Teledyne Continental TSIO-520 Sandcast Series Overhaul Manual

This is the complete overhaul manual for the Teledyne Continental Motors TSIO-520 Sandcast Series aircraft engine, published February 1989 and prepared in the GAMA (General Aviation Manufacturers Association) format. It covers ten engine models in the series: TSIO-520-C, TSIO-520-G, TSIO-520-H, TSIO-520-M, TSIO-520-P, TSIO-520-R, TSIO-520-T, L/TSIO-520-AE, TSIO-520-AF and TSIO-520-CE. Every chapter is written for the overhaul facility and the certificated mechanic performing a major overhaul, top overhaul, inspection or repair on these turbocharged, fuel-injected, horizontally opposed six-cylinder engines.

• 72 – Engine Reciprocating: general description of crankcase, crankshaft, connecting rods, camshaft, pistons, lifters, cylinders, gear train, lubrication system, valve mechanism, induction system, exhaust system and ignition system; disassembly; cleaning, repair and replacement; inspection; assembly of sub-assemblies; final assembly; testing after overhaul; engine preservation
• 73 – Engine Fuel System: set-up procedure, turbocharged engines, fuel pressure regulators, special set-up procedures, fuel system pressure and flow value charts, fuel system troubleshooting chart
• 74 – Ignition: TCM ignition system, magneto installation, harness assembly installation, ignition troubleshooting, Slick ignition system

• 76 – Engine Controls: cruise control by performance curve, cruise control by E.G.T., performance charts for every model
• 77 – Engine Indicating: operating limits, engine troubleshooting chart
• 78 – Exhaust: exhaust system for the TSIO-520-T, exhaust system troubleshooting chart
• 79 – Oil: approved oil products, oil system troubleshooting chart
• 80 – Starting: prestarting, starting, ground warm-up, pre-takeoff check, flooded engine, cold weather operation, preheating, hot weather operation, ground operation at high altitude airports
• 81 – Turbines: turbocharger, wastegates (fixed orifice and hydraulic), controllers (absolute pressure, rate of change, ratio, variable absolute pressure), turbocharger lubrication system, turbocharging system troubleshooting

What this gives a technician is not just a list of chapters but a working rebuild sequence. The disassembly chapter walks through the ignition system, fuel injection system (with separate procedures for the C, G, H, M, P, R and AF group, the AE and the CE), magneto and accessory drives, induction system, oil sump, oil cooler, alternator, starter and starter drive adapter, oil pump, cylinder and piston assemblies, crankcase, camshaft, crankshaft and exhaust system. The cleaning, repair and replacement chapter then covers how each of those parts is degreased, inspected for damage and either reworked or replaced, including stud replacement, helical coil insert installation, valve guide removal and installation, hydraulic valve lifter service, connecting rod service, crankshaft assembly and ignition cable replacement. The inspection chapter adds visual, magnetic particle, ultrasonic and fluorescent particle inspection procedures plus an extensive table of limits. Assembly is then split into sub-assembly build-up, final assembly and the crankcase torquing sequence, and the testing chapter finishes with the standard acceptance test, oil consumption determination and test operating limits.

Technical Depth for the TSIO-520 Series

The specification chapter alone is worth the download for anyone maintaining a TSIO-520. It documents the six-cylinder, air-cooled, horizontally opposed layout with 520 cubic inches displacement, 5.25 inch bore and 4.00 inch stroke, 7.5:1 compression ratio and firing order 1-6-3-2-5-4. Basic dry engine weights are listed per model, along with rated maximum continuous BHP and recommended maximum cruise BHP. Crankshaft speeds, intake manifold pressures, unmetered fuel pressure ranges, oil specification MHS-24 / MHS-25, oil sump capacities, oil pressure and oil temperature limits, ignition timing in degrees before top centre for both magnetos of each model, approved magnetos and approved spark plugs are all given. Recommended overhaul periods are listed model by model, ranging from 1400 hours to 2000 hours, with the option of a TBO increase to 1600 hours for certain M, P and R specifications after the parts changes listed in the manual are completed.

The chapter on standard practices documents the differential pressure cylinder leakage test in full, including the master orifice tool calibration, the static seal check, the dynamic seal check and a troubleshooting table of discrepancies and corrective actions. The crankcase threading procedure shows the Permatex and silk thread layout used when joining the crankcase halves, and the lockwire procedure diagrams the typical safety wire patterns. The table of limits covers gear backlash, cylinder and head assembly, rocker arms and shafts, pistons, rings and pins, crankcase and attached parts, spring test data, crankshaft, camshaft, accessory drive idler arm, oil pressure pump assembly, oil pressure relief valve assembly, tachometer drive assembly and starter drive, so a mechanic can judge wear against both new part limits and serviceable limits.

Diagrams and Illustrations

The manual is heavily illustrated. Exploded views cover the ignition system, fuel injection system, magneto and accessory drives, induction system, oil sump, oil cooler, starter and starter drive adapter, oil pump, cylinder and piston assembly, crankcase, camshaft assembly, crankshaft group and exhaust assembly. Wiring diagrams are provided for the ignition harness, and schematic diagrams cover the lubrication system, the fuel system and the basic turbocharger system. Setting height diagrams, dimension drawings for cylinder assemblies, valve rocker bushing dimensions, connecting rod and bushing dimensions, fuel manifold valve fitting locations, fuel pump fitting locations and air throttle fitting locations are all included so components can be reassembled and adjusted correctly.

What You Can Do With This Overhaul Manual

• Perform a full major overhaul of any TSIO-520 Sandcast Series engine using the correct disassembly, cleaning, inspection, repair, assembly and torque sequences
• Set up and adjust the fuel injection system, including unmetered and metered fuel pressures at idle and full throttle for each model
• Time the magnetos to the engine and to each other, and check magneto spread within limits
• Carry out a differential pressure cylinder leakage check and interpret it against the master orifice calibrated reading
• Inspect and repair crankcase studs, helical coil inserts, valve guides, valve seats, rocker arms, connecting rods, pistons, rings and hydraulic valve lifters
• Assemble the crankcase, camshaft, crankshaft, connecting rods, cylinders and pistons, and torque them in the correct sequence
• Run the overhauled engine through the standard acceptance test and oil consumption determination
• Preserve an engine for flyable, temporary or indefinite storage and return it to service
• Troubleshoot fuel, ignition, exhaust, oil and turbocharging system faults against the manufacturer’s own fault tables

Why Correct Procedures and Specifications Matter on a TSIO-520

These are turbocharged, fuel-injected engines operating behind a constant speed propeller, and the tolerances that hold them together are tight. Torquing the crankcase in the wrong sequence, fitting the wrong oversize stud, setting magneto timing a couple of degrees out or running the fuel injection system at the wrong metered pressure will all shorten engine life and can lead to detonation, pre-ignition or structural failure. This manual gives the overhauler the figures and the order of operations in the same form Teledyne Continental Motors published them: setting heights, table of limits, torquing sequences, spring test data, gear backlash, valve and piston ring clearances, and the acceptance test limits the finished engine must meet. Everything you need to compare a worn part against a serviceable limit, rather than guess, is inside.
