Dismantling and Assembly
When Assembling
15 Turn the inlet/rotor casing onto its side. Working inside
the bell housing clean the female shaft and coupling
spacer (Fig. 2 (8)) with JCB Super Clean Solvent. Use
JCB Lock & Seal to make a seal between shaft and
spacer by applying a complete run around the shaft
about 20 mm from the bearing. Assemble the spacer
and rotate a full circle to ensure a complete seal of
sealant. Place the clamp (tool 10) on the shaft with M12
x 45 screw and torque to 100 Nm (74 Ibf/ft).
16 Assemble oil seals (1 & 5) into the oil seal housing (3)
using service tool (tool 15). Pack between the seals
with JCB HP Grease. Fit back-up washer (6). Finally fit
oil seal (7) using service tool (tool 16). Lightly oil the O/D
of the coupling spacer and clamp. Using a new joint,
slide the oil seal housing into the inlet/rotor casing.
Note: The capscrew holes in housing and joint are off-set to
ensure correct positioning of the relief relative to oil port (13).
Secure with 4 (long) M6 capscrews coated with JCB
Lock & Seal and torque to 11 Nm (8 Ibf/ft). Remove the
clamp.
17 Using a new joint, refit the bearing cover over the male
inlet bearing. These capscrew holes are off-set also.
Use JCB Lock & Seal and replace the four capscrews,
torque tighten to 11 Nm (8 Ibf/ft).
18 Check all plugs and fittings are replaced. Refit the
delivery mounting foot, inlet adaptor and unloader.
Replace the compressor unit in the machine.
