Abstract: A pneumatic compressor assembly includes a frame and an actuator carried on the frame. The actuator includes a cylinder and a piston. A tool is secured to the end of the piston. The tool includes a cross rail and two sets of adjustable compression fingers.

Abstract: A cleaning and piston replacement kit for an accumulator of a vehicle transmission which includes a brush for cleaning, reconditioning and polishing worn accumulator bores and replacement pistons each of which includes a pair of sealing rings for supporting and spacing the replacement pistons from the accumulator bores to thereby prevent scrapping of the walls of the bores by movement of the pistons within the bores and a method of reconditioning the accumulator bore.

Abstract: Apparatus and method for extending the life of a booster valve in an automatic transmission. The booster valve commonly resides in the pump stator body and is modulated by reverse oil pressure and pressure control solenoid pressure signals. Pressure signals from the reverse oil pressure and the pressure control solenoid force a booster valve piston towards a pressure regulator valve piston also generally residing in the pump stator body. The booster valve piston slides inside a booster valve sleeve, and over time, the booster valve sleeve wears and the performance of the booster valve degrades or fails. The present invention replaces an original inner booster valve spring with a longer (or in some cases shorter) replacement booster valve spring to shift the operating range of the booster valve piston to an unworn portion of the booster valve sleeve to extend the life of the booster valve.

Abstract: A clamp of an anti-vibration spring includes a pipe body and a sheathing element fixed to an end the pipe body. Another end of the pipe body is fixed to a covering element. The sheathing element is passed through the external periphery of the pipe body. The pipe body includes a screw rod screwed at the moving element, and an end of the screw rod is protruded from an end of the covering element and fixed at a driving element. A connecting element between the sheathing element and the moving element positions the sheathing element and the moving element. Each sheathing element has a connecting portion including a transversal slot, two clamping disc, and an insert portion on the clamping disc connected to the transversal slot and fixed by a positioning element. By turning the driving element, the anti-vibration spring is compressed or released between the two clamping discs.

Abstract: The present invention relates to a method of producing cooling fluid discharge orifices in the wall (171) of a part manufactured by the technique of lost wax casting in which a pattern of the part is produced in a wax mold, the orifices having a first portion (110E) emerging at the external surface (171ext) of the wall. The method consists in making cavities in the wax pattern that correspond to the first portions (110E) of said orifices of the part. Thus it is possible to produce cooling air discharge orifices without sharp edges.

Abstract: A spring-compressor device comprises a body having at least two telescopic parts (1, 4, 7) fitted with respective coupling means (2, 9) for jaws (3, 10), and including means internal to the body for controlling lengthening or shortening thereof. The innermost part (7) of the body is constituted by the body of a single-acting actuator whose rod (11) which is secured to the piston (12) of the actuator is fixed to the outermost part (1) of the body and is provided with a duct (14) for feeding the chamber (13) of the actuator whose increase in volume tends to retract the body of the compressor.

Abstract: A transmission disassembly tool, for compressing springs biasing a retainer against a snap ring disposed on a hub within a rear piston casing of a transmission includes a rod passing through the hub and extending above and below the hub, a cap disposed on the retainer, a device for locking the cap on the rod above the hub, a pedal, a device for detachably connecting the foot pedal to the rod below the hub, and a device for pivotally attaching the pedal to any substantially vertical surface, whereby depression of the pedal pulls the retainer away from the snap ring, and a method for operating the tool.

Abstract: A rebuilding tool for an automatic transmission which has a table top mountable base (20) with front (22) and rear (24) legs upwardly extending, and a working platform (28) in between. An adjustable height extension member (34) is slideably connected within the rear leg (24) and contains cavities (36) on the sides to receive either a horizontal beam (46) or an offset beam (48) that extend above the platform (28). The extension member (34) is adjustable in height positioning the beam at the desired location with a selected one of a series of jigs (50), or fixtures (52) and (54), adjustably disposed on the end of the beam. This jig (50), or fixture, holds the workpiece in compression against the platform (28) and is individually adjustable by threaded rod compressing means (60) having a manually operated handle. The beam (46) or (48) that is not in use is stored in the remaining cavity (36) on the extension member ( 34).

Abstract: The improved transmission tools are adapted to compress springs forming parts of the front and rear servo assemblies of an automatic transmission, so that snap spring locks may be removed to permit removal of the assemblies from the transmission housing. The tools make use of holes which are already part of the transmission housing, and include parts which are freely inserted in such holes, but which bind in the holes when the tool is canted slightly so as to permit force to be applied to the respective spring to compress it and therefore permit removal of the respective snap ring lock.
