Gear And Pinion Housing; Stall - Torque Hook-Up; Bendix Drive (Pa-28R-201); Assembly - Piper ARROW III Service Manual

11-58. GEAR AND PINION HOUSING. (PA-28R-201) Inspect housings for cracks and bearings for excessive
wear. Remove rust, paint or grease from mounting surfaces.
11-59. BENDIX DRIVE. (PA-28R-201) The Bendix drive should be wiped clean with a dry cloth. The pinion
should turn smoothly in one direction and should lock in the other direction. Replace drive if it fails to check
as above or if the pinion teeth are excessively worn or damaged.

11-60. ASSEMBLY.

a. On PA-28R-201, when assembling the starter motor, always use an arbor press and the proper bearing
arbor for installing graphitized bronze and roller bearings. The Bendix shaft should have a thin film of
Lubriplate No. 777 or equivalent on the Bendix portion of the shaft. End play should be .005 to .050 of
an inch.
On PA-28R-201T, when assembling the starting motor, always use a arbor press and the proper bearing
arbor for installing graphitized bronze bearings. Soak new absorbent bronze bearings in SAE 20 oil before
installation. Saturate the felt oiling pad in the commutator end head with SAE 20 oil. Allow excess oil to drain
out before installing end head on motor. Put a light film of Lubriplate No. 777 on the drive end of the armature
shaft before and after installing the drive end head.
b. New brushes should be properly seated when installing by wrapping a strip of 00 sandpaper around the
commutator (with the sanding side out) 1-1/4 to 1-1/2 times maximum. Drop brushes on sandpaper
covered commutator and turn the armature slowly in the direction of rotation. Dust should be blown
out of the motor after sanding.
The spring tension is 32 to 40 ounces with new brushes. This tension is
measured with the scale hooked under the brush spring near the brush and
the reading is taken at right angles to the line of force exerted by the brush
spring.
