Hi all,

Apparently, there is a mounting which can be changed to give a smoother gear change with the auto transmission.

Does anybody know anything about it please?

MN190 · Posted 28 Jul 2012, 08:54 #2

It could be the lower engine mount that is being referred to

Apart from the lower engine mount mentioned above (sometimes called the teardrop) it's a new one on me.

raistlin · Posted 28 Jul 2012, 13:59 #4

Yes, I've checked and it is the lower engine mount chaps. Is it easy to replace? Nano-meet job perhaps?

Where's the best place to get them please? Any conclusive tests to confirm suspicions?

Sit in the car with the bonnet open, with engine running and foot on the brake, select drive and watch engine movement. Select reverse and again watch engine movement, select drive again. Repeat process so you get a good idea. The more movement you have the more wear you have on the mount

Nano? Yup. up on the ramps, undertray off and there it is, two bolts

Only done the KV6 petrol but hopefully very similar

Thanks Dave

Where to get them anybody?

Thanks chaps

I'm surprised VeeKay's has worn out. She's only done 125 000 miles

Duncan · Posted 28 Jul 2012, 15:54 #10

How have people found the powerflex bushes? They don't have the void like the OE bushes, but then I guess the material is more compliant.

One of the engine / gearbox combinations is a little trickier with one fixing hard to get at, though no idea which.

That's one ordered from fleabay at a very reasonable Ã‚Â£23.94 including delivery

Would anybody be able to assist fitting it at the nano-meet please?

MN190 · Posted 28 Jul 2012, 16:55 #13

I have a spare mounting if you need it just needs a new large bush fitting. As long as you can let me have your old one back in return.

Ooops. Does it need another mounting Mark? I don't know much about mechanical things

MN190 · Posted 28 Jul 2012, 19:54 #15

Its the same mounting and has two bushes a small one and a large one. Its the large one that wears on all models and needs changing. It's the strength/flexibility of these that are different between the different models. Normally you have to remove your mounting replace the large bush and refit it.I think there is a how to on here. If you have a spare mounting you can replace the bush first and then it's a straight forward remove old mounting and replace with the one with a new bush.

Its the the V6 as the exhaust downpipe is in the way especially on the 190.
A large bar or similar can be used to encourage the engine to move to one side to assist with removal of the bolt
On the diesel its straightforward

Duncan · Posted 29 Jul 2012, 09:18 #18

Ah, that would make sense. Must have done mine when the exhaust was off, and that's why I didn't remember!

Aye, that will be me

We just need to borrow Artic's ramps.

Thanks Dave. I appreciate that mate

Well... Steve (Arctic) just turned up on my doorstep during a cloudburst and, less than an hour later, the job was done

and some replacement bolts for the undertray... and some replacement viton rings for the coolant reservoir cap.

Cheers Steve

By god does it make a difference. Magic carpet is back again. The deterioration was insidious and so I hadn't realised how off-form VeeKay was.
