Complete Manual Information
Yamaha CS340, CS340E Ovation Service Manual - 1989-1990
Engineered for precision maintenance, this factory-authorized service manual provides the foundational engineering data required for the 81E-series chassis. Proper application of the specified Esso-Beacon 325 grease or Aero Shell Grease #7 on critical bearing surfaces ensures low-temperature component mobility and prevents premature catastrophic failure in extreme sub-zero environments. Technical professionals utilize these specific lubricant standards to maintain factory-grade reliability and operational uptime.

Technical Depth & Factory Benchmarks
Engine performance is regulated through rigorous calibration standards, including a specified idle speed of 1,600 r/min. Precision measurement data covers every internal component, such as the cylinder bore diameter of 60.00 mm and a piston-to-cylinder clearance range of 0.045–0.050 mm. These benchmarks allow technicians to verify wear limits and ensure the 337cc engine operates within its designed thermodynamic envelope.
Visual Navigation & Schematic Architecture
Illustrated symbols and thumb tabs categorize the documentation into nine distinct functional zones, ranging from engine architecture to electrical distribution. Exploded view diagrams utilize a standardized legend to identify specific lubrication points, requiring either engine oil, gear oil, or molybdenum disulfide grease depending on the mechanical load and friction requirements of the assembly.
