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. 9) 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 locked in place 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
hours.

Replacing the packing set:
REMOVAL:
1. Drain the oil out of the ram (if necessary use compressed air to move the
piston forward and back to force the oil out.
2. Run the piston into middle position. Unscrew the top (pos. 7) 30 mm. If
the top is sitting very tight, this can be remedied by heating the front of
the sleeve to approx. 300°C and then cooling it gently. Once the top has
been screwed out, pull the piston out towards the top, then screw the top
right off and remove the piston.
