Making Engine Mounts

[benjy_b]

Hi all, I’m in the process of making some engine mounts to fit a Mercedes OM605 diesel engine into my E36 BMW.

I’ve created the mounting plates on the engine and they’re bolted in place. I’ve also fitted OE style engine rubber mounts and created a plate to fit in top of them.

Now I’m wanting to link the two together. My thought process is to use come “cardboard aided design” and then replicate that into steel.

Does anyone have any tricks or tips when doing this process?
How do I ensure the mounts are straight and true?
Are there any simple ‘go to’ designs to use?

Everything is being made out of 5mm mild steel sheet.

Thanks in advance, Ben

Hmm, How longs a bit of string? There are other factors you've not mentioned to consider. For instance how far apart are they? What's the height difference? Are they inline? Have a look at how the manufacturers, not just BMW and Merc, have done it because they will have done load calculations for the size and shape of materials.

Having said that probably the easiest way is to use box section because it's strong and looks neat, It can easily be folded up in cardboard to find out the angles to fit and then replicate in steel.

i fitted a b230 in my compact, i measured the crank to centre of the chassis legs, then made the mounts... i used 25mm solid steel bar... ok its heavy, but for the length i used, it wasnt that much, and i gusseted it to the mounts too...

don't over complicate it!
