8.2.4 Transmission Disassembly and Inspection
w The planetary gear transmissions used in the AFC1200 System's tool assemblies are
designed to withstand the forces exerted upon them by the production requirements of
modern assembly plants.
w To prolong the life of the transmission assembly, the components must be inspected and
greased at regular intervals.
P. FEC INC. recommends performing this procedure initially after equipment has
been in use for one year or 500,000 cycles, whichever is reached first.
P. When the initial maintenance is performed, the condition of the transmission
assembly should be analyzed to determine future maintenance requirements.
Systems operating under more severe conditions may require maintenance every
500,000 cycles, while other systems may only require maintenance every
2,000,000 cycles. Maximum time between inspections should be one (1) year.
1. REMOVE TRANSMISSION FROM TOOL ASSEMBLY. Separate the transmission from
the motor by removing four (4) screws. Remove the snap ring from the output shaft.
Separate the transducer from the transmission by removing four (4) screws.
2. DISASSEMBLE TRANSMISSION. Refer to the appropriate transmission assembly
drawing while disassembling the transmission for cleaning.
3. CLEAN TRANSMISSION PARTS. Clean all parts with an appropriate solvent, such as
mineral spirits, to remove all excess grease and contamination. Parts should be carefully
wiped dry with a lint-free cloth to remove any residue. Allow the parts to dry thoroughly in
an area free from contamination.
4. INSPECT TRANSMISSION PARTS. Examine all gears, pins, bearings, etc. for signs of
excessive wear. Replace any part that appears it may fail.
5. LUBRICATE TRANSMISSION PARTS. Reassemble the transmission in a
contaminant-free area. Re-pack all bearings and grease all gears. Do not pack the
