(1) wheel axle, (2) U bolt, (3) lower frame 

 

TIP 

 

If  hub  cover  is  damaged or  missing,  contamination  and  dampness  enter  the  hub,  which 
causes significantly faster wear of bearing and hub seals. 

Bearing  life  is  dependent  on  working  conditions  of  trailer,  loading,  speed  of  travel  and 
lubrication conditions. 

 

Preparation procedures 

  Hitch trailer to tractor, braking tractor with parking brake. 

  Park tractor and trailer on hard level ground. 

  Tractor must be placed to drive forward. 

  Place  securing  chocks  under  one  trailer  wheel.  Ensure  that  trailer  shall  not 

move during inspection.
