Figure 11-38. Exploded View of Starting Motor (PA-28R-201T)
c. On PA-28R-201 airplanes, no lubrication is required on the starter motor except at the time of
overhaul. Then lubricate the entire shaft under Bendix drive, fill grooves in armature shaft at drive end
and pack gear box with 1.3 to 2.0 ounces of lithium soap base grease No. 1925 Molytex “O” or
equivalent.
On PA-28R-201T airplanes, no lubrication is required on the starting motor except at the time of
overhaul. 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 777 on the drive end of the armature shaft before and
after installing the drive end head.
d. The starting motor should be operated for a few seconds with the ignition switch off. This is to
determine that the starter engages properly and that it turns freely without binding or excessive noise.
Start the engine two or three times to check the starter drive assembly.
NOTE
Refer to Bendix for service information concerning the starter drive
mechanism.
11-51. OVERHAUL. If during the above inspection any indication of starting motor difficulty is noted, the
starting motor should be removed from the engine for cleaning and repair.
11-52. REMOVAL. To remove the starting motor from the engine, first disconnect the ground cable from the
battery post to prevent short circuiting. Disconnect the lead from the starting motor terminal, then take out the
mounting bolts. The motor can then be lifted off and taken to the bench for overhaul.
