Hi, I have recently bought a w123 300d because I miss my fathers old 240D Mercedes.

I will post pictures later.

Well first diagnosis has been done:

- All the fluid (some are factory even)

- All coolant hoses are hard as wood. Radiator need also to be replaced and thermostat.

- Dreaded Vacuum issue.

- fuel guage wapping under 1/2 (cluster replacement time anyway)

- High beam isnt working (some electric fault)

- Indicator lens are broken

- A/C is missing some lines and condensor

- Valve cover is sweating like mad

- Rust (common places) needs rewelding

- Front windscreen has a big star in it

- Car is left lower than right?

- Paint is bad maybe a detailing needed

- Interior some bits needs to be redone

- Some of the plastic interior parts are broken

- Needs lubrication (all hinges and hood release)

- Front left makes a noise when steering (steering joint?)

- Diesel purge

---------------------------------------------------

Upgrades:

- Rear headrests
- RPM meter original Diesel (so need the diagnosis plug etc.)
- Final drive upgrade
- Flexdisc
- Shocks
- steel brake lines
- wheels (barocks
- instrument cluster
- Some of the Wiring
- battery vent (so the tray wont rust anymore)

That's for now.

Here are the parts and fluids I bought before the car came in:













Some Original tools (hooks) I bought 15 years ago.

Just had some time to work on the W123 so started with the fluids and filters:

Old air filter had to be cut when removing it.















Battery vent extended. Need to have a look where to put the tube.









Some pictures from the backseat and C pillar.

I also did the power steering fluid aswell:

Some parts arrived:

Wiring rpm meter:









fuel cap:



New rubber ring:



I had to adjust the odometer to the correct mileage and I did scorched the axle a bit so its fixed now.















This replaced the rubber sealing ring

Finally I can shutoff my engine by key and fixing the rest of the vacuum of course:



So I swapped over the 280E speedo into my 300D.

But, my clock doesnt work.......

02.09.2018 just received my tachometer plug





crankshaft sensor and repair star:



15.09.2018 cleaned up the drain well.

23.09.2018 checked underneath and repaired my speedometer glass.





























Tellerbak lens geplakt aangezien ik er nog een keer eraf haalde en stuk ging. Zit weer goed vast.



some one way valves

17.10.2018

Cleaned the tank leveller guage.















Broke into the trunk through the rear lights mine was cracked so needed to replace anyway.

22.10.2018

Swapped the w116 tachometer mechanism into my w123 backplate thanks to peachparts. soldered also two new caps into the clock

30/10/2018:

Fixed my headlight main beam (wiring):



Fuse of the Glow spirals replaced:





Hooking up wiring for the tachometer:



Repainting some of the parts to the original state:




Warm white LEDs:



5/11/18

Bought a Co2 fire extinguisher if I ever get a runway I can stop it:



8/11/18 Bought a clean and rust free battery tray:



10/11/18. Fixed the not warming up thermostat:

Seems to be rotten away:





5 November 2018:

New AGM battery in



9/11/18

Replaced all the fuses due age:



9/11/18

Finally Original MB hoses in:







Also fixed the license plate light holders:

I want to adjust the time back to winter time and guess what? The adjuster breaks off



Tried to reglue it


Then I tried to make two clock one by using the w116 print and the w123 mechanism.



Left one is W116 300sd and right one w123 300d
Both has the same resistor on the tester.







tried to replace all the components but, doesn't work.



This one works:



Comparison of the chip blanks



120ohm on the main resistor 118.9 is <5% is pass.



Then I greased everything so that it won't rust





Back to one piece



I replaced the caps before already.



Then I tried to hook up the tachometer to see if it works:



Fan 1500rpm > tachometer 1500rpm

Nice to see some good works being done here .
