Coupler Assembly Replacement - Graco PrecisionSwirl 243402 Instructions-Parts List Manual

Coupler Assembly Replacement

There are three ball bearing assemblies in the Preci-
sionSwirl orbital dispenser - two in the motor and one in
the motor coupling for tube support.
Only the orbiter coupling and its bearing may be
removed and replaced. If the motor bearings need to be
replaced, the entire motor requires replacement. The
tube support coupler (24) should not be removed unless
a new replacement coupler assembly is available.
Replace the complete coupler assembly, do not attempt
to replace the bearing only.
The repair technician must use the proper tools to
avoid damaging the bearings. Tools are provided in
bearing repair tool kit 241569.
Coupler Assembly Removal
Before removing the coupler assembly (24), you
must remove the bearing from the coupler.
1. Place motor assembly onto the coupling support
tool. Refer to F . 2.

2. Use the push rod tool to press the bearing out of the
coupler. The push rod tool is the 4-in. piece of bar
stock included in Kit 241569. Discard the bearing.

bearing.
