Belt Over Chain Conveyor Maintenance and Adjustment—As Required (If Equipped)

# 4 Conveyor Chain Maintenance

• CAUTION: Do not remove material while conveyor or spinner is running.

  IMPORTANT: Conveyor will move away from bottom panel if material accumulates under conveyor or on sprockets. The more material that accumulates, the closer the chain will come to the chain shields. If the conveyor should catch chain shield, permanent damage could happen to conveyor, chain shields or unit.

  Hose down unit and remove any material buildup on sprockets and under chain.
• Lubricate conveyor chain daily.
  1. Allow unit to dry after washing.
  2. Shut down spinners and run conveyor slowly. (See initial Start-up procedure in Operating System section in this manual.)
  3. Use mixture of 75% fuel oil and 25% SAE 10 oil in a pressurized hand spray gun.
  4. Spray oil mixture between links of chain through openings provided at rear end of sill or from front outside body when clearance is adequate.
• If a chain oiler is used.
  1. Fill oiler reservoir daily with a mixture of 75% fuel oil and 25% SAE 10 oil.
  2. Before each filling of unit with material to be spread, open petcock and run conveyor until full length of chain has been oiled, then shut petcock.

Chain Maintenance.

Proper belt tension is also a factor in chain and sprocket life.

1. NOTE: Second product bin conveyor contacts bottom of sill only at center when properly tensioned.

   A - Rear Sill Edge

   B - Conveyor Chain

   C - Contact Point

   D - Dimension

   Measure from rear of sill (A) to where conveyor chain (B) contacts with bottom of sill (C).

2. Verify that measurements on both sides of conveyor are equal and within specified range.

   Item	Measurement	Specification
   Conveyor Chain Tension	Distance	91-102 cm. 36-40 in.

3. Adjust at front idler pulley if necessary.

   IMPORTANT: Conveyor chains that are too tight will tend to stretch, causing excess sprocket wear and eventually breakage.

   Excess slack presents the possibility of chain catching on subframe parts.

   Bent or distorted chain bars will cause damage as well. Straighten or replace bent or distorted chain bars immediately.

#4 Conveyor Belt Maintenance

The standard belt for the #4 conveyor has a nylon fabric that is impervious to moisture, weathering or normal action except oil.

1. Inspect belt fastener occasionally for wear or “raveling” of belt grip area.

2. IMPORTANT:

   
   N97840-UN-10APR12

   A - Splice Pin End

   B - Lacing Edge

   Pin must not rotate. If pin ends (A) are not bent down and tight against lacing (B), the ends may cut into the chain shield or belt wipers.

   Verify that belt connecting pin is positioned correctly.
