I've measured the timing chain stretch and ordered the correct woodruff key. While I wait for it to arrive (special order) I was going to set the pump timing. The way I see it the crank turns which pulls on the timing chain on the driver's side around the injection pump and the vacuum pump (and in my case the hydraulic pump for SLS) then up and over the cam, then past the tensioner and back to the crank. Because the tensioner is after the cam, and the injection pump is before the cam, I should be able to set the injection pump timing before the new woodruff key arrives. It will be one less thing to do once the key arrives.
