Oil seal behind gear lever-kick start TS150?

[John Ridgley]

Good Afternoon, my TS150 has developed a gear box oil leak from behind the kick start/gear lever, intially just a dampness, now quite a lot of oil seems to be running and dripping after a good run out- it seems worse since i changed the gear box oil. The bike had been standing a good 6 months before i acquired it. Is there a seal behind the shaft and is it easy to replace or is there something else? Many thanks in advance!

There is an o-ring. Are you sure that you haven’t overfilled it?

Hi Rob, Thank you. Thats what i thought. The gear box oil was low and dirty when i changed it and although i measured out the recommended oil volume in the Haynes manual it didnt seem to run out of the level check hole, even when i added a little bit more. I resisted the temptation to put more in and rode it instead- the gear change was much smoother and clutch less (bit still a bit) dragging when cold but after a good run, oil was visibly seeping out from behind the shaft though once the bike had cooled, the seepage seemed to stop. I am tempted to just keep using for now and top up as required and deal with it when it comes off the rode this winter. Any other thoughts gratefully received!

Have you drained old oil from clutch compartment or only through main sump plug?

[John Ridgley]

Thanks again Rob, is there a separate drain plug for the clutch compartment?

[Rob Holusza]

Yes, m8 bolt right below clutch basket.
