Big Surprise today,Saturday 9/05/15. The roofers finally turned up to repair the damn roof. Because the old one was asbestos sheet,the whole shop had to sealed up while they removed every on top of the building. Amzingly it took only 8 hours to strip the old roof off and fit insulation ,then fit the new Zincalume roof.
OK, ,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.
Next 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.
This is the conduit where the vacuum lines for the central locking pass on the 280SE 3.5 Project… pretty neat and an example of the over engineering on Mercedes of the past.
The 6.3 was misfiring badly under acceleration. a big disappointment for the owner ,who had spent a lot of money getting the injection pump rebuilt and the ignition converted to electronic . So, when working under thecar replacing worn rubber joints and worn drive shaft parts I spotted the squashed fuel line .The picture on the right shows a really bad dent in the main fuel line . The entire line will have to be replaced ,and i am thinking this is probably the cause of the misfire
The Drive shaft with it’s new staked unijoints and rubber center support bracket .
The wiring in this ute project has also suffered because of the bicarb getting into insulation and plugsAdd Media . i had to replace the entire fuse box because of corrosion.
A long job,entailing unscrewing each terminal,then cleaning as much of the bicarb out of the terminal end or replacing those too badly damaged and replacing the ring terminals with new ones.
i still have to repaint the fuse box mount panel and repair the footwell light,but in the meantime,I will be removing the steering xcolumn to get the bicarb out of the column housing and checking the top bearing.and gearshift bushing..
But First, the heater must be installed.
The screen demister ducts have been cleaned or replaced as necessary with new antisqueak felts.
. The controls are fitted to heater before it is fitted into the car.
all of the foam seals and matrix rubber mounts have been replaced in the heater.
These are a pretty tight fit,but the heater goes in first ,followed by the demister ducts.. The column must bwe removed and repaited too. The handbrake is off,to replace the cable and clean up the shaft that has reacted with the bicarb.
Nothing beats driving a vintage Benz on a long trip.
This year was no exception and I took my 300SEL 6.3 to Gladstone to stay at a relatives and enjoy a bit of seasonal cheer. The car ran great ( except for a blown fuel line which wasted $100 worth of fuel on the road) but I suspect the injection pump ,which I had rebuilt some years ago at great expense ,is running far too lean. how long since exhaust pipes were this color? or are they slipping lead back into high octane fuel?
That’s my 6.3 at Rockhampton where we spent a few hours looking for an RV for a relative.
