Abstract

Human needs are increasing in the world of transportation, especially for two-wheeled vehicles or more. In the automotive world, especially cars, there are various kinds of systems that work. These systems work in conjunction with one another so that if one of these systems is damaged, the car will be damaged. such as damage to the cooling system which can cause overheating of the engine. Overheating is the occurrence of excessive heat above the engine's working temperature which is caused by damage to one of the components of the cooling system. The occurrence of overheating in the Hilux double cabin car engine is caused by a lack of coolant, the thermostat is not functioning properly, the radiator cap is leaking, the inlet and outlet hoses are cracked and the water pump is damaged. To avoid damage, preventive maintenance must be carried out. Check the coolant in the radiator reservoir every 1 week and change the fluid every 80,000 km. Thermostat replacement every 80,000 km. Replacement of radiator caps every 80,000 km. Replacement of inlet and outlet hoses every 80,000 km. Water pump replacement every 80,000 km. and a v-belt replacement every 60,000 km.

Abstract

This research modifies the bottle jack to remove the electric motor bearing of a water pump with a jackcapacity of 2 tons. Bottle jacks are generally used to lift vehicles such as cars. The bottle jack can be modified sothat it can be used as a bearing removal device. In general, the way to remove the bearing is still manual, namelyby 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 bottomup on the water pump dynamo shaft and a tracker as a means of holding the bearing. The bearing holder is neededso that the bearing can be separated from the water pump dynamo shaft. The specifications of the tool are that ithas a height of 16 - 27 cm. The width of the tool is 6 cm and the maximum pressure capacity of the bottle jack is2 tons. The trial results of the bottle jack modification tool to remove the water pump electric motor bearingsobtained an average time of 45 seconds.
