Flywheel
« on: September 01, 2004, 04:48:44 AM »
Do the 8 and 16 valve 1.6's ust the same flywheel?  I ask because I just put a new clutch in my 8v and I want to put it in my 16V but I think the 16V is a California (bigger clutch).

Thanks

The parts books that I have seen list a different part no for 8Vs and 16Vs.

That would make sence because the clutches are different.  But will it bolt up?  Are they ballanced differently?  Those are my big questions.

 beleive the only difference between the 8v and 16v flywheel is the depth, the 16v is thicker, but not by much. The clutch is interchangeable.

So the 8V flywheel is thinner? does that mean its also lighter?

According to the Hollander interchange the flywheels swap....

     From looking I have found there are thicker and thinner flywheels on both 8 valves and 16 valves so I assume they tried running changes during production.
     My parts info shows the 16v clutch is larger (slightly) but will swap with the 8 valve.

Thats the best info I've got.

Thank you for the information. As your probably know the 16V flywheel is very heavy, and combined with the lower gearing, greatly affects 1st and 2nd gear performance.

I have swapped many flywheels and pulleys before, and I can tell already, even with the pulley I have on the X90 now, that the performance is hindered by the over weight flywheel.

I have emailed Fidanza and requested them to considered a proto-type for the 16V engine (I assume it will work with the 8v as well).

If they get back to me, I will let you know.

my 16 valve engine in my samurai has a samurai flywheel on it with a samurai sized clutch and I believe that it is 15 pounds lighter than the stock flywheel,I have an adapter plate between the engine and trans though so not sure if you could run one with out it for the starter to fit correctly?

Hey BV1

     Why not just pick up a used flywheel and have it machined down? There is a pile of weight that can be safely removed by a good performance machine shop and it's a bunch cheaper than a custom flywheel.

Zaggy's research is correct. The 16V and 8V use the same flywheel and the 4-door Track/Kick's use a slightly larger clutch disc (maybe 1/2" larger in diameter) so anyone could swap in the larger 4-door clutch into their 2-door for more holding power.

Looks like a lightened Sammy flywheel with an insert for the friction material to grip on. Wonder how well that works?
Another idea would be to use a Swift flywheel since they are 11 or so pounds.

From what I seen on the Escudos that I've owned,  there is a 200mm (8") and 215mm (8 9/16") clutch plates available, IIRC they also have different amount of teeth on the starter motor gear depending on what size flywheel you have.

The starter is mounted thru the block, so a
change in the flywheel doesn't affect the starter.

And you can't change the outside Dia. of the flywheel
because the starter will not engage the teeth properly,
at the same time, you cannot change the # of teeth on
the flywheel to a diferent # or the starter would grind on
the missmatched # of teeth, of coarse a Spanish built Zuk
could have a different starter and flywheel combo, at least
teeth wise, say they used a Lucas starter and a flywheel to
match that starter

In any case all the 1.3, 1.6 8V and 16V will bolt to each others
crankshafts, so any flywheel clutch and pressure plate assembly
could be swapped to another.

As far as flywheel weight, a heavier flywheel can make offroad
driving a little easier with an engine that doesn't stall at easily
while you are slipping the clutch on hills, it's the inertia that keeps
engine from stalling as easy.

Just some useless info for you to
consider before doing somthing drastic    ;)
