Subject:	T-12 Minutes of 10/1/04
These are the unapproved minutes of the T-12 conference call of October 1, 2004.

Attendance - Jim Matasic, Bob Campbell, Riccardo Conti, Ron Buck, Jeff Clark, Jim Gutzwiller, Jim Moritz, Scott Richards, Andy Broff, Greg Shank, Pat Fetterman

Membership - no changes to membership were announced.

Minutes - minutes of the 9/23/04 teleconference were approved.

Hardware Update (R. Buck)
Engine Blocks - Ron has not been able to locate the old style block. The new style block (5551M) has been superceded by the  5553M. There are 22 ('53M) blocks available at about $4500 each. It is uncertain if these are currently in production. Ken Goshorn is investigating the differences between the '51 and the '53. It was approved that labs that want to start on the new style block can, provided that it does not cause a delay in testing and development. Any currently running tests or development may continue on the old style block, however, by the start of the PC-10 matrix all tests will need to be run on the new style block.

Oil Pumps - The old style oil pump (465BM) shows 14 available, a total of  26 when including TEI stock. There are no new gears (9 tooth gear) available for the old style oil pumps. Ron will verify that the 14 pumps are new and not re-manufactured. Concerns were expressed over whether this inventory would be sufficient to last the life of test without having to change to the new style oil pump. This will likely be discussed again when more information is available. In the meantime, we will be staying with the old style oil pump.

Modine Coolers - Ron found a distributor that will sell individually at $7800 each. There may be a discount for ordering a lot of 10. Ken Goshorn is working through Mack Service to see if he can get a better deal.

Bearings - the tin flash conrod and main bearings (production) will be used for the test. 

Dyed Test Fuel - Greg commented that Mack does not have experience with dyed test fuel and they cannot forsee what, if any, impact it may have. For the time being, we will stay with un-dyed fuel and try to work this issue off-line with the other test areas. It was also confirmed that the T-12 will run on PC-10 fuel (ULSD). 

Ring Wear Measurement Sub-Group Update - Ken has started the process on this by contacting the ring supplier. The group will wait for further information.

Next Teleconference Call/Meeting - Unless new information drives the need for a call sooner, the next call will be Friday, Oct. 8, at 9:30 am Eastern. A face to face will need to be held as soon as  the San Antonio labs are ready for a group visit.
