Figure 8-7: High Pressure Cylinder Assembly Removal and Installation
NOTE
If thread or metal surface galling is detected during removal, galled surfaces and
threads must be filed, sanded and lubricated prior to reassembly. See the
procedure, High Pressure Cylinder Maintenance.
High Pressure Cylinder Assembly Installation
1. Verify that the high pressure cylinder threads and alignment surfaces are adequately
cleaned and lubricated with Pure Goop, and that the threads have been sanded and dressed
if galling was encountered during removal.
2. Verify that the high pressure seal assembly and cylinder liner are correctly installed.
Align the cylinder assembly with the plunger and the hydraulic cylinder head, using the
cradle tool to support the weight. Carefully push and lift the assembly into position until
the threads are ready to engage.
3. Thread the cylinder assembly into the hydraulic cylinder head.
