85 300TD Rear Wheel Bearing Race Problem
Have run into a real problem on my 85 300TD...apparently my right rear wheel bearing seized at some point, shattered the race (well, two pieces) and the new race won't press in (just slides in by hand...no interference fit.) Do I need a whole new wishbone back there? Kinda looks like it....can these even be had?
Given the rust issues...I'm wondering if it's time to jury-rig it by JB-Welding the race into the carrier to get the race in and relegate the car to short trips and focus on my W124.
Thanks.

77 300D Engine Transplant options
recently, my 1977 300D W123 diesel engine seized. Ive come across a 1984 300SD turbo Diesel W126. Can I transplant the turbo Diesel complete into my 1977 w123. I planned to transplant the engine, transmission, and rear axel.
Will this work? The reason Why I ask is because I am not sure if there is any wiring, or vacuum lines that wont interchange, or need to be added. Please advise. Thank you for taking time to help.

85 300TD a/c compressor won't work
I recently converted my a/c on my 85 300TD to R134. The system had a huge leak in the suction hose, which was replaced. The system was evacuated and I added three 11-ounce cans of refrigerant, but the compressor will not turn on. It was working fine before, so I was wondering if there was a switch or something that is not functioning properly, or if more R134 needs to be added.

1984 300D Decrease in mileage
My Benz "Old Yella" had recently slipped a little in the miles per gallon dept. I have developed an obsession with the car and stay right on top of things mechanically so I was a little puzzled. The air filter was coming up on my periodic maintainence schedule so I decided on trying out a K+N. I usually change air filters after about 20,000 miles of use. This figure is flexible as all driving conditions are not the same. Dust, road salt and sand can all gather in the filter and constrict air flow which is essential to internal combustion engines.
