Target Audience:
Jaguar XK140 owners, independent repair shops, classic car restorers, and automotive enthusiasts seeking detailed repair and maintenance information.
Manual Value:
Provides official, manufacturer-level repair data, enabling owners to perform high-quality maintenance and repairs, saving significant costs compared to specialist workshops.
Accuracy:
Vehicle-specific, accurate, and concise text with diagrams, illustrations, and wiring schematics.
Comprehensiveness:
Covers all major topics required for mechanical and electrical servicing and repair.
Usability:
Step-by-step instructions designed for both experienced mechanics and owners with basic mechanical skills.
Primary Coverage:
Service, Repair, Workshop
Included Sections:
General Information, Engine Mechanical, Engine Electrical, Emission Control, Fuel System, Clutch System, Manual Transaxle, Automatic Transaxle, Driveshaft and Axle, Suspension, Steering, Restraint, Brake System, Body (Interior/Exterior), Body Electrical, HVAC
Estimated Page Count:
Likely 500+ pages (typical for comprehensive workshop manuals of this era)
Type:
Workshop Manual / Service Repair Manual
Engine Mechanical:
Detailed overhaul procedures for XK engine variants (e.g., 3.4-liter inline-6), including cylinder head, block, crankshaft, pistons, connecting rods, camshafts, valvetrain, timing gears, lubrication system, and cooling system.
Engine Electrical:
Ignition system (distributor, coil, spark plugs), starting system (starter motor), charging system (dynamo/alternator, regulator), lighting system, instrumentation wiring, and horn.
Emission Control:
Information on original emission control systems if fitted, likely very basic for this era (e.g., crankcase ventilation).
Fuel System:
Carburetor servicing (likely SU or Weber), fuel pump operation and maintenance, fuel lines, fuel tank, and fuel filter.
Clutch System:
Single-plate dry clutch operation, adjustment, and replacement of clutch disc, pressure plate, and release bearing.
Transmission:
Details on the Moss (pre-synchromesh or early synchromesh) manual gearbox and the optional Borg-Warner T-85 automatic transmission, including overhaul, adjustments, and fluid specifications.
Driveshaft And Axle:
Servicing of the open driveshaft, universal joints, rear axle assembly (Banjo type), differential, and half-shafts.
Suspension System:
Front independent suspension (wishbones, torsion bars, kingpins, shock absorbers), rear live axle with semi-elliptic leaf springs, bushings, and steering geometry.
Steering System:
Worm and roller steering box, steering column, track rods, tie rods, and steering wheel mechanism.
Restraint System:
Likely minimal for this era; may cover seat mounting and basic lap belts if factory-fitted or optional.
Brake System:
Hydraulic drum brakes (Girling or Lockheed) for all wheels, including master cylinder, wheel cylinders, brake shoes, drums, lines, and bleeding procedures. May also cover early disc brake applications if fitted on later XK140s or optional.
Body Interior Exterior:
Body panel alignment, door mechanisms, hood (convertible top) operation and repair, trim, seats, dashboard, bumpers, grille, and exterior trim components.
Body Electrical System:
Headlights, taillights, turn signals, interior lighting, horn, wipers, washers, electric window mechanisms (if equipped), and dashboard instruments.
HVAC:
Heating system (heater matrix, blower, ducting). Air conditioning was not a factory option during this period.
Maintenance:
Routine servicing, lubrication schedules, fluid changes (engine oil, gearbox oil, axle oil, brake fluid, coolant), filter replacements (oil, fuel, air), spark plug replacement, ignition timing adjustment, valve clearance adjustment, and brake adjustment.
Troubleshooting:
Diagnostic procedures for common problems related to engine performance, ignition, fuel delivery, starting, charging, brakes, steering, and electrical systems.
Repair:
Step-by-step instructions for component removal, disassembly, inspection, repair, reassembly, and installation across all major vehicle systems.
Diagnostics:
Systematic approaches to identifying faults, likely using visual inspection, measurement tools (multimeters, feeler gauges), and listening for abnormal noises.
Depth:
Comprehensive, covering everything from basic tune-ups to complete engine and gearbox rebuilds, with detailed specifications and tolerances.
Oil Change Interval:
Recommended every 3,000 miles or 6 months, with specific oil viscosity based on ambient temperature (e.g., SAE 20W-50).
Grease Points:
Regular lubrication of chassis grease points (kingpins, steering joints, suspension bushings, driveshaft UJs) every 1,000-2,000 miles.
Engine Oil Capacity:
Approximately 13 imperial pints (7.4 liters) with filter change.
Brake Fluid Type:
DOT 3 or DOT 4 hydraulic brake fluid (check manual for specific type recommended).
Gearbox Oil Type:
GL-4 Hypoid Gear Oil (e.g., SAE 90) for manual transmission; specific automatic transmission fluid for Borg-Warner units.
Coolant Type:
Ethylene Glycol based antifreeze mixed with water (50/50 ratio).
Common Wear Items:
Kingpins and bushings (suspension wear), clutch wear, brake cylinder seals, radiator leaks, fuel pump diaphrams, and wear on Moss gearbox synchromesh (if applicable).
Electrical Reliability:
Original wiring harnesses can degrade over time; fuse box issues and dynamo output may require attention.
