Scheduled Maintenance

SCHEDULED MAINTENANCE

COMPLAINT & ORIGIN

1. Difficult Release Handle Operation

2. PM - Every 450 - 525 hours, (Check fifth wheel release, top plate, and mounting. (Check slide mechanism on sliding fifth wheels.

3. PM - Every 6th PM - Steam clean and inspect fifth wheel, Check and/or adjust lock adjustment. Use Holland Kingpin Lock tester (Part no. TF-TLN-5001)

CONDITION - Fifth wheel difficult to couple and uncouple.

DIAGNOSIS -

A. Check for Center loading (Holland SB #33), look for shiny spots in the recessed surfaces of the fifth wheel.

B. Check for dry lock components and/or the adjustment is too tight.

C. The center of a fifth wheel is recessed to prevent any vertical load. The customer’s trailer upper coupler could be bowed and cause the vertical load to be concentrated in the center of the wheel. This can cause flexing up and down over every bump or ripple in the road leading to top plate cracking. (You may experience excessive fifth wheel cost due to the customer’s trailer condition)

D. A wavy or distorted upper coupler (trailer) will cause galling, premature wear and potential failure. Look for severe wear areas, galling and/or dry spots in either the top plate or the trailer upper coupler.

E. Heavy loading on trailers without adequate upper coupler strength can cause the upper coupler to bow, pulling the kingpin upward when the trailer is resting on the fifth wheel. The release will be difficult due to the upward pull on the fifth wheel locks.
