on the swivel housing u should find two plugs, one on top, and one below. remove the top plug, clean around, etc, remove bottom plug and alow any oil to flow out, leave for 15mins if u want. once u've done this then take your packet of greese and squeeze it in thru top plug hole. dont worry if greese doesnt appear at bottom plug. as long as u have got the whole packet in there then its fine. heat with use will thinen grease and throw it in nocks and cranies. once satisfied then replace plugs, make sure all areas around plugs are clean as possible before refitting etc. if u've had problems with oil leaks on swivel as i did then new seals may be advised, but the one shot is much better than the oil they were built with. get urself a haynes manual. sound investment, i always got mine with me.
hope this helps
