Vath Mercedes-Benz 300 SEL

Old, but good as new - VÄTH Motorentechnik Company get their hands on a 1953 300 SEL.

This majestic W109 is powered by M100 V8-engine with 6.3 liter engine with 246 hp and 4.000 rev/min in combination with torque of 510 Nm at 2.800 rev/min. The acceleration from standstill to 100 km/h is achieved in 6.5 seconds and this beauty. The body and interior were partially overhauled, while the whole engine and the axles were completely overhauled. Also engine compartment was restored.

VÄTH Motorentechnik works upon request on all Mercedes-Benz vehicles from 1953. Restoration can be made on all the extensive parts: complete engines, parts of engines, fuel injection systems, transmissions, differentials, drive shafts, exhaust systems and control equipment.

The general overhaul and repair of an engine block include disassembly, cleaning and inspection. The engine block is milled and then the cylinders are drilled and honed. The crankshaft is smoothed, polished and balanced. The crank mechanism is made less heavy along with the flywheel. Piston rods are modified and the connecting rod bush is renewed. Pistons and oversize pistons are custom made. Connecting rod bearings and crankshaft main bearings as well as seals, chains and wheels are renewed, and if it is necessary – oil and water pump are also renewed.

Cylinder head changing and general overhaul begins with disassembly and cleaning, too. Then come the footprints of the cylinder heads (crack detection). Then comes milling. The valve seats are milled, outlet side is milled, seat rings are pressed and the valve contour is milled into the seat ring again. Finally the valves are grinded and the leak test is performed. Then the controls are renewed. With the hardened valve seat rings the lead-free modification is possible.
