Underseat fuel tank rubber mounts

S2 s2a dont have the single rubber mount due to a hell of a lot less chassis flex due to the welded box section chassis design.

Simples....[emoji2] [emoji2] [emoji2]

Hope this clears it up for all of you...[emoji106]

This only applies to 109 chassis not neccesarily 88. However for production commonality they may or may not have had the single bolt on 88.

Would records show this? I know in modern times, in R&D, we used to have to record everything.

Hello again from Brisbane.

A reasonable proposition I suppose. However, hard to know how to follow it up - if for no more human reason than a Company's likely reluctance to confess to the need to rectify some piece or other of poor initial design (apologies to the true believers).

My own thoughts are a bit mixed, especially after watching the last few episodes of the great bridges of Britain. Foremost, the railway bridge that Stephenson built to span the Menai Strait - a true marvel of Victorian engineering. The key to its success was the box section design of the main spans that gave great carrying capacity for a relatively light weight. This revolutionary design was based on plant stalks and continues to be used across the globe to the present day. Climbing down from the Pathe hyperbole, Series Land Rovers all (?) have a box section chassis, a key element of their toughness - so despite the use of thinner plate in the later chassis the question arises of whether there is enough flex to crack a rigidly mounted tank?

I retreat to my suggestion that some engineer likely took a look at the arrangement and decided that it might be timely to go for a single rubber bushed bolt for a change.

Cheers,

Neil

Possibly came to accompany a change in tank design, for example, a change in wall thickness, or a change in the type of solder used, for example, and like many changes to Series (and later) vehicles, may have only been documented as "alternatives", or not documented at all. The main reason for this is that Landrovers were at this time being built in a number of different places, and some of these, for example, Australia and Spain, were making a substantial proportion of the vehicle parts. This meant that they would be very resistant to change if it did not involve the parts they were importing from Solihull.
