Troubleshooting electrical circuits using wiring diagrams, testing electrical components (switches, solenoids, sensors), and diagnosing starter/charging system issues.
Troubleshooting:
Diagnostic flowcharts and procedures for identifying the root cause of common drivability, starting, and electrical issues.
Timing Belt Service:
Procedures for chain removal and tightening (note: Rotary engines do not have timing belts in the conventional sense, this likely refers to accessory drive belts or internal chain components if applicable to specific early designs, or is a generic inclusion). If it pertains to the rotary's oil pump drive chain, detailed instructions would be present.
Diagnostics:
Computer diagnostic trouble trees and charts (may be rudimentary for the era, focusing on identifying fault codes or operational parameters).
Front End Alignment:
Detailed procedures and specifications for caster, camber, toe, and thrust angle adjustments.
Depth:
Comprehensive from basic maintenance to full engine and transmission rebuilds, including detailed electrical schematics and diagnostic procedures.
Displacement:
1.16 L (12A) - Effectively 1.16 liters of displacement, often referred to by its rotor housing diameter and width (12A).
Horsepower:
Typically around 110-125 hp depending on model and emissions controls.
Torque:
Approximately 110-120 lb-ft.
Carburetion:
Dual Hitachi downdraft carburetors (common), later models may have variations. Some performance variants might have aftermarket or dealer-installed Weber setups.
Oil Type:
Specific rotary engine oil (e.g., SAE 20W-50 or 10W-30, depending on climate and manufacturer recommendation). Critical to use oil suitable for rotary apex seals.
Oil Capacity:
Approximately 4.5-5.0 US quarts (4.3-4.7 liters) with filter change.
Coolant Type:
Ethylene glycol-based coolant (typically 50/50 mix with distilled water).
Spark Plugs:
Typically two spark plugs per rotor housing for optimal combustion. Specific plug types and gap settings are critical and detailed in the manual.
Oil Change:
Typically every 3,000-5,000 miles (5,000-8,000 km) or 3-6 months, depending on driving conditions. More frequent changes are often recommended for rotary engines.
Spark Plug Replacement:
Refer to manual for specific intervals, often around 15,000-30,000 miles (24,000-48,000 km), but critical to use correct types and maintain gap.
Coolant Flush:
Every 24,000 miles (38,000 km) or 24 months.
Transmission Fluid Change:
Every 30,000-50,000 miles (50,000-80,000 km).
Brake Fluid:
DOT 3 or DOT 4.
Grease:
Lithium-based multi-purpose grease for chassis lubrication points.
Apex Seals:
Premature wear of apex seals can occur if the engine is not properly maintained, overheated, or starved of lubrication. This is a critical area for rotary engine health.
Carburetor Issues:
Vapor lock, vacuum leaks, and maladjustment of the dual carburetors are common issues affecting performance and fuel economy.
Rotary Specific Maintenance:
Importance of proper lubrication (oil injection system if equipped, or pre-mix for some racing applications), avoiding 'hot restarts' immediately after shutting down a hot engine, and maintaining correct oil levels.
