MC-54 Gear Oil Bolts

[hoganron]

Does anyone have a photo that clearly shows where the gear oil fill and drain bolts are on the Roketa MC-54?

I would certainly appreciate it. The manual is definitely un-clear.

I just did my friends new MC-54-250B. The drain is at the very bottom of the gear box. It is easily identifiable as it is larger than the other bolts an it has a crushable cooper gasket. The fill is a plastic thumb plug on the top rear of the gear box. The only problem is that there is no dip stick. We simply measured what came out and replaced it with same amount of synthetic 80-90 wt. (about 78 of a cup or 200 ml.) If you still need pix , PM me and I'll run over and take a pix. By the way we had a considerable amount of wear particles come out with oil,
Sure glad we changed it!

Happy scoot'n

Thanks,

However, the only bolt that is obvious, is the main oil drain plug near the oil dipstick.

I am starting to wonder if I need to remove the CVT cover???

There is definitely nothing directly under the gear box to drain the gear fluid.

I have been searching for weeks with no luck at all. I just may need to take it to a shop instead. I just did not want to get charged for something that I could simply do.

Hoganron;
If you have the CFMoto/Honda engine, the CVT cover must come off to locate the drain bolt. If you have the Linhai/Yamaha engine with the dipstick-like screw-on filler cap, the drain bolt is outside of the CVT cover, under the bottom rear portion of the CVT. On my Linhai engine, there is a black vent hose that attaches to the housing just below the drain bolt.

In that case, it may be the CFMoto/Honda Engine. The only viewable dipstick is the large one on the right for the main oil.

Would you by chance have a photo of this area to confirm?

Thanks!

Is yours a MC-54-250 or MC-54-250B? the B is the Yamaha clone

[hoganron]

It is a MC-54-250B.

Do you have information on this one in regards to the gear oil bolts?

Thanks

[hoganron]

Scratch that, it is a MC-54-250. I say this because that is the labling on the side panels of the scooter.

I guess that is accurate?

Forget the labels since they can say anything. Look at the engine cylinder and see if it runs vertical or horizontal. Vertical is the CFMoto engine (Honda) and there is a link to the Honda Helix CN250 manual on my site. Here is a link to the CVT Oil change on the CFMoto www.oregonvintage.com/250cvt.pdf

If the cylinder runs horizontal, it's the Linhai (Yamaha) clone. In that case, look through the article on the RoadRunner Racer on my site and if I recall correctly, the Linhai gear box oil change is covered there for you. Stan

Download the Honda Helix manual (bill.laudeman.com/helix/manual/index.html) and you will find a wealth of information in it. Just save the file or print it out and you'll be covered. Stan

I have a new RoadRunner 250cc scooter, My husband changed the coolant already, it only has 26 miles on it, other than general assembly, is there anything else he should do to it? When should he change the gear oil?

kimberlytracy03,

Most of us believe it is a good idea to change all the fluids right away to make sure you have the best possible oil and coolant in the system during the important break-in period. Most companies recommend at 600km and then every 1000km after that.
