1976 240D injection pump overflow tube
I have recently acquired a 1976 240D the 115 chassis style, and I opened the filler cap on the injection pump and discovered it was low on oil. I added about a pint, and later discovered about a half pint of oil on the garage floor.
Upon inspection I discovered the pump had a pipe fitting below the level of the filler cap with a short section of pipe turned down and the oil was dripping out of it. Is this an original drain or is this some modified addition? I thought the pump was supposed to be filled with oil up to the bottom of the filler cap bore. Does anyone know? Thanks. Michael P. |

Sounds like you just overfilled it. Others will verify.

IP pump
I too have a '76 W115 240D and I just changed the oil out in the ip last weekend for the first time. It is my understanding that some pumps have a small drain tube as you described, and some, like mine, have a banjo bolt on the lower side of the pump that you have to loosen which allows excess oil to drain out the side as you fill the pump with fresh oil from the top. The IP does not get filled to the top of the filler spout.

thanks Mike,
That makes sense. I guess I just overfilled it in an attempt to top off all fluids. It was running with no problems so just over did it I guess. |

You need to ask how to get the Old Oil Out?
Some have a drain Plug on others you need to suck the Old Oil out.
