Some body had posted a while back how to time a 7.3 when the timing gear for the injection pump has been removed. You line up No. one cylinded on TDC and then put some marks on the timing gear aand set it in. It has worked slick the 3 or 4 times I have done it. I thought I had saved it on my computer and also had a copy in the shop, can't find any of them.
