Hey Guys, The Mack/Scania Diesel in our B60 has a Manually Filled Lubricated injector pump. According to my service manual, this means that I should fill it with new motor oil every 1600 miles. The problem I'm faceing is that in the service manual, it says "see operation manual for filling procedure" I do not have the Operation Manual, I only have the Service Manual. I need to know where to put the oil, how much, and what grade to put in. If anyone knows anything about this, I would like to hear it, as it is crucial to the life and performance of the engine. This is the pump: Here's the idenifacation plate: It says it is a NNR6H80/273 which is actually not in the list in the manual. The smallest (numericly) is a NNR6H80/316, but that one seems pretty simalar to the one on the truck. Other ones in the book are ...90/360 and ...90/408 Etc. If anybody could share some thoughts about this, that would be great too. Thanks, Ben
