

Thanks,
Arky

Believe your dipstick, and remember the crankcase has a breather tube to atmospere to prevent pressure

building up in the sump and causing an engine to explode.


The crankcase oil will go to steam as well evaporating the oil while it is heated to a cetain extent.


Having a filled crankcase will do no harm as long as the crankcase breather is not plugged or obstructed.



Baron Von Diesel did not realise this and he was almost killed when they were testing his engine-he did

not have a crankcase breather in the test engine-whoops
