INSTALLING THE TAPERED BEARING ADAPTER
4. The tapered bearing adapter has
a tighter press fit into the
transmission case than the stock
bearing. To ensure successful
installation of the tapered bearing
adapter and longevity of the
installation tool, you must heat the
transmission case as shown in
figure 11. Use a MAP/propane
torch or a heat gun as shown in
figure 12.
5. Apply heat evenly around the boss
of the main drive gear bearing bore
from the outside of the case as
shown in figure 14. DO NOT heat
the boss from the inside of the case
and keep heat away from the
tapered bearing adapter that is
staged and ready for installation.
The bearing bore boss should be
heated to at least 200°F. BAKER
recommends using an infrared
thermometer to verify that the case
is adequately heated; see figure 13.

MAIN DRIVE GEAR BEARING BOSS AREA
FIGURE 12 | USE MAP/PROPANE GAS
OR A HEAT GUN TO HEAT THE CASE
FIGURE 13 | USE AN INFRARED
THERMOMETER TO VERIFY THAT THE
CASE IS HEATED TO AT LEAST 200° F
BERT TIP:
You may see some discoloration
where the case is heated.
Restore color by rubbing a little
bit of WD-40
®
or another thin oil
into the powdercoat.
