When ordering replacement parts
* Use paint code: TK=Black
** Wheels include two bearings. Use part # MWB when replacing bearings only.
Note: Optional wheel kits are available that include the bearings and wheel clutch
installed. Order part # 19085 for left wheel kit and part # 19086 for right wheel kit.
*** Wheel clutch must be installed in the correct orientation in order to operate
properly. Wheel clutch is installed correctly when wheels spin freely while
trimmer is moving forward without the engine running (wheels will have resistance
when trimmer is moving backward). One of the wheel bearings may need to be
removed prior to installing the wheel clutch. The wheel clutch has an arrow on the
side to indicate the “free-wheel” direction. Ensure clutch is orientated so the free-
wheel direction corresponds to direction the wheel will rotate while trimmer is
moving forward and press the clutch into the center of the wheel (interference fit).
Then replace the wheel bearing and install the wheel on the axle.
Important!
Rotate wheel in free-wheel direction while mounting on axle
(spin and push at the same time). Ensure both wheel bearings remain fully
seated in wheel during wheel installation and operation. Failure to do so may
cause damage to wheel clutch.
