Normal Operating Procedure
The normal operation procedure on smaller V-blocks is to first pick up the block. Place the 502-1-82X
locator bar through the main bearings and hoist the block into the fixture. Pulling the block towards you,
with the locator against the positioners, will prevent jamming in the slot of the guides during the loading
and unloading operations. The locator bar is positioned with the word ‘UP’ that is on the end of the bar
facing up and away from the operator. (see figure 1) After the locator bar is engaged in the positioners,
pivot block outwards as you lower it. Slide block to the far left (this is the non adjustable position).
Make sure the block is firmly seated in place and not resting on pan-rail burrs or other interference
points. Accurate seating can also be a problem with extremely warped, distorted blocks. Another cause
of problems is failure to remove main bearing inserts. The locator bar has a relief for blocks with a small
main bearing or seal. Rotate locator bar clamps into position & lightly tighten the hand screws, applying
even pressure to both. Clamp the block securely with the main base clamp arms.
Warped or distorted blocks may require leveling of the deck surface in the long direction. This is possible
with the hand-screw assembly in the left-hand bar positioner. Loosen both clamp hand-screws and slide
the locator bar to the far right position. Retighten both clamp hand-screws. Raise or lower the adjusting
hand-screw as required. For the non-adjustable position slide locator bar to the far left.
