Engine/Transmission rubber

[Tom.H]

Hi

A quick question:

How Does the rubber used for transmission mounting compare to the rubber used for engine mounting?

Engine mount Rubber

Part number: ANR1808 http://www.lrseries.com/shop/product/listing/2870/ANR1808-ENGINE-MOUNTING-RUBBER.html?search=ANR1808&page=1

I only ask because I’ve completely ‘re done’ the engine mount brackets on my vehicle. They used to use the rubber from radius arms bushes and not surprisingly they didn’t absorb much of the vibration. The bracket I now have allow me to use normal engine mount rubber used on rover V8 and TDI’s

I thought there would be a vast improvement in vibration however there isn’t. I picked out the mounts I used from a box of gearbox/engine mounts. Basically there might be a possibility I’ve used transmission rubber instead of engine mount rubber, as they both look familiar

Does anyone know if the transmission rubber is stiffer than engine mount rubber? Could this the possible reason why there is no improvement in the vibration going through my vehicle?

As far as I know the rubber type is identical, just the pad area of the bushes. - how bad is bad vibration?

Where are your replacement mounts from? There has been some discussion on here along the lines of the pattern parts being harder than the genuine LR items.

The Vibration is quite bad. After replacing the mount I notice that the transfer box was pushed against the chassis. With it now moved away there is an improvement however I still think it’s no way as smooth as a normal land rover 90

I don’t know where the mounts are from. They aren’t new and were basically picked out from a box of odd mounts. The reason I didn’t start off with new ones is because they were left in when the brackets were welded onto the chassis and I thought they would have melted

They don’t seem to have become damaged from being welded however I am up for replacing the mounts with new ones.

Microcat shows rubber mount KKB103120 for V8 4.0 ltr engines only,

for 200Tdi & gearbox you need ANR1808, got these on my 200Tdi/R380 110 no vib problems with them.

I got new ANR1808s a while back to put under my transmission, and the vibration was very bad to begin with.

It has now got a lot better (I imagine the rubber has stretched/softened with the movement), but next time I will use Genuine to be sure

I would agree. I had to use Sh!tpart, as I was on a deadline for an MOT, and they were definitely pretty hard, but I would say they've softened up a bit.

Given the chance, I'd buy genuine.

Having an ANR1808 in front of me, the Engine mounts are:- metal disc | rubber | metal disc | rubber | metal disc

The transmission mounts are:- metal disc | rubber | metal disc

And from memory the Transmission mounts offer slightly more flex, but I still rip either type from the mountings as my engine tries to escape
