i'm having to skim my cossie flywheel again,

As the Helix paddle has eaten it.

Before its last skim it was 27.6mm (with out starter gear)
Then i had it ground to 26.4mm.
and looks like its gonna have another 1.6 - 2.0mm off again.
Which means it will be 24.4mm



Whats the as 'New' flywheel thickness,
and the minimium they can be ran at?

WD Pro

Cant help you on min thickness sorry but the guy that did mine warned about going to thin as it wont disipate the clutch heat well and could warp.

He also mentioned the heat issues were worse with a padal clutch.

Anyone else?

Fiecos Dan

if you could tell me where to measure i have a brand new one here which is not being used so could measure for you

Fiecos Dan

i measured the deepth,

from the face (where clutch bolts on)
To the step on the back.



But the starter gear needs to be removed if using verniers.


does that sound clear?

i carnt remove the starter gear though

thought it was going to be simple witha tape measure

Fiecos Dan

Can be measured with starter gear fitted, but do need verniers.

I will check mine - but I dont know if mines good or bad

bud-weis

is it a 4wd flywheel or 2wd? i know of a few cars that have had 4wd ones machined to be the same as 2wd....but i can't remember if that is just taking meat out of the back, or from the face ( i'd imagine from the back )

WD Pro

Mine started life as a 2wd (I think) but had most of the 'donut' removed to look like this :

Fiecos Dan

mines a 4wd escos item.


my brother found a old 2wd flywheel , will measure it in minute when i go into garage.

i havnt got a vernier to measure it mate

thsi is a big turbo flywheel i have by the way

Fiecos Dan

Yeah thats the same as mine.

the other way, is to measure from the ring gear to the clutch face?

and i'll measure mine, that way we will know from the two, how thick a std escos flywheel is, and how much mines been skimmed.

Fiecos Dan

Just measured a 2wd flywheel.

and thats 27.57 - 27.68 thickness, which is the same as my escos one was before i got it skimmed.


so i'm 98% sure 27.6 mm is new std thickness.

Do you get that fly cut or done on a lathe ?

Is there any benefits from having it done either way ?

I have a couple of spares if your stuck.

ill measure mine tomorrow for you

it wont be perfect as i dont have a vernier so a tape measurment will have to do



but will give youa rough idea

Fiecos Dan

Cheers.


i get them lathe'd, takes longer, as it takes w while to cut thro the harderened spots, i usually grind the harderned area's out,.

surface grinding is faster,easier and better if it isn't lathe'd correctly.

hello mate sorry for the late reply

mine measures roughly 26 or 27mm from back of ring gear to face of flywheel

this was tape measure measurments

if you need a flywheel this one is for sale aswell

Fiecos Dan

Cheers,


i dont need one, but a mate does, how much do you want, did you say its new, unused?

xr4x4rs

iTrader: (5)

Fiecos Dan

no worries mate

Hi,

Its 25.15mm thick and weighs 6.29 Kg (complete with ring gear).

Note the thickness is from the back of the ring gear which is now flush with the flywheel face.

Cheers,
