Description
49 Spline Transfer Case Pump with MA Pump Plate | 2001-2007 — 25905
Do I need the 49-spline or 38-spline pump? It depends on your transfer case's mainshaft spline count. HD cases can have either one, so count the splines before ordering. For 38-spline cases, see our 38 Spline Pump with MA Pump Plate .
How do I know if my pump needs replacing? Check the pump during any rebuild. If the metal is discolored from heat, or if there are scrapes or gouges deep enough to catch a fingernail, replace the pump rather than reuse it.
