Cylinder OSPP-Classic reassembly
Information
•
Note the position of the parts as shown on the exploded view drawing on page 28
.
Danger of cuts on fingers etc.
The sealing bands, especially the inner sealing band has very sharp-edges. Wear gloves!
Preparations:
• Clean and dry sealing bands and cylinder profile, inside and out.
• Look out for damage, also at the edges of the inner sealing band.
Inserting the magnet strips (see diagram)
Cylinders with a diameter exceeding 40 mm the magnet strips may slip out of the cylinder profile.
If required, insert the magnet strips again as described below. The sealing
function can only be that the magnet strips are installed according to
specifications.
• Push one magnet strip in, leaving 5 cm sticking out
(it must lie on its narrow side).
• Place the second magnet strip on its narrow side above the first magnet
strip.
If the magnets repel each other:
• Push into the profile the second magnet strip without turning it over
(see diagram).
If the magnets attract each other:
• Turn the second magnet strip over i.e. 180° (about its longitudinal axis) and then push it in the profile.
Installing the piston
• Insert both slide shoes (28) into piston yoke (colour the same as old parts).
• Select the two support rings (25) (colour the same as old parts).
• Push two spacers (29), with magnet (30) between them, into one support ring (except on Ø 80, where
magnet system is installed inside piston).
• Push the two support rings on to piston (so that flat band guides are on top
- see diagram).
• Clip the two support rings together.
Check that piston moves smoothly, as follows:
• Insert piston into cylinder bore and slide it up and down.
• Replace slide shoe and/or support ring if:
- piston is too tight, or
- piston has too much play,
• Take piston out again.
• Insert cushioning seals (23) (so that seal lip shows on outside).
Greasing cylinder bore:
• Grease inside of cylinder bore as far as you can reach, use only the correct grease
(see spare parts chapter 14.1.1 Grease).
• Grease the two support rings and piston behind support rings.
• Slide piston up and down a few times (long cylinders, however, should be greased throughout).
• Take piston out again.
• Check that cylinder bore has a complete grease film, as follows:
- point cylinder at a light source and look through it,
no dry areas visible
,
- repeat greasing process if required.
