Top Roller Replacement
On newer models, (from 2000 and up or so) the side plates have large enough holes to allow
for top rollers to be removed from machines without having to take off a side plate. For older
machines without this feature, the steps above in the section titled
“ Feed Roller Replacement ”
will have to be followed. For newer models:
• Disconnect power and air. Allow hot surfaces to cool to prevent contact with hot
surfaces.
• Start on the right or left side of the machine (it doesn’t matter which side) and loosen
the bolts clamping the AM1 Spring Arm to the lift shaft (AM4-9 or AM7-9). Loosen the
spring arm bolts on both sides and remove Spring Blocks (CC-3 or HC-3) to release
spring pressure on the rollers.
• With the Spring Arm bolts loosened on one side, work the spring arm until it comes off
the machine. Gently prying may be needed.
• With the Spring Arm removed, the top roller can be pulled horizontally out the side of
the machine.
Top rollers can be resurfaced many times. To have your top roller resurfaced, contact
TRC Industries.
• The new or resurfaced top roller can be put inserted back into the machine through the
side plate hole. Make sure the roller shaft engages the bearing in the Spring Arm
opposite the side plate hole the roller was removed from.
• Replace the Spring Arm, making sure to engage the shaft in the bearing correctly.
• Replace the Spring Block by pressing the spring (AM-2) onto the Spring arm stud with
the Spring block stud engaging the opposite side of the spring. With the spring aligned,
press the Spring Block down until the bolt hole in the Spring block is aligned with the bolt
hole in the Side Plate. This may take two hands and some patience.
• With the Spring (AM-2) and Spring block in place asserting force on the Spring Arm,
check the rollers to make sure they are making good contact. It may be necessary to
add pressure to the top roller to make good contact. Tighten the bolt clamping the
Spring Arm to the Lift Shaft.
Spring Tension Adjustment
Spring tension adjustment is required periodically. As different materials are used, and as
springs wear out adjustment will be needed. Too much spring tension can lead to premature
roller wear. Too little pressure will lead to inaccurate or inconsistent material length or material
slippage.
• Loosen jam nut with a wrench.
