3.2.2 BLOWER DRIVE SHEAVE INSTALLATION INSTRUCTIONS:
1. Remove the right side belt shield and the 5/16 x 3 1/4 bolt that secures the shield to
the deck.
2. If you are mounting the Ultra Vac on a Lazer HP with serial number 220,000 or
higher, skip to step 3. For Lazer HPs with serial numbers 220,000 and lower, locate
and cut off the corners of the right deck reinforcement plates by measuring 2" down
from the top and 2" from the outside as shown in Figure 6. (This step provides the
required belt clearance.)
3. Remove the deck drive belt from around the right sheave.
4. Support the right mower blade so that it will not fall off when the right sheave nut is
removed.
5. Remove the right sheave nut, spring disk washer, and drive sheave from the spindle
shaft.
NOTE: On units with wrench flats on the spindle just above the blade use a 1-
inch wrench on the flat sides of the spindle shaft to prevent the spindle from
turning. On units that do not have a wrench flat, block the blade rotation with a
block of wood between the blade and baffles as indicated in the blade service
section of the Lazer operator's manual. Do not use the blade bolt to prevent
rotation.
6. Apply a light coat of grease to the top portion of the spindle where the sheave
mounts.
7. Install the double sheave (Item 23) onto the right spindle shaft. Install the spring disk
washer and nut removed in Step 5. Torque the sheave nut to 75-80 ft. lbs. Make
sure that the spring disk washer cone is installed towards nut. See Figure 7.
NOTE: On units with wrench flats on the spindle just above the blade use a 1-
inch wrench on the flat sides of the spindle shaft to prevent the spindle from
turning. On units that do not have a wrench flat, block the blade rotation with a
block of wood between the blade and baffles as indicated in the blade service
section of the Lazer Z operator's manual. Do not use the blade bolt to prevent
rotation. Check blade bolt torque after completing this installation (115 – 120 ft.
lbs.).
