SERVICE/TECHNICAL INFORMATION
No. 290 - 27/06/00- KEH/RiL
Subject: Delta Booster HP-hoses (pump)
Problem:
Leaky between jacket and hose (in some cases the hose is pressed off).
Cause:
To gain tightness at the locking ring it was necessary to tighten very
strongly, which caused a torsion between hose and jacket.
Solution:
A new type hoses are introduced, which instead of the locking ring are
mounted with an O-ring, and a new type of fitting, which only needs an
easy tightening to gain 100% tightness.
Period:
The hose is mounted on all Delta-Boosters produced after 15.08.98.
Action:
Replacement is only to be done, if a leak is found.
Spare part:
Spare part no.: 7302031 has not been changed, since the new hose is
100% compatible with the old hoses.
