Mercedes Benz Maintenance Manual USA Model Year 1972-1980 | PDF
Technical maintenance documentation for US-market classic Mercedes-Benz passenger cars, especially useful for scheduled service, adjustments, lubrication, tune-up and preventive inspection tasks.
This edition covers a wide range of Mercedes-Benz models sold between model years 1972 and 1980, including sedans, coupés, cabriolets, roadsters and luxury versions from the W100, W107, W108, W109, W111, W113, W114/W115, W116 and W123 series.
The manual brings together maintenance procedures organized by technical groups and job numbers, with written and illustrated instructions, service charts, adjustment data, filling capacities, fuels, lubricants, coolants, special tools and factory-specified tightening torques.
Because it covers shared chassis, engines and technical systems, it may also be useful as a reference for equivalent European and other-market versions, provided that differences in specification, model year, equipment and local regulations are always checked.
