B.Assembly of Rotor Shaft.

CAUTION	IF THE BEARING ADAPTERS ARE NOT PRECISELY TIMED 180 DEGREES APART
	IN EACH ROTOR AND ALIGNED BETWEEN ROTORS, SERIOUS DAMAGE WILL
	RESULT.

1.Rotate the adapters in each rotor so the timing marks (see Figure 10) are phased 180 degrees apart with hex

	bores aligned.	TIMING MARK FOR PHASING
2.	To assist with aligning timing marks between rotors, use	TIMING MARK FOR PHASING

3.Install the required components in the sequence shown in Figure 6, double-checking the timing mark locations and spacer lengths (see following table) as each rotor is installed.

CAUTION

CLEAN THE ROTOR SHAFT THOROUGHLY REMOVING ANY BURRS THAT WOULD KEEP THE ROTOR ASSEMBLIES FROM SLIDING ON FREELY. IF A BEARING ADAPTER JAMS, THE INTERNAL BEARING SEAL COULD BE FORCED OUT AND IT IS NOT REPLACEABLE.

NOTE: THE SPACERS MUST BE FULLY SEATED IN EACH ADAPTER COUNTER BORE BEFORE TIGHTENING. DO NOT FORGET TO PLACE THE BEARING STAMPINGS ON EACH OF THE SHAFT BEARINGS DURING REASSEMBLY. ALSO, THE 3/8" CARRIAGE BOLTS SHOULD BE PLACED IN THE BEARING STAMPINGS ON THE DRIVE END OF THE SHAFT BEFORE THE SHEAVE IS REPLACED.

4.Replace the 1-1/8" hex jam nut and rotate each rotor occasionally as the nut is being torqued to 350 ft- lbs. If any rotor locks up, the bearing adapters in the rotor are probably not phased 180 degrees apart.

D. Installation of Main Shaft Assembly

Reinstall the rotor shaft into main frame by reversing the shaft removal steps outlined in I-A. Refer to Figure 6 for correct location of bearing stampings, bolts, etc. Tighten the 3/8 flange lock nuts at each bearing to 35 ft-lbs.

CAUTION

THE TWO STAMPINGS ON EACH BEARING ARE IN CONTACT WITH EACH OTHER IN THE ASSEMBLY. NEVER SEPARATE THE BEARING STAMPINGS TO STRADDLE A FRAME MEMBER.
