RX3 Lubrication System: Checking the Engine Oil Level

[SpudRider]

Indeed, thanks for sharing the excellent photographs. If you have more photos, please do post them.

I'm not surprised by the quality of manufacture. The engine in my Zongshen ZS200GY-2 is built to similarly high standards.

Looking at the photos, It appears the NC177MM engine has two oil pumps. It seems an oil pump is located on both the left, and right halves of the crankcase. Is this correct? If so, what mechanism drives the oil pump under the stator cover on the left side of the engine?

[SpudRider]

Looking at the photograph below, it is obvious the oil pump on the right half of the crankcase is driven by two plastic gears which mesh with the gear on the rear of the clutch basket.



Does the oil pump shaft, part #9, inside a right oil pump, transmit power to another oil pump on the left crankcase cover?

Np ,

Crossfire and my bike same, nice shoot spudrider.

Yes 1 shaft, double pump unite , (or i think that )

Left side is just closed a plate , bottom of alternator/stator/volant.

power source is clutch basket , bottom second gear, and double plastic gear (or i think that )

[Co2]

No : 9 shaft , 3x pin, 3x pin bed 1x left 1x right , 1x powersorce of plastic gear.

Great photos Co2,

Has got me thinking about the possibility of fitting a kick start

Photo is my electric+kickstarter version model zs177mm 5.gears, same to crossfire xz250rr dirt/sm version , but offcourse why not, just need dimensions...of Rx3 case. , im buy Rx3 gear system all, and parts 100% compatible

Thank you for confirming my assessment, and thanks for posting more of the excellent engine photographs. Please do post more photos, we are learning a lot from them.

Yes, you certainly can install a kick starter. You merely need to obtain the kick starter parts, and a new right crankcase cover. The parts will easily install. The only question is whether the RX3 frame, engine placement, foot peg position, et cetera, will allow enough space for someone to operate the kick starter.

There must be a very large bearing supporting the counter shaft as it exits the left half of the crankcase. The hole is located at the bottom left of the following photograph, which is inverted.

CO2,

If you have time, please post a photograph of the inside of the stator cover. The crankcase vent exits the front of the stator cover, near the engine counter balancer, and we are interested in examining this area.

Ofcourse , just in 10 min.

Crank and other all ZS177MM / NC250 Beraings

6207 LU ( 1 side sealant.) x1

6207 c3px1 (naked non seal) x1

6304 x1

63 / 22 (or 6322 idk writed on bearing that code.) x1

6203 / p63 x2

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...

Thank you.

I'm sure one side of the bearing is sealed to retain oil and/or prevent oil from passing through to an unwanted area. This is not unusual.

Balancer and crank




statör cup











BLUE NYLON , MARKED HOLE'S , İ HOPE HELP U BOSS.

Balance and ststor side.



Balancer side in, bottom of cylinder/piston side, a same to carburator JET , i ask that part my moto master friend sad, sprayed bottom for piston oil idk ,

CO2,

While you have the engine apart, I suggest you examine the large spring in the gear shifter. I have read one report of it failing.
