617's out

Some Parts Swapping

I've been swapping parts from the 300d to the 240d. Below are the headlamps after changing out the yellow fogs and the plastic surrounds. 

List of other items swapped but no pics :-(
Passenger mirror. No more distorted glass.
Exterior door handles and latches.
Trunk lock and latch.
Ignition lock cylinder.
Chrome trim on top of door cards. The 240d has no chrome trim.
Plastic bins on front door cards. The tabs holding the old ones to the door card were cracked.
I also swapped the cruise control computer (the only computer in the 240d?). Cruse control is now functioning.

Time, Place, Cash.

The three items in the title of this post came together and allowed me to purchase a parts car for the amount of $500.

An 84 300d Trubo. Finally, all of the broken pieces I need for my 240D! With 220K, this car is running smoothly and can be moved around under its own power. As the story goes, the previous owner swerved to miss a racoon, and ended up putting the front driver wheel into a ditch. The metal structure of the strut tower is torn and the upper and lower control arms are bent.

 I've began the process of dismantling.

How about a manual 240D with a OM617 swap?

Clean Carpets and Coco Mats

After attempting to purchase a carpet kit and being ripped off by mercedesautoworks.com to the tune of around $300, I decided to simply remove my carpeting and power wash it. The results were pretty amazing. Once removed, I scrubbed the carpets with Simple Green, and went over them a couple times with the power washer. I should have spent that $300 on a power washer....

The results were amazing, and the best part of my new interior treatment are the floor mats. There is a company in SC which makes excellent floor mats. These are not cheap, but you get what you pay for. check them out at cocomats.com.

300K

May 7th, 2015. 300,000 miles achieved.

Rebuilding Injectors

Since I've owned the Benz, its had a rough idle and sometimes a knock here and there. I purchased new Monarch nozzles form Mercedes Source and rebuilt my injectors following the procedure in Kent's guide.

 Testing each injector with the hand pump on my work bench, I found one injector was squirting like a cheap dollar store water gun, rather than misting correctly.

 Old dirty nozzles

After the rebuild and balancing of the injectors, my engine runs smoother than it ever has. Also, there is no noticeable smoking at startup!

Vacuum Pump

297,XXX miles and the vacuum pump has stopped functioning. Go figure. I began investigating the vacuum pump when the breaks became manual and the engine wouldn't stop without using the emergency stop lever.

I verified the master would hold vacuum (lots of pumping with the hand pump) and that the hard lines passing through the firewall which weren't golf T'd off :-/ would also hold vacuum.



I could not however maintain vacuum on the hard line at the pump. (I think this is accurate. I'm writing this months after taking the photos and completing the job)

Pump disassembled (above)
Old seals and check valves (below)

(Above) Cam which the pump's bearing rides on. In the picture there appears to be wear but it was smooth as glass.  

Disassembled pump. (Above)

This is the wall of the cylinder which the pump's piston operates in. Again, the surface was smooth as glass and shined like a mirror. 297,XXX miles.....







Pump reassembly with new check valves and gaskets.

Put the one way check valves back in facing the correct way.




Complete. Ignore my hanging A/C compressor.
