    SBC & BBC Valve Lash Adjustment Procedure

    Did You ever wonder where that 3/4 to 1 full turn of the rocker arms nut would put the piston in the hydraulic lifter to.
    Meaning: Ideally, the piston inside of the hydraulic lifter should be close to 1/2 way between the top and the bottom of its travel, if the lifter would be void of any oil.
    This guy here says that 1/4 to 1/2 of a turn on the nut, with hydraulic lifters, should get the adjustment so the piston would be about 1/2 way down. :SHRUGS: :confused:
    It appears that this website has been relatively inactive for quite sometime so, if You like the article, my suggestion would be to print it out so that You have it for future references.

    A new member pmed me earlier ask how to remove the sleeve in front of the drive gear. He seen this thread on a search.
    So in pm i added to it today..how to remove the sleeve ,and drive gear from the shaft....this is electronic speedo..to cable driven.
    Hello and welcome... apachomatic to the forum. Sleeve is easily worked off the Output Shaft by hand.., Rock it back & Fourth till it comes off. Replace the O-ring while it's out.
    [​IMG] If it is stuck a little.. the sleeve try opening up a pair of channel lock pliers or a big adjustable wrench .. and place it over the sleeve,.. than bang on the tool with a hammer and see if that gets it off.



    Here is a video from youtube how to replace the drive gear on the shaft.


    I will move it to General forum sticky.

    Good info.
    I've fixed machinery shafts that looked worse than that damaged output shaft. It's not a job for the impatient. You'll be cussing Bubba out the whole time.
    Carefully cut the high points down with with Flat Mill and then Flat Fine files and then use diamond files and stones to get it as close as possible to the original diameter.
    If you have a seal running on part or all of the damaged surface you can use a Speedi-Sleeve to cover the low spots after you get the lifted metal cut down.

    There's at least one outfit that makes dual mode gear and VSS tail housings for the TH700R4/4L60.

    Anyone have the 4L60 (not E) manuals? I started digging into an AT rebuild project that is long past due. Thanks for any help.

    The 1990 & 1991 GM Unit Repair Manuals have a section on the 4L60. Look in my signature.
