Cleaning and Maintenance:
1. Abrasive can be removed by pushing brass plunger
in completely, (Figure 10) and lifting abrasive from
mandrel. (Figure 11).
Figure 10
2. Clean abrasive channel and abrasive using parts
cleaner and nylon brush. Reassemble and lightly
lubricate with your favorite light oil. Note: Arbor
assembly cannot be disassembled any farther than
abrasive removal. Damage will result.
TECH TIP: Hyper-Finish Diamond Break in procedure:
Like any diamond abrasive there is a break-in period. The
diamond, when new, may not be even from end to end
or side to side (this is normal with diamond abrasives).
This does not mean you will not be able to hone a straight
guide. While honing, you will need to stroke the hone the
full length of the abrasive.
There are a couple of ways you can speed up the break-in
process.
1. Use an old straight valve guide and run the hone through
the old guide several times, making sure you use liberal
amounts of honing oil. Keep in mind that you may hone
several hundred guides before the diamond abrasive
truly gets broken in and comes into its own. Once the
diamond is fully broken in you will notice it will hone
quicker and smoother.
2. You can take our Goodson Dressing Stick, (DS-CBN)
and manually dress the abrasive evenly. Soak the
dressing stick in DHO-10 or DHO-50 oil for several hours
before using. Make sure when dressing the abrasive,
you keep the crown on the abrasive, do not fl atten it out.
Once abrasive is even you will notice a shiny line the
length of the diamond.
This will ensure a long life for your diamond abrasive!
