#1: Engine mount BIG problem Author: gpvecchi, Location: ItalyPosted: Wed Nov 30, 2011 2:30 pm ---- Passenger side engine support is practically a block of gum with a bolt that is screwed to a nut welded to chassis.
Now, my problem is that nut is no more welded! I replaced it with a "blocked" one, but engine movement makes it always loosen...
Anyone had this problem and managed to solve it?
Thank a lot!

#3: Re: Engine mount BIG problem Author: macca1411, Location: Westhoughton, LancashirePosted: Wed Nov 30, 2011 2:38 pm ---- Have you tried using an anti shake washer under the nut?
#4: Re: Engine mount BIG problem Author: Seabook, Posted: Wed Nov 30, 2011 3:08 pm ---- liquid thread lock.
anti shake washer won't handle that kind of force
#5: Re: Engine mount BIG problem Author: macj, Location: EssexPosted: Wed Nov 30, 2011 3:44 pm ---- weld a plate over the captive nut with a hole drilled in it.... This stops it turning.... I have just done this mod

Thread lock is useless, better of with a Nordlock washer, they never come loose
#7: Re: Engine mount BIG problem Author: gpvecchi, Location: ItalyPosted: Thu Dec 01, 2011 2:34 pm ---- Thread lock and washer are useless, I already tried... I'll try macj suggestion, thank you (as usual...)
I'll post results...
#8: Re: Engine mount BIG problem Author: gpvecchi, Location: ItalyPosted: Fri Dec 02, 2011 2:24 pm ---- @macj, do you remember the dimension of the plate you used? Thanks!
#9: Re: Engine mount BIG problem Author: macj, Location: EssexPosted: Fri Dec 02, 2011 2:52 pm ---- 40mm square with 14mm hole in the centre
#10: Re: Engine mount BIG problem Author: MrBSI, Location: What's it to you? ? ?Posted: Fri Dec 02, 2011 2:54 pm ---- macj do you have any issues with nuts / bolts coming loose even with threadlock applied?

Yes mate... The two ARB bolts on the rear radius arms, the rear damper bolts. We spanner check before each event now. The engine mount ripped the captive out of the chassis but with the 16swg plate over it there seems to be no further issue

Might be worth looking in to some Nordlock washers, there fitted to a lot of forklifts.

You might damage the paintwork as you tighten them up while fitting.

Can't see it doing any more damage than a standard flat washer.
Never heard of them before but look a lot better than the spring washers I'm used to using.

#21: Re: Engine mount BIG problem Author: gpvecchi, Location: ItalyPosted: Sun Dec 04, 2011 8:02 am ---- Thanks, macj, next week I'll prepare the plate and I'll test it...
#22: Re: Engine mount BIG problem Author: macj, Location: EssexPosted: Sun Dec 04, 2011 8:06 am ---- You need to weld it in place. I clamped it in place with a bolt and washer to make sure it was aligned correctly, cover everything with a fire-proof blanket to avoid sparks getting in bad places. I would suggest fully welding it in place noce the captive nut is fixed. you can then paint it with a protective coat or two before refitting the mount
#23: Re: Engine mount BIG problem Author: gpvecchi, Location: ItalyPosted: Sun Dec 04, 2011 8:15 am ---- Oh, did you weld it to the chassis? I thougt that you just screwed the mount on it... I think it's just too difficult for my acknowledgment...
#24: Re: Engine mount BIG problem Author: macj, Location: EssexPosted: Sun Dec 04, 2011 8:22 am ---- You could bolt it in place with the mount..... but fit a self tapping screw in one corner to prevent it turning
#25: Re: Engine mount BIG problem Author: gpvecchi, Location: ItalyPosted: Mon Mar 19, 2012 3:07 pm ---- It seems I finally fixed it! I used an auto-locking nut (the one with a plastic ring) and a big "conical" washer (I don't know the right tech term) screwing the engine mount at about 20kgm instead of 2kgm as garage manual says...
