« on: April 06, 2008, 07:02:21 PM »
    1.    choices... cast/forged ??? forged is best.


    2.    "crank inspection";...    check rod/main for size.


    3.    check  snout for wear/ balancer bolt threads/ crank main thrust for wear.


    4.    "performance crank grind" ... should include the following.
           
            clean/inspect/mag./check rod throw width/checkmain width/  straighten / cut centers,
            grind rods/mains,polish and chamfer, / radius fillet areas.  hold tolerances at  +/- .0001/10.
                   

    5.     check and adjust rod throw / detail crank, deburr and prep. for assy.


    6.     blueprint / balance all components / final inspection by assembler.



                these are basics only people.... for those of you that want to ad to this , feel free :)
               
    7.     stay away from your $ 30.00 crank grind  ,  welds,,, etc... you get what you pay for
            and this is by no means an area to fool around ::)


    8.     many operations  to numerous to mention are available , such as :

            cross drilling / strenthening / cold casing / offset grinding / knife edging ,
           
            1/4 key  crank,    and much more.

                      this is just "BASIC  STUFF".


                          hope this helps you ...... next time     "CYLINDER HEAD WORK"!
