Subject:	Minutes of T-12 Teleconference of Nov. 17, 2004
Attendance - Riccardo Conti, Jim Moritz, Bob Campbell, Andy Broff, Ron Buck, John Haegelin, Greg Shank, Ken Goshorn, Jim Matasic, Jeff Clark, Scott Richards, Pat Fetterman

Membership - no changes.

Minutes - minutes of 11/8 TelCon were approved.

Test Procedure and Data Dictionary Update (J.Clark) - Jeff will send out an updated procedure when new pictures are available. Andy Broff of SwRI volunteered to provide the pictures (Thanks, Andy!). We will review remaining procedural items in Paulsboro. The data dictionary and report packet will be available for beta testing in the next few weeks.

Hardware Update 

The test parts list (R.Buck and K.Goshorn) has been completed and distributed. 

The T-12 cylinder rebuild kit is now Mack P/N 57GC3137. Six of these are needed for an engine rebuild. TEI will include six rebuild kits, main (thrust washers included) and rod bearings (enough for a complete engine build) in the T-12 kit. 

Modine Cooler (R.Buck and K.Goshorn) - labs are having difficulty obtaining these and this now appears to be causing delay at the labs.

Intake manifold - labs still need the stainless manifold, TEI is working on obtaining these.

Ring Wear Measurement Sub-Group Update (K.Goshorn) - Volumetric mass loss measurements are considered proprietary by the ring manufacturer. They have offered gages to make measurements for to allow for face and side wear to be broken out separately. It was suggested that the ring manufacturer study the wear from the matrix data using their measurement technology. Mack will investigate if the supplier is willing to do this.

EGR Coolers Cleaning Procedure - SwRI is still investigating this. Following this update, a conversation concerning the possibility of condensation and intake manifold temperature took place. Mack indicated that at this point, they do not want to change operating conditions.

Dyed Fuel - Mack is on record as saying that they have no problem using dyed fuel for the T-12 This will be a more complicated issue for the existing tests and the Mack SP will need to address the T-8, T-10, and T-11.

Next Meeting: 11/22-23 in Paulsboro-NJ
