    I’m at the point of needing the cam follower gaskets. Order a kit or order exactly what I need? Here’s some pics of the dial indicators, for each follower. 787C5EE7-4944-4A4B-9F5E-C0F61083BC68.jpeg AFCBE6F4-5A1A-4C63-91A2-4B687979DF70.jpeg 31471019-8A0D-47BB-BAEA-FC340F32D536.jpeg First pic is the rear, then middle and front.

    Call ATL Diesel. They are in the cam business. Surely they can set you up with gaskets.

    Do you know what the thickness of each of those is? How close can what you got or kit get me to where I need be, on each follower? Is, “crush” considered?
     
    OLDSKOOLERnWV Thanks this.

    Not sure what the setting is that you are looking for, but if memory serves me, it’s like .007 of gasket makes .002 change on your injector timing reading….

    What timing spec are you trying to get to? The measurement is taken at .203 before tdc.

    When you set the gasket and follower in place, install at least 3 bolts in the follower and tighten them up, don’t have to be torqued, just tight. 1 bolt in the front at top, 1 in center at bottom, 1 in rear at top. Or you can put all 6 in. Just make sure the bolts are snugged up tight.

    Hang the gaskets on the dowels in the block to hold them in place, don’t use any silicone to hold them while making adjustments finding the desired thickness…
