Thread: LT95 gearbox noise

on some engines yes, this usually means that either a spring is starting to get weak inside the governor or as the engine heats up its running correctly as compression returns. If you have a whitish smoke coming out the exhaust after about a minute of idling then you are starting to run out of compression

why would you warm it up?

Start it, once the oil pressure light is out and the idle is close to stable (as in not hunting after startup) get in in gear and get it working...

'Cause it rattles around terribly when cold at idle (cold idle is quite a bit lower than warm idle).

At our place, it's start car; drive 30m to front gate; get out to close gate; drive off. Hand throttle is good to keep idle respectable until it warms up.

thats entirely different to "letting an engine warm up" which is how your post it open to being interpreted.

VERY relieved to find this thread, as my recently acquired County has precisely the same noise at idle with foot off the clutch, also strikes me as being a very slow idle rpm presently so I shall follow the advice and increase. Only other thing to add is that the box is definitely more noisy 1st through to 3rd and then 4th is quiet, I was starting to get concerned by this - should I be??????? I am an LT95 virgin, having owned in the region of 40 Landies previously, but all sII and III :-)

Can you describe the extra noise that you're hearing in 1-3?
4th is a direct drive from the input to output shaft, so no load on the layshaft or other gears, and less load on the main input bearing.
Plenty of people on here with more LT95 experience than I have though...

Cheers Steve, yes lay shaft bearings is what concerns me! It's a little difficult to describe, but I guess I am just aware of an increased note that is definitely NOT engine derived, I wanted to say it sounds like a 'spinning up' noise but it isn't quite that! A light whirring I guess!

From my experience, input bearing.
