09換快齒

各位C兄09換快齒時候有冇特別方法可以容易D將
個原裝齒拎返出黎,
因為........真係好實呀

before u install the gear, u must apply some bearing oil onto the thread...otherwise, u will found difficulty to remove the gear later.....

now, u can try to apply some bearing oil or after run oil into the gap between gear and the gear holder...if still cant remove, try to use heat
