6.5 in Heavy Duty Bench Vise with Anvil and Swivel Base

A transmission bench is only as good as what holds the part still. This vise has a 6.5 in jaw width, a 6 in maximum opening and a 3.8 in throat depth, which is what you need to get a valve body, an extension housing, a governor cover or a servo bore up off the bench and square to you instead of pinched at the very edge of the jaws. Clamping force is rated at 9,900 lbs and the body is cast from 60,000 PSI ductile iron, so it takes hammer work on the anvil without cracking the way gray cast iron vises do.

It ships with two sets of jaws. The replaceable flat jaws handle general bench work, the slot jaws grip round stock, and there are built-in pipe jaws underneath sized for 1/2 in through 3-1/2 in pipe, which covers cooler line, dipstick tube and shift shaft work. The 210 degree swivel base locks with two lockdowns, so you can spin a case half toward the light, lock it, and it stays where you put it while you drift a bushing or press a seal.

Practical notes before you bolt it down: the anvil pad measures 3.1 x 2.9 in, the vise weighs about 40 lbs, and overall footprint is 14.6 x 8.1 x 8.6 in. Mount it to a bench top that is at least 1-1/2 in thick or a steel frame, and put a washer under each nut. Use soft jaw covers on aluminum valve bodies and pump halves; serrated steel jaws will mark a machined face. Keep the screw and slide greased and back the jaws off when the vise is idle so the slide does not sit loaded.
