    1. Why King Subaru XP flange bearings do not have locating lugs?<\/h3>

      In order to prevent a oil leak path, therefore lowering oil pressure, \u00a0the lug has been removed from the King thrust bearings for the Subaru EJ, FA\/FB engines. Symmetrical thrust bearings do not need a locating lug for exact placement because the flanges do this automatically.<\/p>\n<\/div><\/div><\/li>

    2. What is the difference between pMax Black\u2122 vs. pMaxKote\u2122?<\/h3>

      pMaxBlack<\/u>\u2122<\/u> <\/strong>is a surface hardened \u00a0lead tin copper overlay that is electroplated onto a copper alloy substrate making up the third layer of a King XP bearing. \u00a0pMaxBlack also has additional \u00a0copper content, when compared to regular tri-metal\u00a0 bearing overlays, \u00a0increasing \u00a0the fatigue strength to handle loads up to 10,200 psi.<\/p>\n

      pMaxKote<\/u>\u2122<\/u> <\/u><\/strong>is a factory applied nano composite polymer coating formulated especially for pMaxBlack overlays. pMaxKote provides excellent wear and cavitation resistance while protecting bearing surfaces during periods of oil starvation and minimum oil film thickness.\u00a0 pMaxKote is applied with no added wall thickness therefore not altering oil clearances.<\/p>\n

    3. How King’s pMAX Black material can affect the journal surface?<\/h3>

      There is absolutely no effect or damage causes by Pmax Black to the journal surface.
      \nPmax black bearings differ from the competitive bearings due to a special surface treatment of the overlay. The treatment produces a strong ultrathin (nano-scale) skin which inhibits formation of fatigue cracks. Therefore load capacity of Pmax black bearings is at least 17% greater than that in the competitive racing car bearings. Hardness of Pmax black overlay is also higher than that of the competitive overlays (by 24%).
      \nThe value of hardness 18 HV in comparison to 11-14HV of competitors is still low enough to provide excellent<\/strong> anti-friction properties of the bearings (embedability, conformability and compatibility). For example hardness of aluminum alloy in bi-metal bearings is about 40HV.
      \nThe extremely low (nano scale) thickness of the hardened surface layer of Pmax black bearings guarantees that the journal surface can not be damaged (scratched) during metal-to-metal contact. If direct friction occurs the surface shield wears off from the overlay surface producing no scratches on the steel surface.
      \nThe effect of direct friction between tri-metal bearings (surface hardened and non-treated) and steel journals has been tested in King Test Rigs. The results proved total indifference<\/strong> in regards of the journal surface damage between the treated (Pmax black) and non-treated bearings.<\/p>\n<\/div><\/div><\/li>

    4. How much clearance should my bearings have?<\/h3>

      In order for bearings to maintain a stable oil film, which is vital to their life, there must be a perfect match with clearance size, oil viscosity, engine operating \u00a0temp, crank surface finish and geometrical alignments. General rule of thumb for determining oil clearance is .001 of clearance for every inch of shaft dia. Ex .001 x 2.00 shaft dia. \u00a0= .002 oil clearance.\u00a0 For clearances smaller and larger than the rule of thumb ,refer to the factors listed below:<\/p>\n
