Trailer and Caravan 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:-
Torque figures : Wheel Bolts
| AL-KO | Indespension |
|---|---|
| M10 - 40 lb. Ft / 54 Nm | M12 - 55 lb. Ft / 74 Nm |
| M12 - 65 lb. Ft / 88 Nm | M14 - 60 lb. Ft / 81 Nm |
| M14 -108 lb. Ft /146 Nm | |
| Ifor Williams | Avonride |
| M12 - 65 lb. Ft / 88 Nm } used with | M12 - 65 lb. Ft / 88 Nm |
| Torque figures: Nuts | |
| Peak Trailers | Indespension |
| M12 x 1.5 - 75 lb. Ft / 102 Nm | 3/8" UNF - 42 lb. Ft / 57 Nm |
| M16 x 1.5 - 145 lb. Ft / 197 Nm | 7/16" UNF - 50 lb. Ft / 67 Nm |
| 3/8" UNF - 45 lb. Ft / 61Nm | 1/2" UNF - 56 lb. Ft / 76 Nm |
| 1/2" UNF - 80 lb. Ft / 109 Nm | 5/8" UNF - 85 lb. Ft / 115 Nm |
| Avonride | |
| 1/2" UNF - 65 lb. Ft / 88 Nm | 5/8" UNF - 79 lb. Ft / 108 Nm |
It is ESSENTIAL that the torque settings are re-checked after the first 25 miles or 50 km and subsequently before each journey.
