Operating Instructions
The purpose of this chapter is to explain and then guide the operator from loading a block through running
an automatic cycle.
All modes of operation will be discussed in this chapter.
Note: We recommend, particularly for operators unfamiliar with the boring machine, to practice
on a junk block in order to become familiar with the controls and procedures of the boring
machine.
Loading Blocks
Small Gas and Diesel
Manual V6/V8 Combination Fixture 502-1-72H
Handle the block and fixture with EXTREME care and guidance. A block hoist
is REQUIRED. Mishandling of a heavy engine block and fixture may result in
the dropping of parts and personal injury.
The Model 502-1-72H manual V6/V8 combination fixture is a fast, simple and universal system to properly
and accurately hold most 60 degree V-type engine blocks for either cylinder boring or deck surfacing.
See illustration on the following page.
Boring Application
NOTE: The block must have the main bearing caps in place and torqued.
Care must be taken to assure the contact edges of the locator bar are near the cap split line. A pair of 3/8”
and 1/2” spacers are provided for blocks with large main bearing bores, to enable the bar to locate near
the main bearing split line. (See figure 2)
V-blocks: (blocks with main bearing center lines no more than 1/2” higher than the pan rail plane) are
mounted with the 502-3-8B V-block frame in place. Select the 90-degree option placement of the frame
to suit block length, or main bearing caps will interfere with frame. Rotate frame 90 degrees by moving its
shoulder screws to alternate set of holes.
Y-Blocks: (blocks with main bearing center lines 2-3/8” to 3-1/2” higher than the pan rail plane) are
mounted directly on the fixture. Some Y-blocks (GM 60 degree) have too narrow pan rails and some have
too low main bearing location which will require the use of the 502-1-15C precision 1-1/4” x 3” parallel set
to raise and or support the block. Use the shoulder screw from the V-block frame and hook the parallels
over the back of the V-fixture.
This fixture may be easily repositioned on the support parallels (without a block in place) to shift from the
60 degree support surface to the 90 degree support surface or vice versa.
