Assembly instruction

1. Application

These spare kits are usable for round barrel cylinders of series …/8000 (with cylinder sizes from 32 to 320 mm), for profile barrel cylinders of series .P../182000 (with cylinder sizes from 32 to 125 mm) and for round and profile barrel cylinders of series …./802000 (with cylinder sizes from 32 to 125 mm). 2. Disassembly of cylinder
– Loosen all tie rod nuts or tie rod screws on both sides of the cylinder and remove them as well as – if applicable – tie rods.
– Remove front end cover.
– Remove piston rod assemblyfrom the barrel.
– Separate barrel and rear end cover.

3. Part replacement

Disassemble all seals and – if applicable – the wear ring using suitable tools and taking care not to damage any sealing surfaces.
– Thoroughly clean all installation spaces for the seals and lightly grease them afterwards.
– Also all new seals have to be lightly greased.
– Fit new seals and wear ring taking care not to damage seals and sealing surfaces. If necessary, a proper assembly tool has to be used.

4. Assembly of cylinder

– Put a thin layer of grease on the inside surface of the barrel and on the piston rod.
– Fill the grease chamber behind the piston rod seal in the front end cover and put a thin layer of grease on the running surface of the piston.
– Fit the barrel to the rear end cover and rotate profile barrel into the desired orientation if applicable.
– Insert piston rod assembly into barrel taking care not to damage any seals.
– Slide front end cover carefully on piston rod in order not to damage the piston rod seal.
– If cylinder has tie rods, screw tie rod nuts onto the short threads of the tie rods and insert them
– Into an end cover. Put remaining tie rod nuts – if applicable – into second end cover. Tighten tie rod nuts crosswise to the specified torque.
– If cylinder has tie rod screws tighten them crosswise on both end covers to the specified torque.

Check cylinder for leakage (connection front end cover/rear end cover to barrel, piston rod seal)

5. Required grease:

Use only the grease from the grease package enclosed in this spare kit.
