tensioner
1.

Put an M8 x 90 bolt (A) into the rear of the

automatic tensioner via the opening at the

rear of the alternator bracket.

2.

Screw the bolt in until the automatic

tensioner locks.

3.

Place a spanner on the nut (C) on the

alternator and turn the engine clockwise.

Note:

Turning the nut anti-clockwise may cause the

alternator nut to work loose.

If the tensioner slips while cranking, it can be pre-

tensioned a little by turning the automatic

tensioner anti-clockwise (B) whilst securing the

bolt (A).

the opening at the bottom of the flywheel

housing such that the pinion engages the

starter ring gear.
