This document provides instructions for removing the engine from STX Steiger tractors. It is the first book in a 12-book service manual. The removal process involves 21 steps, including draining fluids, disconnecting wiring harnesses, removing hoses and tubes, and detaching mounting hardware. The radiator, air cleaner, exhaust system, air conditioning components, fuel lines, and wiring must all be disconnected before an overhead hoist can be used to lift the engine out of the tractor.
