Mechanical System Specifications
The manual delivers structured data essential for full-system overhauls. It outlines the documentation for engine removal, cylinder head torquing sequences, valve train specs, and timing gear configurations for the C-123 and C-135 powerplants. For chassis work, you will find steering gear teardown specs for both adjustable and non-adjustable front axles. The drivetrain section lays out clearances for major transmission overhauls, covering countershafts, spline shafts, and dual-range units to help you nail the correct backlash and shim selection. Brake service parameters are also detailed for both external band and self-energizing disc setups.
Hydraulic and Electrical Data
Troubleshooting fluid power issues is straightforward with the included breakdown of Touch-Control and Hydra-Touch systems. The text documents circuit pressure testing, pump rebuild specs, and valve block diagnostics. On the electrical side, it covers timing parameters for battery ignition and magneto systems. You get specific advance curves and breaker point gaps mapped to their corresponding distributor symbols. Key metrics like the 0.014-inch intake valve clearance and the 3.5-gallon coolant capacity are listed in quick-reference tables. It also includes exact magneto pick-up resistance values for the 100/200 series, ensuring your ignition rebuilds meet factory standards.
