Drive Pulley Installation
(Figure 13)
Invert gear stand. Install drive pulley and split taper
bushing on vertical gearshaft. Make sure key and
keyways are aligned.
Tighten split taper bushing so dimension “B” (from the
centerline of the drive pulley to the center of the
gearbox stand mounting hole) is 1-15/16”. This is a
reference dimension and may require adjustment.
When gear stand is installed on mower, dimension “A”
(from the top of the mower deck to the centerline of the
drive pulley) must be 1-27/32” (plus or minus 1/32”).
This is a critical dimension and must be held. Remove
gear stand and adjust drive pulley as needed. Add or
subtract shim washers under idler pulley to align with
drive pulley. Tighten gear stand hardware.
Fill gearbox half full of SAE 90W gear lube. Check
level after waiting five minutes to permit lube to work
through bearings and add lube, if necessary, until it is
half full.
Attach driveline to gearbox with shear bolt. Replace
snap ring. Replace driveline shielding and secure with
shield retainers.
