Chapter 9 Maintenance & Inspection
PAGE 9-4
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;
over-greasing could damage the tool and cause it to stall. Recommended grease: Eastlube 191 or
equivalent. (Eastern Oil Company Pontiac, MI. 248-333-1333)
6. REASSEMBLE TRANSMISSION. If available, 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 re-assembly, then disassemble the transmission again to isolate and
correct the cause.
7. RE-ASSEMBLE TOOL. Connect the transmission to the motor with (3) screws. If needed, rotate the
output shaft to align the transmission planetary gears with the motor output (square) shaft. Connect the
transducer to the transmission with (3) 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. Re-connect transducer cable and re-assemble case and cover
plates.
Note: Snap ring installation must be last step in re-assembly
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. Install the tool into the application and verify there is no binding.
