Required Tools
Upon assembly and disassembly of the actuator there are
basic tools required. The tools and their intended func-
tions are as follows:
1. Flashlight - helps examine timing marks, component
failure and overall condition.
2. Felt Marker - match mark the timing marks and out-
line troubled areas.
3. Allen wrench - removal of port plugs and set screws.
4. Box knife - removal of seals.
5. Seal tool - assembly and disassembly of seals and
wear guides.
6. Pry bar - removal of end cap and manual rotation of
shaft.
7. Rubber mallet- removal and installation of shaft and
piston sleeve assembly.
8. Nylon drift - installation of piston sleeve
9. End cap dowel pins - removal and installation of end
cap (sold with Helac seal kit).
The seal tool is merely a customized standard flat head
screwdriver. To make this tool you will need to heat the flat
end with a torch. Secure the heated end of the screwdriver
in a vice and physically bend the heated end to a slight
radius. Once the radius is achieved round off all sharp
edges of the heated end by using a grinder. There may be
some slight modifications for your own personal prefer-
ence.
