gas vs desiel oiling

[daman1]

Multiple drain points are for thorough draining of the oil,for pan removal for example.

I'm planning on purchasing a tractor to do various work on 20 acre property in the mountains I purchased, to include grading of sections ,gravel road,log hauling and splitting,etc.I'd love to get a diesel,for the torque etc.,but this ground is fairly steep in places,with moderate inclines everywhere.Somewhere I read that unlike a gas motor that uses a oil pump for the motor lubrication, a diesel motor uses a "splash"method and one hills the oil can run away from the splash of the crankshaft and starve the motor of oil. Or do I have the gas/diesel methods reversed?Any thoughts or experiences with this concern would be greatly appreciated!

I don't know where you got that info.

Diesels are pressure lubricated for the most part and also use the lube oil as a heat sink for cooling the bearings. etc and the piston crowns with oil jet sprays. Maybe some old stationary engines used splash exclusively but tractors have to oprate up hill and dale so they are designed for a wide set of pitch and roll angles so the lube pump won't get starved for oil.

Jerry:

Ditto that! I've seen a diesel lawnmower engine.. IE.. a stationary engine that used the splas and go method like you mention.. that's the only thing I can think that the OP would / could be meaning.

Mace:

Yep.. I'd love to see them dual pickups myself. noe of my old fords seem to have one..

Well gentlemen, forgive my ignorance...it seems modern tractors are still based upon 1920's technology.

I haven't noticed any Dual oil pick-ups on the engine breakdown diagrams??? Both of them would have to be under oil at all times, or the pump would suck air and be destroyed shortly?Yes, my 4x4 has two drains too..

Many Kubotas have the n-shaped tank. If it didn't have duel pickups then what would be the point of the section of tank that didn't have a pickup? Any oil (including the brand new oil after a change) that got trapped in it would just stay there until either it was drained out or the engine tilts enough for it to drain to the other side.

More oil capacity means cleaner oil and cooler oil. A pretty basic principle of lubrcation system design. I'm still waiting for one of these lubrication system experts to lead me to a CUT or other tractor with dual oil pickups. Just another TBN thread loaded with assumed theory with little or no fact.

What RickB said.

Not so. A certain percentage of oil that has passed through the lubrication system will drain into the side without the pickup, mix with it, then over flow into the side with the pick-up. As time goes on, the difference between the oil in that sump and the oil in the pick-up sump will be impossible to discern.

Well gentlemen, forgive my ignorance...it seems modern tractors are still based upon 1920's technology.

Waiting for a diagram of oil pan and oil pick-up. i am just as puzzeled about the flow of the engine oil from pan to bearings. is it split or a y tube? two pick-ups?

i think it's been pretty well covered that 2 pickups is a rear dog on these tractor engines.

some manuals actually have oil circuit diagrams.. etc..
