A tool for removing and replacing a piston from a drum of an automotive transmission has a generally circular base including a first set of openings arranged, when the tool is placed on a drum of an automotive transmission, to be in alignment with rivets attaching the piston to the drum. A cutting element is inserted into each of the first set of openings for cutting the rivets to remove the piston from the drum for repair or replacement. A second set of openings in the base are offset from the first set of openings when the tool is placed on the drum. A drilling element is inserted into each of the second set of openings for drilling holes in the drum which are offset from the first set of openings for readily removably mounting the repaired or replacement piston to the drum at positions on the drum offset from the positions at which the rivets have been cut. A method for removing and replacing the piston from the drum is provided by use of the tool.

Installation of a bushing into the shift cable end of an automatic transmission, without replacing the entire shift cable end, is accomplished via a method that does not require the use of compression tools and maintains the axial alignment of the bushing with the shift cable end during installation, thus preventing deformation of the shift cable end and bushing during installation, and ensuring the proper coupling of the shift cable end and shift lever. In one particular embodiment of the invention, the bushing may be installed by radially compressing the leading shoulder of the bushing and passing the bushing through the shift cable end, then releasing the leading shoulder of the bushing so that it engages the shift cable end and secures the bushing in place. This can be accomplished by pressing a bushing into the cavity of a tool having a cylindrical member with a first side and a second side, a cavity within the first side of the cylindrical member, and an elongated member extending perpendicularly from the second side of the cylindrical member, inserting said tool into one end of the shift cable end and passing the leading shoulder of the bushing beyond and through the shift cable end, thereby releasing the leading shoulder of the bushing to expand and secure the bushing.

The driven pulley is disposed around an outer periphery of a rack shaft coaxially therewith, and is fitted onto the ball screw nut so as to be integrally rotatable with an aligning structure interposed therebetween. The aligning structure includes locking grooves formed on an inner peripheral surface of the driven pulley, mounting grooves formed on an outer peripheral surface of the ball screw nut and radially opposed to the respective locking grooves, and elastic members. Each elastic member has a pair of base parts and a spring part integrally formed between the base parts, is disposed in the corresponding mounting groove with the base parts spaced apart from circumferential side surfaces, and is disposed between the mounting groove and the corresponding locking groove such that the spring part is locked on inner surfaces of the locking groove in a radially compressed manner.

A method of assembling or disassembling a gear assembly (20) of a wind turbine (10), the gear assembly (20) comprising a first helical gear (28) and a second helical gear (24) configured for rotatable engagement with the first helical gear (28), the method comprising transmitting a control signal to cause: axial movement of the first helical gear (28) at an axial speed relative to the second helical gear (24) along a rotational axis of the first helical gear (28): and, rotational movement of the first helical gear (28) at a first rotation speed relative to the second helical gear (24) about the rotational axis of the first helical gear (28), wherein one of the axial speed and the first rotation speed is a predetermined speed, and the other of the axial speed and first rotation speed is determined in dependence on the predetermined speed, and wherein the control signal causes the axial and rotational movement of the first helical gear (28) to occur simultaneously to engage or disengage the first and second helical gears (28, 24).

A method for attaching a gear driving part of this disclosure includes a first step of inserting a positioning bolt (23) into a positioning hole (21) of a first gear from a front side, and then screwing the positioning bolt into a screw hole (24) of a fixation-side member to regulate a phase of the first gear with respect to the fixation-side member; and a second step of inserting a portion of the bolt protruding to a front side of the first gear into a hole (22) of the gear case, and meshing the first gear with the second gear while positioning the fixation-side member in a predetermined phase position of the gear case.

A nesting structure supports a differential case. The nesting structure includes a first support structure that supports the differential case. The nesting structure includes a second support structure spaced apart from the first support structure to define a support opening. The support opening receives a first shim and establishes a first orientation between the first shim and the differential case in which the first shim is non-parallel with respect to a first bearing surface of the differential case.

A device for mounting a ring gear of an epicyclic gear train, the ring gear including a front ring gear and a rear ring gear, the device including: a plurality of longitudinal guides; a front mounting forming a portion of circle, including: at least two holes for passing the guides; a plurality of first system for supporting and rotating the front ring gear relative to the axis thereof, movable between a first position in which the front ring gear is supported and can rotate relative to the axis thereof and a second position in which the front ring gear is not supported; a rear mounting forming a portion of circle, including: at least two holes for passing the guides; and a plurality of second system for supporting and rotating the rear ring gear relative to the axis thereof, movable between a third position in which the rear ring gear is supported and can rotate relative to the axis thereof and a fourth position in which the rear ring gear is not supported.

According to the present invention, a neat is in a state of being received, by nut receiving means. In this state, a ball-embedding nozzle is fitted into the nut so that a gap between the inner circumference of the nut and the outer circumference of the ball-embedding nozzle is uniformly formed around the entire circumference thereof. Balls are supplied into a screw groove of the nut via a ball supply path in the ball-embedding nozzle.

In a worm reducer, an elastic member urges a worm shaft housed in a housing toward a worm wheel. In a method for manufacturing the worm reducer, the elastic member is arranged in a recess formed on the inner face of the housing. Then, a jig is inserted into the housing, and the elastic member is compressed by the jig. In the state in which the elastic member is compressed by the jig, the worm shaft is inserted into the housing. Then, the jig is removed from the housing.

A method for assembling a carrier subassembly for use with a planetary gear train comprises inserting a gear so that the bore of the gear surrounds the bore of the carrier member, and aligning an assembly guide having a bore by engaging a portion of the assembly guide with an alignment feature of the carrier subassembly such that the bore of the assembly guide is aligned with the bore of the carrier member.
