The spring system cover is under heavy pressure. It must be carefully
removed and installed using either the hydraulic press, the threaded
rod, or the spring box tool method. If the spring system cover is
removed incorrectly, the springs can eject with enough force to cause
serious injury or death!
Hydraulic Press Removal Method
5.3.1 Remove the ramming shoe per section Ramming Shoe. Separate the
ramming system from the upper machinery per section Bellows.
5.3.2 Remove all but two of the socket head cap screws that hold the spring
system cover to the spring cylinder.
5.3.3 Place the spring cylinder in a hydraulic press and position the head of
the press in firm contact with the spring system cover.
5.3.4 Lock the press and remove the remaining two screws.
5.3.5 Slowly release the press and allow the springs to expand.
5.3.6 After all the spring pressure is released, remove the spring system
cover, the gasket, and the bottom spring set.
Hydraulic Press Installation Method
5.3.7 Install the bottom spring set into the spring cylinder.
5.3.8 Place a new gasket onto the spring cylinder.
5.3.9 Center the spring cylinder, the springs, and the spring system cover
under the hydraulic press ram.
5.3.10 Align the holes in the spring system cover as close as possible with the
holes in the spring cylinder; dowels or steel rods can be placed in the
holes to act as guides.
5.3.11 Compress the springs until the spring system cover rests on the spring
cylinder.

screws to 24 Nm (18 ft.lbs.).
