16. Inspect gear teeth for wear or indications of fatigue, e.g.
hairline cracks at the root of the tooth. If one element has
undergone severe wear or broken teeth, replace the mating
element also.
17. Clean and inspect bearings for wear. Lubricate with light
oil before spinning to avoid scoring of working surfaces.
Remove any worn bearings with a wheel puller. If tapered
roller bearings are being replaced, drive the bearing
cups out of the housing base and cover, Ref. #10. DO
NOT use new cone assemblies with worn (old) cups.
18. If gears are to be replaced, use a wheel puller or press to
remove gears Ref. #1A4 or 4A4 from their shaft. Exercise
caution to avoid scoring shaft seal diameter with the keyway
in the gear.
19. Inspect all fasteners for damage or wear and replace with
fasteners of equal grade. Grade 5 fasteners
have three (3) radial lines on the head.
Fasteners are available in kit form, Ref. #80.
20. If the shaft assemblies can be reused intact
(no new parts required), refer to Section III,
Steps 6 thru 8, for reassembly procedure. Replace all
shim-gaskets with new parts, Kit Ref. #100. Use the same
thicknesses as removed during disassembly.
Identifying & Ordering Parts
1. Refer to the parts diagram, Figures 14 or 15, and make a
list of the parts required by part reference number. For
example, Ref. #21, 23, 100, 1A, 2A1, and 2A2. When a
gasket joint is separated, always replace with new
shim-gaskets. Order Ref. #100 shim-gasket kit.
2. Now refer to the parts list, Table 11, and determine the part
description and Falk part number using the part reference
number (Step 1) and the drive identification (e.g. 4407J25)
in the column headers of the parts list.
3. Use the part description and Falk part number to order the
required parts. In the examples of preceding Steps 1 and 2,
Ref. #21, 23, 100, 1A, 2A1 and 2A2 for a 4407J25, parts
would be ordered as follows:
Ref. #21 — Seal cage · · · · · · · · · · · · 4723117
Ref. #23 — Seal· · · · · · · · · · · · · · · 0912913
Ref. #100 — Shim-gasket kit · · · · · · · · · 4723120
Ref. #1A — Shaft assembly with gear · · · · · 4723133
Ref. #2A1 — Bearing · · · · · · · · · · · · 0921780
Ref. #2A2 — Bearing · · · · · · · · · · · · 0921780
4. Tables 12 and 13 converts Falk part numbers to bearing and
seal manufacturer’s part numbers. Tooth combinations are
listed in Appendix H.
5. Place your order with your local Falk Distributor. If you need
to locate a distributor, phone (414) 342-3131.
Recommended Spare Parts
1. For non-critical drive applications a complete set of
bearings, seals and shim-gaskets is recommended. If stored
in their original packaging in a dry, cool location, these
parts have a minimum shelf life of 5 years.
2. For critical drive applications (where an outage would create
a major production loss), a complete drive is recommended.
