BOTTOM VISE JAW REPLACEMENT
FIGURE 3
Remove the top vise jaws. The bottom vise jaws are secured by two #10-32 x ½” long socket head cap
screws. Use a 5/32” Allen hex wrench to remove the screws. If you have difficulty accesing the bottom
screw you may remove the top plate. See figure 4 below.

To remove the top plate you must first remove the key clamping knob assembly with the 3 piece radial
thrust bearing and the knurled knob. Use a 7/64” Allen hex wrench to remove 4 #6-32 x ½” long socket
head cap screws.
Remove bottom vise jaw from 1” diameter plunger. Wipe plunger and carriage surfaces clean with a lint-
free rag or paper towel. Bolt a new bottom vise jaw onto the plunger; loosely do not tighten the two screws
at this time. Use Sta-Lube Super White Multi-Purpose Grease (available in Auto Parts Stores). This is a
Lithium grease, Grade 2, 350° F min., and water resistant lubricant.
Coat all steel sliding surfaces (back side of bottom vise jaw and plunger and all aluminum mating surfaces
on the carriage). Also apply this grease to the 3/8” threaded hole in the plunger.
Gently slide the assembly into the carriage from the top. Snug up the two screws securing the bottom vise
jaw and check that the assembly slides up and down in the carriage- do not tighten the two screws at this
time.
