Here is a quote from an old post I have concerning the problem you are refurring to.

"It turns out that a number of IPs made in 1982 were mismarked, so that you actually have to set the driven element so that the wide mark is 3 splines PAST the timing mark. If you've done this, the pump works like any other. This information is clearly set forth in the OM617 engine manual, proving yet again that, even if you know how to do a job, RTFM first."
