Feed Pipe Assembly
If fluid leaks occur from the pipelines on the spray boom, it is necessary to check the sealing. It is necessary to disassemble
the pipe fitting to locate the O-ring/gasket.
Recommendation is occasional maintenance of the O-rings/gaskets and pipe assemblies.
Usually is poor sealing caused by:
•
Missing O-ring or gasket.
•
Damaged or incorrectly seated O-rings.
•
Dry or deformed O-rings or gaskets.
•
Foreign objects.
In Case of Leaks
DO NOT overtighten the union nut. Instead, disassemble the pipe fitting and check condition of the O-ring/gasket. Replace,
if damaged or cracked.
Fitting Types
There are two sizes of boom pipes in use, Ø22 mm and Ø25 mm. They share the same union nut, t-pieces, etc. However, they
differ in the following components:
W.
Gasket for 22 mm pipes (part no. 24266200).
X.
O-ring for 25 mm pipes (part no. 24263000).
Y.
Lock ring Ø22 mm (part no. 33523300).
Z.
Lock ring Ø25 mm (part no. 33515500).
