.....
The caps are not all that tight a fit in the block, something called a
locational clearance fit. To get them out you screw a bolt in one of the
taped holes and pull with a gentle taping of a slide hammer (aka "dent
puller"). The threade in the front and rear bearing caps are for oil pan
bolts, so 1/4-28 UNF (or SAE fine thread). The one large threaded hole
in the center bearing cap is (if memory serves me well) 7/16-20 UNF
(ditto SAE fine thread). You can get these bolts at a hardware or auto
parts store.
The cheapo dent puller variety slide hammer is available from J.C.Whitney
for $16.99. The more complete slide hammer and puller kit is 49.99 and
comes with 2-jaw and 3-jaw inside and outside pullers (good for small
gears and oil seals), an axel puller adapter, body sheet metal screw
puller, body puller hook, and locking plier adapter. A very handy tool
to have around (once or twice a year). For a little more money you can
pick these tools up at your local auto parts store.
And if you have some time on your hands and feel a little creative, you
can build your own slide hammer from a threaded rod, a few hex nuts and
flat washers, and a piece of pipe that will slide over the rod. Adapting
the end of the rod to the part to be pulled is the creative bit.
