11. Remove output shaft from housing.
12. Remove needle thrust bearing from shaft or hous-

13. Reposition motor in vise. Clamp across ports as
shown. Do not clamp on side of housing. Excessive
clamping pressure on side of housing causes distor-
tion.
14. Remove cap screws from mounting flange. These
screws are assembled with Loctite to hold them in
place.
The screws will require 300- 400 in-lbs (11 Nm) of
torque to break loose and 100 in-lbs to remove. Do
not use impact wrench on Loctite screws. This could
result in rounded heads or broken sockets.
NOTE: If torque higher than given above is required to break
screws loose, apply heat according to following
instructions:
When heated, Loctite partially melts. This reduces torque
required to remove screw. Use small propane torch to
heat small area of housing where screws enters. Be care-
ful not to overheat housing and damage motor. Gradually
apply torque to screw with socket wrench as heat is
applied for 8 to 10 seconds. Continue turning screw until it
is completely removed.
15. Carefully remove flange from housing.
