b.
c.
Do not use glass or metal tools to scrape
dirt or locking compound from pump
housing surfaces. Scraping with metal or
glass will destroy the thin, protective coat-
ing on the housing. This could lead to
leaks or early failure of the pump.
Remove all residue from mounting flange seal sur-
face A. Use plastic scraper, if needed, to scrape
away residue. Do not use glass or metal scrapers
on seal surfaces. Scraping with metal or glass will
destroy the thin, protective coating on housing.
Make sure all preformed packing grooves are
clean. If necessary use a wooden or plastic scraper
to clean grooves.
2. INSPECTION AND REPAIR OF HOUSING
a.
b.
NOTE
Inspection of the pump housing in this task is limited to the mount-
ing flange and cartridge bore. Also covered is the inspection of the
inlet screen. For inspection of all other items refer to the individual
tasks.
Visually inspect all surfaces of pump housing for cracks. If any cracks are found, replace pump housing mount-
ing flange.
Visually inspect mounting flange seal surface A for scratches, nicks, or burrs. Run your finger lightly over any
defects; if sharp edges are felt they must be removed. Polish off sharp edges of scratches, nicks, and burrs using
500 or 600 grit, wet or dry, emery paper. Moisten emery paper with water.
