TSB: Disintegrating Clutch Discs

[chazdawg35]

Got a TSB on a09060H

[Currently]

English please for the Hondese illiterate.

Yeah, please elaborate - is there a flaw in the clutch? What happened, what is being done, and is this something we all need to be concerned with?

[tsh]

This is old, not on the CRZ?

Technical Service Bulletin
And i think thats the Code or "Item" Number for it for lack of a better word?

Sorry about that, I got this off Mitchell on Demand from work. Applies to all manual transmission models,looking at a clutch housing that's filled with fibrous, fur like stuff? What you're seeing are bits and pieces of a disintegrated clutch disc, which can happen when shifting from a higher gear to a lower one while decelerating from higher speeds.

[chazdawg35]

Here's a typical scenario: getting off the freeway, you push in the clutch to coast to a stopat the bottom of the off ramp. Thinkingit's a goodidea, you drop into 1st gear so you're ready to take off when the light turns green. but you do it with the car still moving at a preaty good clip( faster than you should go in 1st gear). There is a bigbang or thunk and the next thing you know your calling a tow truck.

[chazdawg35]

What happened was as soon as 1st gear engaged, the wheels were driving the mainshaft, which oversped the clutch disc. With such a high mainshaft speed, the clutch disc material simply disintergratedfrom the extreme centrifugal force being generated, resulting in a bigbang and a big repair bill.

[tsh]

So this is nothing to do with the CRZ, so you might want to change the title of the thread and stop trying to scare people. Or are you admitting to having done this yourself?

It does look like a valid service bulletin (S2000, Civic, Accord and Fit.. couldn't find in listed for CR-Z, but it does state all Manual Transmissions)

But you almost have to be a freaking moron to have it happen.....

The TSB is merely explaining how this event occurs, I doubt very much this would be covered by warranty... as it requires massive stupidity on the part of the driver..
