Broken Flexplate - again?

how thick is the main plate? AFAIK its only a few mm thick not the same sort of thickness as the normal type flywheel.

And why the hell would you put a normal manual type flywheel on with something as heavy as a TC thats going to do a better job (assuming its all bolted up properly) of being a rotating mass than the flywheel itself?

surely not just to mount the reluctor ring on...

edit--------

BTW I consider a normal type Flywheel to be one of those big thick heavy buggers you bolt a clutch up to and wouldnt want to drop on your foot.

A starter plate is one thats only there to mount the ring gear to let the starter motor do its thing

A flex plate (in terms of engine-Transmission) is the plate the TC bolts up to be it a full diameter plate like the broken one in the top pic of rons post or a smaller hub drive as mentioned by rovercare (usually just a smaller diameter plate that only extends as far as the coupling bolts on the TC)

Many cars (auto's) have flywheels and flex plates

Surely you should know this Dave ;)

so far Ive never seen one that has a full thickness manual clutch type flywheel and a Flex plate..

Starter plates and flex plates yes but never a proper flywheel and a Flex plate and AFAIK theres 2 very good reasons for it

1. Mass, sure more weight helps keep the rotations smooth but it costs you in terms of acceleration. A TC weighs in at as much as some flywheels when its empty, add all the oil to it and thats more than enough weight to do the job putting a flywheel in as well, cmon thats just getting way out there (although if i had to put an auto behind a 3.9suzi that I knew was going to do lots of sub 1000RPM work ID consider this a + not a minus)

2. space flywheels arent skinney by taking the guts out of one and making it a flex plate or a starter plate you have more room for A, a bigger TC or b, you can shrink the gap between the donk adn the box by the same amount

and as a cherry on top to mount up the TC youd have to bore holes in or cast holes in the Flywheel which is more work to be done in terms of finish and balance.

Ive seen plant gear with the TC coupled to the flywheel directly tho...

The main plate is 3.25 mm and the thin one is 1.6mm - I just measured them with verniers.

Ok I just checked the LR parts catalogue. They call the the flywheel the "drive plate assembly" and the thin one the "drive plate - bare"

so we're having a difference of terminology here...

The main plate that is 3.25mm thick some of you calling the flywheel and Im calling it a starter plate and the manual is calling it the drive plate.

Same poo different shovels.

but we're all agreed that the shattered one in rons pic is the flex plate yeah... :angel:

Yea, I'm with you on this one, got called of to a job before hence the abrunt end to the post:angel:

I'd call the ring gear plate a flex plate, mainly out of visualization habit (tis what most flex plates look like, and the shattered one a drive plate, but either way is good enough I guess, a flywheel creates rotating mass and is generally a big thick bugger, neither of those here i'd call a flywheel;)

There is an inch wide boss between the 2 here, its basically what you'd machine up when making crazy conversion, but done from the factory by rover:)

Odd how they are shattering they, they are well spigoted:confused:

This is the previous flex plate (on right)
