Valve Guide for Kohler K241, K301, K321, and K341 Engines.

  • ID: 0.309"
  • OD: 0.625"
  • Length: 2.129"


  • Kohler: 235007-S



These guides will need to reamed to a final size of .3125" ID. You can do this with a 5/16" Chuecking Reamer Tool in a handheld power drill or with a handheld tap wrench chuck.

    Quality part.

    Old guide must be removed, new one pressed in and reamed with .325" chucking reamer. Complete instructions are available online from factory Kohler manual. Could pose problems if you don't have basic machining skills.

    Seem to be good quality but know they are undersized and reaming is mandatory
