Speedo gearbox drive (Front wheel)

[Lobo]

Hi,

Doing a major overhaul of the hubs as I put on new rims....

Anyways, whilst the gear drive looks like its never meant to be serviced / dismantled... any pointers as to whether it can easily be so... and tips? 

Or do I just put in fresh grease & give it an external clean?

Ta,
S

Ah! Thanks OddJob... whilst I spotted a pawl type thing on the outside (immovable) I didn't think to clean away the internal grease and go looking inside.

Will have a look tomorrow,
Cheers,
S
