Clutch bearing seizure is usual with this lawn mower, resulting in the mower no disengaging with the PTO switch. Beforehand signs may be intermittent or may appear upon beginning the engine after the unit has actually not run for a while. Here room a couple quick tests to verify the problem: First, through the ignition on, activate the PTO switch because that the electro-magnetic clutch and a distinct click must be heard if the unit engages. This is strong evidence over there is no electrical difficulty from damaged or non-contacting wires. The 2nd test is to check the deck drive wheel for rotation once the PTO is switched off. To get rid of other causes such as drag indigenous the blades or belts, relax the mower belt tension lever in former of the appropriate rear tire. (CAUTION: this spring-loaded lever can be a finger smasher.)
Now, shot to turn the pulley-block by hand.
If the immobile, the bearing is probably seized.
The just other opportunity is that the air gap between the armature and the rotor has decreased or has become fouled, however this is very unlikely due to the fact that the friction instead tends come wear the faces to widen the gap and also the rotation self-cleans this space.Reports indicate this bearing is difficult or impossible to replace, but it’s fairly simple. Remove the entire electric clutch by first removing the bolt and washer indigenous the bottom of the journey shaft and also then wedging and also rocking the clutch through a couple large screw motorists to work-related it under the shaft. An impact wrench is not essential if the starting ring equipment is accessed with the air cleaner access port and also a big bladed driver is inserted in between cogs on come immobilize the journey shaft. Keep a mental picture of just how the clutch is positioned together it’s removed. That not possible to change it incorrectly, but it can make the job really tedious if that mispositioned.At a workbench, eliminate the bearing retainer clip and also the nuts native the 3 adjustment bolts. Then ar the unit on a certain surface, preferably wood, and insert a socket around the very same size or a little smaller 보다 the I.D that the bearing and start whacking it with a hammer to drive the sleeve down. The springs against the force of striking and also the shaft gradually “sinks away” together the pulley-block rises. An alternative is to location the unit over an opening and also suspend the wheel with a pair of stole straps and pound the column out of the wheel in prefer manner, or a press could be supplied if one is available.View attachment 330322This section of the brake plate i do not care detached, so save the springs now. If the bearing is rusted in, a 50:50 mixture that acetone and automatic transmission liquid is excellent for releasing frozen contents (this mixes prefer water and also oil, for this reason shake well while applying.) apply it continuously for a day or two if crucial until the bearing and also sleeve have the right to be pushed out.The bearing essential is a 6206 DU and also it expenses ~$10 at a regional bearing supplier. Clean the bearing receptacle, the sleeve, and also the encounters of 2 clutch plates before replacement continues. Even if it is you push or pound the bearing, it’s important to usage “bearing etiquette” by always applying pressure evenly end the entire bearing so over there aren"t uneven or focal forces on the balls and also races. I supplied this big spacer washer that extended both the internal and external races, but a block of wood would job-related similarly.
Reinstall the 3 springs prior to realigning the separated pieces of the clutch with the pulley and also bearing top top the shaft sleeve the the other portion of the clutch and, when on the firm surface ar with a equivalent block under the contrary bearing to support it throughout impact, tap or press them together. Through a small care, the bearing inserts easily. Tighten the nuts to about their original extent for starters, then use a feeler gauge with the 3 slots to adjust them to leaving 0.015” wait gap. Execute this repeatedly because tightening one transforms the space with the others. In ~ this allude the brake duty of the clutch is engaged and you won’t have the ability to turn the pulley. But before installing, it deserve to be experiment by temporarily reconnecting the wires, energizing the PTO switch, and the pulley should rotate.Replacing the clutch is the most daunting part the the process. Remove the deck with the tractor up on jacks facilitates much better accessibility, however in the time it bring away to do all the it deserve to replaced with the deck on. Do a mark out to the sheet of the wheel in line v the keyway help to align the key, return the sleeve cannot be rotated without dropping it turn off the column again. When the clutch can be started up the tower correctly, ar a jack under it to host it temporarily and also then rotate the triangular plate come align the slot with the positioning pin toward the rear of the tractor. Through a washer or block top top the jack come guard the bearing again, start jacking the wheel onto the shaft while tapping and also wiggling as you go. Download the bolt and also tighten making use of the screwdriver in the cogs together before and then reconnect the electric clip in the right frame channel.

The inaccessible hanger because that this clip deserve to be changed by threading a zip-tie with its hole and around the frame.
Take it out for a test drive and also it have to be ready to mow lawns.
