final drive (rear hub)

Beitrag von IIIrd » Mittwoch 8. Oktober 2008, 14:23

Hello All,
i have a bit of an oil leak from the rear hub. its coming from the protruding plug at the top of the hub. sorry i can't name the part as the workshop manual doesnt name it. is it just a matter of pulling the plug out and replacing an o ring...or it is more serious.
the leak came on all of a sudden this morning. i've given it a light tap with a hammer in case its become useated due to vibration....
the bike is a 2002 model with an 05 plate, millage is 5000,
cheers for any help
sean

Hi,
is it the deairation on the top of the axle gearing :?: :?: :?:
Maybe there is too much foam on the gear oil.
Change the oil, then it should be better :wink:

Regards
Jürgen

Hi there,

it´s exactly as Maddog says : change the oil for a better quality one (Castrol Gear-Oil SAE 80 Hypoid "GL4" , "GL5", or "GL6" works fine...you could use Yamaha´s own Gear-Oil, but it is way too expensive))

Do not try to remove the venting-plug and do not tap it with a hammer..!!

The reason for the leakage is low quality gear oil filled in at the factory :evil: In combination with humid weather and/or high speeds it tends to foam and then spills from the venting plug..

Should the oil already be "milky" - ride the bike before changing the oil..it should be warm - drain completely and rinse with a bit of fresh oil and drain that too. After that, fill up to the beginning of the threads of the filler *..

greets
