The Drive end of the Fuel Injection Pump has what I don't know if you could call a gear but there is a short cylinder that has a lot of fine splines on it. On the Cylinder is a spot were 2 splines are gone and that lines up with a Mark on the bearing Cap on the front of the Fuel Injection Pump.
That drive end slides into a floating Collar. That means that the Timing/Timer has nothing to get messed up when you remove the Fuel Injection Pump.
If the Stuck the Pump in with the Splined Cylider is lined up properly when it was stuck in when they stuck the Fuel Injection Pump back in they simply did not center the Kidney Slots on the Fuel Injection Pump on the 3 Studs that are on the Block. If they are not centerd.
