section swept Posted December 14, 2019 Share Posted December 14, 2019 Check gearbox oil quantity as well. Check gearbox breather is clear. 1 Quote Link to comment Share on other sites More sharing options...

Drips only came to light after draining and re-filling, so poss overfilled slightly, although pretty sure not done so. Good point re the breather, though.

Twinshockandy Posted March 7, 2020 Author Share Posted March 7, 2020 Ok furher to above topic, just replaced gear shaft oil seal due to oil passing it, checked and refilled oil to correct capacity and checked what I think is gearbox breather tube, which is clear............upon starting and allowing tick over, find I'm now getting oil running out from behind gearbox sprocket (gear shaft seal is oil tight) Any idea's,.........? Many thanks Andy Quote Link to comment Share on other sites More sharing options...
thai-ty Posted May 11, 2020 Share Posted May 11, 2020 Mainshaft (output shaft) oil seal is shot also. The shaft your sprkt sits on. Sounds like a lot of dried out/aged/incorrectly fitted/poor quality aftermarket seals on the motor..... 1 Quote Link to comment Share on other sites More sharing options...
