Subject:	Minutes of the Mack T-11 Task Force Teleconference of  March 3, 2003.
Here are the unapproved minutes of the Mack T-11 Task Force Teleconference of  March 3, 2003.
The meeting began approximately 2:05 pm Eastern time.

Participants: 
Jeff Clark, Steve Kennedy, Jim Matasic, Scott Richards, Jim Moritz, Tom Franklin, Joe Franklin, John Haegelin, Charlie Passut, Bob Campbell, Steve Gearhart, Ron Buck, Pat Fetterman, Mike Minotti, Andy Ritchie, Wim van Dam, Greg Shank, Ken Goshorn, Mark Cooper.

Action Items:
1. Task Force Members are to consider the MRV temperature issue and be prepared to discuss at the next meeting.
2. Labs are to configure oil pans as agreed upon.
3. Jim Moritz will distribute an oil pan sight glass design.
4. Test labs are to take upcoming reference test eot samples from both the oil gallery pressure tap and the auxiliary oil sump.
5. Ken Goshorn will distribute details on sampling oil from the oil gallery pressure tap at the oil filter head.
6. Labs are to provied TEI with how many engine blocks they believe they'll need in the next five years. This information should also include the number of blocks currently on hand and the number of test hours on each block.

MRV Temperature:
Test procedure does not specify the MRV temperature. The task force will need to decide if -20 degrees should be used or if the vis grade should determine temperature. Steve Kennedy requested that members consider the issue and be prepared to discuss this at the next meeting.

Oil Sump Configuration:
After a review of the possible configurations, the following was decided:
The auxiliary oil sump suction is to be located at 6.0" from the top of the pan rail surface to the bottom of the inside of the fitting on the exhaust side of the engine(Goshorn, Moritz, 10-0-0).
The oil sump t/c is to be located 5" from the front and 7" from the top of the oil pan on the exhaust side of the engine (Campbell, Richards, 10-0-0).
A sight glass will be used to aid in knowing oil level should the auxiliary oil sump go dry. A sight glass design will be circulated by Jim Moritz.
If the auxiliary oil sump goes dry, samples are to be taken from the oil filter head, at the oil gallery pressure tap. For the first round of reference runs, labs are to take EOT samples at both the auxiliary system and the oil filter head (Richards, Minotti, 10-0-0). Ken Goshorn to provide details of the sample tap.
If the auxiliary oil sump goes dry, the auxiliary pumps are to be shut off.

Other Business:
ExxonMobil has completed a "T-10.5" on oil 820-2, it finished at 7.27% soot and the 204 hour viscosity was 21.64 cSt, preliminary 252 hour vis was 27.8 cSt.

After some discussion, it was re-iterated that all future tests are to be run with the stainless steel intake manifold.

SwRI has 132 hours on a test, PerkinElmer will be starting a test this week, Ethyl will start a test in about a week, ExxonMobil potentially within 10 days, and Lubrizol within 2 to 3 weeks.

TEI has located and purchased a supply of the "old style" engine blocks. Labs are to provide TEI with an idea of how many blocks they think they may need in the next five years. This input should also include the number of blocks currently held and the number of hours on each block.

The meeting concluded at 3:15 pm Eastern time.

Next Meeting:
Tentatively Scheduled for
April 22, 2003
8am to 1 pm at SwRI
Note: the afternoon or following day will be reserved for O&H group lab visits
