Mine seems quite flexible too.

Looking at the pic below, if I hold the thread on the right steady in one hand, I can tilt the other thread off axis very easily with the other hand. Should they be that flexible? The engine is going to put a lot more force on it than I can.

Here's what the insides look like - https://the75andztclub.co.uk/forum/s...d.php?t=257034

Here's me shaking my hydramount

Do NOT get aroused by it!

Ah, but you seem to be shaking it in private ;).

Video comes up as "private" and can't be viewed.

Force of habit Cliff. Shaking it in private!

Ahh - let me see what I can do to share it . . .

. . . try now. I won't spoil the plot by telling you the ending.

That's exactly what mine sounds like. The question is, should there be any air in there at all, or should they be completely full of liquid.

I fitted a new mount just this week and there was no 'sloshing' from the new one.
The only way I could move the top stud out of line to the bottom stud was if I put it in a thread clamp in the vice. Could not be moved by hand.


In fact the one I took off was just as stiff :eek:, but did slosh.


I don't think there should be any air inside, air is far more compressible than the liquid, hence more easily compressed, less stiff:getmecoat:

Much better :}.

Re the sloshing, don't know it it's any help, but when I had my KV6 rebuilt a few weeks back, the hydramount was taken out to aid some painting, and it made no sloshing sound at all.

Cliff

Oh!

The plot thickens.

I can push mine (hydramount, thanks) a few degree off line by hand. May appear in the sequel movie.

Anyone fitted a sloshy one and been satisfied with the result?

Here's a question for anyone:

If there is an air gap inside, what purpose does the liquid server?


.

Here's what I'm doing to test the axis tilt (or lack of it).

Grab the LH thread (as pic below) in left hand and hold it steady. Press thumb of right hand on curved rubber section on the RH side and use the other four fingers to lever the RH thread. Using this method I can push mine a good 3/4" off axis, measured at outer end of RH thread. That's a very big difference to Stephen's mount, which needs a vice to be able to move it at all.

It does seem logical that the more air that's trapped inside the more easily it will twist off axis.

Good question.
