Anyone have a 1.6L flywheel laying around they can measure?
 

Curious. Could benefit all of mankind.

Partsgroup dude told me folks modify the 1.6 fly to use with a twin plate clutch. I wanna know if it's possible or plausible.

I need the following dimensions:

crank surface to friction surface, +/-.100" is fine
bolt circle diameter to +/-.030"
outer diameter of friction surface to +/-.030
inner diameter of friction surface to +/-.030

thickness of the flywheel JUST outside the friction surface.. where you'd bolt a clutch to if it didn't have the threaded hole towers. rough dim is fine.

Thanks!

Matt

if I had precision tools I would do it for you on saturday.

what tools do you got?

I have no precision measuring equipment.

so 1/32 is too hard to measure with a ruler?

I don't own a ruler that accurate, but I'll do what I can if the trans gets dropped.

Damn...I just did a 1.6L clutch/flywheel last week...

I may be able to do this, lemme see if I can find my 1.6 stuff.

I had a flywheel laying around all winter you coulda measured :doh:

I think I still have my flywheel sitting in my garage. I will look for it this weekend. If I do, feel free to take it and measure what you need.

Would measurements from a non oem flywheel would suffice?

I guess it depends on what it is. Lets call it "yes if steel"

Yoram: I may take you up on that since you're local.

if anyone else gets it done first, that's cool too.


and I only found out about this like a few days ago!

I have an ACT prolite coming in this weekend if all is well, tell me if you'd need dimensions

bumpity bump bump?

I have one at home....4 hours away from here :)

If I had my caliper I would. I can't find it!...and I have the flywheel sitting here. lol

I've got my 1.6 laying around that I just changed out...not sure if I have anything that accurate to measure with. and not sure what to measure.

Matt I might have one by the end of the week....Picking up a short block, might have it still attached.

I just took my old one out and put in a resurfaced one. If you have the measuring tools we can meet up and you can take what you need. I need to take it back to PBC soon so i can get my exchange $ back soon though

K, got some measurements for u, I was not exactly sure what you needed, but hope it helps.
158mm ID of friction surface
276mm OD of friction surface, however there is 117mm of usable material beyond that until the edge of the disc (not counting the teeth obviously) The pressure plate bolts are less than half of an inch inward of the edge of the flywheel. Also I dont have any way to really measure how thick the metal is at the friction surface

holmes you win the motherfuckin prize! ...after you read thru the recent posts.

I have my original 1.6 flywheel. Let me know if you want to meet and measure it.

this is for a 1.6? hmmm.. seems kinda large for what i was thinking.

thanks tho!

Whelp, I got my used tilton in from ebay and put it on top a spare 1.6 flywheel. The friction surface will need to be machined back about 1cm ish and the entire area outside of the friction surface will need to be milled down so that the step is 0.100" tall. Also the machine shop would need to center the cover on the flywheel and drill/tap holes to mount it.

If you look carefully you will see that the ID of the friction surface is already the perfect diameter for the tilton clutch discs. The discs that came with this used clutch is a 3 plate sintered metallic package. I am ditching it and have already ordered a new PP that goes with the 2 disk rally setup and will be ordering custom clutch discs from clutchnet like matt (y8s) did. I was quoted an estimated $45 for the job after describing what needed to be done over the phone. He said to him it just sounded like a custom resurface, which other than drilling/tapping it is. It might run a bit more because they would charge by the hour for the work but he said it would be 2 hrs max (so $90 max).

I will be dropping it off by monday along with my block/pistons.

too cool. any idea what the spring in the cover is? does it have a code on it?

I havent looked, do I have to take off those little nuts to find out?

no, and dont. that's a lot of spring pressure to release.

it should be on the fingers near where the release bearing rides. probably a 3 letter code. BUF, ORA, GRN, etc.

It is a grey spring.

so it's about 30% more pressure than mine. that's probably not too bad. probably hold 400 ft lbs with organic disks and the high ratio pp.

You just gotta gimmie those disk spec now so I can call clutchnet up :)

i my still have one
