Had the clutch go on the 110 last week ... cest la vie,
This is the second time that the clutch has been replaced since I've owned the vehicle (it was 15 months old when I bought it) The first clutch was replaced at a SW main dealers and the mechanic reported to me that a lot of the bolts had been over tightened and some bolts were cross threaded - so it took longer to complete the work as he had to drill out and re-tap the holes This week at another main dealer doing the same job 4 years later, the mechanic said that all the bolts were over tightened & cross threaded and needed to be re-tapped etc ... which put extra time on the job 
so what is going on here ...? is this a common problem and landrover service manual have put the torque settings to high for the bolts ..? or is it a simple way to add a few notes to the bill ? any thoughts?

Probably the latter. You can only tap new threads as long as there is sufficient metal left unless you fit oversize bolts or drill and tap out and fit helicoils of the original size. If it is a known problem helicoils would be the way to go. Difficult to gauge unless they did tap out originally and due to reduced material remaining the same bolts stripped again?
I would ask what did they drill the holes out to and if they've fitted oversize bolts or helicoiled them? If you go through life with your head in the sand....all people will see is an ar5e!! Treat every day as if it is your last....one day you will be right!! |

from what my partner told me the bill says they helicoiled the holes ...
but that was what the first mechanic had supposed to have done .....!  Poppy - TDCI (Puma) 110XS 2.2 - Camper conversion - see the build here - https://www.defender2.net/forum/topic56530.html

He might not have helicoiled all the holes.

I agree with Sockpuppet.
Helicoils are a damn good repair and I think it unlikely that the stripped threads encountered would have been the historical helicoiled ones unless a great deal of excessive force was applied to them. If it were me doing the job and my Defender I think I would have helicoiled the lot to prevent further issues, but then again I do have mild OCD.
