4 Extract dowel 66-2 from the piston head using the appropriate sized screw threaded into the extractorhole.
5 Use the correct size spanner, remove piston head 66- 3 from rod 66-9 and remove ‘O’ ring 66-8.
6 Remove gland bearing and end cap 66-1 from piston rod and remove the ‘O’ ring 66-10, wiper seal 66-12 and rod seal 66-11. Check end cap bearing for damage, scores or nicks. If damaged, the bearing must be replaced as part of the end cap assembly.
