2 SERVICE INFORMATION Nr. 27_06 Type: all Version: all Date: Mailing list of SSO: all Assembly: Page 1 of 1 Mailing list of OEM: all Mailing list customer: all Changes in the ZF List of Lubricants TE-ML 02 In January 2007, the new ZF List of Lubricants for Commercial Vehicles, TE-ML 02, will be published. Once again, we would like to draw your attention to the following, specific changes in the List of Lubricants: Eliminated from the lubricant category 02L -> the oil grade: CASTROL SYNTRANS This oil no longer corresponds to the requirements established in the List of Lubricants, TE-ML 02, and consequently, it may no longer be used for repairs or oil changes within the context of standard maintenance/servicing works. Newly added to the lubricant category 02L -> the oil grade: FUCHS TITAN CYTRAC MAN SYNTH 75W-80 This oil fully corresponds to the requirements established for the lubricant category 02L. Note: The previously used CASTROL SYNTRANS oil grade from the lubricant category 02L must not be mixed up with the CASTROL SYNTRANS MAX 75W-80 oil grade of the lubricant category 02E. Recommendation: After transmission repairs, we always recommend to only use oil grades from the class 02E. Thus, it can be ensured that the running in behavior is effected under the same conditions for those spare parts newly installed during repair jobs as for the standard volume production transmissions. Validity: This Service Information is valid as of January 01, 2007 for an unlimited period. Author: W. Ammann, LKS-T dept. i.a. Ammann Reviewed: i.v. Stauber Viewed by: i.v.
