PURPOSE:To facilitate replacement of lubricant by forming an oil inspection hole through an oil pan of vessel engine such that an oil discharge rod such as engine turning rod usable for other purposes can be inserted thereby also using as an oil discharge hole. CONSTITUTION:When confirming lubricant, an oil inspection rod coupling 6 is fixed to an oil pan 3 then an oil inspection rod 2 is inserted to confirm oil amount and dirtiness in oil pan. While when replacing lubricant, said coupling 6 is removed from oil pan 3 to insert oil discharge rod 7 into oil pan 3 then an oil discharge pipe 5 is coupled to the other end to replace lubricant while sucking manually or through motor pump. In place of oil discharge rod 7, oil discharge pipe 5 can be inserted directly into oil pan but metal pipe will facilitate replacement of lubricant more. Consequently metal oil discharge rod 7 is employed and used also as a turning rod for engine. |
