Assembly instructions for an Erde 102 trailer

We find that some people have problems following the instructions Erde supply with their trailers. To make this easier we have put together our own illustrated instructions for assembling Erde trailers.

Tools needed:
10mm spanner/socket.
13mm spanner/socket.
17mm spanner/socket.
Flat-head screwdriver.
Socket extension.
Things to remember:
Do not tighten bolts until they are all correctly fitted.
Most nuts are captive nuts to speed up assembly.
Click on a number to quickly jump to a step.
1. Start with the floor pan upside down and fit the axle to the floor pan.
2. Fit the drawbar to the axle.
3. Attach the drawbar to the floor pan.
4. Fasten the light bar to the floor pan using the single bolt in the middle.
5. Attach the cables to the lights.
6. Fit the wheels.
7. Tighten all bolts under the trailer except the centre bolt on the light panel.
8. Turn the trailer the correct way up.
9. Fit the side panels.
10. Fit the front panel.
11. Fit the tailgate.
12. Fit the mudguards.
13. Tighten all Bolts.
Please note: Due to vibration bolts can rattle loose, all bolts MUST be checked after 60 miles.
It is also recommended to check lights, couplings, wheels, and wheel bearings BEFORE every long journey.

1. Start with the floor pan upside down and attach the axle to it using bolts and spring washers.

There are pre-drilled holes with captive nuts on each side of the floor pan to make this easier. Use a 17mm socket to tighten these four bolts.

2. Remove the bolt from the rear end of the drawbar, then use it to attach the drawbar to the centre support of the axle.

Thread the two coloured wires through the drawbar before slotting it into the centre support of the axle. The large bolt from the end of the drawbar passes through both the drawbar and axle, and is secured with a washer and nylock nut. You will need a 17mm spanner and socket to tighten this. Remember this is the pivot point for the trailers tipping feature, so don’t over tighten it.

3. Attach the drawbar to the floor pan using the tipping bracket.

The tipping bracket must be fitted to the underside of the floor pan as shown below. At the centre point of the front edge are pre-drilled holes with captive nuts where it mounts. A 13mm socket or spanner is required for this.

A latch on the drawbar holds the floor pan and drawbar together using the tipping bracket.


4. Fasten the rear light bar to the floor pan.

It helps to angle the light bar away from the trailer to make it easier to hook under the lip of the floor pan. Straighten it up when you get it into the correct position.

When in position, a single dome head screw though the centre of the light bar will hold it in place.

5. Attach the colour coded cables to the corresponding sockets on the reverse of the rear light bar. Each socket is marked with a coloured sticker.

Slot the cables into the sockets and then twist the coloured sheath clockwise to lock it in place. The cable will only slot into the socket in one direction, so don’t force it.

6. Fit the wheels.

Remember that the rounded ends of the wheel nuts face inwards. If they are fitted facing outwards you will not be able to tighten them up correctly. A 17mm socket or wheel wrench will be required.

7. Tighten all bolts under the trailer except the centre bolt on light panel.

8. Turn the trailer the correct way up. This may require two people.

9. Fit the side panels. It is easiest to mount them at the back first and then lower the front into position.

Hook the rear of the side panel over the edge of the light bar before lowering the front of the panel.

Lower the front of the side panels into position. Where you hooked the side panels over the light bar you will notice a small hole, a 10mm bolt passes through this hole and screws into the light bar.

One 13mm bolt at the front and two at the rear of each side panel will hold them in place. The two 13mm bolts at the rear of each panel also secure the light bar.

10. Slot the front panel into place, do not completely tighten the bolts at this stage.


11. Fit the tailgate.

The tailgate hinge simply slides together.


12. Fit the mudguards.

Remember to fit the mudguard reinforcement plates. These prevent bolt heads from pulling through the thin metal of the mudguards.

The mudguards mount onto pre-drilled holes in the side of the floor pan, located just above the wheels. A 13mm socket with extension is needed to reach these bolts.

13. Tighten all Bolts.

Again, remember to perform a thorough check of all nuts, bolts, wheels, bearings and lights after the first 60 miles. Vibrations can cause slackening of nuts and bolts in new trailers, so it is very important you perform this check.
