1. For pulling trailers with standard SAE kingpins which are in good condition and securely mounted or locked in

position in the trailer.

2. To transport loads that are within the maximum fifth wheel rated capacities: 55,000 lbs. Maximum Vertical Load

150,000 lbs. Maximum Drawbar Pull.

3. In on-road applications.

of off-road refers to terrain on which a tractor-trailer operates which is unpaved and rough, or ungraded. Any terrain not considered part of the public highway system falls under this heading.

4. As recommended in SAF-HOLLAND

literature available on the Internet at www.safholland.us.

: SAF-HOLLAND definition

Failure to couple with a

proper kingpin may result in improper coupling, allowing tractor and trailer separation, which if not avoided, could result in death or serious injury.

2. Tow-away operations which

damage or interfere with the proper operation of the fifth

wheel.

3. The attachment of lifting devices.

4. The transport of loads in excess

of rated capacity.

5. In off-road applications.

6. Applications other than

recommended in SAF-HOLLAND literature available on the

Internet at www.safholland.us.

1. Use with non-SAE kingpins, such as kingpins which are bent, improper size or dimensions, not secured to maintain SAE configuration, or which are installed in warped trailer bolster plates, or upper coupler and fifth wheel lube plates that do not maintain the SAE kingpin dimensions. Refer to SAF-HOLLAND Service Bulletin XL-SB004-01(available on the Internet at www.safholland.us) for more information on fifth wheel lube

plates.

1. Prior to coupling you must inspect the fifth wheel and

mounting.

• Confirm that lube plates are in

place and firmly fastened.

• Tighten loose fasteners.

• Replace missing fasteners.

• Repair/replace missing,

cracked or otherwise damaged components.

• If you have a sliding fifth

wheel, make sure both plungers are fully engaged.

• Inspect air line connections.

FWAL fifth wheels are equipped with NoLube plate inserts that eliminate the need to lubricate the fifth wheel-

to-trailer contact surfaces.

Thoroughly clean the locking mechanism every 6 months or

60,000 miles.

The FWAL is equipped with NoLube lock coating technology. The lock components are protected with a lowfriction coating which provides long wear life and corrosion protection, eliminating the need for lubrication. The locking mechanism of a new FWAL fifth wheel assembly has a thin layer of grease applied by SAFHOLLAND to aid the components for an initial “break-in” period. Grease will not adversely affect an FWAL

NoLube fifth wheel.

Fifth wheel adjustment should be checked at a minimum of every 60,000 miles or if excessive movement between kingpin and fifth wheel is noticed when driving the

To obtain proper fifth wheel adjustment SAF-HOLLAND recommends use of Holland lock tester Part No. TF-TLN-5001, available from your local Holland

distributor.

3. To lock fifth wheel, rotate handle on

lock tester clockwise until the locks close around the kingpin (

).

4. Slide the lock tester forward and

backward in the closed lock to check for play between lock and kingpin. Ensure that the tool remains flat with full contact on the fifth wheel top plate. Use pin gage to measure free play. If free play exceeds 0.080”,

adjust lock mechanism (

5. To adjust lock, unscrew the low head

socket cap screw until the head clears the adjusting pin and rotate adjusting pin counter-clockwise until the next notch lines up with the low head socket cap screw. Re-tighten low head socket cap screw. Adjust

only one notch at a time (

6. Verify the proper adjustment by locking and unlocking fifth wheel several times with lock tester (“Step 3 previous page). Check that fifth wheel is

properly locked (

7. Rotate lock tester from side-to-side to

).

ensure that lock is not overtightened. Lock should not grip kingpin and the

tool should rotate freely (
