section swept Posted February 10, 2019 Report Share Posted February 10, 2019 Yes fairly certain Mr Yamaha wouldn’t make it that difficult. No need to split the cases, this is a seal that has to take punishment so just like the other TY models its a gentle lever out or use various methods like self tappers and grips but usually just a simple appropriate sized lever will flick it out. Lay the bike over so aa to keep the oil in the box if you are not draining out. Plenty of grease around the new seal lip and I believe that the sleeve that the seal rubs against comes out too so give it a good clean and grease.??

bondy Posted February 10, 2019 Author Report Share Posted February 10, 2019 Nice 1 I wasn't sure I normally do bultaco and there the same the seal just pops out I normally use a blunt rounded leaver to tap 1 side and the other pops out I then flick it out with a small flat driver cheers for the replay Quote Link to comment Share on other sites More sharing options...
