ECi's Enhanced Piston Skirt Coating
for FAA-PMA 520/550 Continental
Replacement Pistons
 San
Antonio, TX, June 21, 2004 -
Engine Components, Inc. (ECi) complements their TITAN® product
line by enhancing their new FAA-PMA 520/550
TCM replacement pistons. While it is common industry
practice to apply an anti-scuff coating on the piston
skirt of 520/550 pistons to prevent scuffing during break-in,
promote ring seating and long cylinder life, ECi exceeds
industry standards by adding an engine type identification
marking into the skirt coating. The coating rubs off
from the piston after the initial start-up/break-in/run-in
period without any detrimental effects on any other engine
component while at the same time does not clog the oil
filter. The modified anti-scuff coating will assist the
engine overhaul mechanic, enhance the quality of engine
overhauls and improve safety.
Enhancements from ECi:
- A. By carefully masking the area on the skirt
that is to be coated, the eligible engine series appears
as silver letters against the black coating. This enhancement
provides the mechanic assurance and verification for
proper engine model number installation. Pistons installed
in ECi Cylinder Assemblies need only be removed from
the cylinder bore far enough to facilitate piston pin
installation as the rings have been installed in accordance
with ECi's Service Instruction 94-4-1, ECi Piston Ring
Sets Applications, Fitting Instructions and Reference.
- B. A small area on the base of the skirt
is left uncoated so that accurate readings of the major
diameter of the piston can be made without influence
from the coating thickness. This measurement ensures
proper skirt-to-cylinder bore clearance.
- C. While all certified pistons are marked
in accordance with regulatory requirements, low compression
pistons and high compression pistons are easily misidentified
and installed in ineligible engines. High compression
pistons in a turbocharged engine could create a severe
safety problem. With ECi's engine type identification
marking, verifying the proper engine model number is
assured.
