1980 W123 A/C issues

A/C doesn't work, the DEF is the only switch that works, used a jumper wire & started the compressor, works fine. There is no power at the switches on the dryer & no power at the switches on the CC console, also, the vacuum hose that goes into the 6 point distributor does not hold vacuum, what are some things I can check before taking drastic measures.

Upgrading Alternator Amps for DTC

Greetings from Columbus, Ohio. My 1982 Mercedes 300D Turbo Diesel has a glorious Mercedessource DTC system! Only problem I am experiencing is that the alternator can not reliably keep up with the electrical demands. What ampere level would be a good upgrade (150 amp to 300 amp?) and do you have any specific brand/model of alternator you recommend? Trying to eliminate the risk of producing too many amperes as well (if that is even a concern). Many thanks and keep on Greasing! --- Chris Konik

AT Metal Cooler Line Leak

I have an '83 W123 & have just noticed a fast drip coming from the area of the automatic transmission cooler line on the right/passenger side - along the engine & at the very point where the line bolts to the oil pan. I assume that this is the same problem mentioned in the "Alert" section. Question is, aside from the preventative fuel hose replacement, what sort of actual "fix" can be applied to stop & solve the leak? Has anyone fully repaired a leaking AT cooler (metal) line? thanks, Kieran- NJ

1983 300D auto trans won't separate from engine ??

I have removed the engine & auto trans from a 1983 (built 12/82) 300TD. After removing all bell housing bolts I expected to be able to slide the transmission away from the engine. No luck. It appears to be stuck at about 3/4" to 1" seperation. Is there something I missed to release the trans or does it just need to be pulled apart with more force? -Mike
