    Primary sheave and secondary?

    Removing my primary sheave this week. What size bolt is required for spreading the secondary to remove the belt? Also its a 27mm socket or can you use a 1 1/16" socket for removing the primary nut. Thanks

    I don’t know about X2 and X4 but on Gen 1 you can use one of the bolts that hold the bearing support cage on to spread the secondary. I assume it’s the same way on yours. Metric sockets are best.

    Yeah never thought about the cage bolts being the right size. I have the 27mm socket as well. Looks like I'm good to go. Thanks.

    If the socket fits tight it doesn't really matter if it's metric or SAE. (13mm fits 1/2" perfect)
    If it's a sloppy fit as long as your using a 6 point socket it work in a pinch.

    I'm not sure about the X2/4 but all the ultramatics I've worked on in the past had 2 of the bolts that hold the belt cover on that were longer than the rest(1/2 to 3/4" IIRC). These 2 are for spreading the secondary

    Yeah a 1 1/6" would have worked fine and it was a 12 point. However I found I had a 27mm.

    If I'm not mistaken I used bolts from the belt/clutch housing cover when I did my weights.

    DeWalt worked great for removing the primary nut and torquing it back down. It has 3 torque settings.
