I have been trying for over a month now to pick up a decent service manual on Ebay. I just bought my third stinker.

I am tearing down a 84 300sd motor to recondition and wondered while I continue to wait for a service manual, if I could get some help here so I can continue.

Removing the Injector pump from the block - Is there anything I need to know here? Parts to mark position for when reassembled? Anything going to fall out at me?

Disassembling the timing chain - Again is there a procedure I should be following?

Removing the Harmonic Balancer - Anything to beware of?

Like I said, a good service manual would cover all these issues. Thanks for any help.
