I have a DML36SH lathe and I want to change the belt, are any specialist tools required?�Is it a matter of just undoing the allen key on the head stock and pulling the spindle through from the other end, or will I have to give it a tap with a hammer? As I imagine it will be a tight fit.

No specialist tools are required to carry out the procedure you will need:
>Mallet
>Solid brass rod 1/2" dia. (drift)
>Set of metric allen keys

The bearings and spindle are a pressure fit in the casting, and to remove them you are required to drive them out from the back through the front of the headstock using a drift.
Please remember to remove the socket head cap screw and washer on the back end of the shaft, take out�the first grub screw in the spindle pulley and loosen the�lower grub screw, before you proceed. The pulley should now float freely on�the shaft. The spindle can now be removed through the front of the headstock.�Using the brass rod and mallet drive the spindle from the back end of the headstock towards the front, once the spindle has been released from the back bearing this allows the drive belt to be changed.
After the belt has been changed reverse the�procedure to re-assemble the headstock, but ensure that�when driving the spindle back in from the front�, the thread�protector is fitted. As the spindle is being driven in, it must�rotated by�hand at each strike of the mallet, this prevents the spindle and bearing being damaged and�'flatted'. As�the spindle�seats in the back bearing you will hear a tone change in the casting.
If in doubt please refer to your instruction manual which details the belt change procedure.
