 3P8 HF-wire saw and Pentpak - Original instructions

7.1.4

 

Cog belt 

The cog belt that drives the main drive pulley is a Gates Polychain GT Carbon belt. Its length is 720 mm, width 21 mm, 

Gates denomination 720-8M GT2. 

The cog belt will last for at least 100 hours, in most cases well over 150 hours. The lifetime will depend greatly on how 

many times the wire jams in the cut.  

Try to avoid using wires with different sizes of beads. Differently sized beads and sections of wire will cause jamming and 

will shorten the life of the cog belt. 

The cog belt can be replaced in about 10 minutes, after some practice. Please see the next pages for instructions how to 

replace the belt. 

Disassembly 

1.

Remove the center bolt holding the pulley. 14 mm allen key.

2.

3.

Remove all M6 bolts holding belt cover to back cover. 5 mm allen key.

4.

Remove the belt tensioning bolt. 6 mm allen key.

5.

6.

Lift main drive pulley and slide it off the pulley shaft while holding back the cog belt

Assembly 

1.

Put a new belt on the small cog wheel.

2.

Slide the main drive pulley on to the pulley shaft while at the same lifting the pulley and putting

the belt over the big cog wheel pulley.

3.

Push the pulley inwards while at the same time turning it to make the belt line up.

4.

Tighten the pulley shaft bolts slightly.

5.

Tighten the belt tensioning bolt firmly.

6.

Tighten the pulley shaft bolts firmly. (60 Nm)
