Dismantling And Assembly - jcb JS300 Service Manual

Dismantling the Piston Rod from the
Cylinder Tube
Refer to Section 1, Service Tools.
Before starting work, clean all surfaces with a suitable
solvent and dry with compressed air.
Each part is precision made, so handle with care. Do not
force any part as this may cause damage.
Protect the dismantled parts if they are to be left for a
period of time.
1 Drain the oil.
2 Disconnect the external piping.
3 Secure the ram.
Note: Fix the ram in a vertical or horizontal position. The
vertical position is more favourable for dismantling/re-
assembly work. Use the bottom pin hole for preventing the
ram from turning on its axis and for fixing the ram in the
axial position.
Remove the cylinder head cap screws (14 off) with an
Allen wrench. Use an extension pipe such as shown in the
figure below to facilitate bolt loosening.
