D: ADJUSTING THE STOPPERS AFTER REPLACING BOGEY. 

If a new rear bogey has been fitted, then the first thing that needs to be done is to line up the rear axel as accurately as possible. Then weld a new pointer unto the new Bogey correctly in line with the one on the chassis. Remember to open both ball valves in the control box early type (see FIG 21) or screw out the flow restrictors a few turns later type (see FIG 25) to allow the rear axel to freely move. 
Then line up front and rear pointers and close both valves, or flow restrictors. 
A new Bogey may not have the stopper blocks in the same position as the originals, therefore the stoppers should be screwed in a few turns. Now turn the tractor unit to 90 degrees to the trailer and park in this position. Screw the stopper out until it is tight against the stopper block (won't screw out any further). 

Repeat the above operation in the opposite direction, and screw the stopper out tight against the stopper block. Then bring front pointers back into line. Screw both stoppers out 1½ turns. Then proceed to adjust as described in section C (Rear bogey stoppers) 

E: REAR RAM ADJUSTMENT 

From mid 2003 the stoppers are replaced by adjustment in the ram itself. The Ram bottoms in the fully closed position. The adjustment is achieved by turning the rod itself, using a 30mm spanner; after slacking the lock nut. 
The steering is adjusted in the same way as with the stoppers section “C” Rear bogey stoppers except that the NS ram is adjusted when the tractor unit is turned to the NS. 
The OS ram is adjusted when the tractor unit is turned to the OS. Always remember to tighten the lock nut thoroughly when adjustment is complete
