Alliance Laundry Systems CHM1772C manual Flat-Pulley Alignment, Distance from Edge

c.For flat-pulley drive systems, verify allowable distance of belt from edge of pulley. Refer to Table 1 below.

	Flat-Pulley Alignment
Model			Allowable
			Distance from Edge
20			.09 in. (2 mm)
30			.09 in. (2 mm)
40			.09 in. (2 mm)
60			.38 in. (10 mm)
		Table 1

d.For F and variable-speed models only, verify that V-belts are properly tensioned by applying a set force to the belts and measuring the deflection to determine the belt tension. Refer to Table 2 for the acceptable belt’s tension ranges. Belt tension measurements should be taken as close to the center of the belt span as possible. Refer to Figure 8.

2.For 80 and 125 pound capacity models only, lubricate bearings and seals each month OR after every 200 hours of operation.

a.Use a premium-grade lithium-based #2 grease. Never mix two types of grease, such as petroleum and silicone.

b.Pump the grease gun slowly, permitting only the following number of strokes:

•Bearing grease fitting, 2 strokes

•Seal grease fitting, 2 stroke

NOTE: Do not pump the grease gun until grease comes out of the bearing housing. This can result in overlubrication, causing damage to bearings and seals.

3.Remove back panel and check overflow hose and drain hose for leaks.

4.Unlock and remove the top cover and check the supply dispenser hoses and hose connections.

5.Clean inlet hose filter screens:

a.Turn water off and allow valve to cool, if necessary.

b.Unscrew inlet hose and remove filter screen.

c.Clean with soapy water and reinstall. Replace if worn or damaged.

6.Tighten motor mounting bolt locknuts and bearing bolt locknuts. Check to see that the pin is in place.
