DRIVE SPROCKET REMOVAL

• 

STEP 1

 – Prevent the sprocket from rotating by inserting the 

scrench or screwdriver through the holes in the sprocket and 
the hole in the saw body.

• 

STEP 2

 - Loosen the Trantorque using  a 7/8" box end 

wrench.

• 

NOTE

 - Slurry will accumulate inside the trantorque adaptor 

while cutting.  This can fill expansion spaces and make it 
difficult to remove.  To faciliate removal, turn the hex nut 
counterclockwise approximately 1/8 turn, and then turn it 
clockwise slightly, so the hexnut is loose.  Then lightly tap 
the end of the ring inside the hex nut several times with 
your box wrench.  (This will loosen the slurry and allow the 
components to slide for removal.)  Continue to turn the hex 
nut counterclockwise to free the sprocket and trantorque. 

DRIVE SPROCKET INSTALLATION

• 

STEP 1

 - Clean the drive shaft and Trantorque surfaces well 

before installation (Isopropyl alcohol is reccommended, to 
remove grease or hydraulic fluid).

Note: Do not lubricate Trantorque or shaft as slippage may 
occur.

• 

STEP 2

 - Slide the Trantorque shaft adaptor onto drive 

shaft until it bottoms on the shaft.  Note: Do not lubricate 
trantorque or shaft as slippage may occur.

• 

STEP 3

 - Slide drive sprocket onto the trantorque until it hits 

the bottom of the shaft.

• 

STEP 4

 - While holding  the sprocket and trantorque as 

close to the frame of hte saw as possible, finger tighten 
trantorque shaft adaptor.

• 

STEP 5

 - Stop the sprocket from roatating by inserting a 

scrench or screwdriver through the holes in the sprocket and 
the hole in the saw body.

• 

STEP 6

 - Tighten the Trantorque shaft adapter with a torque 

wrench and a 7/8" socket to 200 in-lbs (22.6 Nm).  When a 
torque wrench is not available, use a 7/8" box end wrench 
and tighten one-half turn past finger tight.

Note: Do not turn around or reverse the direction of  the 
drive sprocket to extend sprocket tooth life.  Damage to 
chain or drive links may occur.
