Get the best from the sassy Mercedes R107
The R107 roadster and C107 coupé launched in 1971. The first came with 3.5-litre V8 power, but 3.8-, 4.2-, 4.5- and 5.0-litre V8s followed. Straight-six 2.8and 3.0-litre versions also joined the range. The SLC coupé ceased production in 1981, but the SL roadster continued until 1989. Bosch D- and K-jetronic mechanical fuel injection was used until 1985, when it was ousted by Ke-jetronic electronic injection.
What’s it like to work on?
Many aspects are easy to access and work on. However, the V8 does fill prettymuch all available under-bonnet space, which means that some jobs – such as changing the spark plugs or re-bushing a worn accelerator linkage – require time and patience aplenty. The same goes for some parts of the suspension and running gear, especially if you find rusty fasteners.
Parts and support
Original Mercedes parts are available through dealerships. The quality is high – but so, sometimes, are the prices. Independent specialists such as The SL Shop (theslshop.com) and Starpartz (starpartz.co.uk) offer parts and expertise. Strong club support comes from the Mercedes-benz Club (mercedes-benzclub.co.uk) and Mercedes-benz Owners (mercedesclub.org.uk).
This applies to…
Our guide features a 1984 500SL, but most of the procedures involved apply to the rest of the R107 and C107 range. Track down a manual for data and specific processes that apply to your model. Many of the engine and transmission aspects are similar for contemporary Mercedes V8 saloons.
