'73 220D questions

I have a 220D, recently aquired, that i am a little unsure of some things and would very much appreciate some answers:

1: how do i maintain the oil bath air cleaner? how do i fill it?

2: do i check the ATF while it is running or cold? where is the fill plug for changing fluids?

3: the A/C was removed from my car and there is only a single, and bent bolt holding the alternator away from the engine. it is held on by a 19mm bolt on the engine and attaches to the top of the alternator to adjust belt tension. this seems a little awkward and i don't think it is right, is it?

thanks in advance!

You have a great car but you'll soon find what a joy it is to clean the air filter

My friend helped me clean my air filter at his shop, where he could use an industrial-size solvent tank. It was a messy job. I can't remember what he used in the solvent tank. You remove the whole air cleaner, drain the container the element sits in, & get nasty black oil everywhere. Once it and the element were completely clean & dry, I just put the element back and added motor oil to the "full" mark (you don't fill it completely) and put everything back in the car (also a bit tricky with the clamps).

ATF -I don't know as I have a manual transmission. With my other car
(which is an automatic but not a Mercedes), it needs to be running while checking the fluid.

I don't know what to say about the alternator arrangement you have, either, as it obviously was modified; mine is stock but the AC bracket is a nightmare to put on and off...maybe that's why yours was removed.

am i filling the air element or the airbox it is in . this thing is weird. where is the fill mark and with what type of oil?

most auto trans you check it while hot, and the motor running. but this thing is old so i thought i'd ask.

i bet someone popped the bracket out and rigged this thing up like this. it looks sketchy. i think i will re-install a junk yard bracket when i find one. per chance, does anyone have a picture of that the area should look like? maybe from a non-a/c car?

The alternator setup you described is correct. The bolt with the 19mm (I think) head is attached, but not tight; then the threaded end of the bolt has a mechanism that is loosened then turn the top nut for proper tension and tighten both bolts.
The oil bath cleaner basically fills up to the first or second ridge (it's marked on the inside of the housing at the bottom. It's only an inch or two of oil, but do find the mark. It is there. If you're in a cold climate I'd use an oil that doesn't turn viscous in the cold.
I have a 4-speed so don't know how your auto trans fluid is checked. Look on the stick and see if there is a "hot level" and a "cold level".
Check back in if you still have problems.

i will look into the oil level. i thought this thing was blowing oil out the intake!

the 19mm bolt provides a pivot point, i see. is your bolt straight as an arrow? mine is bent...

thanks guys

Yes, the bend in the alt rod is correct.
