Vehicle transmissions have many complex parts including various springs with various purposes. A rebuilder using crude tools, or the installer's fingers may struggle with the installation. Further, the rebuilder could potentially be injured or cause damage if the spring is improperly released from a state of compression. Mechanical tools can simplify the installation process. But the availability and applicability of existing tools do not always fit the shape of the required installation. This application discloses a unique transmission spring compressor tool (slide spring tool), which allows a rebuilder to install transmission springs into a transmission. The slide spring tool includes two independent pieces: a body with a receiver configured to accept a plunger and a plunger assembly. The slide spring tool is adapted to compress a slide spring, receive the slide spring in the spring gap, and place the slide spring into a slide slot on an oil pump assembly.

A tool assembly designed to couple to a torsion spring and torsion rod to wind and unwind the torsion spring on the torsion rod. The tool assembly includes a variety of components in mechanical communication with one other to rotate the torsion spring. Specifically, the assembly includes a worm gear in mechanical communication with a ring gear and a set of brackets securable to a torsion spring. Between the ring gear and the brackets are a series of plates arranged and assembled on a base, providing a singular device within the assembly that a user can grip to manipulate a torsion spring in a safer manner than possible in the prior art. A drill or other device can couple to attachment points in mechanical communication with the worm gear to rotate the worm gear at a greater rate, thereby reducing the winding and unwinding time of the torsion spring.

Provided is a method for manufacture of a seat for a vehicle, comprising a step of setting a return spring in a clamp jig, a step of clamping and fixing the return spring in the clamp jig, a step of inserting the return spring which is clamped in the clamp jig in an attachment unit, and a step of removing the return spring from the clamp jig.

A shock compression tool has a first end assembly defining a main axis and a first engaging surface, a second end assembly the second end assembly defining second and third engaging surfaces. The second end assembly is supported for movement along the main axis relative to the first end assembly. A drive system displaces the second end assembly along the main axis relative to the first end assembly such that a distance between the first engaging surface and the second engaging surface may be altered, and a distance between the first engaging surface and the third engaging surface may be altered. The first engaging surface and the second engaging surface define a first reference line. The first engaging surface and the third engaging surface define a second reference line. At least a portion of the first reference line is spaced from at least a portion of the second reference line.

An apparatus to install or remove tension coil springs from spring seat. Apparatus spans beyond the length of a tension coil spring allowing connection to spring ends with a loop and or hook on a threaded shaft. Applying a turning force to threaded shaft will stretch spring to a longer length allowing removal of spring from spring seat. A turning force in opposite direction retracts spring to shorter length allowing installation of spring to spring seat.
