Engine vibration

[knuts2au]

No that i've got the D2 TD5 back together and able to road test, i have a vibration/resonance at about 2,200RPM, does it in all gears while accelerating but not when power off/slowing down, pretty broad when driving but free revving noticeable just over 2,000RPM. Just fitted new crankpulley, but was there before it was replaced.
Seems to engine related as it's not there when cruising or slowing down, hard to describe, more like a harshness more than a vibration.
Anyone come across something like this before?

Check front propshaft?

There's a bit of a harmonic at about 2,200 rpm with the TD5 that manifests itself in anything that is a bit loose, usually the handbrake shoes. There is an LR Bulletin on that fix but sometimes just an adjustment can sort that a bit. Does it go away in 4th lockup?

Engine mounts ?

Sorry for thread hijack but my Td5 has that grindy feel which goes away goes away in 4th lockup - any idea what it is??

Hi Charlie,

To check if it is the handbrake rattle just ease on the handbrake a little when you have the rattle at 2,200 and it should go away if that is the problem. However I don't like the sound of "grindy feel" maybe it is a trans problem.

Mine has a nasty vibration to it as well but it's only at a dead stop. It's a tad worse in gear than in P or N. I'm like 80% sure it's mounts though. Smooth as silk during revs and moving...

There are LOTS of posts about TD5 vibrations,,
cheaper to spend an hour on here searching than just start replacing parts,
Though the front propshaft is always a good place to start.

The engine mount vibration a is near continuous rumble, made me feel like clenching my teeth together. It was so good and quiet after we changed the mounts.

After going thru 39 pages of posts on the ultimate fix for vibrations there doesn't seem to be a fix, people have changed every conceivable component, or added snake oil, without solving the problem. Seems to be an inherent TD5/auto resonance at a particular rev range around 2,200.
I think i'll just turn the music up and stay above that rev range.
