[xj] Correct orientation of deceleration valve XJ6

And Blakey has already answered my question (thanks And) but I
thought someone might run into this situation and not know how to
install the deceleration valve. (Yes Bob, the digital camera works
great during tear-down if they don’t get wiped out inadvertently).

Under the Air Distribution Block is a valve consisting of a spring
and diaphragm. The Service Manual and the Haynes manual both have
the valve�s orientation wrong. The large washer-like piece goes on
the bottom and fits into the recessed hole in the intake manifold,
with the spring up. The manuals have it the other way around.

I questioned the way I installed it after looking at the books.
David Boger was kind enough to tear one down and send a picture
(thanks David), which matched my installation. Here are the
pictures.

Also, while installing the Air Distribution Block, I epoxy glued a
7/32� hex drive bit (about 1-1/4� long) into the idle speed screw
so it could be fully turned easier with a wrench. This method is
only a slight variation on the suggestions made by others on this
site. Cutting off and Allen wrench is about the same but this was
easier and there were a couple of missing drive bits in the set
anyway.

G’day Alan,
The manual is incorrect. This is really
a non - issue because the valve can only be
fitted one way, the spring is too large in
diameter to go into the hole. If you fit a radio
knob, the type with grub screw fixing, to your
hex drive bit you won’t need the wrench either.

Great suggestion John. I’ll try the knob approach…Alan–
