6405F Large V-Block
Place the 6405 supports on the machine bed. Make sure there is no debris or burrs on the mating
surfaced. The supports should be placed on the machine bed with the two dowels on the bottom of the
supports into the middle keyway. Place the supports the same distance apart as the mains you will be
using. On long blocks, it is recommended to use main bearing locations inward from the ends, to more
equally balance the block and avoid sag. Push the supports back toward the rear of the machine against
the dowel pins. This will line the supports up with each other. Tighten the four (4) mounting bolts on each
support.
Install the correct size locators into the main bores that will be used.
Handle these large blocks with Extreme care and guidance. A block hoist is
required when handling these blocks. These blocks should be lifted from the
block bank surface.
The hoist must remain attached to the block until it is firmly clamped into
position. The blocks will have a tendency to tip until they are properly
supported and clamp. When not properly supported and attached to a hoist these blocks will roll forward
or backwards and out of the fixture. This will cause severe injury or death to operator.
The main bearing bores being used, should be on centerline of each support. Set the jacking bodies, with
the proper length jack screw installed onto the machine base. These should be located in the general
area of the supports. Temporarily secure to the deck with at least one bolt.
Lower the block down onto the supports. Place a level on the deck of the engine block and check the
level front to back. Position the jack stands in a location to properly support the block and secure. To
level, use the jacking screws to raise or lower the front of the engine block.
Position the block clamps on the machine bed and secure in a location to allow proper clamping.
The following illustration shows the correct triangle clamping system that should be used.
