7. Apply Anti‑Galling Lubricant to the Shaft Head Bolt
and start to thread it into the end of the Shaft with the
3/8" Allen Wrench. Align the key up with the Keyway
and finish bolting the Small Shaft Head into place,
using a torque wrench to install the Shaft Head Bolt
to 95 ft.‑lbs. Apply Anti‑Galling Lubricant to both Set
Screws and thread them into the Shaft using the 1/8"
Allen Wrench. The Set Screws lock the Shaft Head
Bolt in place, preventing it from loosening during the
cutting operations.
6. Thread the Brake Tube down the Thrust Tube by
rotating it in a clockwise direction, as viewed from the
back of the Machine
(see fig. 14)
. Do this until the
Shaft extends out of the Adapter Bell. The distance
will vary depending on the type and size of Adapter
Bell being used.
8. The Jam Nut facilitates easy removal the Shell Cut‑
ters. Thread the Jam Nut onto the Shaft. Run it to the
end of the Threads, and then back off one complete
revolution. With a 3/16" Allen Wrench, tighten Jam
Nut Halves so that the gap between them is even
(see fig. 16)
. Secure the Jam Nut halves by torquing
the Jam Nut Bolts to approximately 50 in‑lbs.
9.
Take the TM Shaft Nose (or TM PVC Pilot) and exam‑
ine the retention ball system. It should require firm-
to‑hard pressure to depress the Ball. The Ball should
snap back into place smoothly. If the Ball is sticking,
disassemble, and clean the Hole, Ball and Spring.
Reassemble, and re‑examine to ensure the Ball is
functioning properly.
Check to see that the Spade Bit in the TM Shaft Nose is
sharp and that it is held securely in the slot. If the Spade
Bit is chipped or damaged, it should be replaced. For
PVC Pilots, check that the teeth are sharp. If the teeth
are chipped or damaged, it should be replaced.
