An earlier post (with the nice pics) has whet my appetite for my upcoming timing belt & tensioner/water pump/seal replacement job on the '89 240. (Before daughter goes to college in August). I purchased a crankshaft tool (I think this tool is used to hold the crankshaft stationary while the pulley bolt is removed) but I've got several other "tooling" questions:

1) Do I need to buy a special tool to "push in" the new cam seal? intermediate seal? crankshaft seal?

2) Do all three shafts (cam, intermediate, crankshaft) have threads on the inner portion of the shaft? What thread bolt do I need in order to use a special tool to "push" new seals into place?

3) Do I need a tool to "pick out" the old seals? (cam, intermediate, crankshaft)??

If someone has a list of things that I can buy from Home Depot that will allow me to fashion homemade seal tools, I would greatly appreciate having it. I absolutely cannot stand to get right in the middle of a job and not have the right tools.
Thanks,
