Abstract: Systems and methods are provided for efficiently maintaining a transaction sequence witness service to ensure that requests to read data provide consistent results across all storage nodes in a distributed system. When a storage node receives a request for a data object, the node may obtain—from transaction sequence witness service—the latest sequence number associated with the object. If the sequence number indicates the object has been modified in the period of time since the currently stored version was stored, the node can obtain the current version from persistent storage.

Abstract: A fleet node management system may include a metadata store, a plurality of fleet nodes, and one or more metadata mutation devices. The metadata store may be configured to store dynamic metadata. The plurality of fleet nodes may be configured to determine, based on a gossip protocol, whether to continue performance of a function that uses a local version of the metadata. The one or more metadata mutation devices may be configured to determine, based on a global state of the fleet nodes, whether to modify the dynamic metadata for the fleet nodes.

Abstract: A valve lash adjustment system for setting a valve to a rocker arm clearance for a valve train associated with a particular combustion cylinder for an engine is disclosed. The valve lash adjustment system includes a frame assembly including an engine head attachment portion and an instrument attachment portion. The engine head attachment portion of the valve lash adjustment system is removably attachable to the engine and the instrument attachment portion is selectively positionable relative to the engine head attachment portion. The valve lash adjustment system also includes an instrument assembly including at least one position sensor and at least one display unit. The valve lash adjustment system further includes a gap setting gauge assembly having a clip member.

Abstract: A strainer removal tool for the removal of a strainer is provided. The strainer removal tool includes a first member with a first handle portion and a first jaw portion. The strainer removal tool further includes a second member with a second handle portion and a second jaw portion. The first jaw portion and the second jaw portion include tip portions with a tooth portion, a recessed portion, and a clamp profile. The tooth portion is positioned radially inward to engage the locking tab of the strainer. The recessed portion of the tip portion includes a cut-out portion to receive the perimeter portion of the locking tab of the strainer. The clamp profile has a radial portion, which overlays the perimeter portion of the locking tab. The first member is pivotably attached to the second member between the handle portions and the jaw portions.

Abstract: A timing pin module for an engine is disclosed herein. The timing pin module includes a mount end, an engagement end, an adapter, a pin, and a resilient member. The adapter, with a through hole is disposed on the mount end and is mountable to the housing cover. The pin has a longitudinal axis, a first end disposed on the engagement end, and a second end disposed on the mount end. The pin is slideably disposed in the through hole of the adapter and moves between an extended position and a retracted position. The resilient member has a first end engaged with the pin and a second end engaged with the adapter. Further, the first end of the pin engageably retains the flywheel in the top dead center position while extended, and makes sliding contact with a portion of the flywheel that is in the retracted position.

Abstract: The disclosure describes a lifting system for use with a hoist, comprising of at least one structural frame rail, attached to middle portions of cross members on the opposite ends of the frame rail, such that the two cross members are co-planar. Each end of the cross member is attached to an attachment assembly. The attachment assembly comprises of an extension link and a detachable pin member assembly. On end of extension link is attached to the cross member and the other end is provisioned to receive the pin member assembly. A lifting lug assembly is structured and arranged at the center of the frame rail towards the upper face of the rail, to connect an external hoist for lifting in vertical direction. The lifting system as described above provides an easy lifting mechanism for heavy objects, such as an alternator of the electric drive trucks.

Abstract: A tool for installing a ring seal within a groove is provided. The groove is disposed within an inner diameter of a flange. The flange has an outer flange portion extended radially outward from the groove. The tool includes a rod and cylinder assembly defining a longitudinal axis along a centerline of a rod of the rod and cylinder assembly. A trigger mechanism is coupled to the rod and cylinder assembly. A flange engagement assembly is attached to the rod and cylinder assembly. The flange engagement assembly includes a main frame having a first end attached to the rod and cylinder assembly and a second end aligned with and extended along the longitudinal axis. A seal installation attachment is removably attachable to the second end of the main frame and structured and arranged to selectively overlay the inner diameter of the flange.
