What's so strange is I've never seen a PPG helical synchro set break which is supposed to be the weakest one.
Sorry to hear. |

question now is....are they replacing the gear for no charge?? I can only imagine they will, but it's never really come up before since this is the first documented break.
Keep us up to date. |

By the looks of the break it doesn't appear to be a material issue(tooth next to it with a impact mark held up ok) but a metal fatigue issue. There is no slow crack development, indicated by growth rings(like on a tree). It only has the looks of a sudden break(sandblasted or sandcast look). Meaning it was just pushed up to its working load limit and then sheared off. Not that surprising with that number of strip runs on it. Some info on metal fatigue from wiki, enough for you to get the idea.

Its definitely not the first break, helical and straight cut are damn near the same strength as told to me by Andrewtech.

No, there have been a few failures, but none yet due to power. It's always been install and there were some other warranty issues.

This is what makes it so difficult to buy these things. They are already expensive as it is, and yet they are the only ones that seem to know how to install them properly. Might as well put the installation of these things into the price tag and call it 6000 instead of 5000 for them.

meh.... nothing is unbreakable... Perhaps there is something about the conditions under which the gears were used that caused their demise... for example, was driveline slack taken up on the dragstrip before the launch?

Yeah I would have had Andrewtech install the gearset myself. It is your choice. BUT, look at that carnage..er..more like a paper cut. That gear busted ONE tooth off.

I want to know what the resolution to this problem will be. Any word from PPG on these gearsets? Any word from AndreTech? Has this happened ever before? History on this gearset - where it came from (vendor), who installed it, was it new, ect. Hook us up with all background info.

Didn't you have an APS gearset and break the main shaft also?
As others have asked, who installed the gears? If not Andrewtech...I've heard so many other horror stories about "my local transmission guy" installing new gears and messing stuff up. |
