Spacer

1. Removed deck from Toro Z4200.
2. Impacted wrenched off spindle pulley nuts, removed pulleys.
3. Stood deck on it’s side and impact wrenched off the blades and tapped out spindle shafts.
4. Using drift punch and hammer knocked out both bearings from each of the spindle housing,
Spacers in between bearings might break due to the material made of.
5. Cleaned up inside of spindle housing, applied never seize compound to bearing bores,
Install one bearing, then a new spacer then second bearing. Might need to support the
spacer with the blade’s shaft to center it while installing second bearing in the spindle
housing. Used drift punch and hammer carefully on outer race to install bearings. Bearings
should be touching the spacer. You can try use an old bearing to place on the new bearing
to tap in place with hammer.
6. Install shaft, blade and pulley.
7. After reinstalling all components spin the rotating assembly hand and the rotation should be
smooth with no binding, like free-wheeling. If not recheck if parts are binding/touching the
housing in any way or a clearence problem between bearings. The metal spacer is needed
to take the tightening load off the bearings in the spindle housing.
8. Reinstall deck to mower and test.
