    On my 2000 Jetta, I need to retard the timing a bit to bring into spec. Looks easy enough, but manual procedure indicates using the lock pin while tightening the three bolts on the sprocket. Don't think I saw any mention of that in the procedure here or in the nice video that idparts has on youtube. Is the idea that the torque (25Nm) is inconsequential to the timing belt system so it's not really necessary to counter hold? I have the pin so I'll probably follow the manual, just curious what more experienced folks think on this point.

    Tightening needs a counterhold. I would counterhold the sprocket, like counterholding the camshaft sprocket. The lock pin is second choice, because the torque goes also into the belt tension.
    Cheers

    Thanks. Sold my camshaft counter hold tool so have to see what else I can use. It's not a ton of torque so hopefully can fake it with something around the garage!
