Husqvarna Lawn Mower Repair – Replacing the Wheel Dust Cover (Husqvarna Part # 581840401)

The wheel dust cover helps to keep dirt and
grass clippings away from the wheel gears and bearings. The plastic cover fits onto the drive shaft
bearing and axle housing, and encloses the back of the wheel. Over time, the dust cover can wear a hole
in it or be cracked and torn. This can allow dirt inside, which will quickly
wear away the gears and bearings. Replacing the wheel dust cover is a repair
that you can do yourself, and I’m going to show you how. Advertisement: Hi, I’m Mark Sodja. Do-it-yourself repairs like these are easier
than you might think. From lawn machines to cordless drills, kitchen
mixers, outdoor grills, our how-to videos walk you through each repair from start to
finish, so doing it yourself means never having to do it alone. Let’s get started. Mark: I’ll begin by removing the front wheel. I’ll use a 2×4 to prop the lawnmower up. I’ll remove the wheel nut, and then slide
the wheel away from the axle. I’ll remove the large washer behind the wheel. Now, remove the retaining ring that secures
the pinion to the transmission shaft. With the retaining ring removed, I can pull
the pinion away from the shaft and remove the pawl. Now, I can remove the dust cover. Now, I can install the new dust cover. I align it with the axle and the bearing,
and slide it into place. Now, I’ll reinstall the drive pawl. One end of the drive pawl has a shoulder to
hold it in place. I’ll insert the pawl into the opening in the
shaft, and the shoulder sits against the shaft. Now, reinstall the pinion gear. I align the slot in the back of the pinion
gear with the drive pawl. You never want to grease the drive gears because
the grease will attract dirt, which will quickly wear away the pinion gear, and especially
the plastic gear on the back of the wheel. Now, re-secure this assembly with the retainer,
and I’ll reinstall the large washer. I’ll finish up by reinstalling the wheel. That’s how easy it is to install a new wheel
dust cover on your lawn mower. Advertisement: Be sure to check back often
