Fastening the end stud (2005):
Screw the hex nuts C (3020) down into the thru bolts
(3010) as far as possible.

(2035), the second washers (3070), the end stud
(2005) and tighten with spring washers (3015) and
hex nuts A (3020).
Finally, fasten the support foot (2035) from behind
with the two hex nuts C (3020).
When tightening hex nuts (2030) a gap will remain between

Ensure during refitting that the O-ring (8015) or, where a heating jacket
(3025) is installed, the O-rings (8030) are in perfect condition and will sit
correctly.
Ensure that the drain plug (2015) is not screwed too tightly into the pump
housing (2010), since otherwise its conical thread may break the pump
housing (2010).
The torque should be about 40 - 50 Nm.
