    Hey Guys
    How do you tighten the Harmonic Balancer to get it to 184 Lbs. of Torque? I used the technique of using a long arm ratchet against frame and turning over engine to loosen it.
    Thanks

    Is your truck a manual or Auto.
    If it’s a manual, put it in 4th/5th gear and crank it down.

    If it’s an Auto, you need to make a tool.
    Or buy one. The pulley has some threaded holes I believe?
    It at least I believe there are holes in it?

    Gotcha, makes total sense, with all the dirt on the balancer I didn't even see the holes until now. Just chased the threads now. Will need to finish cleaning it up.

    there is typically a special tool used to counterhold the pulley while torquing the crank bolt
    which can be a one time use stretch bolt with a final degree turn

    I’m trying to replace my harmonic balancer. I received a new one from Dayco and there are two grooves, one in red arrow and one in blue arrow that confusing me. My thought was that all I needed to do was just lineup that red groove with the crankshaft and I’m good to go, but when I checked the metal rod that was sticking out from the engine crankshaft, nothing was protruding to match that red groove for a lineup. So how do I install this? And what is the blue arrow for? (2007 Tacoma V6)

    should be a key way on the crankshaft. I believe the blue is once rotated to align with a spot on the block it’s at TDC

    I have the tools I need, I just need to help to install it.


    Do you have instructions on it?

    What specifically do you need help with?

    Slide the pulley onto crankshaft as far as it can go. Install the pulley holder and tighten the crankshaft bolt to the specified torque. Remove the tool, you are done.

    Assuming you have the correct pulley, you just need to install it, there is nothing to do with timing.

    red is a key hole
    blue is a timing mark

    installation is reverse of removal

    you don't line it up anywhere unless you are trying to replace the timing chain or camshaft/gears

    So I guess, just slide in the crankshaft pulley, put in the bolt, and tighten it up then torque it.

    I wouldn’t use the bolt to pull it in, that’s a good way to stretch the threads

    The pulley is not pressed on. The pulley should just slide onto the crankshaft. The bolt holds it down.
