The tests of gear tooth failure and for predicting allowable surface durability of gears lubricated with grease material were conducted. Grease made from the penetration of NLGI NO. 0 contained non-lead EP additive and lithium soap thickner. The gears used for the tests were spur gears with 2.5 module, 31 and 35 teeth, and addendum modification factor X_1/X_2=0 2/-0.18. The value of the tooth load was changed from P_n=101.0 to 557.0 kN/m and the value of the pitch line velocity was also changed from V=1.59 to 6.19 m/s. The following test results were obtained : (1) the scoring type of failure mainly occured, and at higher load conditions, spalling was also observed. (2) allowable tooth load Pn could be predicted from the specific wear of tooth surfaces.
