Ang Kenworth Customer Service Center nagtanyag daghang tambag bahin sa ikalima nga ligid pag-atiman. Una ug labaw sa tanan, hunahunaa ang kaluwasan kung imong susihon ang imong ikalima nga ligid. Adunay daghang mga butang nga mahimo sa usa ka drayber:
•Keep the fifth wheel lubricated.
•Make sure that it is still connecting properly to the trailer.
•Verify that a sliding fifth wheel is locking properly.
•All this can and should be done without touching the fifth wheel yourself.
Sa dili ka pa magsugod sa imong pag-inspeksyon, limpyohan pag-ayo ang tibuok fifth wheel system. Limpyohi ang ibabaw nga plato, bracket, slide plate, mounting angles, ug fasteners. Sunod, aron matan-aw nimo pag-ayo ang ikalimang ligid, gamita ang usa ka problema nga suga o flashlight alang sa imong biswal nga pagsusi. Pagplano og 10 o 15 ka minuto alang niini nga proyekto.
Test those jaws. This is the safest way to examine your fifth wheel’s jaws and make sure they aren’t worn out…it’s a two-person test, so ask someone to help you out for a moment.
•Latch the fifth wheel onto the trailer as usual.
•Set the trailer brakes.
•Have your assistant stand where he or she can see the fifth wheel.
•Move the chassis back and forth slightly.
•Have your assistant watch to see if the plate moves relative to the trailer.
Kung ang plato molihok, ang mga apapangig lagmit gisul-ob. Kung ang mga apapangig gisul-ob, ang ikalima nga ligid mahimong usa nga mahimong matukod pag-usab kaysa pulihan, busa pangutana sa imong supplier o dealer bahin sa kana nga kapilian.
It is possible to have fifth wheels adjusted, but it’s not typically necessary. Talking with Jost, Kenworth learned that this is not something that usually needs to be done with their products, and in fact, frequent adjustments can cause premature wearing of the locking mechanism. Jost states it has many fifth wheels in service with over 400,000 miles on them that have not needed adjustment.
Fontaine said that if it’s needed, its fifth wheels are easy to adjust—they can even be adjusted while the trailer is coupled to the fifth wheel if the situation calls for it.
