Changing Wheels on a Trailer with Tandem Springs
DANGER: ‐
NEVER work under a trailer which is unsupported.
NEVER remove more than one wheel at a time.
ALWAYS stand clear of the trailer with the wheel removed.
FAILURE TO FOLLOW THIS PROCEDURE COULD RESULT IN SERIOUS INJURY OR DEATH
1. If loaded, empty the trailer.
2. Ensure trailer is parked on firm level ground.
3. Check trailer is securely hitched to the tractor, apply the tractor park brake, stop the
engine and remove the key.
4. Ensure brakes are applied and wheels which are not being removed are chocked.
5. Slightly loosen the wheel nuts of the wheel to be removed.
6. Place jack below axle, as close to wheel as possible ensuring to leave room for an axle
stand between the jack and the wheel.
Minimum jack & axle stand ratings must be equal to or greater than axle weight (e.g. for
10 tonne axle weight jack must be minimum 10 tonne). The use of a bottle jack is not
recommended
