An apparatus for providing a load on a bearing mounted to a shaft which includes an attaching member releasably connectable to a shaft and a press mechanism coupled to the attaching member. The press mechanism is configured to provide a compressive load to the bearing. The press mechanism includes a wrench engageable with the lock nut on the shaft and the wrench is configured to engage and rotate the nut when the attaching member connects to the shaft. The wrench is moveable axially relative to an axial dimension of the press mechanism between a proximal non-engaged position and a distal engaged position such that the wrench engages the nut in the distal engaged position and the wrench avoids engaging the nut in a proximal non-engaged position. An aligning ring may be located around the attaching member and may be configured to engage a shaft slot.

A method of adjusting preload on a bearing assembly of a wheel mounted on an axle or spindle with a lock nut includes mounting a preload adjustment tool onto a threaded axle or spindle. The load on the bearing assembly is increased using the tool. The wheel on the axle or spindle is rotated to set the bearing assembly. The load on the bearing assembly is decreased to a desired maximum preload on the bearing. After decreasing the load on the bearing assembly to a desired maximum preload, the lock nut is tightened by hand until the lock nut cannot be further tightened. The lock nut is loosened by rotating the lock nut to a preferred location where a guide mark on the tool aligns with one mark on the lock nut located closest to the guide mark wherein a resultant preload on the bearing assembly is within a preset range from the desired maximum preload.

An apparatus for providing a load on a bearing mounted to a shaft which includes an attaching member releasably connectable to a shaft and a press mechanism coupled to the attaching member. The press mechanism is configured to provide a compressive load to the bearing. An aligning ring has an aligning projection configured to engage a shaft slot of the shaft to align the press mechanism relative to the shaft when the attaching member connects to the shaft. The projection extends radially inwardly from a circumferential portion of the aligning ring. The aligning ring extends circumferentially around the attaching member and is rotatable relative to the attaching member. The aligning ring includes a plurality of ring indicating markings to allow an alignment of a ring indicating marking of the plurality of ring indicating markings with a lock nut connected to the shaft.

A system for use in providing a load on a bearing mounted to a shaft includes a preload apparatus having a first extension and a second extension engageable with an inner race of the bearing and configured to provide a compressive load to the bearing. The first extension has a first projection and the second extension has a second projection. A stop ring is configured to limit a radially inward movement of the first extension and the second extension toward each other to position the first projection and the second projection relative to the bearing.

Embodiments of the application can provide methods and systems for the adjustment of gate valve boxes using custom fit gate valve box adjusters and the like. A gate valve box adjuster may include an alignment portion, an engagement key, a base plate, angle plates, and perhaps even an extension bar which may be attached to a motor and equipment.

A power tong assembly includes a power tong and a speed limiting system operably coupled to the power tong. The power tong is configured to grip and rotate a tubular segment in a first direction to make-up a threaded connection with the tubular segment and in a second direction to break-out the threaded connection with the tubular segment. The speed limiting system is configured to selectively allow the power tong to rotate the tubular segment in one of the first direction and the second direction at a maximum speed while limiting the power tong to rotate the tubular segment in the other of the first direction and the second direction below the maximum speed.

The present invention is a novel backflow meter Seatdriver apparatus which is much like a screwdriver. Its novel direct connection of the Seat Head slot, Driver Shaft and the Driver Handle work together creating one apparatus known as the Seatdriver allowing for easy installation and removal of backflow valve seats. This apparatus functions as a two in one device providing a check valve seat connector on one end and a relief valve seat connector on the other end. The Seatdriver channels on the handle matches the seat part profile which reduces the Camming Out effect which in turn increases the hand torque force, increases thread alignments, and holds the valve part in place during the replacement.
