Applying precise torque to fasteners, critical in engine assembly. Types: Torque screwdrivers, beam torque wrenches. Pullers and Extractors Use: Removing gears, bearings, or pulleys from shafts. Types: Bearing pullers, gear pullers. Hydraulic Jacks Use: Lifting heavy loads such as veh
ines (ICE), which utilized gasoline or diesel fuels. Karl Benz's creation of the first gasoline-powered car in 1885 marked a significant milestone. These engines offered greater efficiency, mobility, and practicality, leading
ronmental conditions. Operational Demands: Continuous versus intermittent operation, dry or wet running. Maintenance Capabilities: Ease of seal replacement and access. Cost-Effectiveness: Balancing initial investment
