Cerbera AJP Engine Mounts

[Jhonno]

Think I need a pair of them.. Seen one of the suppliers has them @£15 atm, but they are just generic round mounts.. Anyone know the dims etc or an alternative source? (Did check Alt Parts Page). Maybe even some uprated ones?

Hi I ordered one the other week from clever Trevor and it was slightly thinner than the original, it also seams a lot harder rubber and does transmit more vibration.
I've been looking online and if you search for male/female bobbins, rubber mounts then quite a few suppliers of anti-vibration mounts come up.
My original mounts are 75mm x 40mm with an M12 bolt, I only found a couple of suppliers which do the exact same size. I'll post up a link when I get home.

I was looking at M12x37 75x40 with a choice of three rubber strengths.

This may or may not be some help; I bought a pair of gearbox mounts, Rubber Mount Male/Female 50x35mm M10 Thread, off eBay from small_plant_and_garden_spares AKA L&S Engineers for just £13 inc. I imagine they would be able to supply appropriately sized engine mounts as well.

Cheers guys!

Can even measure mine now to see if they have drooped..

Just checked the price for 2 mounts 45IRHD strength rubber £24.57 inc P&P.

Excellent.. So cheaper then. Will reassess mine and go from there.

Just measured my engine mounts @50mm tall.. They have sagged a little though I think. That is still 10mm taller than about though! My manifolds are too close to my chassis, which makes me think the mounts have sagged?! Or I am hoping it isn't build quality on my non OEM manifolds..

[LincsCerb]

Looks like there's quite a difference in engine mounts dimensions then. The one I bought from Clever Trevor was only 35mm, no wonder I was getting a lot more vibration.
I have since changed them both for a pair from Av industrial and they absorb more vibration and transmit less noise which is good.

[Jhonno]

So it seems.. May have to go for the 55's or 60's for mine.

[LincsCerb]

Have you got enough clearance at the top between the bonnet and air boxes, throttle pots etc.

[Jhonno]

Well.. They currently don't hit..

[Mad Mark]

Interesting as mine does hit at the top so I might have to look into getting slightly lower ones. Not sure the height of mine at present.
what were the ones you got from Av industrial?

[LincsCerb]

M12x37 75mm x 40mm 45IRHD rubber strength.

Has anyone ever tried fitting hydraulic mounts?

This would be interesting to do after driving a friends M3 with original engine mounts and then driving it with hydraulic mounts that held the engine better but also absorbed more vibration, the handling was noticeably better. The question is though does the engine move much in a Cerb or are the standard mounts good enough?

[ukkid35]

Joolz kindly explained that the reason the high pressure oil line was routed behind the sump on later models was because some early cars had suffered oil line failure when the line became crushed through contact with the anti-roll bar

I will definitely be replacing the engine mounts, as I assume my old mounts may have sagged with age

I will definitely not consider fitting hydraulic mounts as when they fail the engine would drop by 15mm or so

£26 for a pair inc p&p seems fair
