Place the travel select lever in the (N) NEUTRAL DETENT position, engage the parking brake switch and raise the boom to a horizontal (level) position. 2.
General Maintenance B. Top Boom Chain Tension Adjustment (As required) NOTE: Always perform the ìBoom Chain Tension Checkî on page 150 before adjusting the boom chain tension. 1. Park the vehicle on level ground. Place the travel select lever in the (N) NEUTRAL DETENT position, engage the parking brake switch and raise the boom to a horizontal (level) position. retract the boom completely and turn the vehicle OFF. 2.
General Maintenance 3. Return to the cab, start the engine and cycle the boom all the way out and all the way in several times. 4. Fully extend the boom, then retract it 2" (51 mm) (one inch per section). Turn the vehicle OFF. 5. Measure the sag (1) in the top boom extend chain (2) between the bottom of the chain and the top of the intermediate boom (3) at their closest point (1). Acceptable boom chain sag is between 3.00" (76 mm) and 4.00" (102 mm). If the measurement is still less than 3.
General Maintenance Reposition Extend Chain Clevis NOTE: Before proceeding with the repositioning of the extend chain clevis, check the chain for any chain stretch that might have occurred. Refer to ìElongation Extend Chain Onlyî on page 157. 1. Return to the cab, start the engine and fully retract the boom. With the boom horizontal, extend the boom out approximately 2 ft (610 mm) and shut the vehicle OFF. 2. At the front underside of the outer boom (4), loosen the retract chain adjustment nut (5).
General Maintenance 4. At the front top of the outer boom (1), remove one of the retaining rings (2) from the clevis mounting pin (3). Remove the pin from the mounting plates. Inspect the pin for wear or other damage. Replace the pin if damaged. 5. Move the extend chain clevis (4) to the next hole toward the rear of the mounting plates. Coat the mounting pin with an anti-seize compound and reinsert the pin through the mounting plates and the clevis. Reassemble the retaining ring. 1 7 4 3 2 OU0890 6.
General Maintenance C. Boom Chain Inspection Extend Chains (250 Hour Intervals) Retract Chains (1000 Hour Intervals) 250 OH2710 OU0850 1000 OH2690 OU0870 WARNING: Worn pins, stretched or cracked links or corrosive environments can cause chain failure. A chain failure could result in uncontrolled boom movement, loss of load or vehicle instability and could cause death or serious injury and/or property damage.
General Maintenance The above load cycles and environmental conditions make it impossible to predict chain life. It is therefore necessary to conduct frequent inspections until replacement life can be predicted. The boom chainís normal life expectancy can be expressed as a maximum percent of elongation. This is generally 3%. As the chain flexes back and forth over the sheave, the bearing joints (pins and inside link plates) gradually incur wear due to articulation. Inspection Guidelines 1.
General Maintenance Elongation - Extend Chain Only When the original length (3) of 12.00" (305 mm) per foot of new chain has elongated from wear to a length (4) of 12.36" (313 mm), the chain must be discarded and replaced. It is important to measure the chain in the section that moves over the sheaves because it receives the most frequent articulation. Measuring the chain near its clevis terminals could give an inaccurate reading.
General Maintenance Turning or Protruding Pins Highly loaded chain, operating with inadequate lubrication can generate abnormal frictional forces between pin and link plates. When chain is allowed to operate in this condition, a pin or series of pins, can begin to twist out of a chain, resulting in failure. Examine the pin head rivets to determine if the ìVEEî flats are still in correct alignment (1). Chain with rotated/displaced heads (2) or abnormal pin protrusion (3) should be replaced immediately.
General Maintenance Cracked Plates Inspect the chains very carefully, front and back as well as side to side, for any evidence of cracked plates. If any one crack is discovered, the chain should be replaced in its entirety. it is important, however to determine the cause of the crack before installing a new chain so the condition does not repeat itself. The types of cracks are: ï Fatigue Cracking - Fatigue cracks (5) are a result of repeated cyclic loading beyond the chainís endurance limit.
General Maintenance D. Chain Lubrication Extend Chains (250 Hour Intervals) 250 OH2710 Retract Chains (1000 Hour Intervals or Annually) After inspection and before being returned to service, chains must be lubricated with a quality chain lubricant (ìLUBRIPLATEî Chain & Cable Fluid, ìLPS3î or equivalent). OU0860 1000 OH2690 OU0880 The lubricant must penetrate the chain joint to prevent wear.
General Maintenance E. Wear Pad Inspection (Boom) (50 Hour Intervals) 50 OH2680 OU0820 Visually inspect the boom wear pads between the boom sections at the rear and front of the boom for excessive wear. The average expected life of the wear pads will vary depending upon vehicle use, weight of the loads, operating conditions and the location of the boom pads inside the boom.
General Maintenance The total thickness (1) of a new wear pad (2) is .625" (16 mm). The angled cut (3) will provide a total wear thickness (4) of .25" (6 mm) on load bearing pads or .18" (4,6 mm) on the side non load bearing pads. This will leave approximately .375" (10 mm) of total unused base material. The pads must never be worn past the angled cut indicator because the metal pad insert (5), that holds the pads in place, will begin to wear into the boom pad sliding surfaces.
General Maintenance 19. Transfer Carriage Rollers and Wear Pads Transfer Carriage Rear Wear Pad Check (50 Hour Intervals) NOTE: The attachment should remain attached to the quick attach for these checks. 50 OH2680 OU0830 1. Park the vehicle on level ground. Place the travel select lever in the (N) NEUTRAL DETENT position, engage the parking brake switch and raise the boom to a horizontal (level) position. 2. Leave the transfer carriage completely retracted. 3. Fully extend the boom.
General Maintenance Wear Pad Shimming (As Required) NOTE: The attachment should remain attached to the quick attach for this procedure. 1. Park the vehicle on level ground. Place the travel select lever in the (N) NEUTRAL DETENT position, engage the parking brake switch and raise the boom to a horizontal (level) position. 2. Leave the transfer carriage completely retracted. 3. Fully extend the boom. The attachment must remain slightly off the ground. Turn the vehicle OFF. 4.
General Maintenance 3. This procedure will require the gap check to be made in three separate locations. Transfer carriage all the way retracted, transfer carriage all the way forward and the transfer carriage moved forward about halfway. 4. With the transfer carriage all the way retracted, use a rawhide hammer to tap the rollers (5) against the rails (6). Check the gap (7) between the roller and the existing shims (8) with a feeler gauge. Check both rear rollers and record the gap on each side. 5.
