RX3 Lubrication System: Checking the Engine Oil Level

[SpudRider]

The gearbox contains the main oil reservoir, and the oil sight glass. The gearbox is drained by the magnetic drain plug located underneath the engine.

Oil is scavanged from the bottom of the gearbox by the right oil pump, after the oil is sucked through the oil screen located behind the oil filter.



The right oil pump then sends oil to the oil filter. Another oil journal lubricates the right side of the transmission. I strongly suspect an additional oil journal connects from the right crankcase to the right crankcase cover. This oil journal should feed oil through the crankshaft to lubricate the lower end of the connecting rod, et cetera.





CO2,

If you have time, please post several photographs of the inside of the right crankcase cover. Once again, thanks for posting all the great photos.

The oil filter contains a pressure valve. If the oil filter is clogged, excess oil pressure will open the valve, and allow oil to bypass the oil filter.

The right oil pump also appears to contain a pressure release valve.

6004 x2

61805 x2

61902 x2

total 12 bearing , İ changed all new , before i research all bearings NSK/FAG/SKF japan qualited but my little village/town..... , and founded original xmotos parts again my s.. distrubutor....


Crank bearings is just 1 piece 1 side is selant , and other total all naked bearings, but why jus 1 bearing have sealant , other same size 6207 is naked?? that is engineering think/trick or cheap type idk any idea?

photos comin 10-min...

Thanks for posting all the bearing information, CO2.

CO2,

Must you remove the flywheel before you can replace the stator? Where does the stator attach to the engine?

Stator position.



Right crankcase



Right crankcase



Steel oil filter (best, i think better than paper filter. 2 years than, 16.000 kilometer same filter.)



Sttel filter in, spring valf.



Oil pump , valf



Oiljet



Oiljet Cylinder contact channel (small)

Thanks for posting all the great photos. Can you please post a photograph of the inside of the right crankcase cover?

[SpudRider]

I'm very pleased to know the stator mounts inside the stator cover. I did not see the mounting holes in the previous photo.

Thank you. I see the oil journal which feeds oil to the end of the crankshaft.

[SpudRider]

I agree; I think the reusable, steel oil filters are best. I own three of them.

[SpudRider]

As small as it appears, that hole must be the oil journal which lubricates the cylinder head. You are very helpful, and we appreciate your excellent photos.

Blow the balancer? No one here is judging you.
Not knowing the orientation of the passages in the balance weight in relation to the crank pin, I guess the breathing is timed, just like in the old Indian and H-D motors. Also, the holes spinning will expel liquid while letting vapors pass. VERY well thought out system. Wow!

Really enjoying what you are sharing, Co2!

Your welcome Jay / SpudRider , together solving problems/troubleshooting wonder/assistance/share , forum power , tried , i need cold beer now

If I were in Turkey, I would buy you that cold beer.
