Abstract
A device for facilitating the separation and removal of an engine cover from a sealing surface on an engine. The engine cover puller may reduce or eliminate the deformation of an engine cover during its removal and allows for its potential reuse. In addition, the engine cover puller may reduce or eliminate the damage to the sealing surfaces between the engine cover and the engine that may occur during an engine cover removal.
Claims13
A method for separating an engine cover from a sealing surface with the remainder of an engine, said method comprising the steps of:
- positioning a base to contact at least a first portion of said engine cover;
- positioning a puller arm to engage at least a second portion of said engine cover;
- moving a lever arm pivotably attached to said base and to said puller arm;
- and
- generating a separating force by said movement of said lever arm sufficient to remove said engine cover from at least a portion of said sealing surface on said remainder of an engine,
- wherein said lever arm pivots about a first axis relative to said base;
- wherein said puller arm pivots about a second axis relative to said lever arm;
- and
- wherein said first axis is spaced from said second axis.
An engine cover puller apparatus, said apparatus comprising:
- a base to contact at least a first portion of an engine cover;
- a lever arm having a first end and a second end, said first end of said lever arm pivotably connected to said base;
- a puller arm adapted to engage said engine cover, said puller arm pivotably connected to said lever arm between said first end and said second end of said lever arm;
- and
- at least one channel on said puller arm, said at least one channel providing a complementary fit to engage at least a second portion of said engine cover;
- wherein when an upward separation force is applied to said second end of said lever arm while said puller arm engages said second portion of said engine cover, said engine cover separates from said sealing surface of said engine.
A device for separating a part of an engine from a sealing surface with the remainder of said engine, said device comprising:
- a base to contact at least a first portion of said part of an engine;
- a lever arm having a first end and a second end, said first end of said lever arm pivotably connected to said base;
- a puller arm adapted to engage said part of an engine, said puller arm pivotably connected to said lever arm between said first and said second ends of said lever arm;
- and
- at least one channel on said puller arm, said at least one channel providing a complementary fit to engage at least a second portion of said part of an engine;
- wherein when an upward separation force is applied to said second end of said lever arm while said puller arm engages said second portion of said part of an engine, said part of en engine separates from said sealing surface with said remainder of an engine.
A device for separating a part of an engine from a sealing surface with the remainder of said engine, said device comprising;
- a base to contact at least a first portion of said part of an engine at an upper surface;
- a lever arm pivotably mounted to said base to pivot about a first axis;
- a puller arm adapted to engage a second portion of said part of an engine along an underside thereof and to apply a pulling force thereto, said puller arm pivotably mounted to said lever arm for pivoting about a second axis spaced from said first axis;
- and
- at least one channel on said puller arm, said at least one channel providing a complementary fit to engage said part of an engine at a lower surface of a second portion;
- whereby pivoting of said lever arm about said first axis by applying an upward separating force to said second end of said lever arm lifts said puller arm upward with respect to said lower surface of said second portion of said part of an engine and applies a pulling force thereto, thereby separating said part of an engine from said sealing surface with the remainder of said engine.
