<p>PURPOSE: A jig for fastening a cylinder cover hydraulic nut is provided to reduce working time by carrying out processes without interference with peripheral components when coupling hydraulic nuts. CONSTITUTION: A jig for fastening a cylinder cover hydraulic nut comprises a ring-shaped body(110), a fixing bolt(120), and a lever(130). The ring-shaped body surrounds the outer circumference of a hydraulic nut with maintaining constant intervals with the outer circumference of the hydraulic nut(20) coupled on a bolt(11) projected to the upper part of a cylinder cover to fix the cylinder cover(10) installed at a ship engine. A plurality of fixing bolts are arranged along the circumference of the ring-shaped body and is coupled on a coupling hole formed on the outer circumference of the hydraulic nut and fixes the ring-shaped body on the hydraulic nut. The lever is extended upward from the ring-shaped body.</p> |
