Diesel Blocks
6725 Diesel Fixture
Small Diesel V Blocks
On these blocks it will be necessary to install the 6370Z, 10” parallels or 6794E, 8” parallels onto the bed
of the machine. These parallels are keyed, place them onto the deck surface and then push them toward
the rear of the machine. This will located them evenly on the middle keyway of the machine bed. Place
the two 6553F main bearing supports onto the parallels, these are also keyed and fit into the machined
slots on the parallels. This will put the two main bearing supports in line with each other. Tighten all bolts
to lock the parallels and main bearing support into place. Select the correct size main bearing locators
and install them into the mains of the block..
Note: Make sure there are no burrs or debris in the main bearing bores where they will contact
the main bearing locators. This can cause the block not to clamp properly and may cause tipping
or rocking of the block.
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.
Install the main bearing locators into the mains of the engine block. Lower the block so that the locators
go into the main bearing support.
The hoist must remain attached to the block until it is firmly clamped into
position. The blocks will have a tendency to tip forward until they are properly
supported and clamp. When not properly supported and attached to a hoist these blocks will roll forward
and out of the fixture. This will cause severe injury or death to operator.
Select the correct jacking screw to reach the block. Place the jacking screws into the jack bodies and
place on the parallels in a location they will support the block from rolling forward.
Position the block clamps so the front of the shoe will clamp the block in the middle on both ends. The
following illustration shows the correct triangle clamping system that should be used.
You can raise and lower the ends of the block by rotating the Hex nut located on the ends of the main
bearing locators.
