1. Problem:I had to get a pulley off of my Power Steering pump and I couldn't use a jawed Pulley puller as that would just bend the pulley. I didnt have one of those clever pulley pullers.
Solution: I used the jawed pulley puller in one turn increments, and banged on the Puller Bolt each time after a turn of the bolt with a light hammer. The pulley came off in 5 minutes.

2.Problem: I had to put a "hard to get to" 12mm nut back on the underside of my Fuel Pump for my 87 300D. I could barely touch the location with my finger let alone use wrench.
Solution: I got a piece of 20" piano wire and bent the last 1/2" around the edge of the nut to hold it and then used super glue and a vise to really get a good hold. With the 20" reach of the wire I could easily position the nut properly. Then using the matching Bolt from the other side of the fuel pump, I was able to snag the nut and thread it into place...
