Your local Jd dealer can get you service guard tool for that specific pulley or they can advise you on how to remove it. Some dealers may loan you the tool. Just depending on dealer.

Power steering pump requires power steering puller and has to be pressed on with the same tool you can rent from Oreilly s or Auto Zone. If it is a harmonic balancer it requires its own type puller. Every component has its own special puller.

Hub & Bearing Removal & Installation To Remove:
Hub bearing assembly (Typical)

1. Release parking brake.
2. Remove rear wheel assembly.
3. Remove rear wheel speed sensor from carrier.
4. Dismount brake caliper and support with mechanic's wire.
5. Remove brake disc.
6. Remove 4 axle hub mounting bolts. Special tool 09432-11000 (Typical)
   
   
7. Using tool 09432-11000 (or suitable gear puller), remove tone wheel.
8. Remove carrier.
9. Remove stakes and remove flange nut.
10. Support bearing outer race flange and press rear axle hub out.
11. Using tool 09432-11000 (or suitable puller), remove inner race from axle hub.

To Install:
Hub bearing assembly (Typical)

1. Apply thin coat of grease to bearing contact surface and hub.
2. Using and appropriate tool, press bearing into hub. CAUTION
   Do not press against outer race of wheel bearing.
   
3. Install flange nut and stake nut until it meets concave portion of spindle.
4. Install carrier.
5. Use an appropriate tool to press tone wheel.
6. Install hub/bearing assembly with rounded portion of outer race facing up.
7. Install 4 hub/bearing assembly bolts and rotate hub to seat bearing.
8. Measure wheel bearing starting torque with a spring balance or equivalent device.
   • Starting torque should measure 15.9 in lb (1.8 Nm) or less
9. Install brake disc.
10. Mount brake caliper.
11. Install rear wheel speed sensor to carrier.
12. Install rear wheel assembly.

Remove the screw on cap and select the appropriate collet.
Place collet over hole in top of Impact Bullet Puller and screw cap on loosely.
Insert cartridge with a rotary motion until case rim seats against the collet, or the extractor groove engages the collet.
Tighten cap firmly.
Strike the Impact Bullet Puller against a hard wood surface, while holding the Impact Bullet Puller handle parallel to the surface and the Impact Bullet Puller head perpendicular to the surface at the time of impact.
This technique will give the maximum inertia to the bullet being pulled. Two or
three impacts should pull most bullets.
Never hit the Impact Bullet Puller on a steel or concrete surface. The best hard
surface to use is the "end grain" of a block of wood.
Check tightness of cap after each blow.
Remove cap, push case out of collet, and recover pulled bullet and powder

Six routines must be followed in order to minimize the chances of your hydraulic equipment suffering costly, premature component failures and unscheduled downtime: * Maintain fluid cleanliness; * Maintain fluid temperature and viscosity within optimum limits; * Maintain hydraulic system settings to manufacturers' specifications; * Schedule component change-outs before they fail; * Follow correct commissioning procedures; and * Conduct failure analysis.
