Technical 1242cc Inlet Manifold

[rallycinq]

Hang on a mo!! Are we now claiming the 1275 Metro as the paragon of smoothness

Seriously, has anyone had an 1108 balanced. I am desperate to get mine into the car to see what the difference is.

Cheers

It's like when you've got a mouth organ in each hand, then you're harmonically balanced.

[arc]

Crankshafts vibrate with a twisting motion due the torque variation that results as each cylinder fires. This vibration is at its worst at some critical RPM. On a V8, this RPM is typically in the 4-5000 RPM range. If you operate the engine at this critical RPM without a harmonic balancer excessive vibration will eventually BREAK THE CRANKSHAFT. DON'T LEAVE IT OFF.

A harmonic balancer modifies the vibration characteristics of the crankshaft and flywheel assembly. They are made from of a heavy steel ring mounted over a thin layer of rubber on the outside of a center hub. The rubber acts as a spring. The ring twists on the rubber to cancel out crankshaft torsional vibration. Some energy is removed as heat in the rubber but the balancer's primary function is to store energy and return it to the crankshaft at just the right time to suppress vibration.

So is it the bit that the alternator belt goes over?

What does this bugger look like...im getting frightened that I may of missed it off when putting the Alternator pulley back on, or is it inside the engine??

Yup, its like a big fat crank pulley, on the outside of the engine at the opposite end from the flywheel. As far as I know its a standard fitting on 1242 engines, its been on all the ones I've looked at.

Oh, so its nigh on impossible to leave it off on a FIRE unit then...

Good!
Would it mater that im using mine off the 1108cc Engine due to a rather nice chunk being taken out of the original one?
