Assembly 1. If replacing the starter rope, see Step 8. LEFT-HAND KNOT RETAINING WEDGE (STEEL CLIP - NEW STYLE) Extreme caution should be used when working with springs. Always where appropriate safety equipment. 2. Install a new recoil spring if necessary by pushing the new spring out of the holder into the pulley cavity while aligning the outside spring hook into the deep notch in the pulley. Push the spring cover in until seated. STARTER HOUSING 3. Apply a small amount of lithium grease to the inner bore of the center shaft. STARTER PULLEY SPRING & COVER 4. Replace or check that both starter dogs are in the pulley pockets and that the dog springs are hooked on the outer surface of the dog. DOG SPRING STARTER DOG 5. Pinch the two legs of the plastic retainer together and start into the center shaft hole. 6. Rotate the retainer so the two tabs on the bottom of the part fit between the dog and pulley hub (left side of the dog). Push the retainer in until the leg prongs pop out of the center shaft. DOG RETAINER 9 7. Turn the starter over and snap the locking tab between the retainer legs, replace the top decal. NOTE: Refer to Service Bulletin 122 for steel locking clip. 8. Wind the starter pulley counterclockwise four or five turns to pre-load the recoil spring and thread the rope through the starter housing eyelet. Pull enough rope through to tie a temporary knot in the rope. Reattach the starter handle to the rope using a left-hand knot. Untie the temporary knot and allow the rope to recoil. STANDARD STAMPED STEEL AND CAST ALUMINUM STARTER (HM, VM) Disassembly Procedure 1. Untie the knot in the rope and slowly release the spring tension. HANDLE STARTER HOUSING REWIND SPRING AND KEEPER ASSY. 2. Remove the retainer screw, retainer cup (cam dog on snow proof type), starter dog(s) and dog spring(s), and brake spring (diag. 10). 3. Turn the spring and keeper assembly to remove the pulley. Lift the pulley out of the starter housing. Replace all worn or damaged parts. HANDLE INSERT ROPE PULLEY CAM DOG DOG SPRING STARTER DOG DOG RETAINER RETAINER SCREW Assembly Procedure 1. Place the rewind spring and keeper assembly into the pulley. Turn the pulley to lock into position. A light coating of non-freeze grease should be applied on the spring. WASHER BRAKE SPRING SPRING PIN 10 38
2. Place the pulley assembly into the starter housing. 3. Install the brake spring, starter dog(s), and starter dog return spring(s). The starter dog spring(s) must hold the dog(s) in against the pulley. On Snow King <strong>engines</strong> the starter dog posts should be lubricated with S.A.E. 30 engine oil. 4. Replace the retainer cup (cam dog on snow proof starter) and retainer screw. Tighten to 65 - 75 in. lbs. Older models that use a 10 - 32 retainer screw can be replaced with a larger 12 - 28 screw (part # 590409A). Re-drill the screw hole using a 13/64" (4.35 mm) drill bit. The center screw torque on cast aluminum starters is 115 to 135 in. lbs (13 - 15 Nm) (diag. 11 & 12). 5. Add-on alternator starters must have the center tubular rivet replaced each time the tubular rivet is removed. The tubular rivet should be pressed to a depth of 1/4" (3.175 mm) from the top of the starter housing. Skip this step if not applicable. 6. Apply tension to the recoil spring by winding the pulley counterclockwise until it becomes tight, then allow the pulley to unwind until the hole in the pulley lines up with the rope eyelet in the starter housing. Install a knotted rope through the pulley and the eyelet and install the handle. A left-hand knot should be tied on the end of the rope to secure the handle.

If a centering pin is used, be sure to align with the crankshaft (bottom pin in center screw hole). Install nylon sleeve 1/8" (3.175 mm) onto pin. Position nylon sleeve in aligning recess in the crankshaft. START two mounting screws in blower housing 90 o apart. With sleeve centered in crankshaft, gently push the starter in place, tighten the two mounting screws, insert and tighten the other two screws.
