Once both parallels are installed on the machine bed, place a magnetic indicator on the spindle towards
the main bed. Indicate the adjustable parallel into the stationary parallel to within .002” on the In/Out and
height. This lines the fixture up close so the block can be loaded and then use minor adjustments on the
fixture to line the block up.
Select the set of V cradles for the block you are going to be machining. There are various types of cradles
that can be used on this fixture. There are risers available also that can be mounted to the cradles to
accommodate certain blocks. For cradle and riser selection refer to the Options section of this manual.
The CAT 3500 series cradle is shown in this example.
Place the cradles on the parallel. Line up the horizontal key on the cradles with the key slot on the
parallels. Generally, the rearward key slot is used, but on large blocks such as the CAT 3500, it is
necessary to use the front key slot to allow clearance between the machine column, and engine block.
Install mounting bolts and lock the cradles down. Due to the extreme weight of these blocks, clamping is
usually not required. Threaded rods and clamp bars bridged across the cylinder bore, and threaded into
the cradles is a way to secure the block if desired.
For in-line blocks, cradles are not used. In this case, round locators are bolted directly to the parallels.
Lower the block with the end cylinders over the locators and push the block towards the front or rear. This
will position the block in a straight line with the machine travel. Secure with threaded rods and clamp bars
bridged across the cylinder bore, and threaded into the locators.
