Maintenance on Jonway Chinese 50cc scooter

Thanks for the advice Robert. I successfully drained the engine oil and replaced it. I think I located the gear oil drain bolt (smaller bolt under the transmission). However, I see no filler bolt anywhere on top of the transmission. I assume that the transmission is the black case located on the left side of the scooter directly under the air filter. If that's the transmission, then there is no filler bolt on top. Any more advice?  (Oct 14, 2008 | post #5)

Regarding Robert's post, that drain bolt described sure looks like the engine oil drain bolt to me. There is only one drain bolt on the underside of the transmission and I'm assuming it contains the engine oil. So any other ideas on where to drain the gear oil and fill the gear oil?  (Oct 10, 2008 | post #3)

Maintenance on Jonway Chinese 50cc scooter

Does anyone know how to replace the gear oil on a Jonway Chinese-made 50cc scooter? I know how to replace the engine oil, but the owners manual also suggests replacing the gear oil after the first 300 km. It says "take off the gear oil filling bolt, fill in high quality gear oil, then fasten gear oil filling bolt". There are no illustrations in the manual and I can only find the engine oil drain bolt.  (Oct 4, 2008 | post #1)
