	FIG 45 HOPPER SLIDE PLATES

Location:

The slide plates are located on the solenoid mount- ing plate immediately beneath the hopper openings.

The slide plates must always remain flat for proper operation.

Test Procedure:

With the solenoid mounting plate attached to the hopper, push the solenoid plunger into the coil. The slide plate must move freely in the assembly and snap closed when the plunger is released. Repeat for the other slide plate.

If the slide plates move as described, they are operating correctly.

If the slide plates do not move as described, the problem may be in any one or more of the linkage pieces, springs, slide plates, and/or the solenoid mounting plate. Disassemble the solenoid mounting plate assembly and inspect all components for free movement.

Replace if excessively worn or damaged.

A.Solenoid Coil

B.Slide Gate

C.Slide Gate Support

D.Collector

E.Collector Seal

F.Solenoid Mounting Plate

Removal and Replacement:

1.Remove the hopper from the grinder.

2.Remove six slotted head screws holding the sole- noid mounting panel to the hopper.

3.The slide plate with attached linkage can be lifted off the pivot pin and removed with the solenoid plunger.

4.Refer to the illustration above when reassembling the components.

5.Inspect the slide plates after reassembly. They must move freely.
