Abstract: An apparatus, method, and system for aligning at least one injector body to be installed into an engine block along a first direction. The alignment apparatus includes a first alignment member configured to swing between a clearance position and an alignment position, wherein the first alignment member is configured to align the at least one injector body along a second direction when in the alignment position. The apparatus further includes a second alignment member configured to align the at least one injector body along a third direction by contacting the at least one injector body via a first and second contacting portion.

Abstract: A submersible pump test bench capable of testing multiple lengths of submersible pumps. The test bench includes a series of trolleys that may be moved along, added to, or removed from a rail depending on the length of submersible pump to be tested. The test bench further includes a hose handler for redirecting a length of hose connecting the submersible pump to a broader hydraulic circuit. In certain embodiments, the hose handler includes a rotating sheave or similar structure that redirects the hose back on itself, providing a length-multiplying effect.

Abstract: A method of inserting an injector in a test head includes inserting the injector in a puck; aligning the puck beneath the test head; engaging a bottom of the puck with a floating cone assembly; raising the puck upwards towards the test head; and inserting a top portion of the injector into the test head. The floating locator cone assembly includes a floating locator cone mount; a ball thrust bearing assembly inserted in the floating locator cone mount; and a floating locator cone inserted in the floating locator cone mount on top of the ball thrust bearing. Use of the floating locator cone assembly allows the puck to center itself thereby allowing the injector to be properly aligned upon insertion in the test head. Proper alignment of the injector reduces false leak test readings and the consequent rejection of good injectors.

Abstract: A tester 10 suitable for testing fuel system components of an automotive vehicle such as a fuel pump 34, a fuel sender 36 and a pressure transducer 38 has a housing 12 that is coupled to a power supply 30. Switch SW1 is used to selectively power the fuel pump 34. A second switch SW2 is used to selectively couple power to transducer 38. A final test port TP1 and a second test port TP2 are places where the electrical characteristics of the fuel system components may be measured. For example, the sender resistance and transducer output voltage may be measured.

Abstract: A tool for tuning an engine having a fuel injector unit with a follower and a body with a flange portion protruding outward from the body, includes a support structure having a follower contact surface, a plunger member slidably connected to the support structure, for bearing against the flange portion, a light source connected to a power source, a circuit for delivering electric current from the power source to the light source, and a switch which closes the circuit when the plunger member is moved to a predetermined position, and opens the circuit when the plunger member moves out of the predetermined position. The support structure preferably includes a tubular housing having two ends and which receives the plunger member in one end. A spring is preferably provided for biasing the plunger member in an extended position relative to the support structure. The follower contact surface preferably includes an outward projecting arm member, including a plate having a recess for receiving the top of the follower.

Abstract: The need for engine maintenance is determined from valve stem wear by placing a cavity-containing housing of predetermined height on the cylinder head so that an exhaust valve stem on the cylinder head extends through the open bottom end of the housing into its cavity. A height measuring device, such as a depth micrometer, is supported on the top end of the housing and extends into the cavity of the housing until it contacts the top of the exhaust valve stem. At this point, the reading on the height measuring device indicates the distance between the top of the exhaust valve stem and the top of the housing. By subtracting this distance from the known height of the housing, the height of the exhaust valve stem can be calculated. By comparing the height of the exhaust valve stem when the engine is new to its height as periodically measured after the engine has been used, the increased height or "tulip condition" of the valves can be diagnosed, indicating the need for engine maintenance.

Abstract: A gauge for determining the proper formation of an annular recess formed at the bottom of a blind bore in the body of a hydraulic lash adjuster. A shaft having a tapered end is mounted in a block and an expandable, cylindrical gauging member is received over the tapered portion. A cylindrical sleeve is received over the shaft and is biased into engagement with the gauging member by springs acting between the block and the sleeve. When this assembly is inserted into the lash adjuster body and the gauging member contacts the bottom of the bore, continued axial movement of the shaft causes the gauging member to expand into the recess as the tapered portion of the shaft moves through the gauging member. Measurement of the amount of movement of the shaft provides an indication of the radial movement of the gauging element by virtue of the tapered interconnection.

Abstract: A method and apparatus for adjusting valves in automobile engines which utilizes an elongated indicating stick having a first set of indicia for identifying the specific valves to be adjusted with the engine in a first position, and a second set of indicia for indicating the particular valves to be adjusted following rotation of the engine one full turn in the normal direction of rotation.
