Fuel injection pump oil

Could anyone please tell me what type of oil to put in a diesel fuel injection pump on a Leyland 4/98?

The service manual calls for an oil change every 200 hours and im going to assume this hasn't happened.

Is it just a question of draining out the old oil, tightening the drain plug and then pouring oil in until it comes out if the level plug?

Thank you in advance.

Think I used the same oil as in the engine, similar on Fords with inline pump.

That's spot on Pete, and the procedure is exactly as Chris has stated. :thumbup:

Also the 4/98 was fitted with two injection pump types over the years, the CAV dpa rotary type or the Simms inline pump.
Only the earlier Simms has a separate oiling system to top off/change, the CAV type is self oiled by diesel throughout.
