Wheel Bolt Tightening

When refitting a trailers' road wheels it is ESSENTIAL that the wheel nuts/bolts are tightened to the recommended torque figure and in the correct sequence. To neglect this is too run the risk of either the nuts/bolts working loose and the wheel coming off (not tight enough), or damage to and possible shearing of the nut/bolt (over tightened).

The sequences necessary to correctly carry out this work are as follows:-

Always use the sequence 1, 2, 3, 4 (or north, south, east, west) - NOT clockwise or anti- clockwise.

It is ESSENTIAL that the torque settings are re-checked after the first 25 miles or 50 km and subsequently before each journey.
