| Post subject: | oil leak - drive sprocket |
I decided to chase down a few leaks today, the drive sprocket shaft being one of them. Oil appears to be leaking out from the center of the spacer.  Is there supposed to be an o ring behind it or something? The transmission seals are new. Oil seems to be leaking from between the drive shaft and the "collar" or metal spacer. This is on a H2a |

There is a o ring on the other end of the collar that gets destroyed when you tighten down the sprocket. That's probably it. |

towards the transmission, right? can't see how it would work towards the sprocket. It never had one when I disassembled it. |

The placement of the O-ring has been discussed before and its placement is not shown correctly in a lot of manuals and parts books. Look here: http://www.3cyl.com/mraxl/manuals/maint ... .htm#trans and pay close attention to the note in red. |

Note: The O-Ring shown behind the engine sprocket should be located between the spacer and ball bearing. Wow, thanks Dale, Manuals are all wrong! Wholly buckets. |

A trap for young players, that one, and another reason tips like that make this site so valuable - and the resource site, of course! |

The steel spacer collar should also have one end of it with a larger chamfer than the other. The larger chamfer goes in, it holds the O ring in position. The O ring actually takes the shape of the chamfer, and the bearing relief in the inner race to shaft interface as it is pancaked into place. |
