Abstract: A first kit includes a manually operable hydraulic pump, a hose and a fitting for transferring the pressure in the pump to the hose. A second tool kit for bearings of relatively small size includes a fitting for coupling to the hose in the first kit and a C-shaped clamp having a pair of legs movable toward each other in accordance with increases in pump pressure. A third kit includes a receiver die and a driver die movable with the clamp legs to remove a bearing from a housing, an anvil die and a driver die for installing a bearing in a housing and a die set for swaging a prepared lip in a bearing race into a prepared chamfer in a housing. A fourth tool kit for bearings of relatively large size includes a fitting for coupling to the hose in the first kit and an in-line press having a pair of legs movable toward each other in accordance with increases in pump pressure.

Abstract: A control valve for controlling the flow of fluid to and from a single-acting cylinder and having a metered flow-controlling valve section and a rotatable valve member movable to four different positions to provide four different operations of the single-acting cylinder, namely: rapid advance, slow metered advance, hold and return.

Abstract: An adjustable work support for relatively light loading having an extendable plunger locked in position by a fluid-operated piston which acts on a disc positioned between the rod of the piston and the plunger and which is urged to a position to take up clearance to avoid shift of the disc and resulting inadvertent retraction movement of the plunger. A sealed cavity with a flexible bladder communicates with a piston chamber housing the piston and a closed end of the bore mounting the plunger whereby flow of fluid to the sealed cavity avoids any ram effect on the plunger when the piston is operated to lock the plunger in position.
