C13) Press in and rotate the outdrives against
each other and the diff balls, then screw
the thrust bolt a turn or two and rotate the
outdrives again. Doing this helps seat the
diff components as you tighten things
down. Continue to screw in the thrust bolt
and rotate the outdrives until the bolt is
finger tight. Notice as you screw in the
thrust bolt the T-nut (arrow) is moving
deeper into the outdrive toward the center of the diff. This compresses the diff
spring. When the T-nut reaches the bottom of the outdrive slots the spring is fully
compressed.
Do not overtighten the thrust bolt!
The little 2-56 bolt breaks easily,
or the “ears” will rip off the T-nut. Some gorilla drivers have actually put flat spots
on the diff balls! Now back off the thrust bolt 1/8 turn and you’ve got a good
starting point for diff adjustment.
C14) Carefully wipe any excess diff lube from
between the outdrive and underside of the
diff gear on both sides. Again, excess
lube only attracts dirt. Last, remove the
diff cover from the tree, trim it carefully –
don’t cut off the “ears”! – and push it in
over the head of the thrust bolt concave
side down to keep dirt out of the thrust
bearing assembly.
That’s it, the diff is done. Took longer for us to write than for you to do!
