The M18 is a Z600, but I think that's the same block with bigger cylinders. Someone's replaced the stick, but no big deal.

Re: Oil pan for Universal Diesel

... and that is why I refinished the pan on my M25.

Would anyone like to buy a Kubota PN: 15371-01614? that will fit an M25 or M25XP? - $30

Re: Oil pan for Universal Diesel

Just like oil pans in cars, the same engine might have several different pans to fit different chassis. I don't think Universal had special pans made for their engines, the differences are to fit different tractors or equipment. As far as I know, the Z500 (5411) was only used in the B5100 tractor, but the D950 (M25XP) was used in about 100 different applications. Some of those had different pans, sticks,etc. None of that is any reason to pay Universals exorbitant prices. If we keep paying them, they'll keep charging.

Re: Oil pan for Universal Diesel

Because I pulled the oil pan with the intent of replacing it last fall;

Universal Marine Oil Pan - 4 qts to full;
Note the drain in the CENTER, and the dipstick port brazed onto the side.

Kubota Oil Pan - PN: 15371-01614 -3qts to full;
Note the drain on the SIDE and no port for the dipstick.

Side by side comparison;
Note how much shallower the Kubota drain pan is...

I ended up refinishing the original oil pan (sanded the rust, neutralized it with "The Must for Rust," filled in pinholes with JB Weld, and repainted), and re-installed.

There's nothing wrong with a drain plug on a marine diesel. It's just that on a lot boats you can't get a pan under the engine to use it. In fact many engines have a hose connected to it to drain through. The Kubota pan is perfectly fine. Same thing with any other parts you may need. The only parts you can't get from Kubota are the exhaust manifold and raw water pump.
I'm in Muskegon and shop at Torreson all the time and have friends who work there, but I don't buy engine parts from them.

Re: Oil pan for Universal Diesel

I replaced my M25xp oil pan with one from Kubota ( $45.00 at the local dealer. ) and just use the dipstick hole on the port side, there's room to get at the stick and you can easily braze on an extension to the stick to make it easier. There's no reason for marine engines not to have a drain hole and all that I've seen have one. In my application I can drain the oil under the engine, I've drilled a small hole in the edge of the drain plug and safety wire it. oops, just noticed I replied to a year old thread, what year is it?

Yes, the Universal pan on my 5424 has a drain too.

I think the regulation in question concerns oil and fuel tanks, which shouldn't have a drain that could potentially contaminate the bilge. Whether or not a sump is a tank, you could debate.

Re: Oil pan for Universal Diesel

The dip stick is on the left when looking at flywheel. The reason that this modification is required is that the alternator would prevent dip stick use if the modification were not made.

I have a tractor oil pan, and am considering adding a sight glass from a motorcycle, instead of, or in addition to, the dip stick.

Re: Oil pan for Universal Diesel

The dipstick addition makes sense. Mine dipstick is on the left when facing the front of the engine.

Re: Oil pan for Universal Diesel

The oil pan from Kubota is modified by adding a 90 degree barb (I believe that it is a 3/8") to where the plug goes, and by brazing a dip stick fitting to the right side of the pan.
