Definitive 250 gearbox mount solution?

I take it this is the mount that has the piss weak bolt underneath the battery ? If so, I'm surprised mine hasn't broken yet !

 

Id appreciate this information too, as I'm still running the original bolt.

 

Nice one Dale - thank you.

Thread should probably now be moved to the guides section.

 

So the 275 mount is better than a 250 mount, but still not good enough, and thus you need to upgrade the bolt, or how are we to interpret that?

thanks...

 

Nice one Dale, I am planning on doing this at the weekend so this is a great help.

 

I haven't had this part fail yet. What am I doing wrong ? hahaha

 

Don't jinx it but me either haha
(touch wood)

 

I do agree dale and it is a very informative thread and will be very useful for present and future owners
And it is what the site needs ;new informative info about our cars no doubt owners Google what's wrong and how to fix their pride and joy and no doubt I will at some point after all that's why we are all here to learn about our cars while chatting in between
Good work

 

Makes sense.. Any chance I could persuade you to post the part number? The 275 is not available in Denmark, so can't look it up using a registration number.. Thanks..

 

Why replace the existing mount, simply remove, retap the bolt hole to a larger diameter bolt and replace

 

I picked up this beasty, m12x1.5, 50mm 12.9 grade, should do the job. Now wheres my tap and die kit gone...

 

Resurrecting this thread.. Which parts do I need to do this job ?

Did you replace the full mount or just the bolt durmz?

 

How much are the parts, Jamie? Is it a DIY job?

 

I did. £70. How did I miss that?

 

Where did you chaps get the bolts from?

 

I'm hoping this is the cause of my issues will be looking later.

Would cause most of the symptons I guess. But my heart still thinks flywheel. Just not had a chance to look since Saturday but if this has failed I guess it'll be sheared bolt most likely.

I've not got an air box as running a filter so assuming battery out and should have access

 

How come you decided to change the mount itself if you'd already added an uprated bolt? I've just replaced the bolt on my mount, wondering now if I should have done the mount too.

 

Possibly could of seen it but figured I'd do the mod anyway and it would need to come out, took about 15 mins to remove all the bits.

Bolt had sheered off and gearbox had dropped and moved forward, surprised I had no selector issues with the gears.

Only issue now is I drove about 40 miles back like that assuming it was flywheel on Saturday.

I'm going to drill out the bolt tonight thats stuck in, tap and thread to house a new grade 12.9 bolt M12 x 55mm so slightly longer. Will then put it all back together tomorrow morning and give brief visual inspection to the driveshaft and take it for a run.

No vibrations through steering wheel and happy days, vibration and guessing I'll have marked the driveshaft in which case I've just seen it's £338 from Renault for OEM or £136 for a aftermarket part and will replace and stick a spacer on at the same time.

Anyone changed driveshaft and if so should I stick with OEM or will aftermarket part be sufficient if I need to replace.

 

Ok plan was to sort this today but yesterday got home the mount bolt was drilled out then it was tapped.

Jacked car up, removed under tray, let car back down jacked gearbox, refitted and hey presto took for a drive and it's spot on again now all sorted so really pleased.

Couldn't find axle stands but then it was around 10.30pm last night and just wanted to crack on before the weekend so can get myself to local beer festival today now without tackling it half cut later or tomorrow.

Lesson learnt! and advise to anyone else. Change the bolt before it goes as it will do as it's to weak the 1 bolt holding it. If had more time I'd probably have revised the mount and had the bolt going through the bottom with a nut at the top that way rather than the risk of the bolt snapping the stress would be on the mount itself which I don't believe would fail.

 

how so on the diy front dude? something I could do with doing

 

I'm changing the bolt on mine tomorrow. I have an M12 x 1.5.

I'm gonna drill it out with a 10.5 mm bit before tapping it out. Does this sound right?

 

has anyone got there old gearbox mount they want shot of ????? and the top part also
