Wedge List / Catalytic Converter Precautions
« Last post by "Brian" on June 05, 2018, 03:04:26 PM »
Does anyone on the list have a "Catalytic Converter Precautions" warning

label on the top part of the passenger sun visor of an early (up to 1977 or

so) TR7 or TR8 fixed head?  (or perhaps a Jaguar XJ6).  If you do, please

send a copy!

I am trying to track down part UKC7857 which is in most of the catalogues as

that label Precautions  (including the convertible catalogues by which time

it seems to have stopped being used altogether as a label on how to close

the hood (soft top) replaced it.  The parts books were never corrected and

the earlier part remains in the 1981 catalogues!

I have seen an earlier version with black and red text on white with a

different part number (24590-EX), but am trying to find the actual one

labelled  "UKC7857".  If may be that it does not exist except in the TR7/8

parts book of November 1977!

There are a number of errors in the various parts books sadly.

If you TR is stock, go with the profile of the tires it came with.  I have

Stag and the tires are a lower profile than original. The diameter is about

1.5" smaller. In my case, the ride height is correct and there is to much

of a gap between wheel arch and tire and it looks odd.  I suppose if your

car is not sitting at the correct ride height , due to sagging road

springs, then getting a lower profile tire wont look that odd.

As mentioned, the speedo is off when you use a lower profile too, but i'm

sure no one has gotten a speeding ticket for driving 1 or 2 miles higher

than the posted limit.

185/70/13 is stock and there are somewhat decent tire choices.  205/60/13 is,

or at least use to be the upsize of choice on stock rims.  Problem is, tire

choices are limited to third world ghetto cart wheels and race tires.  One

exception, and very few people know about this, so keep it a secret.  There is

a racing series called Legends cars.  They are 3/4 scale 1930s looking race

cars.  The spec tire for the race series is a Federal 595.  They are only made

for the race series.  You have to buy them from a race car vendor that deals

with Legends cars.  The good is they are $100 to $110 a piece.  They are a 200

tread wear street tire, and that is what was speced for the series in order to

keep costs down.  Guys can get a whole year of racing out of a set of tires.

The bad is they are not DOT approved.  All of the 595s available in other

sizes are approved.  The other bad is that they are getting harder to find

unshaved at full tread depth.  The racers have taken to camber cutting the

tires so that the circumference of the tires is smaller on the inside than it

is on the outside.  Faster lap times if your constantly turning left.  If you

can find a local shop, drop in, lay down $400 and walk out with a great set of

tires.  That being said, I just ordered another set of Falken Azenis 205/50/15

RT615K+ 200 tread wear tires for one of my 8s.  Donbt see the point in

sticking with the 13 inch wheels any more, especially considering the fact

that you need bigger wheels to fit bigger brakes.  My only wedge that still

sports 13s is my TR7 coupe, and thats because it came with a nice set of 13b

minilites.  All of the 8s have 15, 16 or 17b wheels depending on the level

of performance.  Whatever you decide to do, try to find a tire that has a tire

height of around 23b in order to keep the speedo correct.  Any changes to

the tires overall height or final drive ratios will mean you have to play with

speedo gears to get it right.  A 24b tall tire will still fit but may rub

the front spring perch.  A 25b tall tire wonbt without major mods.

185 width is stock, so no problem there, but it's 1.5" smaller diameter

than stock, and stock is already tiny, so that's probably going to look

strange.  And the speedometer will be off by 6.5%

A quick search suggests that 185-60 is primarily available in racing

tires and they cost 2-3x what the cheapest 185-70 cost.

Hi All,

Has anyone tried 185/60 13 on a TR7? I'm looking for new tires and the price

of 205/60 13's are way out of my price range. The 185 is about .75 less in

width and about 1 inch less in height. Any thoughts or comments?

If you have a 1980 Federal US market Spider special edition, anbd those are

the original carbs, they ain't SUs, they're Strombergs. And if oil is leaking

from the air valve dashpots, it's because the O ring on the needle adjuster is

shot. SU carbs have no such O ring because the needles are not adjustable.

I have been having an issue with needing to fill damper oil into the one

carburetor that is nearest the interior.   Like every time I am done

driving it.  Any ideas what may be causing this and what I should be

looking for?

Wedge List / TSI thrust bearing strut pivot question
« Last post by "Allen Brenden" on June 02, 2018, 04:55:58 PM »
Hi all.

I've lost the instructions to Ted's thrust bearing strut pivot kit. Got most

of it figured out, except for the white nylon spacer that goes on after the

thrust bearing. Does the step of the spacer go up or down? I sent Ted an

email, but don't expect an answer  right away. Can anyone help?

The major weak part of the drive train in early TR7's was the 4 speed tranny

not the diff. MG Midget diffs were pure junk.  An extra six pack in the boot

was too much for the diff!!

And also the later models spitfire/Herald/GT6 maybe?

Or was that the transmission and overdrive?
