Help identifying #1 cylinder on BX2350

[fish6942]

Hello All -

I'm wanting to do the valve clearance check and need confirmation on which is the #1 cylinder.

I have the WSM (page attached) that states the #1 cylinder is nearest the gear case. Are they referring to the fan/water pump end of the engine as being the gear case? The BX has the engine installed with the fan end facing rearwards and the flywheel facing forward towards the front bumper.

Thank you!!

Check the General Section, first few pages, for a picture of the cylinder number ID.
A different BX series (1870,2370,2670) seems to say the same as your manual, but the picture looks like #1 is closest to the fan.

Yes, the engine is mounted backwards. The #1 is where the fan is.

Thanks guys! I don’t believe my WSM has that nice cylinder layout diagram, that would have been helpful.

Also vaguely referencing a non engine part of the tractor is not very clear. Saying nearest the fan or thermostat housing would have been much more clear.

On all Kubota engines, the flywheel is mounted on the rear of the engine.

Yeah, I'd say you are absolutely right. Take this lightly, please, but all engines have the flywheel mounted on the rear unless they put the transmission in the front ...

The front of an engine is always the Front no matter which end the transmission is connected to.

Uhhh... OK, educate me. If the rear is not always where the flywheel attaches to the crankshaft then exactly what officially identifies the "front?"

What about the engine on a combine harvester? They're mounted transverse on the unit just like my Toyota RAV4. The number one cylinder is on the end opposite the flywheel by the water pump and vibration damper pulley.

The Kubota BX series has the transmission being powered from the FRONT of the engine, yet the flywheel is mounted to the REAR of the engine.

Education not complete: The silly confusing situation is just fine with me. Take that as a given. Now, who gets to decide which is the front and which is the rear and what was their criteria for the decision?

The engine manufacturer decides which end is the front as shown in post #2.

OK, ... so cylinder #1 (decided upon by the mfr) is always at the "front" of the engine?

As I stated before, on a Kubota diesel engine, the number one cylinder is always at the front of the engine and the flywheel is always at the rear. This arrangement is decided and assigned by Kubota.
