dmf fault?
hi folks
having just had the gearbox out of my 2002 110 td5 due to gear box layshaft brgs being knacked i also took the oppertunity to change the clutch (didnt seem excessively worn considering age and mileage ) dmf wasnt replaced as it appeared to be ok plus £4-500(I would have to spend a lot of time on my back to earn that amount of money mending trucks that is)
and i also removed the exhaust manifold to drill out the sheared manifold to head studs. now find i have a very worrying noise on acceleration ie a light tinkling rattle under normal driving up to about 30 ish,replaced by a heavy knocking rather like a big-end knock that seems to dissapear when the vehicle get to speed and the load on the engine reducers also the heavy knocking is also present under harsh acceleration,I know there is some distortion of the exhaust manifold but the noise wasnt there when it had a few less studs holding it in place! also a forgot to add I also uprated the transfer box to 1.22 ratio

any ideas? all imput greatly received

cheers kevin
p.s iv'e tried revving the nuts of it whilst stationary and also driving it thru the gears with the transfer box in nuetral and all sounds normal

having spent the weekend away with the landrover club off-roading at newark the knocking noise seems to be getting worst
but nothing as failed yet,still thinking its the DMF so now the question is do i replace the dmf or fit a solid conversion (smf)
i know the topic as been raised before but what are the negative issues of fitting a smf???


cheers kevin

Can I ask what symptoms your gearbox was showing and what milage it had done? I currently have a thread going in the maintenance and modifications section as I have gearbox woes. 2002 110 td5

Hi jimb

The symptoms were a heavy rattling rumble whilst driving thru the gears apart from 4th gear ,also it was present in overrun!
Initial diagnosis was a missing gear tooth on the lay shaft,but turned out to be very badly worn layshaft bearing,almost to the point of breaking up
The mileage is 107000

Hope this helps
Kevin

Sadly as we do quite a lot of these, many clutches outlive the flywheels. Did you check for play?

update time

turns out it wasn't the dmf after all (yes it was checked for wear but i decided it was servicable)
the heavy frightening knocking noise was caused by the x brake hand brake conversion (more specifically the britpart handbrake cable supplied free with the x brake when purchased from paddocks), so the moral of the story is allthough i saved £24 onthe cost of a cable it could have cost me a lot more if i had jumped the gun and took the gearbox back out!


cheers kevin

My R380 mainshaft bearings gave out at 22,000 miles. Just out of warranty.
Got an Ashcroft recon exchange which is great.
