If using covers:<br />
• Make sure the mating surface of the cover and retaining<br />
nuts are clean and dry.<br />
• Urethane cover: slightly roughen the mating surface<br />
of the cover, place a 3 mm – 6 mm ( 1 ⁄8 in. – 1 ⁄4 in.) bead<br />
of polyurethane adhesive sealant on the roughened<br />
surface.<br />
• Steel cover: place a 3 mm – 6 mm ( 1 ⁄8 in. – 1 ⁄4 in.) bead<br />
of silicone adhesive sealant on the mating surface of<br />
the cover.<br />
• Align the cover mounting holes with the mounting holes on<br />
the retaining housing nut (make sure that the grease fitting<br />
on the cover is accessible when doing so).<br />
• Apply and tighten the cover mounting hardware.<br />
