Nasty bit, Needle Roller Bearings in place after about
10 years of fiddling. This is the inner bearing holder
(nearest the compressor wheel).
|
|
With a piece of
card to hold the bearings in place, I had to carefully
slide the rollers in to place and then take the card out
at the last second. |
| |
|
|
This is the second
and upper part of the bearing support housing and was
fairly straight forward to assemble. The lock nut and
securing rings have yet to be tensioned.
|
|
From this picture
you can see the drive gear that will power the accessories,
straight from the main spindle. |
|
|
|
| To save time,
and because putting this back is a bit fiddly, I have
used some drinking straw sections to aid reassemble of
the combustion chamber. There are five dual nut tabs that
sit behind the holes shown in the image, the idea being
to slide the straws through the bolt holes and in to the
nuts and then the other end of the straw in to the bolt
holes in the gearbox, then carefully mount them together.
|
|
Jobs a goodun,
combuster now in place and straws taken out one at a time
and then replaced with the securing bolts. To finish this
part I will Lock Wire the bolt pairs together. |
|
|
|
And this part of
the reassembly looks like this.
|
|
The Oil pump
has now been mounted with the scavenge pipe seen
nearest to us, I presume the quick release connectors
fit directly
to the Harriers main oil tanks.
|
|
|
|
This
is the fuel pump, I know piping this is going to be a
headache because I'm
doing all of this with out any form of reference manual,
and
working out a way of bypassing the governor that normally
would have been fitted on the Power Turbine section is
going to be troublesome, unfortunately this may even
stop the project in its
tracks.

Top view of the
assembly so far, with the small oil sump at the bottom
and the gearbox spanning
out to the right. The accessories connection at the top
right is for the starter. The pipe to the left of this
is the main lubrication oil feed to the gearbox. |
|
|
|
Pipe work has now started
to be reattached, and some blanking & re-routing will have
to be done.
At this point there is nothing more I can do on this project
until I get a manual. I am running the risk of 'a little
knowledge is a bad thing' with the CR201 through the lack
of fuel, oil and venting system diagrammatics.
So its back to a patience game.

Anyone got a manual for a CR201?
Thank you Ian Bennett !!!
what would I have done without you?
Ian has very kindly taken some of his time to send me a
manual for the CR201 and hopefully this will lead me to
getting
it up and running as a Turbo Jet. |
