#Gray transmission jack 27mm free
The transmission jack 10 includes, as its primary components, a wheeled base 12 a lift arm 14 a load-receiving head 16 at the normally outermost free end of the lift arms a leveling assembly 18 coupled at one end with the base 12 and at the other end with the head 16 and means 20 for elevating the lift arm 14. 4 is a fragmentary, partially sectional side elevational view of the transmission jack. 3 is a fragmentary, sectional plan view of the leveling assembly andįIG. 2 is a fragmentary, side elevational view of the transmission jack įIG. 1 is a fragmentary top plan view of the transmission jack, parts being broken away to reveal details of construction įIG. Other objects including significant details of construction will become apparent from the following specification and accompanying drawings, wherein:įIG.
Yet another object of this invention is to provide a transmission jack having a base and a pair of legs extending therefrom, the legs being inclined outwardly with respect to the base whereby to present an open area beneath the head of the jack.

Additionally, the pumping circuit of the hydraulic unit has a built-in release valve which protects the jack from overloading due to manual effort on the pump handle. The fluid reservoir for the cylinder contains an anticavitation tube which precludes the unit from becoming air locked even though the pump which supplies fluid from the reservoir to the cylinder may be operated with the rear end of the jack elevated as is commonly done. It is a yet further aim of this invention to provide a transmission jack which is operated by a hydraulic power unit consisting of a piston and cylinder assembly coupled with a fluid reservoir, the piston having at its outer free end a transversely disposed guide member, which guide has rollers on each end thereof, the rollers being received in corresponding trackways on each side of the base whereby to minimize bending loads on the hydraulic cylinder.
In order to accomplish this result there is provided a wheeled base having a lift arm pivotally coupled at one end thereof to the base, the other end of the lift arm having a load-receiving head thereon, there being a leveling assembly interconnecting the head and the base of the jack whereby the head may be rotated about a transverse axis and thus positioned with respect to the vehicle when the transmission is to be supported by the head. It is the most important object of this invention to provide a jack for handling vehicle transmissions such as is normally done in service stations, automotive repair shops and the like, the jack being relatively simple in construction and operation whereby to greatly facilitate the handling of bulky and heavy vehicle transmissions as they are removed from or installed into the vehicles.
