CAUTION

Rotabolts with no plastic sleeving should not be used.

(3)

If bolts require tightening, firstly back off the nut before re-tightening commences. This

procedure helps to break the initial stiction which may be greater than the required torque.

Install

(1)

Fit new rotabolts (3) washers (2) and friction grip nuts (1).

(2)

Ensure the bolts are positioned centrally in the holes.

(3)

Tighten nuts in numerical order, as shown in the rotabolt tightening sequence, to a torque

of 500 lb/ft (678 Nm).

(4)

Repeat tightening sequence until the rotabolt control cap locks. Indicating achievement of

the pre-load of 880 lb/ft (1193 Nm).

NOTE

The cap is tight when it will not rotate when gripped as tightly as a pen.
