Mercedes Benz 300SEL 6.3 restoration Project

IMG_0058 IMG_0059 IMG_0060

This is RHD 6,3 #2206 . The engine is incomplete and the drivers side sill/rocker  is rotten but the rest of the car is surprisingly sound but in need of a full restoration .RHD 6.3’s are too rare to part out and i would rather restore this car anyway….. or build a historic racer for weekend fun.

A great score!

For my own 6.3 I needed a new radiator and had thought of eitherr making a newer one out of alloy but then i found this on ebay..

A brand new old stock 6.3 radiator for .  Not $5000 AUD , Not $2500 USD as demanded for a new one but …………. $275.  Still in it’s original box.

Mercedes Benz 300SEL 6.3 repairs

IMG_0239OK, ,more progress on the 6.3. The fuel is being replace and this pic shows why. Many years ago someone has crushed it by lifting the car incorrectly with a hoist ,jack or….forklift. In fact it was squashed in many places.

next pic shows one of the other crush points.

IMG_0242Next job is the Fuel lift pump.

As can be seen in the pic,the pump was mounted solidly and is 150mm too high,meaning that once the fuel level drops to 1/3rd tank level the pump was starting to starve for fuel . These pumps are not a suction pump,but a pressure pump.

6.3 major service

IMG_0199Up on the hoist, the steering box coupler has been replaced ,Other jobs required are a new flex disc ,drive shaft universal joints and center support bearings. The diff support pivot bush was worn out so the diff was removed.

IMG_0202The brake hold down (or anti dive mechanism ) device was stripped and overhauled with new seals and bushes. The shafts were a bit stained from water getting in but otherwise OK.

The torque arm bushes will be replaced as these look to be the original do nuts and are as hard as rocks.
