Masking of fuel and lube oil pipe con-
nections (for classified engines only)
The unions of pressurised oil and fuel pipes are
masked with a protective tape.
If this tape is removed during a repair, the unions
must be masked with protective tape again after-
wards.
The following pipes are affected:
− Oil supply pipe to turbochargers
− Fuel pipes between supply pump, filter and
injection pump
− Injection pipes protected against leaks
Fig. 1
A protective tape is wound around the unions. En-
sure that there is 50 % overlap on every pass.
Figs. 2 − 4
The unions to be masked must be clean and free
of oil and grease.
Do not apply the protective tape unless this is the
case
