I drove w110 gassers for 35 years. In 2014 it was time to upgrade to w123 diesel. My factory manual doesn't show the zerk locations but I remember them as:
3 on each front kingpin. Top, middle, and bottom
4 on each side on the upper and lower control arms where they attach to that front assembly
1 on the drive shaft right behind the transmission
Maybe 1 on the hinge point of the rear axle
I used a plain old grease gun with a flexible hose outlet. The zerks should be the same as American. The grease gun goes over the the little bulb top of the zerk. I always assumed the pressure of squeezing made the nozzle of the gun grab the zerk to prevent grease squeezing out. If grease comes out where the nozzle is on the zerk, it is either not on all the way or the grease passage is plugged solid. I pumped grease until I got just a little burp of grease somewhere in the joint. My 190's got grease with every oil change. They were up on jackstands so I could turn the wheels right and left to reach everything while the oil drained. The filter is under the engine so you have raise the car.
My manual is the 3 volume, 4 ring binder version for all models from 1959 to 1968 except the 600 and the 300SL. PM me if you like those kind of things and want to talk about buying it. I am in Portland, OR.

15w-40 Rotella or DELO would be excellent, I'd stay with dino on that car. Greasing the chassis...there should be a lot of Zerk fittings, yes regular grease gun. Don't use old grease get Lucas, Mobil 1 etc. That car may even have greaseable door hinges requiring a needle adapter for the grease gun.

Remember to check and change? the oil in the injection pump and the air cleaner.

Good luck!!!

Here's a chart I stole from somewhere else on the forum. Happy lubing! I do it every 6 months, I also drive my car every day.
All fintails have greaseable door hinges, mine took some heat to get them to circulate grease.

So lubricating things like water pump & distributor shaft? How does that work?

The original style water pumps had a fill and check plug in the pump housing to fill with motor oil. They did not use sealed bearings like new style water pumps but ran in an oil bath instead. Had forgotten about that till I read it here. As far as the distributor shaft, not sure on the Mercedes as I have diesels, but I know on some older american vehicles the distributor had a little lid you flipped open to pump a few drops in to lubricate the shaft.

For engine oil, I use mainly Delo 15W-40 but have also used Rotella on my Mercedes diesels. Just make sure the oil is rated for diesel engines. I think Chevron Delo was actually recommended by Mercedes in the day.

Like I said before, there are grease zerks everywhere on the suspension. If they have not been greased for a while, you may not be able to get grease pumped in. If that turns out to be the case, I highly recommend you remove the zerk and do what you can to dig out the crud and get it to take grease. The parts will wear if not kept greased.

Actually I forgot mine is a diesel too so forget about the distributor shaft!
In looking at the locations of these grease points it looks like I have my work cut out for me!

Oh, someone earlier mentioned greasing with every oil change since they drive is my intention to get this car up to snuff & use it for getting to work, groceries etc. Its a slow moving city with not much traffic so speed won't be an issue.

Hi, does anyone have a diagram for fuse box info?

I mentioned that my wiper motor doesn't work but I have some other electrical issues (dash gauges, horn).

My fuses all look old so I'm wanting to replace them all.

A diagram would help with fuse amperage & what each fuse is for.
Unfortunately I don't have the owner's manual for the car!
