Pronar PT610 

5.9 

  Loosen wheel nuts according to sequence shown in figure (5.4). 

  Place lifting jack and lift trailer. 

  Dismount wheel. 

Wheel mounting 

  Clean axle pins and nuts of contamination. 

  Do not grease thread of nuts and pins. 

  Check condition of pins and nuts, if necessary replace them. 

  Place wheel on hub, tighten nuts so that wheel rim tightly fits the hub. 

  Lower  the  trailer,  tighten  nuts  according  to  recommended  torque  and  given 

sequence. 

 

TIP 

 

Wheel nuts should be tightened using the torque of 450 Nm - M22x1.5 nuts. 

 

Tightening nuts 

Nuts should be tightened gradually diagonally, (in several stages, until obtaining the required 

tightening torque) using a torque spanner. If a torque spanner is not available, one may use 

an ordinary spanner. The arm of the spanner (L), figure (5.4), should be selected according 

to the weight of the person (F) tightening the nut. Remember that this method of tightening is 

not as accurate as the use of a torque spanner.
