worn or damaged parts. Assembly Procedure LEFT-HAND KNOT 1. Insert the rope through the starter pulley. 2. Assemble the gear, pulley, washer, and snap ring. 3. Place a small amount of grease on the center shaft, place the gear and pulley into position making sure the brake spring loop is positioned over the metal tab on the bracket. The rope clip must fit tightly onto the bracket. The raised section fits into the hole in the bracket (diag. 14 & 15). RECEPTACLE FOR RAISED SECTION MOUNTING BRACKET TAB MUST FIT INTO SPRING LOOP 4. Install the hub and hub screw. Torque the hub screw to 45 - 55 in. lbs. (5 - 6 Nm). A loose hub screw will prevent the rope from retracting. 5. Install the return spring if necessary. A replacement spring is installed by placing the spring and its retainer over the top of the pulley and pushing the spring out of the retainer into the pulley's recessed area. ROPE CLIP RAISED SPOT 14 BRAKE 15 6. Install the spring cover and the cover screws. 7. Wind the rope onto the pulley by slipping it past the rope clip. When the rope is fully wound on the pulley, wind the pulley assembly two additional turns to put tension on the spring. 8. Mount the starter on the engine making sure the top of the starter gear teeth are no closer than 1/16" (1.59 mm) from the top of the flywheel ring gear teeth. VERTICAL PULL STARTER, VERTICAL ENGAGEMENT TYPE ROTATE COUNTERCLOCKWISE Disassembly Procedure 1. Pull out enough rope to lock the rope in the "V" of the bracket. STRUT PIN 16 2. Remove the handle if necessary by prying out the small staple in the handle with a screwdriver. 3. Place the starter bracket on the top of a deep well socket that is large enough to receive the <strong>head</strong> of the center pin. Use an arbor press to drive out the center pin. 4. Rotate the spring capsule strut until it is aligned with the legs of the brake spring. Insert a nail or pin no longer than 3/4" (19.05 mm) through the hole in the strut so it catches in the gear teeth. This will keep the capsule in the wound position (diag. 16). 5. Slip the sheave out of the bracket. CAUTION: DO NOT ATTEMPT TO REMOVE THE SPRING CAPSULE FROM THE SHEAVE ASSEMBLY UNLESS THE SPRING IS FULLY UNWOUND. 6. Squeeze and hold tightly by hand the spring capsule 40
at the outer edge against the gear sheave. 7. Remove the retainer pin from the strut and slowly relieve the spring tension by allowing the spring capsule to rotate slowly under control, until completely unwound. The spring capsule can now be removed from the gear sheave. ORIGINAL INSTALLATION WITH STAPLE INSTALL NEW ROPE BY TYING LEFT-HAND KNOT LEFT-HAND KNOT Assembly Procedure 1. Feed the new rope through the hole and tie a lefthanded knot on the rope end. Make sure the rope and knot do not protrude from the knot cavity and bind the pulley rotation (diag. 17). 2. Wind the rope on the sheave assembly clockwise, viewing the gear from the gear side of the sheave. 3. Reinstall the brake spring, being careful not to spread the spring more than necessary. REINSTALL LEFT-HANDED KNOT PRY STAPLE OUT TO REMOVE OLD ROPE 17 4. Install the spring capsule, making sure the starter spring end hooks on the gear hub (diag. 18). 5. Wind the spring four full turns and align the brake spring legs with the strut as shown. Insert the pin in the strut (diag. 19). GEAR HUB STARTER SPRING END 6. If the starter is equipped with a locking or delay pawl and spring, make sure these are in place before grasping the gear and spring capsule assembly and sliding it into the bracket. Make sure the legs of the brake spring are positioned in the slots of the bracket. 7. Feed the rope end under the rope guide and hook it into the "V" notch. Remove the pin and the strut will rotate clockwise against the bracket (diag. 21). SPRING HOOKED ON GEAR HUB ROTATE SPRING 4 FULL TURNS 8. Insert the new center pin by pressing or driving the pin firmly in place. Reinstall the starter assembly on the engine (diag. 21). 18 19 STARTER HANDLE BRAKE ROPE PULLEY PAWL SPRING * SPRING ASSY.
