Replacing the hydraulic sealings:
REMOVAL:
1. Empty the oil from the ram, compressed air can be used to move the
piston rod back and forth, to press the oil out.
2. Place the piston rod in the middle position.Unscrew the gland (pos. 3)
30 mm out. If the gland can't be unscrewed, it may be necessary to warm it
up to 300°c. Let it cool off slowly. With the gland screwed out, pull the
piston rod out towards the gland. Screw the gland all the way off, and the
piston rod can now be removed.
3. Remove the self-locking nut (pos. 10).
4. Remove the sleeve (pos. 4).
5. Pull the gland off the piston rod (pos. 2).
6. The sealings above the sleeve are now removed, (pos. 5,6,7,8,9), use
either a awl or a screwdriver.
7. Clean all the parts. Check for filings and shavings, make sure that their is
no rust in the gland. If this is the case, it must be romoved.
ASSEMBLING:
1. Assembel the new sealings in the gland and sleeve. The scraper ring pos.
5 is mounted with the help of a pipe, that fits around the outside of the lip.
The sleeve (pos. 98) is mounted with a round iron bar or screwdriver
2. The threads on the gland and ram housing should be greesed before assem-
bling, (rust protection).
3. The gland pos. 3 is now mounted over the piston rod.
4. The sleeve pos. 4 is mounted and the self-locking nut pos. 10 is screwed on
with "loctite". Make sure that the threads are clean, no oil or greese.
With use of loctitte, you must not fill the ram with oil the first 12
