Anleitung Zusammenfassung
e) Pack the bearings with a NGLI grade #1 multi-purpose grease. f) Insert (1) bearing, (1) new seal into the wheel. NOTE: Seals (Exmark PN 103-0063) must be replaced. g) If the axle assembly has had both spacer nuts removed (or broken loose), apply a thread locking adhesive to (1) spacer nut and thread onto the axle with the wrench flats facing outward. Do not thread spacer nut all of the way onto the end of the axle. Leave approximately 1/8” (3 mm) from the outer surface of the spacer nut to the end of the axle inside the nut. h) Insert the assembled nut and axle into the wheel on the side of the wheel with the new seal and bearing. i) With the open end of the wheel facing up, fill the area inside the wheel around the axle full of NGLI grade #1 multi-purpose grease. j) Insert the second bearing and new seal into the wheel. k) Apply a thread locking adhesive to the 2nd spacer nut and thread onto the axle with the wrench flats facing outward. l) Torque the nut to 75-80 in-lbs. (8-9 N-m), loosen, then re-torque to 20-25 in-lbs. (2-3 N-m). Make sure axle does not extend beyond either nut. m) Re-install the seal guards over the wheel hub and insert wheel into caster fork. Re-install caster bolt and tighten nut fully. IMPORTANT: To prevent seal and bearing damage, check the bearing adjustment often. Spin the caster tire. The tire should not spin freely (more than 1 or 2 revolutions) or have any side play. If the wheel spins freely adjust torque on spacer nut until there is a slight amount of drag. 4.1.17 Lubricate seat switch actuator: Service Interval: 160 hrs. a) Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake. b) Unhook seat latch and tilt seat up. 27 c) Lubricate switch actuator rod with spray type lubricant or light oil. 4.1.18 Lubricate brake handle pivot: Service Interval: 160 hrs. a) Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake. b) Lubricate bronze bushings on brake handle pivot with a spray type lubricant or light oil. 4.1.19 Lubricate brake rod bushings: Service Interval: 160 hrs. a) Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake. b) Unhook seat latch and tilt seat up. c) Lubricate bronze bushings on each end of brake rod shaft with a spray type lubricant or a light oil. Shaft is located under the console. 4.1.20 Lubricate motion control bronze bushings: Service Interval: 160 hrs. a) Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake. b) Unhook seat latch and tilt seat up. c) Lubricate bronze bushings on flange bearings securing the motion control arm shafts with a light oil or a spray type lubricant. 4.1.21 Remove engine shrouds and clean cooling fins: Service Interval: 80 hrs. a) Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake. b) Remove cooling shrouds from engine and clean cooling fins. Also clean dust, dirt and oil from external surfaces of engine, which can cause improper cooling. c) Make sure cooling shrouds are properly reinstalled. Operating the engine without cooling shrouds will cause engine damage due to overheating. 4.1.22 Check spark plug: Service Interval: 160 hrs. a) Remove spark plug, check condition and reset gap, or replace with new plug. See Engine Owners Manual. 4.1.23 Change fuel filter: Service Interval: As Required a) A fuel filter is installed between the fuel tanks and the engine. Replace when necessary. Briggs & Stratton P/N 493629 4.1.24 Change hydraulic system filter: Service Interval: After First 250 hrs. Then yearly thereafter NOTE: Use only Exmark Part No. 109-4180 for Summer use above 32° F (0°C) or Part No. 1-523541 for Winter use below 32° F (0°C). a) Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake. 28 b) Locate filter under left rear corner of engine deck. c) Carefully clean area around filter. It is important that no dirt or contamination enter hydraulic system. d) Unscrew filter to remove and allow oil to drain from reservoir. IMPORTANT: Before reinstalling new filter, fill it with Mobil 1 15W-50 and apply a thin coat of oil on the surface of the rubber seal. Turn the filter clockwise until rubber seal contacts the filter adapter then tighten the filter an additional 2/3 to 3/4 turn. e) Fill reservoir as stated in Section 4.1.10. f) Raise the rear of machine up and support with jack stands (or equivalent support) just high enough to allow drive wheels to turn freely. g) Start engine and move throttle control ahead to full throttle position. Move the speed control levers to the full speed and run for several minutes. Shut down machine and recheck oil level. Do not change hydraulic system oil (except for what can be drained when changing filter), unless it is felt the oil has been contaminated or been extremely hot. Changing oil unnecessarily could damage hydraulic system by introducing contaminates into the system. 4.1.25 Wheel hub - slotted nut t...
