Hi Karl

 

If you have broken a fan you cannot replace a single fan side.

 

The fans have to be replaced as a pair because the rotor needs to be balanced and it cannot be guaranteed that the rplacement is the same weight as the original , hence it is highly recommended to replace the pair.

 

It is a reletivly easy job to do

Slacken and remove the 3 drive belts

Remove taperlock and drive pulley from shaft

REmove the rear bearing housing

Remove the hopper and feed tray

Take off both motor and slide from the drives

Remove the Roller box assembly

Remove front plate complete with rotor assembly

When you replace the fans use the same nuts and bolts in the same holes as there is balancing washers under each bolt and these to be put back in the same place.

Clean rotor face and remove any debris

Torque bolts up to 30 then 40 & then 50 lbs ft in sequence

 

refit the front plate then refit all parts in reverse order

 

If you are not confident to perform the work we would recommend that you seek assistance from a TW dealer.

 

hope that this helps you

 

regards
