Battery Tray/Box Buffer and backing

[svenedin]

Does anybody know how the 2x battery buffers are attached? Are they just pushed in like a grommet? Part number ADA6357

Also the plastic type material at the back of the battery tray. What is this and what have people used to replace it? I will have to take it off to paint the engine bay. Was this originally on the bottom of the battery tray as well?

The Buffers, or in the official nomenclature, 'Cushion - Battery' are pushed in.
ESM have them https://www.morrisminorspares.com/search/ada6357

There were actually 2 items of the sheet material, as illustrated. With a Home/Export variation too...

The rubber buffers have a locating lip and are just pushed in. I replaced my backing with a piece odd rubber or plastic matting that I picked up at work. It was about 2mm thick and has a mottled pattern.

On a car that has been converted to negative earth but keeping its old battery you might want to slide a bit of wood in behind the battery it bring it forward a little in order to increase the distance between terminal clamps and body...of do the 'buffers' do the job?

Michael,
the Posts are supposed to be at the back, so on converting a car from Pos to Neg Earth, with the 'original battery' you would actually be moving the posts to the front, thus nowhere near the bodywork.
Plus, with a 12v car battery, the mere suggestion of an air gap (just a mm or so) is more than sufficient.

Minors end up with Battery Posts at the front because they have been converted to Neg Earth using the original battery at some point in decades past and the owner, or more likely subsequent owners, have simply replaced 'like-for-like' instead of thinking to get one with the opposite post configuration.

The LCV version of the Parts List illustrates the battery, but designates it as a None Serviceable Part, a rather strange designation presumably meaning a Morris Dealer wouldn't be able to obtain it via the Morris/BMC parts supply system..
Note the position of the terminal posts.

These cars were originally positive earth with the battery posts to the rear as the photo above shows. If you use the same battery and turn it around during a conversion to negative earth then the potential danger is from the battery posts shorting out on the battery clamp - not the car's bodywork

In normal circumstances, yes the rubber buffers are perfectly adequate to help position the battery. The live (negative) terminal being a safe distance from the bulkhead.

My car is positive earth and the battery terminals are correctly at the back.

Thank you for confirming that the battery cushion/buffers just push in.

Berni your parts book is far superior to my ex-MoD abridged version. Thank you for the details. Which book do you have? I should try to get a copy.

It's a pdf download that's on a few different sites.
This one for example : http://www.caroholic.com/63_morris.htm
AKD 3541 is Service Parts List
AKD 3542 is Body Service Parts List.

Oddly, the 'Heater' appears in the Body list....
These publications only cover the 1000 model, but I also found elsewhere the LCV versions ( AKD 3574/3575), which cover all LCV models, thus giving me some SII insights for my car.

Fantastic. Thank you.

I found an old thread now that I know that the rubber sheet is called "seal-spit-hole-dash" and a chap called Mark Wilson did a very nice job with grooved rubber sheet and the bung that earlier cars use (it also fits the later cars because the hole is the same) but he didn't put the buffers back I suspect because he used sound deadening underneath and it would have been too thick for the buffers to work. viewtopic.php?t=73928

My battery has fairly central terminal so could be fitted either way around without fear of touching.

Apologies for my mistake. I think it best I learn more about the car before I make any suggestions!

No problem, all part of the learning curve with these motors.

I find one of the biggest reasons people make 'odd suggestions' is that they will make them based solely on their own vehicle, whatever the year of model, regardless of whether it's to original spec or not. They seem to think all Minors are the same for some reason...

These vehicles are up to 77 years old, with a rolling introduction of changes (during the earlier years in particular), a few significant model changes (MM/SII/S3/S5), plus changes to overseas/LHD models at different years to 'Home Market'.
So it really is a minefield for the new owner.
If you're curious/keen to know the general timeline of development, the Original Morris Minor by Ray Newell is probably the best book.
Used copies are upwards of around £15, new from around £25.
