Engine Mount Design
DH2 - 23/4/12 at 12:52 PM

Hi all.

I have been looking and thinking about mounting my new engine in the chassis.
Are there any rules, or generally recognised ideas, with regard to how to do this? I have bought a pair of the Land Rover rubber mounts - what orientation are they employed in a Landy, horizontal or at an angle? What sort of material thicknesses should I be looking at using? Is 3mm steel enough?

Thanks Log' - I remember seeing that thread now you mention it.
Here's a "composite" one I was having a play with yesterday, so I guess I am on the right track...



Oh and some Google searching seems to suggest that the LR mounts are installed at a slight angle - I arbitrarily went for about 30 degrees on my mock-up.

Mockup does look similar, but there would be no way to reach the top nut, and I wouldnt just want to drill a hole in the tube to reach it as it would be a weak spot.
I plan on copying the Raw mount I posted, and mounting mine Horizontal. The land rover mounts are just blocks of rubber, so I would suggest anywhere between horizontal and about 30degress would be fine.

Both my LR mounts are verticle on the striker? Are yours different loggy?

I havent made them yet, the picture I posted on the other thread are the Raw ones I assumed were factory, which I was going to order, but at £45+vat, I knew I could do it alot cheaper (less than £25!)

What is the over complicated rose joint bit for ?



The angle on of the Mount to a landrover chassis is approx 45 Deg's

The top nut would have to be captive in that example... not quite as flexible in terms fitting the engine, but with the rubber mount at an angle, there isn't much choice.
I think having the rubber at an angle makes some sense, as per the post in the thread you linked - there is maximum resistance to movement in compression of the rubber mount, and this is what you want to resist the engine rocking, but it will allow some movement in other planes.

That's my current thinking anyway. Thanks for the advice, all.

Edit to add: no, not the thread you linked, one I searched - here.

Hi the rose joint part i added to the MK engine mount as a stabiliser for the engine as the alternator pulley use to hit the chassis

my variation for the Duratec install on my Striker...........got to be better than the one that was supposed to holding the Crossflow I took out !!!
