Clutch installation apparatus

A lifting apparatus for raising heavy clutch components to facilitate mounting of the components to a bell housing, the bell housing having a plurality of apertures therein for receiving fastening members, said apparatus comprising:

• a mounting plate being removably mountable to the bell housing, said mounting plate having a first side edge, a second side edge, a top edge, and a bottom edge, said bottom edge having a generally concave arcuate shape, said plate having a front surface and a back surface, said plate having a pair of slots extending therethrough, said slots being positioned nearer to said bottom edge than said top edge, said slots being spaced from each other and positioned such that each is alignable with one of said apertures, wherein a pair of the fastening members may be utilized to secure said plate to the bell housing;
• a pair of posts being fixedly coupled to said front surface of said plate, said posts being positioned between said top edge and said bottom edge and spaced from each other such that said slots are generally between said posts, a longitudinal axis of said posts being substantially perpendicular to a plane of said front surface of said plate, said posts being cylindrical and having a free end located opposite of said plate, said posts having a circumferential groove positioned nearer to said free end than said plate;
• a pair of cylinders having a first end and a second end, a base section, a middle section, and an end section, wherein said base section abuts said first end, each of said base and middle sections having an outer surface, said base sections having a diameter greater than said middle sections such that a shoulder is defined at a juncture of each of said base sections and a respective middle section, each of said first ends having a bore therein extending to a juncture of said middle and end sections, each of said bores being adapted for receiving one of said posts such that said cylinders are rotatably positionable on said posts, a length of said bores being less than a length of said posts such that said free ends of said posts abut said juncture of said middle and end sections, thereby maintaining a space between said base sections and said front surface of said plate, each of said middle sections having a threaded hole passing therethrough from said outer surface to said bore, each of a pair of retainer members being removably insertable and threadably couplable to one of said threaded holes, each of said retainer members having a leading end and a trailing end, each of said threaded holes being located such that said leading ends may extend into said grooves thereby releasably coupling said cylinders to said posts while allowing free rotation about said posts, said trailing ends partially protruding outwardly from said outer surface of said middle sections when said leading ends extend into said grooves, each of said end sections having a square aperture extending therein and defining a female coupler for selectively receiving ratchet tools to be utilized to rotate said cylinders;
• a pair of splines, each of said spines being integrally coupled to one of said middle sections of said cylinders, each of said splines extending from one of said shoulders to a respective one of said end sections;
• a pair of spools each having an opening extending therethrough for receiving one of said middle sections of said cylinders, each of said openings having a notch therein for receiving said splines such that said spools rotate with said cylinders, each of said spools being selectively positionable along said cylinders between said base section and said trailing ends of said retainer members;
• a strap extending between and being fixedly coupled to said spools, said strap being removably wound about said spools;
• a pair of belts, each of said belts having a first end and a second end, each of said first ends being fixedly coupled to said plate, each of said first ends being positioned adjacent to one of said base sections of said cylinders and located nearer said top edge than said bottom edge, each of said belts having a length generally equal to a circumference of said base sections, said belts extending about and abutting said outer surfaces of said base sections such that said second ends are generally positioned adjacent to said first ends;
• each of said cylinders having a first rotational direction and a second rotational direction, wherein said first rotational direction is defined by an unwinding of said strap from said spools and said second rotational direction is defined by a winding of said strap about said spools;
• a biasing member being releasably attached to and extending between said second ends such that said belts are pulled taut against said base sections, said biasing member being contracted when said cylinders are rotated in said first direction such that said belts restrict rotation of said cylinders, said biasing member being expanded when said cylinders are rotated in said second direction such that said belts permit rotation of said cylinders;
• a pair of levers, each of said levers being rotatably coupled to said mounting plate and positioned adjacent to one of said first ends of said belts, each of said levers being positioned generally in a plane oriented substantially parallel to the plane of said front surface of said mounting plate, each of said levers having a handle portion and a cam portion, each of said cam portions abutting one of said second ends of said belts, each of said levers being rotatable in such a manner that said cam portions may selectively bias said belts away from said outer surface of said base sections such that said biasing member is expanded and permits a degree of rotation of said cylinders in said first rotational direction;
• a pair of couplers for removably coupling said strap to the clutch component, each of said couplers comprising a threaded J-shaped hook which may be threadably coupled to the clutch component;
• wherein each of said hooks having a first end and a second end, said first ends being threadably couplable to the clutch component, said second ends having a annular ridge for retaining said strap;
• a pair of guide pins, each of said guide pins being releasably extendable through the apertures in the bell housing such that a user may align the clutch component with the bell housing;
• and
• wherein the user utilizes the ratchet tool to rotate said cylinders in said first direction while rotating said levers such that each of said belts are biased away from said outer surface of said base portions thereby allowing the extension of said strap downwardly until couplable to said hooks;
• and
• wherein the user utilizes the ratchet tool to rotate said cylinders in said second direction such that the clutch component is raised upwardly into a mating position with the bell housing.
