Does the injection pump on a 1987 300TD have a oil fill plug and a drain plug?

 

There is no Oil Drain Plug.

The Oil is supplied by from the Engine bay an Oil Pssage at the front of the Fuel Injection Pump and there is also a drain hole at the front of the Pump.

There may be an Oil Fill Plug like there is on earlier models; if there is one on your 87 that is only for use on a Fuel Injection Pump that all of the Oil has been drained out of to pre-lube it.
If there is no specific Oil Fill Plug you could use the Plug that you remove to hook up the RIV Timing Device and put Oil through that hole.

For others: On some of the Older Mercedes Fuel Injection Pumps that are not lubed by the Oil From the Engine the pump has its own Oil that needs to be checked and changed.

 

Thank You. I did see the one at the front of the pump; which I was thinking was the drain plug, because of where on the pump it is located; but I could not see anything which looked like a fill plug. Would you happen to know why there is a drain hole if the oil is supplied by the engine? Would this be to drain the oil in the pump when changing the engine oil or does the pump oil drain back into the engine oil pan when the car engine is shut off?

Found the answer to my questions.
What I thought to be a oil drain plug, for the injection pump, turned out to be a port for a special tool for holding the injection pump crankshaft in place when removing the injection pump and not a drain plug for draining the pump oil. Thanks Again to Diesel9112.
