Not Using Dowel Pin When Mounting Flywheel?

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. :down:

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?

wow, glad I subscribed to this 10 years ago!

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

 

..and this thread made it to page 2 !

FFS...

    • Hey everyone! I'm new here!  I am a 19 year old tyre fitter at bridgestone. My passion for cars started at a very young age when I was bought a au falcon look-alike go kart.When I was younger about 13 or so I heard a car speeding up the hill past me and all I saw was its rear end. A skyline r33, rear end and ever since that day I've dreamt of owning one!   102,000km 5sp manual top mount a/r 70 turbo
    • i think the general rule of thumb (here in vic at least) in 2 up 1 out, so from the std 16"x6" up to and including 18"x7"  but i could be wrong, ask your local tyre dealer they know the rules , it's their job
    • Worth a shot, but not saying this will be it I had issues with my CAS a long time ago after i disturbed it when I did my timing belt. Spent a long time taking top timing cover off and running, and putting it back on and running Noise went away with it off and CAS mounted, came back when cover was back on with CAS Mounted From memory the spacers were not installed in the gasket or something fun along those lines. Eventually ended up replacing the CAS to as it had a horrible bearing noise It was already suggested above but it would be worthwhile taking the top timing cover off and see if noise goes away
