1989 Mercedes-Benz 560SL Service & Repair Manual

• Vehicle and engine coverage: Centered on the 1989 Mercedes-Benz 560SL (107.048) with the M117.967 5.6L V8, CIS-E fuel injection, and computer-controlled magnetic ignition. The shared 1989-90 V8 engine article also identifies the 420SEL with M116.965 and the 560SEC/560SEL with M117.968.
• Engine repair procedures: Covers engine/transmission assembly removal and installation, intake and exhaust manifolds, cylinder heads, timing chain and tensioner service, valve-timing correction with offset Woodruff keys, camshafts, rocker arms, hydraulic lifters, valve gear, pistons, crankshaft bearings, seals, oil pump, and water pump. Component-specific torque tables, clearances, inspection limits, and adjustment data are included.
• CIS-E and EZL fault diagnosis: Provides theory of operation, preliminary and fuel-delivery tests, California and Federal code retrieval, no-code symptom diagnosis, sensor and relay checks, idle-control testing, EGR/EVAP checks, sensor-range charts, injector waveform interpretation, and a dedicated 560SL CIS-E wiring diagram.
• Transmission and rear-axle work: Includes W4A020/W4A040 automatic-transmission diagnosis, shift-point and operating-pressure checks, transmission removal, axle-shaft and CV-joint service, standard and limited-slip differential disassembly, and pinion-depth, bearing-preload, backlash, and gear-contact-pattern procedures.
• Brakes, steering, and suspension: Details brake-pad, caliper, rotor, master-cylinder, and parking-brake repair; Bosch ABS pre-diagnosis and component testing; power-steering pump and recirculating-ball gear overhaul; front and rear suspension R&I; ride-height adjustment; and wheel-alignment specifications and procedures.
• Climate control, electrical, and SRS: Identifies the 560SL's Nippondenso 10-cylinder compressor application and covers automatic A/C impulse readout, sensor and vacuum testing, component R&I, and 560SL wiring. Separate articles address charging and starting, parasitic draw, electrical component locations, cruise control, wipers, instruments, SRS diagnosis, and post-collision inspection.
• Diagrams and test support: Notable examples include the Cylinder Head Tightening Sequence, 420 & 560 Series Vacuum Hose Diagram, 560SL Automatic A/C Wiring Diagram, 560 Series ABS Wiring Diagram, Exploded View of Mercedes-Benz Drive Axle Assembly, and Cross Sectional View of the Steering Gear.

This Mitchell Repair Information Company compilation is a 1,098-page PDF set made up of 73 separate article files. Its engine-performance introduction expressly addresses professional automotive technicians, and the depth of the set reflects that audience. Many procedures assume access to a DVOM, lab scope, refrigerant recovery equipment, model-specific test adapters, and normal workshop lifting equipment.

Coverage Structure and Shop References

The files combine 560SL-specific material with shared Mercedes-Benz articles and general repair references. The shared articles are useful where the 560SL uses the same system family, but their broader model listings should not be read as full-vehicle coverage for every 420 or 560 variant. Several long inspection sections are all-makes Motorist Assurance Program guidelines, while the engine-overhaul and troubleshooting articles include general procedures that supplement the Mercedes-specific repair information.

Referenced service tools show the level of work expected. Examples include Spring Compressor 123 589 03 61 00 and hydraulic-lifter Test Gauge 100 589 04 23 00, ABS Test Adapter 126 589 09 21 00, SRS Tester 126 589 10 21 00, and rear-axle Assembly Mandrel 116 589 18 61 00. Tool references identify equipment called for by the procedures; they do not indicate that tools are supplied with the PDF files.

Manual-Specific Repair Cautions

The M116/M117 valve-train article flags a rocker-arm interchange trap: replacement arms must have the lifter-end chamfer that prevents contact with the hydraulic-lifter retaining cap, and new rocker arms are not to be mixed with a used camshaft. In the rear axle, overtightening the pinion nut crushes the collapsible preload spacer beyond reuse, requiring pinion removal and replacement of the spacer.

A/C service requires approved refrigerant recovery/recycling equipment before the circuit is opened. SRS and ABS work also depends on the system-specific disabling and depressurizing precautions in the set; the SRS section limits testing to approved equipment to avoid accidental deployment or component damage.

PDF Set Page Breakdown

The 1,098 PDF pages are organized as follows: identification, general reference, and maintenance, 78 pages; engine, CIS-E, ignition, emissions, and cooling, 309 pages; air conditioning and automatic climate control, 106 pages; transmission, driveline, and rear axle, 80 pages; brakes and ABS, 64 pages; steering, suspension, and alignment, 181 pages; electrical, accessories, and restraint systems, 204 pages; and general multi-system troubleshooting, 76 pages.

This is a Mitchell repair-information compilation rather than a single Mercedes-Benz factory workshop manual. Automatic-transmission coverage focuses on diagnosis and removal/installation, not a complete internal transmission overhaul. The set also does not include full body, convertible-top, upholstery, or paint-repair chapters.
