Installing The Magazine Brake Assembly

The magazine brake is very useful when the pneumatic pressure to the pusher arm is turned off. Without the pusher brake assembly, when the pneumatic pressure is cut, the pusher arm is held against the case blanks entirely through the frictional resistance of the carriage frame. The purpose of the magazine brake is to prevent the magazine pusher arm from being pushed back towards the infeed end of the magazine in these situations. When the pneumatic pressure is cut, the brake enables the pusher arm to maintain pressure against the stacked cases. The brake, which is equipped with a release handle, affords quick brake release for magazine reloading or any other circumstance requiring the release of pressure on the case blanks.

To accommodate your machine’s handing, we have a right-handed and a left-handed assembly. The Right-Handed Brake Assembly’s part number 63-3378; the Left-Handed Brake Assembly’s part number is 63-3377. For your reference, we have included both assembly drawings in this document. These drawings show mounting configurations for the part numbers for each assembly. Please contact the Parts Department at 604-930-9300 for current pricing.

1. New machines feature a guide angle that helps to square the unformed stacked cases in the magazine instead of the guide bar system used previously. If your machine features a guide angle, it is advantageous, although not strictly required, to remove the guide angle prior to installing the magazine brake assembly. To do so, use two nyloc 9/16” wrenches to remove the bolts that secure the guide angle to the magazine guide assembly. Depending on the machine, there may be 2 or 3 bolts that require removal.
2. Before installing the brake assembly, ensure that the upper track channel is free of lubricants, dirt, and debris. Failure to do so may result in improper function of the brake assembly.
3. Using a ½” wrench, remove the four 5/16” hexhead capscrews that secure the pusher arm mounting bracket to the magazine assembly carriage frame. The pusher arm assembly can now be removed.
4. Place the assembled brake assembly directly onto the magazine assembly carriage frame. Three throughholes have been incorporated into the design of the brake mounting plate. Regardless of whether the machine is left- or right-handed, the central hole corresponds to the shoulder bolt located in the center of the magazine assembly carriage frame. Likewise, the upper and lower through-holes correspond to the positions of the pemnuts on the magazine assembly carriage frame which are closest to the infeed end of the magazine. The four bolt holes oriented in a rectangle around the shoulder bolt through-hole correspond to the four 5/16” hexhead capscrews that secure the magazine pusher arm mounting bracket to the magazine assembly carriage frame. Mount the magazine brake assembly such that the through-holes and bolt holes align with the shoulder bolt, pemnuts, and capscrew bolt holes.
5. Then place the pusher arm assembly over the magazine brake assembly so that the bolt holes on both components align. The brake assembly should now be mounted between the carriage frame and the pusher arm assembly.
6. Most Wexxar machines are constructed with a 1” thick pusher arm mounting bracket, although some machines instead feature a 1/8” sheet metal pusher arm mounting bracket. If your machine features a 1” bracket, refer to step 7 below. Otherwise, skip to step 8.
7. Use a ½” wrench to insert the four 2 ½” hexhead capscrews that were sent with the magazine brake assembly into the four capscrew mounting holes. Skip to step 9.
8. Use a ½” wrench to insert the four 1 3/4” hexhead capscrews that were sent with the magazine brake assembly into the four capscrew mounting holes.
9. The pusher arm assembly will now be secured to both the brake assembly and the magazine assembly carriage frame.
10. Replace the guide angle, if applicable.

In order to keep the brake in optimal condition, it is recommended that you clean the upper track channel and wipe down the surface of the brake with a dry cloth at monthly intervals.
