T&T: Eberspacher D7L dismantling help needed

[Gale Plummer]

Yes, the red fan is held to the motor shaft by a C-clip.  Under the fan is pin
in the shaft that fits into slot on the rear of the fan.   The pin does not
need to come out.  The motor and fan assembly comes  apart by removing the (3
I think) bolts.  Slinger and fan are connected by a nylon/rubber drive
coupling that comes apart when you remove the motor from the housing.  Under
the drive coupling is metric headed shaft end with a bit of a rounded
section.  Hold the slinger and gently unscrew this nut.  The slinger with then
come free.  Take care to record the stack order for the bearing and shims that
will be free when the slinger is removed.  

Cleaning the slinger is key to
easy lighting....  The trick lies in the internal edges of the slinger........

Hi list

A
little progress. The burner and heat exchanger have been successfully
parted
(at the expense of the gasket), but I'm at a standstill again! At
present, the
burner, fan, fan motor etc are still one unit. Do I need to
remove the fan and
motor to release the items on the shaft in the burner or
is there some way to
remove the fuel slinger (atomizer) that's presently
preventing the burner end
plate from being removed? The small amount of
shaft protruding from the fan
has a groove around the circumference that
looks as though it held a circlip
although there is no sign of one left. The
shaft passes through a hex shaped
metal insert in the plastic fan but
doesn't seem to unscrew, although the
amount of force that can be applied to
try this is limited by the plastic
nature of the fan. Gale pointed out the
fragility
of the coupling (there's
quite a bit of backlash between
the fuel slinger at one end and the fan at the
other) so you can understand
that I'm rather reluctant to proceed without
confirmation of what I need to
do next!
