2.3.4.3 Idler Gear #16
Inspect the Idler Gears for any worn, damaged or sharp/pointed teeth, or
worn bushing flanges (the thickness of the flange or the lip should not be
less than 0.050"). Check the Idler Bushings #17 for looseness. If the
diameter of the
inside wall
of the Bushing is
greater than 0.215"
, replace
the Bushing. Also, check the Thrust Washer #15 for wear (the thickness
of the washer should not be less than 0.050") and replace if necessary.
2.3.4.4 Idler Shaft #18
Examine the Idler Shaft for damage or wear (scoring) and replace if the
outside diameter
of the Shaft is
less than 0.196"
. The original O.D. of
the Shaft is 0.200" ±0.001".
2.3.4.5 O-rings #9, #19 & #21
Inspect the O-rings #9, #19, and #21 for deterioration (they have become
hardened or deformed) or damage and replace if necessary.
2.3.4.6 Output Pinion Bearing #7 and Seal #12
If the Output Pinion Seal #12 needs replacement (the seal is loose (it
should not be able to be rotated in the bore without any resistance) in the
Gearbox Nose bore or if the sealing lip has worn smooth), carefully pry
the Output Pinion Seal #12 out of the Gearbox Nose. Check the Seal #12
for wear or damage and replace if necessary. The Carbide Bearing #7
should not be loose in the Gearbox Nose. Replace the Bearing if it is
cracked or worn.
Check the Input Shaft Seal #11, in the bottom of the Output Pinion, for
wear and replace if the I.D. of the seal is worn smooth.
2.3.4.7 Rotor Shaft Upper Bearing #20 & Lower Bearing #13
Check both Bearings for wear, damage or looseness. If the
inside
diameter
of either Bearing is
greater than 0.190"
or either Bearing is
cracked, they should be replaced.
To replace the Lower Bearing, insert a small rod (with an O.D. of 0.200 to
0.250") in the Gearbox Nose, support the Gearbox Nose on its thick base
(the base that has four holes) against the Arbor Press base, and carefully
press the Bearing out with the Arbor Press. If the Bearing is extremely
tight and resists removal, lubricate the Bearing before pressing it out. If an
Arbor Press is not available, press the Bearing out by gently tapping the
small rod, above, with a Hammer.
