Revision A

5.3.3 PF Timing Belt Tension Adjustment

This adjustment is necessary for service operations that require you to remove/loosen the PF Motor or PF Belt. When replacing or re-installing the PF Belt, you need to confirm the tension of the PF Belt.

Adjusting tools: Tension Gauge #F770

Standard:	2,200g ± 10%
	(Tension in the PF motor mounting plate moving direction.)

NOTE: For disassembly and assembly procedure, refer to “PF Motor (p.185)”.

Loosen the screws (x4) fixed to the PF motor mounting board and set the tension gauge to the hole on the board and pull to the movable direction.
