CF-500 Instructions
After assembly, place the CF-500 Manual valve spring
bench on a solid flat work table, and follow the next
operation instructions:
1. Place the cylinder head on the side supports
protected by a plastic cover (fig. 1)
2. Manually adjust the side supports, tilting the cylinder
head to the correct working angle, and lock them in
position (fig. 1)
3. Use the dowel pins located at the brace plates, in the
front square tube, to keep the cylinder head from
sliding out of the working area, and keep it in correct
alignment (fig. 1).
4. Now place the pressure foot on top of the valve-
retainer assembly, making sure it’s perfectly
centered. Make additional adjustments, if needed.
5. Apply pressure on top of the valve assembly until the
support post located at the bottom of the “C” frame
touches the valve head.
6. Now is the time to push the valve assembly all the
way down until the valve keeper locks are released.
If the keepers are too tight, the use of the slider
hammer on top of the main shaft will help. Just one
or two strokes will release them easily. (fig. 2)
NOTE:
At this point, the use of tweezers and magnets
will facilitate the retrieving of keeper locks and
retainers. Check our catalog for a wide selection of
these tools (fig. 3)
7. Once you calculate the depth of the first valve
assembly, mark the position with the lock ring
located at the upper part of the main shaft, and
proceed with the disassembly of the rest of the
cylinder head.
8. To assemble, simply reverse the steps of these
instructions. Always replace the valve stem seals,
and make sure you check our catalog for some
keeper assembly tools.
9. For cylinder heads with canted valves (sideways
tilted angle) follow this procedure: Loose the locking
knob located in the back right side of the “C” frame,
and tilt it sideways until reaching the right angle.
Place the pressure foot on top of the valve-retainer
assembly, and make proper adjustments. Then lock
the frame in position with the knob, and proceed with
the disassembly / assembly operation (fig. 4)
