Bearing, Bottle Jack, Electric Motor, TrekerAbstract
This research modifies the bottle jack to remove the electric motor bearing of a water pump with a jack
capacity of 2 tons. Bottle jacks are generally used to lift vehicles such as cars. The bottle jack can be modified so
that it can be used as a bearing removal device. In general, the way to remove the bearing is still manual, namely
by hitting it. The purpose of making this tool is to make it easier to remove the water pump electric motor bearing.
The working principle of this removal tool is to use hydraulic power as the driving force. Pushers from the bottom
up on the water pump dynamo shaft and a tracker as a means of holding the bearing. The bearing holder is needed
so that the bearing can be separated from the water pump dynamo shaft. The specifications of the tool are that it
has a height of 16 - 27 cm. The width of the tool is 6 cm and the maximum pressure capacity of the bottle jack is
2 tons. The trial results of the bottle jack modification tool to remove the water pump electric motor bearings
obtained an average time of 45 seconds.
