Trouble fitting 2wd diff mount?!
 

Tried to put one of these on my 2wd Saff after fitting a new CWP and ATB in my diff, and it doesn't fit!

I had to take out the alloy washer and trim back the stainless sleeves, and with only a gnat's clearance, it still rubs on my ARB on the overrun!

As the original was a waste of space, what do I do now?!

GGR has very kindly offered to take it back as I can't use it, the vibration is driving me bloody mad!!

Anyone else had the same issue on their car?

They showed me a pic of one they fitted today, and it fitted perfectly! After 10 years tucked away, I just want to drive the bloody thing!!

Thanks fella

you have to use cap head bolts as for some stupid reason the people who sell these mounts sell them with bolts that done fit! then try selling you a fush fit bolt set? lol i got my stainless 8.8 cap heads from hampshire bolt and tool for about 3 pounds

Is that what it's all about then?!

Why do that?! I thought I was going mad and that the beam had moved or something!! Did yours run really close then? The Msport developments one has nice flush cap head bolts I think?

Where did yours come from fella?

Thanks for the reply dude

Weeksy

mines an r and b one there still very close but dont touch there was no way it would go in with normal headed bolts!

Mine didn't, to the point I had to tweak it slightly, and it still rubs.

Going to send it back!

try cap heads there a little less than half the width of normal bolts mine are in with spring washers too

what rear roll bar are you using? if its got the larger escort rollbar then you will need a mount with countersunk bolts like msd sells

my msd one knocks liike fuck and does my head in, too lazy to change the bolts i ll get round to it soon

NO knocks or fitting probs on mine, even with 22mm arb AND my tow bar brackets around the same area, std bolts used as well.

Hi fellas, how can some ( like mine and bad boy rs) knock and vibrate and others not even be close?!

I am running a STD arb for gods sake!!

Answer this, would you at any point machine the mounting lugs on the rear cover to get these things to fit? Or is that absolutely barking?

Please be brutally honest, I just want to get in this thing and enjoy the drive! Not asking too much is it?!

Thanks for your comments fellas

Weeksy

All you need to do is use the countersunk bolts and plate they're fine then

So MSD one then j1mbo?

Speak to mike rain bird he will sort you the plate and bolts :D

He does the welded variety of mount doesn't he? And lists the slimline kit extra?

Does the NSF one not have countersunk plates and bolts then dude?

I have to take my hat off to ggr here though, they have been really helpful with all this- so frustrating when the one in their workshop fitted perfectly with loads of room to spare...

Why couldn't mine :-(

the only reason tabs one fits is because he is still useing a standard one with the voids iver side filled with polly! just get some cap head allen key or torx bolts mate job done :grin: p.s my r and b one is welded too and a welded properly one is just as strong as a non welded one!

Tbh I'm not too sure give him a ring he's a helpful old boy!

Yeah Graham goode guys are good :D

The Diff Mount clearance issue is a wierd one actually, if you measure a collection of diff to roll bar clearances there is about 3mm discrepancy between different cars. very odd indeed.

Our new mount (available here) solves the issues with every car and fits perfectly:

In fact, here is a video I made showing the flex in a standard one...

And the new one fitted:

WRONG, I'm now on a mc2racing one for e merkur, the reason my poly mount doesn't touch, or even come close even with the tow bar u shaped bracketery there is my 22mm ADJUSTABLE arb is custom made, ON THE CAR, at a grand total cost of £80, I'll be fitting another std type one with filled voids, as trying out a different poly mix later in the year.
The arb was custom made out of the correct sprung steel, I seem to remember it was ENT40, but not certain.

Dident no you had changed from the other one :grin: but there is no drama fitting the other tyes with right bolts! mine went straight in

GGR sent me a pic of theirs fitted complete and it had at least 5mm clearance. with the sandwich plates removed and the sleeves turned down, mine still rubs, and that is the equivalent of 6mm narrower!

I wished the discrepancy was only 3mm Stu!

Easiest solution is just buy one that fits I reckon. If you click buy it now on one of mine I will throw in Saturday delivery for free. :)

Hi Stu,

That's a grerat offer, and much appreciated, but I am 150 quid down the line with my GGR one, and another 120 quid is going to make it one expensive mount!

I am going to machine the mounting lugs a few mm, and put all this aggro behind me , literally haha

Thanks

Sorry mate, I thought you said GGR would refund you in full for it, my mistake.

Good luck, once its sorted I am sure it will provide the improvement you have been hoping for.

Not your mistake fella, but not going to send it back, I can't be bothered (and feel ashamed to, it has had a pry bar on it in places and looks a little sorry for itself!

They are sending me the bits I need to replace the parts I have 'adjusted', so will tweak the mounting lugs, and get it on there, vibe free.

Still waiting for a response from you you regarding mapping my daily runner Stu, been ages fella!

Thanks

Weeksy

Sorry mate, you have lost me with this bit? :oops:

I sent you a mail at work asking if you could help with a map for my modded 2 litre zetec Escort man, but didn't hear back.

Doesn't matter dude, don't worry.

Appreciate the offer on the mount Mr, very good of you

Fire it over again mate, it hasnt arrived with me.
Send it to me personally on sales@motorsport-developments.co.uk

Depending on where you are willing to travel to, you could have a 22mm adjustable arb made so your existing one fits perfectly with zero rubbing, and still have cash in your pocket.

I have replied to the post you put in the Q&A section, and also added a few pics of what I needed to do to clear the ARB with the GGR Diff mount if that helps.

May sound a silly question but I'm new to the cosworth scene and rwd for that matter would you know if your rear diff mount was worn by driving or not also would having it solid like in the pics put major strain anywhere eles on the car/diff or am I a complete retard also is this for 2wd or 4wd saph and how hard are they to fit as I will try have a look at mine tomorrow

I had the same problem when fitting an uprated mount a few years ago before the flush bolt kits were available. I just trimmed a couple of mill off the diff cover, the holes in the mount to the car are elongated anyway so you can then move the complere mount forward a little .

Hi

I had the same problems but got it solved by using a slimline rear plate which eliminates the hex head bolts and instead uses countersunk bolts which sit flush with the rear plate and gives you the necessary clearance.... got the parts from a guy called "silvercos" :-)

how much did that lot cost lol 2 cap head bolts are about 3 pounds :grin:

I just have :top:

hi ... I think it was £8 + pp ;-)

Just fitted my MSD mount, no problem with clearance on mine with a bigger roll bar fitted also.
