Changing top left gearbox mount, guide?

[Paddy_g46]

Has anyone got, or can write me a mini guide to changing the mount under the battery?

Thanks

Whole mount assembly or just the rubber part inside it?

 

[Cupman29]

From memory:
Remove battery
Remove airbox and inlet pipe
Remove ecu bracket
Take the weight of the gearbox with a trolley jack
Disconnect loom from mount
Remove 3 17mm bolts holding mount to gearbox
Remove 4 13mm bolts holding mount to chassis
Pull the mount free from the bay
Unbolt upper and lower parts of the mount and replace.
Reassemble in reverse

May have missed something but you should be able to work it out. Hope this helps.

As above is pretty much spot on and it'll all be pretty obvious once battery and airbox is out of the way.

Just the rubber inside mate.

Cheers mate, doesnt sound too bad! So basically i need to remove the whole battery tray mount thingy to change the rubber?

 

[Cupman29]

It's easier to take the whole thing out IMO as you need to hold the nut under the mount to free the top rubber. Also means you can ensure it's all torqued up correctly.

Not too much work to remove complete mount.

 

[Paddy_g46]

HELP! The main bolt that goes through the rubber has sheared off! What can i do?!

 

[Cupman29]

TAKE THE MOUNT COMPLETLY OUT!

Thought I'd mentioned that earlier?

 

[Paddy_g46]

Ok, im removed the gearbox bracket thing that the bolt goes through and luckily have it out but now i need a new bolt and this thing looks pretty meaty, doubt ill find 1 to match it anywhere!

Yeah but the bolt was sheared from the start, i thought the rubber just needed replacing! Just came across it as i was taking it all apart.

f**k! My renault doesnt open on a satuday! Im screwed, need my car for work!

 

[Fred@BTM]

drive without it, you already have been!

 

[Paddy_g46]

Lol, i only drove him home from work after it popped at lunchtime yesterday, iv id realised how bad it was i probably wouldnt have taken the risk!

 

[Paddy_g46]

How is the bolt meant to come out of the rubber mount? Is it screwed in or just pushed through?

 

[Fred@BTM]

its not going to go anywhere, just the box will be sat on the subframe, will make a bit of a noise, just don't gun it

 

[Fred@BTM]

kinda pressed in, it has splines so when you tigthen it up is "cuts" into the mount

 

[Paddy_g46]

Got it out. Right so do i meed to replace this entire "assembley" or is this bolt more than 1 part? .


Also, i dont suppose anyone could please dig me up a part number?

 

[Paddy_g46]

if anyone can help me out with a bolt this weekend then PLEASE get in contact! I would be eternally grateful!

 

[Paddy_g46]

Forum members FTW! Someone came to my rescue this afternoon so the car is back on the road and driving a lot tighter than it ever was before!

 

[Cupman29]

Glad you're sorted mate! :clap:

 

[RedBeast]

did anyone find out what that bolt is called the same thing has happened to me?

 

[AlexW]

Pay membership and talk to Adam at renault Wolverhampton, or speak to your local renault dealer, they'll be able to find it easily.

 

[Michel5]

does anyone know where is installed the inferior gearbox mount

Epic thread revival but does anyone have any tips on how to seperate these two parts before I go at it? I really don't want to damage the big bolt. Thanks!

Changed my gearbox mount recently and had issues getting the mount off the big bolt. I left the actually cast mount that connects the box to the chassis in place and just changed the rubber mount in-situ. Was a bit fiddly but definitely achievable.

- using a trolly Jack, Jack the box just enough to support it and take the pressure off the mount.

- take the 3 x nuts off the rubber mount itself (2 that hold it to the cast mount and the one that bolts to the central gearbox bolt)

- using a pair of waterpump pliers, grip the rubber mount at the 9 & 3 positions and give it a good wiggle and pull upwards and it should pop off. You’re trying to break the stiction/any corrosion between the hole of the mount and the splined part of the central gearbox bolt.

hope this help.

I ended up removing the whole spider assembly. As I then had the mount out I just put it in a vice and went to town with a hacksaw and stanley knife. When I could get a grip on the metal part it was easy to loosen off the splines. Had a nightmare getting everything to line up when putting it back together though haha.

Now I know how it all goes together and how the mount is made I would probably do it differently next time!

Part way through this job. Got the battery bracket undone but struggling to get access to the gearbox bracket bolts. Is there a trick to it?

I did mine last week and didn't bother removing the bracket. Just the three nuts on the actual mount. Just watch out because the bolts on each end aren't captive and will fall out if you dont hold them from underneath... Ask me how I know

 

[172CupHGA]

Thanks - I think I need to get the entire mount off though, as I am replacing both parts of the bush with a vibratechnics one. At least that's what others have said...

 

[TheBandit]

As @Steve1986 says no need to remove it. But any questions fire away.

 

[172CupHGA]

I see. So the mount sits only on top of the mount? Nothing goes underneath?

How do I remove the existing bush off the spindle?

 

[172CupHGA]

EDIT: so the vibratechnics bush sits only on top of the mounting bracket - no part of it sits underneath as well?

 

[TheBandit]

Everything should be able to go in through the top.

In an ideal world you support the gearbox with a jack, remove the big nut, release the jack and the spindle should drop out.

Failing that you may need a hammer to knock the spindle out.

In my case I did replace the spindle as the seller included one with my mount that was in better condition - but best not to open that can of worms if you don't have too.

 

[TheBandit]

*the two smaller bolts come out the bottom but you don't need to remove the mount to access those

Struggling to get the old bush off the spindle...

Lower any support you have and whack the central stud using a long extension bar. The stud is splined so it grips the mount a bit.
