How to easily tell a 12-inch weld ring from a 10-inch?

People sometimes ask how to tell the difference between a 10-inch and 12-inch weld ring. Put simply, it is the number of holes: 10-inch weld rings usually have 4 holes, whereas 12-inch has 5 holes.

Dry Assembly Instructions

Welding brackets are difficult to mount correctly. Therefore, the following steps can help DIY caravanners.

• Assemble the electric backing plate onto the weld ring
• Place the drum over the axle profile dry (without grease).
• Lock the axle nut so that the drum is in position.
• Adjust brake shoes, so shoes almost lock into the drum.
• Adjust the drum and backing plate, so both parts are concentric on the axle.
• Tack the weld ring into position at 4 points and de-assemble.
• After de-assembly, finish welding the weld ring into place.
