Pusat Khidmat Pelanggan Kenworth menawarkan banyak nasihat mengenai roda kelima jaga. Pertama sekali, fikirkan keselamatan semasa anda memeriksa roda kelima anda. Terdapat beberapa perkara yang boleh dilakukan oleh pemandu:
•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.
Sebelum anda memulakan pemeriksaan anda, pastikan keseluruhan sistem roda kelima dibersihkan dengan wap dengan teliti. Bersihkan plat atas, kurungan, plat slaid, sudut pelekap dan pengikat. Seterusnya, supaya anda boleh melihat dengan baik pada roda kelima, gunakan lampu bermasalah atau lampu suluh untuk pemeriksaan visual anda. Rancang untuk mengambil masa 10 atau 15 minit untuk projek ini.
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.
Jika plat bergerak, rahang mungkin haus. Jika rahang sudah haus, roda kelima mungkin merupakan roda yang boleh dibina semula dan bukannya diganti, jadi tanya pembekal atau peniaga anda tentang pilihan itu.
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.
