MOTOR REPLACEMENT 

(T9250/9350/9450HRT)

 

 

Tools required: 

  Philips screwdriver 

  T-handle wrench (14mm) 

 

Ratchet Box Wrench (11mm)

 

 

Procedure:

 

1.  Remove  top  motor  cover 

and bottom motor cover. 

2.  Remove  cables  connecting 

to  the  motor  and  the  lower 
board,  Meanwhile,  remove 
the ground wire   

3.  Using  your  thumb  to  press 
the  surface  of  belt  and  at  the 

same  time  rotate  the  pulley  in  counter-clockwise  till  the  poly  belt  being 
removed. 
4.  Remove the mount bolts on the bottom of motor bracket to take off bad 
motor.   
5. 

Secure the motor mount bolts (not too tight at this time. So the motor can 

be adjusted in horizontal direction). 
6.  Place the drive belt on the transmission pulley, turn the flywheel clockwise 
by using your left hand and place the drive belt on to grooves of the front 
roller pulley. 
Notice! Not allow alignment exists on both pulleys or the poly belt will fall 
down when running. 
7.  Adjust the belt-tension-adjusting screw until the tension is within 80 ~ 
90lbs. 
8.  Tighten the motor mount bolts 
9.  Reconnect cables and the ground wire. 
10. Turn on the power and enter the Engineering Mode to check if the 
extreme speeds are within the correct range. 
11. Try to step on the belt at low speed to check if the belt slips.   
12. Install the front cover and secure the screws.
