Introdução
Use this guide to remove wrapped-up fabric or string, clean the turbine chamber and lubricate the bearing in the classic front-motor canister vacuum. Follow it when the motor suddenly whines, stalls or refuses to turn after sucking in shoelaces, ribbons or similar debris. Clearing the jam and refreshing the bearing will restore power and prevent overheating without replacing any parts.
Ferramentas
-
-
Undo the two Phillips screws beside the cassette slot and set them aside.

Slide a screwdriver into the cassette opening and flex the internal latch downward.
-
Press in the small lamp window near the bag sensor to release the opposite latch and lift off the green cover.
-
-
-
Insert a thin blade through the hole beside the suction port to keep the outer shell from twisting.
-
Place a wooden or plastic handle into the suction opening, brace it on the bench and pull the green shell straight off the cream body.
-
-
-
Pull the lower spade connector off the motor terminal.
-
Unplug the second lead at the push-on connector on the chassis.
-
-
-
Lift the motor straight up and out of the case.
-
Unscrew the white pre-filter plate and shake or blow the trapped dirt out of the cavity.
-
-
-
Undo the Phillips screws around the aluminium turbine housing and lift the housing off.
-
Stand the motor upright and tap the shaft with a wooden or plastic drift to drop the turbine wheel off the spindle.
-
-
-
Cut and peel away any melted tape, stockings or strings wrapped under the turbine using a sharp utility knife.
-
-
-
Lever the plastic cooling fan straight off the rotor with two screwdrivers.
-
Squeeze the tabs on each brush holder and withdraw the carbon brushes.
-
-
-
Loosen the two long screws at the shaft end so grease and dust can fall out of the threads.
-
Tap the threaded end of the shaft with a light hammer to free the rotor and slide it out of the stator.
-
-
-
Lift the bearing housing from the end cap and note the felt dust seal that stays inside the cap.
-
Slide the thin washer off the shaft and keep it safe.
-
Carefully pry up the rubber bearing seal with the utility knife tip without scratching the race.
-
Wipe out the dried grease completely.
-
Press the rubber seal back flush and clean off excess lubricant.
-
-
-
Seat the greased bearing and washer onto the shaft and slide the rotor back into the stator.
-
Install the two short Phillips screws and tighten them evenly in an alternating pattern.
-
-
-
Insert each brush, compress the spring and clip the holder until it locks.
-
Spread the spring slightly so it cannot jump out of the slot.
-
Lightly oil the metal spacer ring and slide it back onto the shaft.
-
-
-
Screw the turbine wheel onto the shaft by hand; operating speed will self-tighten it.
-
Scrape or brush caked dust from inside the aluminium cover before refitting.
-
Place the cover and tighten its screws evenly.
-
-
-
Fit the three rubber vibration dampers with the rounded face toward the casing.
-
Lower the motor into the shell so the suction opening aligns and the milled shaft end protrudes about 5 mm.
-
Reconnect the leads exactly as in your photo and push the pressure tube back onto the bag sensor stub.
-
-
-
Slide the motor module into the coloured housing until the latches click.
-
Tap around the perimeter to level the joint and install the cover screws.
-
-
-
Hook the bag on one hinge, press the opposite side and seat the cassette flush with the seal.
-
Plug the vacuum in briefly and run it without a bag to verify the motor spins smoothly, then reinstall the bag and enjoy many more years of reliable cleaning.
