Illustration 1.
Illustration 2.Two-Jaw Pullers Available
These two-jaw pullers complement existing three-jaw pullers 1U6400, 1U6405, 1U6410 and 1U6415. Many of the piece parts are common between the two sets. The two-jaw pullers can be used in applications where lack of clearance prevents the use of three-jaw pullers.
Illustration 3. Typical application of one of the new pullers.The unique feature of these pullers is the positive retention of the puller jaws. The jaws are clamped to positively hold the puller in place. See illustration 3. Turning the T-handle moves the puller cage against the jaws and secures them to the part being pulled.
Illustration 3 shows the puller being used to remove steering ball studs from off-highway steering links. For example, 4C3085 can be used to remove 776/777 truck steering ball studs. The 4C3088 and 4C3091 Pullers are used to remove king bolts from 768/769, 772/773 and 776/777 truck rear axle housing at the pivot connection with the truck chassis.
The pullers provide positive methods of securing components being pulled. The pullers are simpler to apply and more economical compared to hydraulic pullers of equivalent capacity. These new pullers should relieve some of the hydraulic cylinder requirements resulting in a reduction of service labor time.
