Removing

1.Swing the seat completely out of the way.

2.Release the mechanical link between the left park brake and the brake lever.

3.Release the dampeners (23) and springs (17) from the tubular shafts (31, 33) by removing the bolts

(16)- each with two nuts (22) - spacers (21) and washers (11).

4.Release the front end of the ball joints (32) from the tubular shafts (31, 33) by removing the bolts (14), nuts (22) and washers (11).

6.Remove the bolt to the park brake arm (on the right side of the park brake shaft). Remove the arm and the released washers from the park brake shaft.

7.Pull out the park brake shaft and lever to the left. When the shaft is pulled out, the tubular shafts, ﬁrst

(33)and then (31), will be freed.

8.Disconnect the cable connection to the switch and remove the tubular shaft.

Fitting

The ﬁtting procedure is the reverse of the removal procedure.

Pay particular attention to the following:

•Check and position the switches before ﬁtting the tubular shaft.

•Position the switches so that there is a click when the inner ﬂat surface of the arm continuation shaft (5) passes over the outside corner of the tubular shaft’s lever mount.

•Check the setting of the linkages (see Hydraulic System\Hydraulic Pump\Linkage Adjustment).

•Check the setting of the reverse detent spring (see Hydraulic System\Hydraulic Pump\Reverse Spring Detent Adjustment).
