⁽¹⁾	The lubricant capacity will vary depending upon the housing mounting angle. The capacity given is for an angle of 4 degrees. A lubricant level close enough to the bottom of the fill hole to be seen or touched is not sufficient. The lubricant must be level with the fill hole.

⁽²⁾	Establish the pinion bearing preload prior to pinion seal installation.

⁽³⁾

The acceptable backlash tolerance is +/- 0.0508 mm (0.002 inch) from the backlash etched in the differential ring gear. The tooth contact pattern can move only by adjusting backlash. The tooth contact pattern can move only in the direction of heel-to-toe, and toe-to-heel. Depth of the tooth contact pattern is not adjustable. Contact Spicer Service at 1-800-666-8688 for assistance if you are unable to establish an acceptable tooth contact pattern within the limits of backlash.
