DESC:TECHNICAL FIELD
[001] The embodiments herein relate to an apparatus and a method for locking (holding) an engine coolant pump pulley (water pump pulley) and an engine damper pulley (crankshaft pulley) in a stationary position (fixed position) during assembling of an engine coolant fan assembly (engine viscus fan assembly) to the engine coolant pump pulley.

BACKGROUND
[002] Engine coolant fan assembly is used for cooling an engine of the vehicle. During the engine assembly process, engine viscus fan has to be assembled on a water pump pulley. During tightening (fastening) engine viscus fan, the water pump has to be held by a spanner type hand held holding tool as both rotate in clockwise direction and the viscus fan has to be tightened in anticlockwise direction. Further, cooling fan is assembled and torqued on MDI engines and spanner type hand held locking tool is used to lock the fan and torque it in assembly line. The aforementioned tool may be unsafe for an operator (person assembling the engine) as it may slip during torqueing and may injure the operator.
[003] Therefore, there exists a need for an apparatus and a method for locking (holding) an engine coolant pump pulley (water pump pulley) and an engine damper pulley (crankshaft pulley) in a stationary position (fixed position/ immovable position) during assembling (fastening/ tightening) of an engine coolant fan assembly (engine viscus fan assembly/ fan clutch assembly) to the engine coolant pump pulley. Further, there exists a need for an apparatus, which could be adjusted to at least one of a plurality of positions (adjustable length) in accordance to the distance between an engine coolant pump pulley (water pump pulley) and an engine damper pulley (crankshaft pulley) respective to corresponding engine size and configuration to enable the apparatus (locking tool) to lock (hold) the engine coolant pump pulley (water pump pulley) and the engine damper pulley (crankshaft pulley) in a stationary position (fixed position/ immovable position) to restrict the rotational movement of the engine coolant pump pulley during assembling (fastening/ tightening) of an engine coolant fan assembly (engine viscus fan assembly/ fan clutch assembly) to the engine coolant pump pulley. Furthermore, there exists a need for an apparatus, which obviates the aforementioned drawbacks.
