TO REPLACE UPSTEAM SPREADER IN HEAD
A. Insert 5/16” Allen wrench (8) into hex
opening in spreader (9). Hit wrench
with hammer (two or more very firm
hits) to break corrosion bond between
threads of brass spreader and
aluminum head. Unscrew spreader (9)
counter-clockwise and remove with old
gasket (10). Hold upsteam tube (7) at
the same time to prevent damage.
NOTE:
After removing old gasket,
scrape and clean gasket seat
in head with a small flat
scraper before installing new
gasket and spreader.
B. Using pipe dope on all threads, screw in
spreader and gasket being sure that
the upsteam tube enters the opening in
the spreader as the spreader comes
down into the head. Tighten the
spreader securely with an Allen
wrench.
NOTE:
It may be necessary to
remove the upsteam tube to
replace spreader.
C. Turn on steam supply and check for
leaks.
D. After installing new steam spreader,
file or grind extended part to match
contour of the head. On polished
heads, use “fine” emory cloth to remove
sharp burrs and file marks. Polish if
desired.
