Pumps with a single mechanical seal: removing the pump housing
l Guide the optional special cylindrical tool (arrowed: TL-SP21-002-50,
TL-SP25-002-50, TL-SP40-002-50 or TL-SP50-002-50 - available to
order) over the shaft and push it home. This will give some protection
to the shaft splines as the pump housing is removed. It is important
not to damage the shaft while removing or installing the pump hous-
ing.
l Use a 17mm spanner to loosen and remove the two screws (right-
hand thread) and washers which secure the pump housing to the
power frame.
l If necessary, gently tap the pump housing with a soft hammer to free
it. Withdraw the pump housing carefully.
Note: the pump housing is heavy.
