Abstract

An apparatus for and method of installing a drive chain ( 201 ) uses one or more restraints ( 101 ) that do not interfere with drive chain function in an operating engine nor fall off during installation. One or more restraints ( 101 ) near a sprocket ( 207 ) attached to the crankshaft or other device facilitate installation of one or more drive chains ( 201 ) during engine assembly by limiting the movement of the drive chain ( 201 ) away from the sprocket ( 207 ).

Claims (15)

1. A drive chain assembly restraint, comprising at least one restraint mounted to a first engine component, wherein the at least one restraints disposed near an outer perimeter of at least one sprocket attached to a second engine component, wherein the at least one restraint is capable of engaging a drive chain between the at least one sprocket and the restraint to prevent the drive chain from dislodging from the at least one sprocket while allowing the drive chain to move freely during engine operation, and wherein a distance between the outer perimeter of the at least one sprocket and the restraint limits movement of the drive chain relative to the sprocket such that the drive chain is engaged with the sprocket, and

wherein the drive chain moves past the at least one restraint without contact when the engine is operating.

2. A drive chain assembly restraint, comprising at least one restraint mounted to a first engine component, wherein the at least one restraint is disposed near an outer perimeter of at least one sprocket attached to a second engine component, wherein the at least one restraint is capable of engaging a drive chain between the at least one sprocket and the restraint to prevent the drive chain from dislodging from the at least one sprocket while allowing the drive chain to move freely during engine operation, and wherein a distance between the outer perimeter of the at least one sprocket and the restraint limits movement of the drive chain relative to the sprocket such that the drive chain is engaged with the sprocket, and

wherein at least one restraint attaches to an oil pump of the engine.

3. The drive chain assembly restraint of claim 2 , wherein at least one restraint attaches to a backplate of the oil pump.

4. A drive chain assembly restraint, comprising:

a sprocket attached to a crankshaft that is mounted in an engine;

a drive chain engaged with the sprocket; and

an engine component having at least one restraint such that, when the engine component is mounted on the engine, the restraint is disposed near an outer perimeter of the sprocket limits movement of the drive chain such that the drive chain remains engaged with the sprocket during movement of the engine, wherein the sprocket comprises a plurality of teeth along the outer perimeter of the sprocket, and wherein a distance between the teeth and the restraint limits movement of the drive chain relative to the sprocket such that the drive chain is engaged with the sprocket, and

wherein at least one restraint is attached to an oil pump having a backplate.

5. A drive chain assembly restraint, comprising:

a sprocket attached to a crankshaft that is mounted in an engine;

a drive chain engagoed with the sprocket; and

an engine component having at least on restraint such that, when the engine component is mounted on the engine, the restraint is disposed near an outer perimeter of the sprocket limits movement of the drive ive chain such that drive chyain remains engaged with the sprocket duringt movement of the engine, wherein the sprocket comprises a plurality of teeth along the outer perimeter of the sprocket, and wherein a distance between the teeth and the restraint limits movement of the drive chain relative to the sprocket such that the drive chain is engaged with the sprocket, and

wherein the at least one restraint has no moving parts and passively engages the drive chain.
