Rattle or Vibration. 4.2 turbo.

Very common mate with the 4.2. Mine harmonics through engine and gearbox and exhaust.

It's just the awesome power of the td42 wanting to get off road rather than the black stuff!

Gear roll over. Gearbox chatter. Whatever you want to call it. Its the sound of the TD42T doing its thing lol!

Haha yeah when you get used to it you grow to love it! Was interested to read exactly what caused it though as I never really knew exactly why they do this.

Does anybody know what the factory original clutch is in the Y61 TD42T?

[drgtr]

All I know is all TD42Ti come with Solid Mass flywheel from factory.
They are big like truck gearboxes so its normal. No ill effect. Most have it and through their life its all good.

Just embarrassing at times haha.

Mine makes this noise as well...
Is there any way at all you can stop it making the noise, by adjusting the harmonics or anything? Would replacing the clutch and all gear oils help at all?
Cheers

Honestly I have read every single thread and post on the internet I can find.
I would say no. Its a normal thing due to the design and nature of the massive gearbox.

there is no detrimental affect at all. Just embarrasing at times but you get use to it lol

What actual components is it that are rattling?

It's called gear rollover. It's the gears themselves meshing under little to no load. Give it some load or rpm and it goes away.

Its strange how this is more prevalent with the TD's. My ZD never had this, even with a SMF. Now with a TD, using all the ZD running gear still, I have this same rattle. But strangely enough, I like it.

It could be due to the odd firing order and shear rotating mass of the TD, but I dont really know.
