Adjustments !1 o !2 q i u r !0 s Adjusting the tension of X-timing belt A326 X-timing belt A326 e is looped around X-timing pulley A311 (A326) q and X-timing pulley B326 w. The tension of X-timing belt A326 e should have 1 mm deflection when it is pressed in the middle of X-timing pulley A311 (A326) q and X-timing pulley B326 w with a load of 4.9N (0.5 kgf) in the direction of the arrow. Turn the bolts r clockwise to move X-pulley bracket L t until the appropriate tension is given, and secure X-pulley bracket L t to the bed using the screws y. Note: The bolts r for adjusting the timing belt tension are in front of and behind X-pulley bracket L t. Adjust the bolts r equally so that X-pulley bracket L t does not lean to one side. s Adjusting the tension of X-timing belt B326 X-timing belt B326 o is looped around timing pulley A u and timing pulley B i. The tension of X-timing belt B326 o should have 3 mm deflection when it is pressed in the middle of timing pulley A u and timing pulley B i with a load of 9.8N (1 kgf) in the direction of the arrow.
