GHTS-Series Hone Heads
Sunnen GHTS-Series Two Stage Honing Tool uses
Sunnen GH Stone Sets and PHT Brush Sets.
Install GH-Series Hone Head by sliding Hone Head
Drive Tube into Machine Drive Tube; align Locating
Screw in Hone Head Drive Tube with one of the holes
in the Machine Drive Tube; then, tighten screw
(see
Figure 2-12)
.
NOTE: Hone head and expander plates are marked
with corresponding numbers. All numbered pieces
should be kept together when using this tooling.
IMPORTANT
Note reference mark on end of cone and on hone
body. These marks MUST be aligned to ensure cone
will be matched to expander plates. DO NOT deviate
from this orientation.
Install Expander Plates
Before installing stone/brush sets, check to make
sure expander plates are in their correct locations
(see Figure 2-13). Each plate is marked with a
number and a letter, which corresponds to mating slot
on hone body. Expander plates are angle cut; plates
must be installed to match angles of inner cone.
Install Stone/Brush Sets
Always install stones/brushes in as sets. To install,
proceed as follows:
1. Verify hone head is fully retracted. Both sets of
expander plates should be flush against the hone
body once inserted into their correct numbered slot.
2. It is easiest to put grouping of stone/brush sets
into head at a time, working in a counterclockwise
direction, looking down from universal joint
(see
Figure 2-14)
.
• Grab spring on bottom of hone head, in between
mounting clips, and pull it over spring slots in
bottom of stone/brush set, using GH-50 Thumb
Spring Tool
(refer to Figure 2-14). Repeat for
second set.
• Then, go to top of hone head and pull springs over
spring slots in top of stone/brush sets.
3. Proceed to next stone/brush sets and
repeat step 2
until hone head is loaded with all stone/brush sets.
4. Once all stone/brush sets are loaded in head,
expand and retract sets in head several times to
ensure all moving parts are seated in head properly.
Remove Stone/Brush Sets
When removing stone/brush sets, always remove in
sets. To remove and/or replace stone/brush sets,
proceed as follows
(refer to Figure 2-14):
1. Grab spring on bottom of hone head, in between
mounted clips and pull it down and away from
spring slots in bottom of stone/brush set, using GH-50
Thumb Spring Tool. Repeat for second set.
2. Then, go to top of hone head and pull springs off
spring slots in top of same two stone/brush sets.
3. Pull stone/brush sets out of hone head making
sure expander plates stay in hone head.
4. Fill empty slots in hone head with new
stone/brush sets, and reattach springs.
5. Proceed to next two stone/brush sets and repeat
steps.
Truing Stones
Sunnen diamond abrasive honing stones have been
pre-ground to a radius and can be used directly from
the box. Bore geometry should be monitored as the
stones true in.
