I don't get it.
Doing my 400 hr. oil change on the '12 L3940HSTC. Drained oil, replaced drain plugs, refilled w/Rotella 5W-50 ('HD diesel') synth engine oil, NAPA Gold 1311 filter.
Also replaced fuel element. Turned fuel cock off to remove, used new Kubota element, cleaned bowl, replaced all including o-ring, turned fuel cock back on, (straight up). (The element goes in with the opening at the top and the solid end resting on the spring in the bottom of the bowl, right?) Opened air vent and started engine to bleed fuel line - it fired right up beautiful like it does with fresh oil - ran it 30 sec.s and shut it off, then closed air vent.
Went and did lube on FEL and backhoe. When done with that, I started engine. It fired up OK but then rpms came down, and it ran erratically, and eventually stalled out. Checked everything, oil filter is tight, fuel bowl is seated correctly and tight, nothing leaking. The motor re-fired a few more times, and I lifted the throttle a bit, rpms came up briefly but then went down, it ran poorly and stalled out again. During this, I noticed the oil pressure Intellipanel light on, warning me, supposedly, of low oil pressure - it beeped at me a couple of times to alert me. Huh? Checked dipstick again, it's got all the nice new oil it's supposed to have, at the right level. Now the thing won't even start, just getting a few chugs out of it while I'm leaning on the starter. Decided to come on here and post this before I burn that up.
How can I have a low oil pressure idiot light when it's loaded with all new oil?
The way it runs - or doesn't - reminds me of one time when I forgot to turn the fuel cock back on, and it starved for fuel. (There's plenty in it.)
Trying to do the scheduled maintenance and be ready for the lousy weather. Now it won't run at all. WTF is happening here?
