Alot of it comes down to the material being used for the gears, the heat treatment, and the post-grinding work.  The other variable is the gear oil; I typically don't use anything as thin as 75w90 unless the car is below 400-500HP; 330-370kW.  I would rather use a 75W140 gear oil with higher power levels, as well as higher transmission temperatures.  

What was the bearing preloads measured on the shafts at assembly, and what are they at now?

The gear tooth profile design will also cause wear patterns like that, with tip loading, galling, pitting, and surface deformation, but again, you need both gears ground after heat treatment to make sure they are meshing properly.

The results shown in the photos are disappointing as it further appears that a PPG gearset is pretty much the only option for this platform anymore for high quality gears that are profiled properly, heat treated properly, and finish-ground properly.

Tim..will be in touch.

Mini bloke...not sure about alternator I do know its amperage is lower than Evo...PS pump..no

No problem dude, just send me an email directly, or a PM here (I will log in more often to watch for anything).  My email is [email protected] or facebook me.

Thanks!

Well, I would have paid that easily for a good condition 5th gearset with hub/slider assembly.

Otherwise, I'll take the 5th gearset and 5/R hub and slider assembly.  What specific model transmission is it??  W5M33-2-xxxx, what are the last 4 digits on the trans bellhousing ID?

Shoot me a PM or email to [email protected]
