Telsmith Vibrating Aggregate Screen 5 x 16 Triple Deck

Consult the Telsmith Engineering Department before proceeding with any change in counterweight balance shims.

Remove the two hex head capscrews holding the counterweight shim stack to the face of the counterweight.

Slide the shims out one at a time off the counterweight hub and lower to the floor.

If additional shims are required, slide them on the counterweight hub.

Fasten the shims in position with the two hex head capscrews ensuring proper engagement with the counterweight hub.

Ensure that the shims do not protrude past the end of the counterweight hub.

Remove the drain plug from both manifolds and drain oil into a container large enough to contain approximately 8 gallons of oil.

Elevate one side of the screen to facilitate drainage, if necessary.

Refill system with 7 gallons (26 L) of specified gear oil for your operating conditions.

Re-check oil level in both manifold sight windows and refill to full line if necessary.

Check wire weave for breaks, tears or separation of the wire.

Replace wire that exhibits any damage.

Observe operating screen for any panels with 'dead spots' where material is puddling.

Replace wire panels that no longer maintain tension over the complete surface area.

Screen Tension and Buffer Check

Check that screen is tight against all buffer and crown bars.

Check if rubber is missing, torn or worn through to the metal on crown bars.

Check vibrator oil for impurities (oil sample)

Check nuts and bolts for tightness or missing fasteners

Check decks for heavily worn hardware or worn cross members

Check that vibrating unit drive sheave is free of debris and tight on shaft bushing

Check that electric drive motor output sheave is tight on shaft

Structural and Frame Inspection

Inspect friction pucks. Replace if surface is worn below usable dimension

Check live frame for cracks or broken welds

Lockout/Tagout power to screen as detailed in Chapter 1.

Remove the drive belt(s) from the electric motor(s) as detailed in Chapter 3.

Remove the friction dampening puck from each base assembly by removing the access cover and pulling the spring and friction puck out of the base assembly.

Lift the screen several inches off the screen springs and base frame using a lift hoist and spreader frame of sufficient capacity for your model screen.

Block the screen up on blocking of sufficient capacity to support the screen.

Is the spring free height less than 14.5 in. (36.3 cm)?
