stock 20v flywheel weight???

[4agte]

aight ive spent an hr or so looking for this info

just curious about what the standard weight of the stock 20v flywheel is and if anyone has a picture of one thatd be awesome

[DeftAnesthetik]

I have a stock flywheel for the 20v that I will be weighing today as a matter of fact. I am curiuos to know as well. i will post some pics of it later today as well. (as long as someone does not beat me to it)

Silvertop is about 7kg, blacktop is about 5.5kg.

Bill is on the money here. +rep for him. In addition Fidanza alloy flys are 3.4kg.

interesting mine weighed in at 5.5kgs it came off a silvertop so maybe its a blacktop one

id still be keen to see some pictures of other peoples

here is mine

Looks like the BT ones ive pulled out. The ST ones tend to have a full edge for mounting lugs from memory.

[4agte]

yup thats what i thought it would be a full edge if it was a stocker ok cool

makes sense why it looks like an oem part then

+rep for everyone thanks for the help well those i can give it to

question tho cause this one dosent have dowells for the clutch do you need something special to mount the cluth or just bolt it on???

[takai]

It has the little holes for the dowels, but i know the occasional mechanic who will remove them after torquing up a clutch because they are paranoid that they will fall out.

You should (i emphasise should) be able to get new dowels for almost nothing from your local clutch specialist. I know Extreme Clutch down here will basically give them to you if you ask for them, and i have about 20 lying around the place.

ahhh sweet no probs ill ask the clutch guy then i was a little worried about that cause i couldnt see any as to how i was going to get the clutch on there thanks heaps mate

[Mr Revhead]

hmmm we recently weighed them and we got some rather different weights.....

black top was 6.0 for the black top
silver top was 6.7kg
fidanza one is listed as 5.5 or so here, though we didnt have one to weigh
TRD is 4.3 and has the advantage of replacable ring gear which a lot of aftermarket ones (ie toda) dont

[takai]

Fidanza have 2 models, a cast steel one with an integral ring gear and friction plate, and a 3 piece alloy one. The 3piece alloy fly is 3.4kg.

[Mr Revhead]

oh yep, thatll explain that.
will look further into the stock flywheels
they were weighed last weekend, but i wasnt there at the time
used electronic scales.
also interesting to note that the TRD clutch cover is about 1kg lighter than stock too

This is what the 3 piece ones look like:

I know we always say, "Don't machine flywheels down, it's BAD."
But the flywheels here appear to be simply a machined version from factory. If the materials were the same and you could check for static balance afterward, I don't see why not to do it.
