[E-Type] Errata in Jaguar ROMs and Parts Books - Post 1

E-Type
1

The following is a compilation of errors I’ve discovered in
12 years of E-Type Series 3 ownership, restoration, and
repair. It is in no way all of what may be wrong or
questionable, but is mainly to save you time and pause to
verify things when working on your car…all so we can
drive them more! Most of my knowledge is relative to the 2+2
but also applies to the OTS. Any OTS specific additions
would be great. My Parts Book references are the Series 3
2+2 FHC RTC9015 Feb 1974, but can also be found in the
alternate pages of the OTS book. Why British Leyland didn’t
keep the same page numbers between the 2 books I’ll never
know! Remember that the parts books were not reassembly
manuals, only reference for the parts techs at he dealers.
Since we don’t have true assembly manuals for the E-Types,
we tend to use them as bible. Beware! Even the ROMs can be
wrong too.

Please add to this thread if you know of something wrong or
questionable. I am volunteering to research, diagnose,
investigate, and document this information. If we discover
errors in the errata, let’s work together to try to solve
it. I will assign index numbers to each note to keep
tracking easy. They’re not in any specific order, but can be
categorized later in my document. When you add something,
increment the number, or reference an earlier index number.

One more note. I have to add a disclaimer(argh!). This is
for information purposes only and the users of this
information must be aware it could be wrong. Use it at your
own risk/pleasure. Sorry but I had to add this.

Here goes:

1 - RTC9015 p31.48 ‘‘Master Cylinder - Reaction Valve’’
Exploded view of internals(bottom of page) wrong. Also shown
wrong in ROM rebuild section. The 10878 ‘‘plastic seal
retainer cup’’ and ‘‘NSS’’ seal are shown incorrectly. The open
lip of the seal and cup must face inwards to maintain fluid
pressure. I will add a diagram in the document. I will also
add a diagram of the reaction valve internals as none exist.
Assembly is not obvious and can be assembled backwards.

2 - RTC9015 p31.27 ‘‘Front Suspension-Lower Wishbone’’ Lower
right in diagram, C15376 - 4 off big washers. There are only
2 total, 1 per side.

3 - RTC9015 p31.29 ‘‘Front Suspension’’ Lower right in
diagram, 8 UFB.131/8R bolts upside down. Nuts are on the
outside.

4 - RTC9015 p31.64 & p31.66 ‘‘Power Steering Unit’’ Note only
the RHD version is shown, not LHD. Same error in ROM rebuild
section. Pressure pipes (12711-short, & 12712-long) are
shown going to the pinion valve incorrectly. Should be: The
short pipe must go to bottom hole pictured in pinion
valve(i.e. when on car the forward hole). The long pipe in
the hole towards steering wheel). If these get reversed,
steering will ‘‘hard lock’’ by itself if you try to turn
steering wheel, possibly causing serious injury to your
body. (Don’t ask how I know this!)

…continued.

5- RTC9015 p32.03 ‘‘Fan Cowl and Air Deflector’’ or radiator
shroud as I call it. C33960 deflector is shown upside down.
Note the notch on the upper left side. It is to clear the
lower radiator bracket C32825.

6 - RTC9015 p32.20 ‘‘Petrol Vent Pipes - Ex/Em’’(early type)
C32827 Metal charcoal canister. Bottom tubing is actually
elbowed towards right of car(not towards engine). Pic is
wrong. The C38511/8 hose must be long enough to reach it.
The top hose C30757/3 goes to the C34929 pipe shown on
p30.21 upper left corner diagram.

7- RTC9015 p33.02 ‘‘Front Frame’’ - This is a big one. Upon
reassembling the frame rails, if you get this wrong it will
require much reassembly. Note the picture of the ‘‘U’’ shaped
front support C32385,35447. It is shown reversed. See the
curved cutouts in the vertical sides. These mount TOWARD THE
ENGINE. They are cutouts for the alternator, ps pump, and
air pump pulleys. If you mount as shown, the lower wishbone
threaded mounting holes integrated into it will not line up,
thus causing you to curse and have to take it apart and do
it correctly.

8 - RTC9015 p33.22 ‘‘Bonnet Fittings’’ - BD36897 heater duct
uses 3 bolts for assembly and one screw. The top bolt(upper
left corner when viewed from inide bonnet), does not use a
BD.542/3 oval washer. It calls out 3-off. Should be 2-off,
and one round one, I think it’s a FW.104/T.

9 - RTC9015 p30.37 ‘‘Engine - rear mounting’’ - The diagram is
misleading how to reassemble the Auto Unit mount. I will add
a better diagram to the document. I spent a long time
figuring this out because a PO reassembled mine wrong.

…more later. I have to check more notes.–

Rich,

What are referring to by ‘‘ROM’’? Is that the CD version?–

I don’t have the CD. I’m referring to the Repair Operation
Manual, te big blue book E165/2. I would think the CD is a
scanned copy of the paper version. Is that correct?–

…continued.

