It is important to ensure that the shaft cannot rotate while the shaft nut is fitted. It
may conveniently be secured using a tommy bar or a spanner handle between the
spider castellations on the drive shaft. Alternatively, a well-padded wrench can be
used on the shaft and the key or keyway. A blocking tool for the shaft is optionally
available for easy opening of the locking screw (SPS 200: TL-SP20-010-31).
Fitting the shaft nut
l Check that the shaft nut O-ring (arrowed) is in position on the shaft nut.

spanner supplied with the pump. Tighten it to 65Nm.
