Possible clutch damage after towing

[nissannewby]

No mate unsure if there was specific time in which they changed over. I dont really think its model specific either. The larger h260 diff will have the basket type. Its really anyones guess as to whats in it.

There are differences in the later gu lsd. There is yet to be any proof that one is better than the other. You can still get the basket type in gus but its not known until you pull it out. The different type uses clutch packs on the side gears instead of in a basket like the other type.

I would love to see a dismantled one of those LSDs with clutch packs on side gears. I'm guessing they perform better, as there're too finely tuned clutch packs of each axle.

The engine still rotates in the same direction.....

Yes, but the torque required to drive car forward or backwards is different..

That must be 'cos there's only one reverse gear and the torque must be mechanically compromised to be able to find the right balance between speed and power for reversing.

Not exactly. The torsional twist comes from the engine rotation. This happens because the crank is not symmetrical and obviosuly has weight being thrown around. A gearbox has nice straight shafts with near as applicable perfectly round gears.

The only thing that changes is the rotational direction of the output shaft and then obviously the diff.

Not all vehicle diffs aren't symmetrical either... the pinion is offset and the gears helical cut.
This makes the transfer of the torque from the pinion to the crown more efficient with the helix (forward) than against it (reverse).
Thats why mechanical diffs in industry or whatever that need to rotate with equal efficiency and speed in either direction are centre driven and the teeth parallel ground

I'm puzzled about the reason the teeth need to be parallel to the ground.

Lol. Not quite.
He means straight cut, not on an angle like our diffs.

Ok, cool.

What does it mean the "pinion is offset"? and why?
I'm guessing by offset, the evil twin meant the axis of the pinion doesn't necessary go across the axis of the crown wheel?
What is the need for that offset in some diffs?

[dom14]

Just updating. Engine mounts & gearbx mounts are in good nick.
Clutch oil level is good. No oil leaks either.
So, I'm puzzled about the funny smell of clutch grinding.
