11. Use the bolt (removed in Step 4) to secure the bracket on the exhaust pipe (18) to the iL
system.
12. Continue at Section 6.5.2 to clean and refit the check-valve (17).
6.5.2
Clean and refit the check-valve (if fitted)
1.
Refer to Figure 6-3. Unscrew the two halves (2, 4) of the check-valve body (if necessary, use a
strap wrench, then remove the fluoroelastomer ball (3) and the 'O' ring (6).
2.
Use a cleaning solution suitable for the deposits to clean the valve body and the
fluoroelastomer ball. If necessary, replace the fluoroelastomer ball.
3.
Inspect the 'O' ring groove and the flange sealing-faces for damage; refinish if necessary.
4.
Position the 'O' ring in its groove in the valve body (4).
5.
Ensure that the fluoroelastomer ball (3) is correctly positioned in the valve body, then screw
the two halves of the valve body (2, 4) together.
6.
Refer to Figure 1-1 Use a new trapped 'O' ring (supplied in the check-valve servicing kit: see
Section 8.3) and the clamp (removed in Section 6.5.1) to secure the check-valve (17) to the
exhaust pipe (18). Ensure that the flow direction arrow on the check-valve (Figure 6-3,
item 7) points away from the exhaust pipe towards the exhaust-extraction system.
7.
Use a new NW40 trapped 'O' ring and the NW40 clamp (removed in Section 6.5.1) to secure
the check-valve outlet to the exhaust-extraction system.
