SERIES BST1xx-6 TRANSFER ARM REPAIR AND REPLACEMENT INSTRUCTIONS

PERIODIC LUBRICATIONSeries BST Transfer Arms linear bearing systems are factory lubricated with FDA approved food grade lube and may not need further lubrication for the life of the unit depending on the duty cycle of the machine. Lubrication of the linear bearing system every six months however will provide extended life. The BST Transfer Arm carriage is equipped with a grease zerk for customer lubrication maintenance (see page 4 for carriage lubrication instructions).

NOTES:1. PHD recommends using Loctite® 246 thread locker on threaded fasteners.2. PHD recommends using Loctite® R/C 680 where specified (Race Locker).3. PHD recommends using food grade lubrication on metal-to-metal contact points.

HEAD REPLACEMENT1. Remove return extension springs (10).2. Remove screw (25) from rail & carriage assembly (2) using 4mm hex wrench.3. Remove gripper head (24) from rail & carriage assembly (2).4. Place new gripper head assembly (24) onto rail & carriage assembly (2).4. Apply thread locker to screw (25), using 4mm hex wrench torque to 140 in-lb [15.8 Nm].5. Apply small amount of lubricant on return extension spring hooks and re-attach springs (10).

NOTE: PHD highly recommends the application of lubrication applied to the inside of the spring hooks and the post grooves for maximum life.

Forces are calculated based on dimension from the center of the shafts to the center of the preform/bottle as shown in Figure 1. If tooling is longer or shorter than that shown, grip force will vary from the list given.

Consult PHD for grip force other than listed.

NOTE: Pull out forces are related to grip forces but will vary depending on finger tooling design. PHD springs will allow process refinement for both bottle and preform transfer.
