 TM 55-1905-223-24-5
FIGURE 3-58. Pilot Bearing (PTO/SL-111).
REPLACEMENT
a.
If the driving ring (1) was removed, install it to the PTO adapter plate with the eight hex-head
capscrews and lockplates. Tighten the capscrews to 80 ft-lb torque.
NOTE
It is recommended after a new Power Takeoff has been assembled to an engine or
the bearings have been adjusted, to tap the shaft on the end with a lead hammer
to relieve any preloading that may result due to the resistance of the pilot bearing
when being pressed into the flywheel.
b.
Position the PTO clutch housing (4) against the engine housing carefully aligning the pilot bearing in its
bore and engaging the teeth of the clutch driving plate with the internal teeth on the driving ring.
c.
Secure the clutch housing (4) to the engine housing with 12 hex-head capscrews (2). Torque to 80 ft-
lbs. Tap the output end of the shaft with a soft hammer to relieve any preloading on the bearings.
