9. Using a 5 mm Allen wrench, install only the (3)
screws that secure the pinion shaft assembly as
shown below. Leave the longer locking screw (A) out
at this point.
NOTE
DO NOT install the longer screw (A). Installing the
longer screw will lock the snorkel tube and not allow for
backlash setting adjustment.
10. Torque the bearing cover retaining screws to
specification.

11. Rotate the snorkel tube counterclockwise using the
snorkel tool (PA-50231) until the snorkel gear and
pinion gear have ‘zero’ backlash.
NOTE
DO NOT overtighten the snorkel tube when backing it
out. At the 'zero' backlash position, you should still be
able to turn the snorkel shaft using your fingers, but it
will feel rough and may have some tight spots.
12. Look down into the transmission housing to see the
snorkel locking screw hole opening to reference your
starting point.
NOTE
If you have a hard time seeing into the hole, insert a
small Allen wrench, punch or screwdriver into the hole
to feel when the notch is aligned with the hole.
13. Slowly rotate the snorkel tube clockwise while
counting the number of notches passing through the
hole opening as you rotate the tube. Rotate the
snorkel tube to the 3rd notch from the ‘zero’
backlash position obtained in step 11.
14. Check the pinion shaft gear backlash again by feel. If
the pinion shaft gear lash appears to be too tight,
rotate the snorkel shaft clockwise to the next notch
(4th notch).
15. Once the backlash is set, apply Loctite
®
242™ to the
threads and install the locking screw to secure the
snorkel tube.
