Early front shock absorbers Girling NF 64054173

I've got two original early front shocks: Girling NF 64054173 and the Haddock/Mueller original guide which quotes that the original paint is supposed to be a pale grey/blue. My ones are black and I believe the colour to be original. At least definitely unchanged since 1994 but maybe related to the car's original colour: black. The car was changed to a light blue at some time in the past (most likely in the 70s/80s). But everything under the hood remained mostly original.

I have folded posts #277 'Early Heater Box' and #278 'Very early heater blower motors' into the earlier post #164 to keep everything we know concerning these items in one place. I have also added some more content: http://forum.etypeuk.com/viewtopic.php?p=58877#p58877

I believe the original front shocks on 875343 are black as well, but it is difficult to tell with all the rust.

OTS Hood Rear Window

The rear window of the hood was made from Vybak plastic, a soft felexible formulation having good clarity, weather resistance and stitchable. It was produced and supplied by Bakelite Ltd.
Image

Original rear windows are very rare as despite the quality and UV resistance of Vybak it scratches easily and dulls over time. The plastic can be unstitched and replaced relatively easily. Vybak is still available today as it is used in automotive and marine applications. The one thing that is not replicated are the original name, numbers and care instructions embossed in the lower left corner:
Image

If you have an original hood the Vybak plastic can be restored and the best product to use is Meguiars Plast RX Clear Plastic Cleaner & Polish together with an orbital polisher as long as you are carful not to heat up the plastic as it will stretch!

Hi

I'm not sure about the value of this information but, with reference to post #5 of this topic and the "HEAD LAMP vs HEADLAMP" dipswitch escutcheon difference. My car, which rolled off the production line on 28th December 1962, has the HEADLAMP escutcheon so Dave's note that it changed in late 1962 is correct - they were still rolling out with the originals between Christmas and New Year!

Probably a bit of mix and match going on.

Regards

PS - I haven't been able to find any pictures of this detail in the originality and restoration books by Klausager, Porter or Barzilay. The photographs always seem to have it cropped out.

Maybe another interesting observation from two welded louvers center sections (one supposedly from 875443 - I bought it off the then owner like 3? years ago and it shows the original colour as well as the resprayed one) and another I disassembled just a few days ago.

After putting them in a row, starting with a newer Series 1 center section, I could identify some regular and on purpose made bends in all 4 flanges of the welded louvers center sections:

And one more.

The flanges on the welded louver bonnets are approx 2 mm shorter than on the other, later Series 1 bonnet (not sure, if this is a 3.8 or 4.2). But it is an original one...

And yes, the first picture is a bit misleading. But it is clear below 2.5cm and also approx 2.3cm tall.

I'm not sure a 2mm difference in flange size is an indicator of originality, especially when ought to have been measured in fractions of an inch anyway.

It does remind me of one detail previously overlooked:- the first hundred or so cars have the Sikaflex bonded in on these flanges is going from right to left and all of the subsequent ones show the little bead of goop at the other end thereafter, i.e. the caulking gun ran from left to right. This isn't as daft as it it seams. The guy on that part of the line was left handed and when Jaguar set up a proper bonnet assembly line, he moved on and was replaced by someone right handed.

kind regards
Marek

An April first specimen methinks... Being left-handed but somewhat ambidextrous runs in my father’s family. ‘Seams’ I could have earned double time at Jaguar, and quadruple on holidays :-)

As to Wagstean’s point, it would be interesting to know if the extra metal was equal on both sides - indicating more generous trimming after pressing, or slightly lop-sided, indicating variable placement of the blank sheet in the press.

Alternatively, all blanks could be identical but the folding point varied fractionally on each edge. The dimension I would expect least variance would be the distance between opposing holes measured across the panel, but that would be very hard to measure accurately and consistently.

@Peter (as otgers might not be intereated): the flanges are wider on both sides. So the panels were of different size or a different pressing method / tool was used. David once wrote that they used concrete in the beginning. Maybe this is the reason?!

Front and Rear Brake Cylinders
Image

Up until cars 850253/860022/875963/885142 (December1961) the front and rear brake cylinders were made of Malleable Iron. On all subsequent cars the brake cylinders were Cast Iron. 'C' was added to the casting to denote the later cast iron cylinders. Malleable Iron starts out as Cast Iron but is heat treated (annealed) which gives it properties similar to mild steel and. After annealing the item was plunged into oil for rust protection and giving the item a matt black finish. It is easy to machine and is shock resistant. Jaguar probably moved to Cast Iron on cost grounds saving money on the annealing process but used a plating process for rust protection. The Mk2 saloons changed to Cast Iron in June 1961.

The early cylinders also had a separate piston and backing plate so the parts are not interchangeable with the later cylinders.

Image

Front Cast Iron cylinder 8777 (VBO.5505) showing the 'C' mark in front of the piston size:
Image

The early cylinders used a two part piston attached with two screws and the self-adjusting rod held in place by a plate with six holes and crimped to the cylinder.
Image
Image
Image

The later cylinders used a one piece piston and the self adjusting rod was retained in a simpler way:
Image

The rear 1 3/4" cylinders 8514 (VBO.5375) were also Malleable Iron with multi part piston:
Image
Image

Image

The later rear Cast Iron cylinders 8778 (VBO.5506) had the 'C' mark:
Image

The Malleable Iron cylinders are quite rare as they were only fitted to 1,380 cars, a service item with limited spares availability and so scrapped on failure. For a concours or original car the front ones are essential as the markings can be easily seen through the wheel spokes. Not so much a problem with the rear as they are impossible to see unless the car is on a ramp. Also be aware Dunlop cylinders were fitted to many cars (Aston Martin, Ferrari, MG, Jaguar saloons etc) but the piston sizes vary depending on the application. For the E-Type you need 2 1/8" front and 1 3/4" rear cylinders but many are offered in the wrong size but claiming to be for the E-Type

Trivia:
1. The Jaguar Mk2 saloons used Malleable Iron #8513 cylinders until June 1961 after which they were Cast Iron. From February 1962 "in the interests of standardisation" the front cylimders #8777 were identical to those fitted to the E-Type.

2. The E-Type brake pad material was changed from Mintex 40 to Mintex 33 with the introduction of the Cast Iron cylinders.

3. The brakes for the XK150S were not carried forward to the E-Type.

Note: If anyone has photos of the early rear brake cylinders without the C marking I would be very grateful to receive them
