Sump cover replacement

[WealdenManinKent]

Hi Guys,

I have an early '73 manual with a 'A' type overdrive and the sump has two brackets spot welded on the sides and bolted back onto the rear engine plate. I presume this is some kind of anti-vibration device?

I decided to replace the sump as it has suffered impact damaged in the past and the drain plug has been cross threaded in the past by some moron!!
Obtaining a replacement (which is in great condition) from a usual stag parts supplier, this sump doesn’t have the side brackets.

Anyone knows if this is an issue if I simply remove the brackets on the engine rear plate and go without? Or will this bring on some kind of vibration issue?
Or should I transfer the brackets and spot weld them onto the replacement sump?

Postcript - According to parts listing its called a clutch housing extension Bracket/Strap and on the spec plate the car was an original manual with overdrive. (It shows the O after the LD production number)

Hi Roger,

I believe that these brackets were only needed for the automatic cars, but if I'm wrong, I'm sure somebody will be along soon to say so!

Not sure why they are needed but the are on my car 1972 MOD version.
It looks like they provide bracing from the bottom of the Gearbox adaptor plate to the sump/ engine. Could be to do with Vibration / stress but as its to the sump I hardly think it can provide much re-enforcement.
But see if any other wise old owls have the answer, I'm but a fledgeling!!

I read somewhere that it was an anti-vibration feature.

I think it was an addition to automatics, as Duncan says.

Got them on my '77 MOD.

Was yours always a MOD? A lot of of autos were converted to MOD and the brackets transferred?

I think mine has them too. Definately a MOD and always has been. Can't find a piccie at the mo.

Thanks for the comments so far guys; Looking at an automatic setup, the same Stiffener is mounted upon that - It seems these stiffeners were fitted to manuals as well as automatics as several of you have confirmed it is mounted onto your cars?? I am tempted to just transfer brackets and keep set up as is!

Yep, Heritage cert confirms that and the brackets look original, as Roger says above.

For those who don't know what we're talking about, here's a piccie of the mating brackets on the gearbox, with the sump removed.

For any more doubting Thomases out there....! (1974 MOD)

If I were to place bets on their purpose, I would say that they are there simply to provide a support/attachment to the lower part of the adaptor plate. Otherwise, it's quite a long way from the lowest gearbox bolts up to the area where the adaptor plate is fixed to a solid surface.

Ok chaps and thanks for all your support - so it seems something learned for us all> I will have to transfer the brackets from the old sump to the nice clean shiny 'replacement' sump.
