Thats the V-belt driven vacuum pump used on a couple of the gas powered models. Its a completely different pump than the engine mounted/driven one on the diesels. Attatched is the PDF.

Re: [MBZ] 115 Vacuum Pump Oiling
job# 704 titled "checking oil level in vacuum pump". I have never seen one of those belt-driven vacuum pumps. Ours are all cam-driven from the front of the injection pump. If you did have a belt-drive vacuum pump, of course it would need oiling. That page is for the 115.01X car, which is a gasser. Don't know why one of those would need a vacuum pump, unless it was a booster like my Falcon has. (For the windshield wipers.) -- Jim
Re: [MBZ] 115 Vacuum Pump Oiling
The pump has two bleeders, one to drain the oil and one to fill till overflow (fill verification). Not only do you have to fill the pump, you also have to change the oil in the pump by draining & then filling until some flows out of the second bleeder.

On my '72 220D, the vacuum pump never needed oiling. Replaced the diaphragm once, but that was it. Now the INJECTION pump is a different story. When doing an oil change, I had to remove the red Oel cap on the top of the pump, loosen the bleeder on the side next to the engine, and add oil until oil flowed out of the bleeder, displacing diesel.

The vacuum pump does not require oiling but the IP does!

Eric, I drove my 74 240D to 247,000 miles and never oiled the vacuum pump! You MUST be talking about the injection pump. When the 300D came out in 75, they used pressure oiling on the injection pumps. A small line off the block near the timing chain feeds oil to the injection pump via a small orifice. Excess oil continuously overflows back to the crankcase This carried over to 240D in 76.

Re: [MBZ] 115 Vacuum Pump Oiling
Im not sure what you are talking about really. This is the first time I have ever heard of such a thing. I dont see why it would need to be oiled.
