Mercedes Benz 300SEL 6.3 repairs

Leave a reply

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_0241

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.

Mercedes Benz 220SE Coupe conversion

IMG_0230

progress has been held up while i rebuild my Mig welder . But in the meantime I have begun the task of anchoring the cowl to the coupe shell. It involves a lot of fabrication of the various small bits to be welded into the body .Starting with the right A pillar.

IMG_0229 more of the W126 A pillar was removed,back to where it was originally welded to the cowl. This will make a cleaner stronger joint.

IMG_0228IMG_0226

These will be plug welded then lap welded around the edges.

IMG_0225

IMG_0224

The last part will involve welded a second peie over the top of the top panel which will connect the inner guard (on the right) to the cowl.

Mercedes Benz W108 Steering box tools

Leave a reply

IMG_0231occasionally refitting the heavy steering box into a Mercedes W111,112,113,108 or 109 requires a lot of time wasting wrestling to get the box sitting correctly .And that means ensuring the steering box,the column and steering linkage is all in sync. if it’s not ,strange things happen. .The steering will feel light and vague,the indicators will either turn off too soon or not at all and so on.

So,this brings me to the little tool i made today . it screws into a special hole in the power steering box and holds it in the dead ahead position. IMG_0237 Turning a M8x1 thread in a 400mm swing lathe is an odd exercise….

IMG_0236

That’s only part of it. The column must be locked too,to enable the column to also sync properly with the steering box ,again so the indicators turn off at the correct time.

IMG_0233

This is a steering column (upside down) .The thing I am holding is a lock pin which fits into a special hole in the steering shaft and prevents it moving while it is being installed.

6.3 300SEL Service

Leave a reply

IMG_0214Little details..

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 .

6.3 major service

Leave a reply

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_0201

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.

IMG_0203 IMG_0204 IMG_0206\

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

IMG_0207

IMG_0208a bit hard to see in this shot,but this is a heat sheild uder the drivers foot well,which will be removed and cleaned so it does it’s job properly.

Leave a reply

Every now and then I find stuff I  never knew I had so I have and one example is a sump protection plate. for any W111 Chassis Mercedes. .IMG_0193 IMG_0194i even have the front brackets which are damn rare.

And…It may be sold already.

Mercedes 280SE 3.5 ute, brakes and air con overhaul

Leave a reply

The booster was a bit rusty looking so i t has been decided to strip it down. and clean it up .After pulling the master cylinder off,it could be seen that the booster was full of fluid….. IMG_0137 IMG_0139as can be seen ,the booster contained close to 3 liters of brake fluid.

tIMG_0141

The steering column was then pulled and examined,more BiCarb! ,and the paint had been attacked and needed redoing . IMG_0142 IMG_0143

IMG_0145 IMG_0146 IMG_0149This picture shows the extent of the biCarb inside the gearshift mechanism.

Under the booster,the firewall and the right front chassis rail join was rusted out . The rusted metal is removed and replaced with fresh metal.

IMG_0157 IMG_0158 IMG_0159 IMG_0160

Nest Job was to rebuild the Air con and once the housing was opened up,it could be seen that the evaporator was full of fluff and BiCarb.

IMG_0161 IMG_0162 IMG_0163 IMG_0164

IMG_0165IMG_0167

The bottom of the evaporator housing was rusted out so a new peice of Zinc anneal was welded into place to repair the bottom .Condensation won’t leak into the car now,.IMG_0168 IMG_0169the evaporator has been flushed and the fins cleaned and straigfhtened .Once the new bottom was welded in ,the housing and panels were zinc primered,then primed and fisnh coated in black .The foam liner was replaced and the unit reassembled and the fans tested .

Mercedes W108 ute.. wiring repairs.

Leave a reply

circuit_diagram

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.

IMG_0123

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.

IMG_0126

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.

IMG_0118 . The controls are fitted to heater before it is fitted into the car.

IMG_0121all of the foam seals and matrix rubber mounts have been replaced in the heater.

IMG_0119

IMG_0127

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.
