Stupid Question: whats wrong with different engine mount rubbers
davidosullivan - 12/12/07 at 01:40 PM

Ok, I was reading a thread the other day that suggested buying new engine mount rubbers before measuring up to make the engine mounts.... fair point!

So my stupid question. is there any reason why I shouldn't buy different mounts to the originals?

I cant see an issue, unless there is some thing about shock absorbance/weight of engine or something?

Having said all that I'm using a 1.6 pinto out of a 70s capri so I expect the factors will have some anyway.

Cheers,
D

I have used transit diesel mounts on my falcons pinto in the past. Their quite large but the rubber is so soft you can dig your nails into it. Can't feel a thing from the engine even with a mild race cam.

No reason not to use other things, I used panard rod bushes on mine, gives a captive mount in case of bush failure.

Panhard Rod Bushes? you mean the chassis end of your mounts hold the bush, and then it has a u-bracket??

As with all threads these days... any photos would be great.

I'll be making the whole mounts (probably over Christmas) so just checking out the options.

Cheers.

... looked through your archive and couldnt see any

MK and others use the big square landrover engine mounts with a threaded stud either side. Cheap, almost solid (which stops the engine moving around to much) and dead easy to design around.


Mr Whippy - 12/12/07 at 03:33 PM

really there's no correct answer just depends on what your after but certainly try other mounts, the ford ones were rather basic.

Land-Rover ones are very cheap and a lot stiffer


Mr Whippy - 12/12/07 at 03:57 PM

No softers better.…...yes! It’s the softer v harder war!, time for a blazing rant!!!

Hi have a look in my photo archives under engine stabiliser mounting it will help you

One thing to bear in mind, if you have long engine mounts, i.e. sticking out a long way from the block, use softer rubbers, hard rubbers can lead to the mounts fracturing due to the tourque of the engine needing to flex the mounts on acceleration / deceleration.

Vice versa, soft rubbers close to the engine centre can lead to too much engine movement.

Again no real right or wrong just needs a balance.

Another "I used Land-Rover diesel ones too" post

They allow almost no engine movement at all I like to feel the engine through the chassis


davidosullivan - 14/12/07 at 03:18 PM

So long mounts = soft rubbers and short mounts = hard rubbers.

As I currently only have the capri ones to go on, does anyone know if they're considered hard or soft?

They're a cylindrical rubber with a stud on each side.

a bit like this... linky linkerson but without the metal engine mounts

Hi,

I use the original mountings also.
The original take a lot of space and are mounted on an angle.

So your exhaust and your steering-shaft could cause problems.

Good luck, don't be scared to walk an other path.

Look into my photo-archive...

Having the engine and gearbox flopping around isn't a great idea in a locost with limited clearances!

Soft engine mounts are perfect for production cars where you want as much vibration absorbed as possible. On something like a Locost you want a nice direct link between the road and the engine.
