Mitek Roller Press Finish Roller

CAUTION: Never mix synthetic lubricants with mineral lubricants!

CAUTION: Do not overgrease bearings. Injection of excess grease under pressure into sealed bearings may rupture seals.

Proper amounts of motor oil and grease maintained

Frequency of lubrication application

Lubricant free from oxidation and contamination

Lubrication guidelines are given in this chapter for each part or system that requires lubrication (refer to Table 6-3 on page 30.) The information is also in the Maintenance Checklist appendix.

Movement of grease through bearings checked visually

Old grease forced out with shot of new grease

NOTICE: Adjusting the air gap improperly may damage the motor. Do not attempt to make this adjustment unless the measured gap is outside the recommended allowance.

If the brake monitor continually trips and other causes have been ruled out, the air gap in the brake motor may need to be adjusted. The recommended air gap allowance is between .016 in. and .043 in. To check the current air gap and to adjust it, refer to Figure 6-1 and the following procedure.

1. Unscrew the manual brake handle extending from the side of the brake motor, if there is one.

2. Using a feeler gauge, measure the gap between the armature disk and brake housing, shown in Figure 6-1. Measure completely around the brake and record any variations in the gap measurement.

3. If the measurement is outside the allowance recommended at any point around the circumference of the brake, adjust the brake disk air gap using the following steps:

c) Pry the fan off of the motor shaft.

d) Adjust the setting bolt as needed to reach the recommended gap. A 1/4 or 1/2 turn is usually sufficient for adjusting purposes. See Figure 6-2.

1. Check the #100 drive chain tension. Drive chain play should be less than 1/2 inch (1/4-inch movement to both sides of center).

2. Check the drive sprocket alignment; the sprockets should be in the same plane. If they are not, see Aligning/Adjusting the Sprocket.

3. If gearbox chain tension is required:

a) Loosen the reducer/gearbox mounting plate bolts (4) and the motor mounting plate bolts (4).

b) Tighten the adjustment bolts (jack screws) on the reducer mounting plate to slide the entire drive assembly outwards until the drive chain play is 1/2 inch (1/4 movement to both sides of center). It is critical to keep the drive centerline parallel with the roller centerline.

c) Tighten the reducer/gearbox and motor mounting plate bolts.;

Proper amounts of motor oil and grease must be maintained at all times. The type of lubrication used, frequency of application, oxidation, and contamination of the lubricant affect service life and parts efficiency of gears and bearings. Improved performance will be obtained by following the guidelines in this manual.

Lubrication guidelines are given in this chapter for each part or system that requires lubrication (refer to Table 6-3 on page 30.) The information is also in the Maintenance Checklist appendix.

CAUTION: Never mix synthetic lubricants with mineral lubricants!

Reducer/gearbox - Drain fluid and refill after first 150 hrs of service and every six (6) months thereafter.

Suggested times: spring and fall-time to change seasonal oil viscosity (light for winters, heavy for summer).

CAUTION: Do not overgrease bearings. Injection of excess grease under pressure into sealed bearings may rupture seals.

Movement of grease through bearings can be checked visually by the appearance of grease at the ends of the bearings.

Old grease should be forced out with shot of new grease. When greasing bearing, wipe the fittings clean.
