Subject: Re: Uneveness/vibration
Morning Bill,
Difficult question. You seem to have checked all the usual suspects but there is one more. The later LG45s had a funny spring damper in the front engine mounts, if this is not wound up tight it can cause what you describe.
However if your vibes are from about 2400 to 2600 revs I would suspect engine harmonics and a possibility of worn main bearings although the LG45 does not suffer anything like as much as the earlier Invictas and M45s.
If not the front mounts then perhaps give me a phone and we can talk through the symptoms better and try to solve this.
Best regards,
Julian
