Not Using Dowel Pin When Mounting Flywheel?

[R32Abuser]

Seems fair, seeing as you have no idea what you're talking about.

Same could be said for yourself judging by a few of your last posts here and elsewhere.

Sounds alot like tha garbage talk you hear over on NS.com. The fact that you feel the need to personally attack someone to get your point across does not add strength to your argument.

No references to back your argument by any chance?

MrStabby has it right.

R32Abuser you need to re-think your mechanical force concepts.

Let me ask you this...

Assume the clutch and flywheel assembly is at rest.

Induce a torque (via the motor) onto this assembly so that it will rotate.

Now, suddenly, the flywheel is instantaneously stopped. Newtons first law states that the clutch asm will want to continue to rotate. We all know that it will cease to move a very short time after the flywheel stops rotating due to these two items being attached to one another.

What part of the flywheel/clutch assembly transfers this torque reversal? Would you agree that it is the locators/fasteners which fasten/locate the clutch assembly to the flywheel?

It has to be...there is nothing else attaching these two indivdual parts together.

Now, if the dowels are toleranced tighter than the bolts themselves, what else will transmit this torque reversal?

Also,

Since this assembly is not counter-weighted, and since another member has stated that locating is not important, then why are the dowels there? I agree that in some setups (aftermarket) there is no dowels, but does that automatically make them a good/better design?

Your very own argument shows that you do not know how the fasteners do their jobs. You had best stop now. You are making yourself look stupid.

No references...? So many credible source must agree with your argument though. Right?

You must be correct though...Nissan (and majority of manufacturers) have done, and continue to do it wrong. You dont need dowels on the flywheel.

I would suggest you all look at the flywheel arrangement of a 1970 Mini Cooper -

I don't have a mini cooper gbox in my garage, care to explain? haha

This is interesting, suggests there is a correct orientation for the flywheel. To which the dowel will assist in getting it right. So as long as you align the dowel holes should be all good, right?

Even better, John Cardogan just this last week did a series of videos on Youtube agreeing 100% with me and 0% with R32Abuser.

I can't believe the numpty you were arguing with couldn't grasp-

1. Dowel is for locating

2. Bolts press two surfaces together
