Suggested Standard Shop Practices
The following are suggested standard shop practices
• Use a clean workbench in a dust and dirt free work environment. Do not create
air-borne dust.
• Use lint-free material for wipe cloths. Do not use paper towels.
• When blowing off parts with compressed air, use only clean dry air. When flushing
parts with a solvent, use only clean filtered fluid.
• Protect all machined and lapped mating surfaces against nicks, scratches and burrs.
• Before assembling, make sure that all parts are clean, free
of
metal particles, dirt,
dust, etc.
• Use extreme care when aligning close tolerance machine parts for assembly. Do not
force parts together.
If
mating parts bind, then separate them and try again until
properly aligned.
Caution:
It should never be necessary to force an assembly together.
• Plungers are made using strong but brittle material. Avoid dropping, sharp blows or
heavy loads when working with these expensive parts.
• Inspect threaded areas
of
components that are removed for service.
If
damaged, then
repair the threads or replace the component before final assembly.
• Inspect all surfaces (especially polished surfaces) for cracks, pits, unusual marks,
surface wear or rubbing. Repair or replace all questionable parts.
• Always use Teflon™ tape to wrap threaded ends
of
components before assembly.
• Notify NLB Customer Service Department for all repair requirements which cannot be
handled locally.