10 - RTC9015 p32.48 & 32.49 ‘‘Ignition’’ Showing distrubutors
for early and late engines. Notice the exploded views on
both pages at the bottom, showing the centrifugal advance
springs. One has a part number, the other doesn’t. One is a
dark shade of black(with the part #), the other is a light
shade. The 2 springs are not the same, one is
heavier/stronger than the other. I’m not sure what the
actual part #‘s are.
The following is the correct assembly description. Note the
reference should be with the arm of the spring plate towards
left as in the diagram. The heavy spring should be on the
right(note it will be a loose fit so crimp the ends) , the
lighter spring should be on the left. The pictures mislead
you to put the lighter one on the right, and the heavier on
the left. The book is wrong. The ROM tells you on
page/section 86.35.26, steps 9&16, to ‘‘Release’’ or ‘‘Fit’’
control springs’’, but doesn’t tell you which is which either.

11 - RTC9015 p31.68 ‘‘Power Steering Pump’’ - This is an odd
one. A part is missing in the diagram. Since the pump is a
GM issue, and the body/seal assy (#11632) came from them,
it’s already included. The part is inside the body. It is a
round magnet, about 1’’ x 1/2’’ thick, attached to the inside
of the pump in a recess made for it to fit into. This was
used to trap metal particle shavings, which could come off
the pump metal impeller blades. I found mine coated with
particles on rebuild, so I’d say it’s an important part.

12 - RTC9015 p30.15 ‘‘Inlet Manifolds’’ C35728 s/b 2-off(the
bolts with tapped top threads to hold the rain shields), and
UCB.131/32R s/b 6-off, totalling 8 pieces altogether. Early
versions used 4 of each as there were no shield brackets
(C38736 ref p30.16).
13 - RTC9015 p31.29 ‘‘Front Suspension’’ Anti-roll(sway) bar
link attaching bushings and washers not pictured correctly.
See the bolt UFB.143/21R passing through the black rubber
bushing, through C32903 link, the anti-roll bar, then a
beveled washer against the metal link, then the nut. The
beveled washer(FW.207/T) should go between the head of the
UFB.143/21R bolt, and against the rubber bushing. Note that
the washers’ beveled edge should be against the bushing to
compress it into the link. Ref ROM 60.10.02 Anti Roll Bar
Link R&R.

…continued.

14 - RTC9015 p31.46 ‘‘Brake Vacuum Tank - LHD’’ Just to
clarify hose connections shown as ‘‘To Master Cylinder’’. The
top long hose from booster top elbow goes to the plastic
fitting on the air Reaction Valve. The other hose goes to
the metal pipe fitting on the back of the Reaction Valve.

15 - RTC9015 p32.31 - ‘‘Demister Controls’’ Missing reference
to the ‘‘Interior/Defrost’’ label plates that mount
horizontally under the dash with 2 screws just below the
demister knobs.Thes were supplied for certain cars before
they changed to the vertically mounted plates(BD44066,7)

16 - RTC9015 p32.44 ‘‘Alternator Mountings’’ Washer in front
of C34197 has no part#. It’s a special beveled washer to fit
into the mount piece.

17 - RTC9015 p33.55 ‘‘Tool Kit’’ Missing item, the spare tire
hold down. For wire wheels it’s BD36808, round cup, with
captive L shaped bolt, all painted black.------------------------------------------------------------
Done! That’s about all I could come up with. I’m sure there
are more. I’ll give some time for any other additions and
when I get some time I’ll create a doc with diagrams for the
website.

Hope it helps,

Hi Rich, I am working with the parts book RTC 9014 ( which is the OTS
version even though I have the 2+2 ) so I am looking at diagrams 27.48
&27.49. Re those springs… when assembled the heavy spring ( internal length
18.5mm wire diameter 1.28mm ) is directly positioned opposite one of the
three elongated holes/slots used to bolt the assembly to the dizzy case. .
The lighter spring ( internal length 16.1 mm. wire diameter 0.69 mm) when
installed is positioned mid-way between two of the baseplate bolt hole
slots. I have no knowledge of the part #s. I do recall a discussion on the
V12 list that these springs were not available from anyone as parts, but
were available to some distributor refurbishers…so you had to have a full
rebuild to get the springs .Also i recall that the consensus was that it
didn’t really matter which spring went where. I stuck to the layout as
already described , which i have seen on two different V12 dizzies.
Re Steering rack rebuild, 57.10.07 re step 35, overhaul valve and pinion
assembly, 57.10.22.Even though the ROM( E 165 3 )contains 57.10.19,20,23,
and 24, there is no 22. never could find that . I did it anyway, but would
have like to see the words!.
Re Compressor 27.38. idler pulley C.18733 in lower left of diagram is
positioned on the bolt which is shown to have a nut c3968/2. This not needed
as the bolt actually fits into a threaded boss on the mounting plate c.33523
top left of diagram.
All these comments apply to a 1973 S III 2+2. john M Holmes , Ontario.
