Slide cross shaft shear bolts are 1/4"-20 1.5" long Grade 8 bolts.
Worth having a few on hand in case it happens. Fairly easy fix. Have to open up the belly near the ends where the rack gears are. The cross shaft is connected at each end on inside of rack at each end of slide. If the bolt is gone thats the one. Can watch when slide is tried, you will see it slip. The symptoms are the same no matter which end is sheared, so its a crap shoot which end to check first. Make sure slide is perfectly in sync before replacing bolt.
There is no doubt what is wrong when they go. The end with the ram moves and the other one doesn't.
I have changed 2 on one slide and 1 on the other. Never at a good time either.
