Planning to attempt salvage of a 1984 SJ6 VDP. Never worked on this era Jag before. What are the fasteners -- U.S., Metric, British Standard (Whitworth), or will I find a mixture?

I need to prepare a small tool set for getting the vehicle out of the junkyard.

 

Almost all USA/Imperial. 95% if I had to toss out a guess

A few metric, a couple whitworth.

Thanks again Doug,
This was what I had expected. Obviously lots of care is needed to avoid installing a "close fit" bolt into the wrong threaded hole. I own all three sets of tools, with exception of Whitworth taps and dies. Maybe time to invest in a good set.

The only Whitworth I've found on my similar car were on the drive shaft at the transmission ands the differential. As I get lucky from time to time, I had two Whitworth ring wrenches. One fit!!!


O'wise all else seems USA.

When you go to the junkyard be sure to take a breaker bar and deep standard sockets for the wheel lugs. Even if it has the original lug wrench it will probably be impossible to get the lug nuts off.

 

Thanks Yellow series 3. In anticipation, I negotiated that the junkyard would remove the wheels so I could have used, temporary ones installed.

 

Thanks for the info Carl. If my memory is good, MG-B also had Whitworth drive shaft nuts. I own the tools. Haven't worked on a Jag newer than 68 (many years ago). I was hoping by 1984 the car was standardized, but of course then it would lose some of its distinction.

 

the "phillips" screws are Pozi Drive.

the tire lugnut wrench in the jack bag is good for the sump oil drain plug.

in my car, most engine bolts are Metric, 8mm, 10mm, 13mm, 19mm, 22mm.

 

Be very careful with the brake pipe unions. Jaguar converted these to metric in the early 80s and my workshop manual contained a warning about the difference. Apparently the hexagons were marked in some way.

Apart from this it will be almost all UNF/UNC and some BA in the electrics department. In my work on a 1980 XJ6 in the late 80s/early 90s I didn't come across anything unusual. Where a bought-in component came from Europe it will be metric. Not sure if Jaguar bought anything outside England, we still had an engineering industry then !!

PS
If you have the parts handbook, the fasteners have a code that indicates diameter and length for normal UNF stuff. I found this very useful once I had decoded this, as I could then order stainless fasteners without measuring up. Bolts that are special in some way, have individual part numbers.

 

Jaguar bought lots of stuff from Ford and General Motors starting in the 1960's, and who knows if prior to.

The XJ have Borg Warner auto transmissions, Delco Saginaw power steering pumps, Adwest rack & pinion racks, Delco Air Pumps, Delco ignition amplifiers, Delanair a/c systems (that last one is iffy, but I hear they were in Texas?).

The MK-1, MK-2, S type and 420 have Ford Tractor power steering systems, and Borg Warner auto transmissions.

multiply the amount of cars made since 1963 by the amount of those parts, and that was a lot of parts and components purchased from outside England.

Daimlers too!

 

Thanks Jose,
Especially for the Pos-Drive info. Correct screwdriver can make a big difference with seized / corroded threads.

Lauriston, you welcome.

you can download from here, the Service and Parts Manual Sections for the Series 3 XJ-6.

go to the sticky XJ6 & XJ12 'HOW TO' quick links at the top of this page, then scroll down until you see the file links. Download one .pdf file at a time. (Engine, Body, Electrical, etc.,etc.)

 

For those interested in trivia.....


"Delanair" systems were manufactured by Delaney Gallay in the UK. They made heating/ventilation systems (and other stuff, like seat belts) for just about anything with wheels. As I recall the company was bought by Valeo....another company making all sorts of automotive components.

However there IS a Texas tie-in with Jaguar air conditioners......

In the late 50s/early 60s it was a company in Texas who designed (and manufactured?) add-on air conditioning for Jaguar dealers to install some of Jaguar's models. As far as I know these were 'factory authorized' kits.

Or something like that. I can't remember the exact details.

Just wondering. It was in the late 50's that add on AC units were becoming popular. Under the dash mounts. My company provided 57 Bare bones 150 Chevrolet tudor powered by as tick shift six had one added. A Mark IV.
by name. Barely adequate in CA's Imperial Valley where I worked ! Perhaps ?. I might just look, my curiosity is up!!!

...were supplied by Adwest Engineering in Reading, England: an English, not American, company

 

North Americans who went to England I bet.

Actually I think those racks in the Series 3 XJ are from General Motors.

 

All the Series III racks I've seen were clearly identified as Adwest brand, which was a UK company.....although it seems possible that GM may have had some ownership at the corporate level at some point, given how convoluted corporate parentage can become.

when I needed to replace my leaker rack around 1996-97, (just guessing the year), I asked my trusty Nashville mechanic where I could find decent rebuilt racks. He referred me to a firm in Atlanta.

I called them and and asked if they had a non-leaker for a 1984 XJ-6, the reply was: "sure, that's a GM rack". "GM?" I asked, "GM" he said.

Ok, so I need one yesterday. Was told there was a core charge and when I return my old one in the box provided with the new one, they will credit me back for the core.

when the new one arrived I compared it carefully to the old rack, they were identical, so down came the old one and up the new one complete with John's Cars anti-side sway kit.

That's the rack I still have today, still not leaking.

Is it a GM rack? I have no clue, all I know is what I've been told. Not that it matters, I really don't have any issue with it being Adwest or GM, I saw no markings on either rack, so I assumed they were both GM.

but surely it is a matter worth investigating, considering so many other GM components in these cars, who knows if the racks are indeed GM. I sure don't.

Also by the way, replacement racks for XJ-6 are sold by Autozone and Advance Auto Parts, Car Quest, O'Reilly's, and who knows who else. Shop around, prices become enormous when you say "Jaguar".

 

Sorry, no and no

Adwest was formed by merger of a couple of old British companies, Adamant Engineering (Luton, 1878) and Western Manufacturing (Reading, 1929). Neither was American-founded and neither was ever owned by GM. It was a bigger firm, but their steering tech was licensed beginning 1921 from a UK company called Marles, which they bought in 1946.

FWIW, my 1987 Series III has a plate on the (original) rack that says Adwest on it...

 

So true
