Which flywheel do i have on my 4AGE?

[ballpencil]

Quick one:

A 4A-C clutch cover (or pressure plate) fits on my smallport 4A-GE flywheel, shown below.


Do i have the 200mm or 212mm flywheel?
It is of course an 8-bolt flywheel.

The reason i'm asking this is that i'm not sure if clutch covers are interchangeable between them.

try measuring the friction (shiny) surface of the flywheel.. it will be either 200 or 212mm

as for interchange. if all the holes line up, and there is no difference in (or no) step.. and the inner/outer diameter of the friction surface is the same.. why not?

JDM AE71 wagons had a 212mm clutch on the 4AC's, may explain it. You def have a 212mm flywheel, the 200mm ones don't come out as far as the ring gear like the 212mm ones, they're only as wide as the inner edge of the ring gear.

beerhead, it looks like he put his 4AC cover on there... not a stock fitment

[beerhead]

Hmm, could just be a funny angle photo and my beer googles Measure the clutch disc and you're laughing

Unlikely mine is a 212mm clutch 4AC as i'm from Indonesia and the 4AC was from a Daihatsu Charmant.
Correct me if i'm wrong. I read your post as stating that the ring gear outer diameter on 212mm is less than the 200mm. If that's the case, i'm afraid you're wrong. Both flywheels share the same ring gear outer diameter. This allows the starter motor to engage properly even if you swap the flywheels.

i would've done that had it wasn't too late. long unrelated story skipped, i end up not knowing which clutch i'm currently running INSIDE my T50 gearbox. so i can't measure the friction surface. i'm collecting turbo parts and better clutch set is on the shopping list. i don't want to buy the wrong set.

to add to the confusion, i previously bought an AE92 clutch set and the clutch cover didn't fit the studs on the flywheel. sooo.. assuming all AE92 have 212mm flywheel, i must be running a 200mm flywheel? can anyone confirm?

Hmm, could just be a funny angle photo and my beer googles Measure the clutch disc and you're laughing

as mentioned, this is impossible without unbolting the bellhousing and i'm planning to do that when i have the replacement clutch set to save labor.

anyone? sorry if any of my words didn't make any sense. i don't talk english primarily.

your english is fine

here says smallport is 212, and 4AC is 200mm...

is this you? oh it looks like your pictures
http://charmant4age.blogspot.com/200...omparison.html
here there is (your?) picture of 4AG smallport and 4AC flywheels.
both have a small step, so you could easily measure that.. if the engine and box were apart

were the studson the flywheel further out than the clutch cover? i mean, did the clutch cover seem too big or too small?

it is possible that the flywheel on your smallport was changed with a bigport flywheel, or other one...

do you have any photos of the flywheel before the clutch was put on? you might be able to measure the width of the friction area from the photo, rather than pull apart your car..
you just need to knwothe ring gear outside diameter...

[oldcorollas]

there are soem comparisons of 200 adn 212mm flywheel here

[oldcorollas]

i think what beerhead was saying, is that you can see more of the ring gear teeth on the 200mm than the 212mm, as in the last 2 photos.

but with your photo up the top, it is a bit hard to tell


is this the flywheel on your engine now? with the kind of gap between the ring gear and the front of the flywheel?

this 212mm flywheel (from Sam-Q again) looks like it has that same step

lol.. yeah that's my blog and YEAH THAT'S MY FLYWHEEL.

seeing the side-by-side comparison 200 vs 212mm, i'm also inclined to think my flywheel is 212mm.
here's the best pic of the flywheel i could find.


the first pic: seeing how the ring gears are not so exposed, it's quite similar to the 212mm on dreamsofdrifting.
the second pic: this is after dad helped me return the wrong clutch set and got the correct one. this one fits perfectly. the problem is dad didn't write down the part number (yeah he took the second pic, i was out of town).

here's the wrong set which was returned to the shop

there's a part number on the clutch disc: DT-124VA
a quick google gave me this link
the link stated that it's an 8-1/2 inch clutch disc. that's 212mm right? getting more confusing..

so why did the AE92 clutch set the seller gave me didn't fit? one possible explanation would be that he gave me the one for 4A-FE! we have both model here in Indonesia. but why did the 4A-C pressure plate fit?! it's definitely a 6-bolt 4A-C flywheel which should be 200mm! this could mean that pressure plates ARE interchangeble!

[ballpencil]

i'm confusing myself here.. let's list the facts

1. a 4A-C clutch cover fits on my 4A-GE flywheel --> if clutch covers are NOT interchangeable, then most probably mine is a 200mm flywheel except there's a freak chance that my 4A-C also has a 212mm flywheel

2. DT-124VA part number on the clutch disc states that it's 8-1/2 inch which is 212mm and the clutch cover for this disc didn't fit --> so mine is a 200mm?

3. the ring gear wasn't so exposed on my flywheel --> so mine is a 212mm? except IF there's a 200mm flywheel having exposed ring gear as it was the case on my 4A-C flywheel http://3.bp.blogspot.com/_lDE3zY3Oa4...h/DSC03711.JPG

one thing i CAN do is measure the friction surface on my 4A-C flywheel as it's just laying there on my frontyard after the conversion. but without knowing whether clutch covers are interchangeble, it's useless.

[oldcorollas]

do you have the part number of that clutch cover?

that picture of yours there looks like the bigger of the two.

can you measure the diameter of the ring gear teeth (of the 4AC flywheel.)? then i will try and measure the friction area from your photo

regarding friction plate and pressure plate, the 212mm friction plate may be able to fit inside a 200mm clutch cover...
or they put the wrong kit together?

it is also possible that a 200mm 4AC flywheel has the dowels further out than the 200mm 4AG...
do you have a spare 4AC pressure plate around, that you could measure the friction surface on?

ok, on your 4AC flywheel, measure the outer diameter of the ring gear, measure the friction surface diameter, and also measure the distance between the three dowels (in a triangle), and also clutch cover bolt holes (as a triangle, ie the ones next to the dowels)

[beerhead]

Had a mate pull apart a Jap delievered AE71 panel van. They have reduction starters and a 212mm flywheel from factory So it is possible that the 4AC's in your part of the world ran the bigger flywheels. If the clutch fits now bolt it back together and drop a skid

[knightrous]

Sure the AE92 clutch you bought wasn't for a 4AGZE which has a 220mm (or is it 225mm?).
Would explain why it wouldn't fit.

[Shifty]

it's been said before

just measure it

no confusion

i'm confusing myself here..
