Install the piston
Information
Piston seals have a sensitive sealing lip which should only be inserted into the cylinder barrel by pulling
action. For that reason the fitting sequence must be carried out as follows:
• Push on one piston seal (24) (so that groove of piston seal shows on outside).
• Grease piston seal and fill its groove with grease.
Risk of injury from contact with the sharp edge of the band!
Wear gloves:
• Place inner sealing band (17) on flat band guide (see diagram down) of one support ring
(so that „ground edge“ side lies on support ring).
• Push inner sealing band through piston without creasing it.
• Push the piston together with the inner sealing band into the cylinder bore, inserting the side without
piston sealing first.
• Push the piston into the cylinder barrel until it reaches a position of approx. 1-2 cm in front of the
piston seal.
• Put the pin into the centering hole of the inner sealing band, which is
located in the cylinder barrel. Push inner sealing band into the cylinder
until the other centering hole is flush with the end of the support ring.
• Insert piston.
When inserting the second support ring it is imperative to push down
the piston in order to avoid damaging the inner sealing band.
• Push the piston completely into the barrel and continue pushing with
the sealing band until the support ring emerges on the other side.
• Place the second piston seal onto the support ring with its groove show-
ing outside.
• Lubricate piston seal and fill its groove with grease.
• Put the pin into the centering hole of the inner sealing band, which is
located in the cylinder barrel. Push inner sealing band into the cylinder
until the other centering hole is flush with the end of the support ring.
Do not push centering hole of the inner sealing band beyond the piston
seal.
• Move the piston to the middle until one side of the inner sealing band is flush with the cylinder barrel.
• Remove excess grease from ends of cylinder barrel.
Torque moments for screws
The tightening torques for screws stated in the table below must be observed during the following assembly
sequence. This guarantees the safe function of the cylinder during operation.
