6.2 How to clean or replace the strainer screen:
Note:
On older models the strainer was a 0.8 mm perforated screen. Newer models use a 100 mesh screen
to provide improved screening. The screens are interchangeable.
Screwed and socket weld connections (Figure 7)
-
Access to the strainer screen can be obtained by removing strainer cap (
3
).
-
Remove the strainer screen (
4
).
-
Fit a new or cleaned strainer screen into the recess in the cap (
3
).
-
A new gasket (
12
) should be fitted and the cap (
3
) screwed into the body and tightened to the
recommended torque (see Table 1).
Note:
The use of a thread lubricant is recommended.
Flanged connections (Figure 8)
-
Unscrew the four bottom cover nuts (
9
) and remove the bottom cover (
3
).
-
Remove the strainer screen (
4
) and inspect. Locate the new screen or replace a cleaned screen onto
the spigot on the bottom cover (
3
).
-
Reassemble the cover (
3
) to the body using a new gasket (
10
) ensuring that the gasket faces are
perfectly clean.
-
The cover nuts (
9
) should be tightened to the recommended torque in a diagonally opposite sequence
(see Table 1). After 24 hours in service the cover nuts should be checked for tightness.
Note:
The use of a thread lubricant is recommended.
6.3 How to replace the cover studs:
Screwed and socket weld connections (Figure 7)
After removing old cover studs (
8
), fit new cover studs until the studs bottom out.
Note:
The use of a thread lubricant is recommended.
Flanged connections (Figure 8)
The flanged TD62M and TD62LM are fitted with two different lengths of studs. It is therefore important
that the correct length of stud is fitted into the correct tapped holes in the body. The studs are packed in
separate labelled bags (A, B, C, D), within the spares pack. The stud holes are as marked on the diagrams
in Figure 11. Fit new studs to the recommended torque (see Table 1) until they bottom out.
Note:
The use of a thread lubricant is recommended.
