TRANSMISSION ASSEMBLY / SNORKEL
GEAR BACKLASH
SNORKEL GEAR BACKLASH
1. Reassemble the snorkel tube and snorkel shaft.
NOTICE
Failure to press the gear back against the washer and
retaining ring will lead to a gear backlash change after
vehicle is placed into service.
2. Apply a small amount of white lithium grease or Anti-
Seize on the threads of the snorkel tube. Install front
output shaft/snorkel tube into the gearcase using the
Snorkel Tube Tool. Bottom out the snorkel tube to the
transmission case.
Snorkel Tube Tool:
PU-51862
3. Install the pinion shaft assembly. Be sure to properly
mesh the snorkel shaft bevel gear with the pinion
shaft bevel gear.
NOTICE
Do not install the long bolt at this time or you will not be
able to see the windows on the snorkel tube to properly
set backlash.
4. Apply Loctite ® 242 ™ to the threads of the bearing
cover retaining screws. Install the screws and torque
to specification.
TORQUE
Bearing Cover Retaining Screws:
10 ft-lb (14 Nm)
5. Install the RH case half and install three case screws
to properly hold the case and shaft in the proper
location.
IMPORTANT
Installing the case halves together ensures the pinion
shaft is squarely aligned. Failure to perform this step
will lead to incorrect backlash being set.
6. Rotate the snorkel tube counterclockwise using the
snorkel tool until the snorkel gear and pinion gear
have ‘zero’ backlash.
NOTICE
DO NOT overtighten the snorkel tube. 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.
7. Look down into the transmission housing to see the
snorkel locking screw hole opening
k
to reference
your starting point.
NOTICE
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.
8. 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.
9. 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).
10. Once the backlash is set, apply Loctite ® 242 ™ to the
threads and install the locking screw to secure the
snorkel tube. Torque the locking screw to
specification.
TORQUE
Snorkel Locking Screw:
10 ft-lb (14 Nm)
TRANSMISSION ASSEMBLY
NOTICE
The snorkel shaft and pinion shaft must be installed
prior to transmission assembly. The snorkel shaft
cannot be installed after assembling the transmission.
IMPORTANT
Thoroughly clean the mating surfaces of the
transmission case halves so they are free of 3 Bond
sealant. Failure to properly clean the surfaces may lead
to transmission case leaks.
