8.2.4 Transmission Disassembly and Inspection
{ 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.
{ To prolong the life of the transmission assembly, the components must be inspected and
lubricated 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
transmission housing with excessive grease; overgreasing could damage the tool.
Recommended grease: Sunoco Sunaplex 992 EP or equivalent.
6. REASSEMBLE TRANSMISSION. Refer to the appropriate transmission assembly
drawing while reassembling the transmission. If needed, rotate the gears to aid in the
assembly process. If the transmission does not rotate freely after reassembly, then
disassemble the transmission again to isolate and correct the cause.
7. REASSEMBLE TOOL. Connect the transmission to the motor with four (4) screws. If
needed, rotate the output shaft to align the transmission planetary gears with the motor
output splined shaft. Connect the transducer to the transmission with four (4) screws.
Install the snap ring onto the output shaft to hold the outer bearing in place. If the
transmission does not rotate freely after reassembling the tool, then disassemble the tool
again to isolate and correct the cause.
NOTE: Snap ring installation must be the last step in reassembly.
8. INSPECT SPINDLE ASSEMBLY. Prior to installing the tool into an application, inspect
the spring loaded spindle assembly that will connect to the tool. The assembly should
compress evenly, without binding. Rotate the assembly in the spindle housing and verify
there is no binding. Visually inspect the entire assembly for signs of wear or fatigue.
Replace parts as required, and reassemble. Lubricate the inner bearings of the housing
as required, and reinspect the final assembly. Install the tool into the application and verify
there is no binding.
